INTERNAL ASSESSMENT PACKET

GENERAL INFORMATION ABOUT THE I.A.

Internal assessment is an integral part of the course and is compulsory for both SL and HL students. It enables students to demonstrate the application of their skills and knowledge, and to pursue their personal interests, without the time limitations and other constraints that are associated with written examinations. The internal assessment requirements at SL and at HL are the same. The work submitted for internal assessment must be the student’s own work. The teacher should play an important role during both the planning stage and the period when the student is working on the internally assessed work. It is the responsibility of the teacher to ensure that students are familiar with:

• the requirements of the type of work to be internally assessed • the IB animal experimentation policy and the biology course safety guidelines • the assessment criteria—students must understand that the work submitted for assessment must address

these criteria effectively. • As part of the learning process, teachers should read and give advice to students on one draft of the work.

The teacher should provide oral or written advice on how the work could be improved, but not edit the draft. The next version handed to the teacher must be the final version for submission.

• All work submitted to the IB for moderation or assessment must be authenticated by a teacher, and must not include any known instances of suspected or confirmed academic misconduct. Each student must confirm that the work is his or her authentic work and constitutes the final version of that work. Once a student has officially submitted the final version of the work it cannot be retracted. The requirement to confirm the authenticity of work applies to the work of all students, not just the sample work that will be submitted to the IB for the purpose of moderation. For further details refer to the IB publication Academic honesty (2011), The Diploma Programme: From principles into practice (2009) and the relevant articles in General regulations: Diploma Programme (2011).

AUTHENTICITYAuthenticity may be checked by discussion with the student on the content of the work, and scrutiny of one or more of the following:• the student’s initial proposal • the first draft of the written work • the references cited • the style of writing compared with work known to be that of the student • the analysis of the work by a web-based plagiarism detection service such as SAFEASSIGN or

http://www.turnitin.com. • The same piece of work cannot be submitted to meet the requirements of both the internal

assessment and the extended essay.

GROUP WORKEach investigation is an individual piece of work based on different data collected or measurements generated. Students should work on their own when conducting the experiment and collecting data.

SAFETY AND ANIMAL EXPERIMENTATION POLICYIt is a basic responsibility of everyone involved to make safety and health an ongoing commitment. It is the responsibility of all students to read, understand and abide the rules posted in the Safety contract signed at the beginning of the school year. Please refer as needed. All students should report any and all accidents or incidents to the teacher.

Page 2 of 18

INTERNAL ASSESSMENT PACKET IB standards for work in schools are more stringent than those of university and R&D research committees as we are not carrying out essential, groundbreaking research. Practical work in schools has other purposes such as reinforcing concepts and teaching practical skills and techniques. Even in a practically based extended essay the work will not be fundamental research.

• _Any planned and actual experimentation involving animals must be subject to approval following a discussion between teacher and student(s) based on the IB animal experimentation policy.

• _Experiments involving animals must be based on observing and measuring aspects of natural animal behavior. Any experimentation should not result in any pain or undue stress on any animal (vertebrate or invertebrate) or compromise its health in any way. Therefore experiments that administer drugs or medicines or manipulate the environment or diet beyond that easily tolerated by the animal are unacceptable. Experiments resulting in the death of any animal are unacceptable.

• _Any experimentation involving humans must be with their written permission and must follow the above guidelines. Experiments involving body fluids must not be performed due to the risk of the transmission of blood-borne pathogens. When working with humans, you must have them sign a consent form and if under 18 then the parent must sign as well. Human participant projects are tricky and take a while. I discourage you in doing them but if still interested, come and see me and I will give you the consent forms and guidelines.

GRADING CRITERIAInternal assessment is an integral part of the biology course, contributing 20% to the final assessment in the SL and the HL courses. Student work is internally assessed by the teacher and externally moderated by the IB. The performance in internal assessment at both SL and HL is marked against common assessment criteria, with a total mark out of 24. For internal assessment, a number of assessment criteria have been identified. Each assessment criterion has level descriptors describing specific achievement levels, together with an appropriate range of marks. The level descriptors concentrate on positive achievement, although for the lower levels failure to achieve may be included in the description. Internally assessed work will be judged at SL and at HL against the criteria using the level descriptors.• Assessment criteria are the same for both SL and HL. • The aim is to find, for each criterion, the descriptor that conveys most accurately the level attained by the

student, using the best-fit model. A best-fit approach means that compensation should be made when a piece of work matches different aspects of a criterion at different levels. The mark awarded should be one that most fairly reflects the balance of achievement against the criterion. It is not necessary for every single aspect of a level descriptor to be met for that mark to be awarded.

• When assessing your work, I will read the level descriptors for each criterion until I reach a descriptor that most appropriately describes the level of the work being assessed. If a piece of work seems to fall between two descriptors, both descriptors will be read again and the one that more appropriately describes the student’s work will be chosen.

• Where there are two or more marks available within a level, the upper mark will be awarded if the student’s work demonstrates the qualities described to a great extent; the work may be close to achieving marks in the level above. The lower marks will be awarded if the student’s work demonstrates the qualities described to a lesser extent; the work may be close to achieving marks in the level below.

• Only whole numbers will be recorded; partial marks (fractions and decimals) are not acceptable. • The highest level descriptors do not imply faultless performance but should be achievable by a

student. Teachers should not hesitate to use the extremes if they are appropriate descriptions of the work being assessed.

• A student who attains a high achievement level in relation to one criterion will not necessarily attain high achievement levels in relation to the other criteria. Similarly, a student who attains a low achievement level for one criterion will not necessarily attain low achievement levels for the other

Page 3 of 18

INTERNAL ASSESSMENT PACKETcriteria. Teachers should not assume that the overall assessment of the students will produce any particular distribution of marks.

• The assessment criteria/Rubric is posted on Blackboard and my webpage.• There will be no pass or fail boundary, but instead on identifying the appropriate descriptor for each

assessment criterion. • The task will have the same assessment criteria for SL and HL. The five assessment criteria are personal

engagement, exploration, analysis, evaluation and communication.• The new assessment model uses five criteria to assess the final report of the individual investigation with the

following raw marks and weightings assigned: Levels of performance are described using multiple indicators per level. In many cases the indicators occur together in a specific level, but not always. Also, not all indicators are always present. This means that a candidate can demonstrate performances that fit into different levels. To accommodate this, the IB assessment models use markbands and advise examiners and teachers to use a best-fit approach in deciding the appropriate mark for a particular criterion.

WRITING AND ASSEMBLING THE PAPERNOTE: Papers not following these guidelines will not be accepted.

A. PAPER PAGE LIMITS The internal assessment task will be one scientific investigation taking about 10 hours and the write- up

should be about 6 to 12 pages long. Investigations exceeding this length will be penalized in the communication criterion as lacking in conciseness.

If the text is reduced, the appendix may be increased to allow for additional raw data, charts/graphs, or illustrations but only to a maximum paper length of 12 pages.

Write you name and candidate number on the upper, left hand side of the header.

B. THE PAPER ORDER OF COMPONENTS Note: Do NOT include a title page. Number the Pages beginning with the research question as page 1. The following are the required headings, and should be bolded and/or underlined:

1. RESEARCH QUESTION 8. CONCLUSION2. BACKGROUND INFORMATION 9. EVALUATION, IMPROVEMENTS & NEXT STEPS3. HYPOTHESIS 10. APPENDIX4. VARIABLES 11. BIBLIOGRAPHY5. APPARATUS6. METHOD7. ANALYSIS OF RESULTS

GO TO BLACKBOARD TO FIND SAMPLE IA ‘S

C. GENERAL WRITING GUIDELINES (Mechanics for formatting typed submissions) All parts of the paper must be typed/word processed in double-spaced format. (Exceptions: long

quotes, figures, legends, within literature citations). All parts written in passive voice and past tense.

Page 4 of 18

INTERNAL ASSESSMENT PACKET The paper should be concise and proper grammar, sentence structure, and punctuation should be

used throughout the paper. You must have your parent or another adult proofread it. All margins—top, bottom, sides—are not less than one inch (1") on ALL pages including appendices. Pages must be numbered. Put page numbers in the footer , which can be within the margin and the

only exception to the one inch margin. The paper must be printed in no smaller than 12 pt. type size using the font Times New Roman. Do not use footnotes. Use parenthetical citations (Last name of Author, Year). Ex: (Smith, 2016) Graphs and figures made by computer should be appropriately labeled.

CHOOSING YOUR TOPICThe task produced should be complex and commensurate with the level of the course. It should require a purposeful research question and the scientific rationale for it. The sample IA’s found on Blackboard will demonstrate that the assessment has to be rigorous and of the same standard as the assessment in other IB courses. Some of the possible tasks include:

a hands-on laboratory investigation using a spreadsheet for analysis and modeling extracting data from a database and analyzing it graphically producing a hybrid of spreadsheet/database work with a traditional hands-on investigation using a simulation provided it is interactive and open-ended.Some tasks may consist of relevant and

appropriate qualitative work combined with quantitative work.

You must also demonstrate the thinking behind your ideas using their subject knowledge. The topic should be related to Biology. The information given must be targeted at the problem rather than being a general account of the topic matter, in order to demonstrate focus on the issues at hand.

Sometimes the hardest part of doing a science project is settling on an idea. You want to select something that you will enjoy—that will inspire your curiosity. Since this is challenging for students, and everyone has different interests, we have developed this section to help you. You can also find many sources out there to help you choose a topic, but don’t be tempted to copy a procedure verbatim from the internet or from a book you find. Those sources can be used as a guide, but you need to make the procedure your own.

It is highly recommended that is your investigation is based on a published one that you put sufficient effort into developing making it your own and differentiating it from the source. If you don't the marks you can gain with under the exploration criteria will be limited.

One word of caution, before you get too attached to an idea, there is a list of sensitive project topics coming up. These projects will need special approval and they inevitably involve a significant amount of extra work. Please read this section carefully if you are planning to work with microbes or other potentially hazardous chemicals or devices.

Be sure to choose a project at the high school level or higher. Projects that are too simple, at the elementary school/middle school level, will not be accepted. Check with your teacher early to avoid this frustration if you are unsure.

Start with Your Interests! There are many categories to choose from! Make a big list of everything that interests you. Do you wonder how these things work? Whether one way of doing something is better than another? Decide whether these topics can be studied in a scientific experiment. A scientific experiment needs

All classes: please apply APA formatting. See http://apastyle.org/index.aspx. A full APA sample paper may be found here: http://supp.apa.org/style/PM6E-Corrected-Sample-Papers.pdf.

INTERNAL ASSESSMENT PACKETan independent variable (something you will manipulate) and a dependent variable (something you will measure).

You may want to use the internet to see examples of past projects or, even better, find out what’s really being researched in the scientific community right now – These topics can serve as inspiration, but you should not duplicate someone else’s research exactly. Instead, think of ways to alter these examples so that they become meaningful to your experience and project.

Be ready to provide a rationale for your choice—how can your project be used to further knowledge, build upon good practice, or improve people’s way of life? Present sound reasoning for your project choice, and be prepared to explain the benefits of your experiment.

Here are a few sources where you may find lists of topic titles or general topic ideas: Look for topics related to Biology.

Before you settle on a topic, GO to the library to determine how much relevant research is available. You need to see what information is out there that can help you develop a sound hypothesis and detailed procedure. If you have trouble finding research that is relevant to your idea, then you may need to expand your search or alter your plan.

So go to your local or school library to see what scholarly sources you can find . The librarian can walk you through several electronic databases, which contain reliable resources that may be used to narrow down your topic and conduct background research.

Why is Research important to do BEFORE you start your experiment? Learn about your topic! You need enough background information on your topic to ask an insightful

question, form a logical hypothesis, and validate your experiment and results. You need education and specific information regarding your subject being studied. You need to learn about the potential dangers and best materials to use while conducting your

experiment. You need to decide what equipment to use to collect data, and how to analyze your data findings. You can elaborate on theories on which your experiment is based, and strengthen your written report. Why is your topic meaningful? Learning about your topic helps you justify your work is an important

component of science research. How does your work affect the world around us? Why is your project worth doing? How might your work be of benefit to your communities? Your research will help strengthen your rationale for these questions, and make your work more fulfilling and significant.

You can also access the W-L library’s data bases through Blackboard: Log onto Blackboard, Click on the For Students Link, Click on Secondary Online. You should be able to log on through Blackboard without a password.

If you are having problems with your Blackboard account, from the library site of the W-L Home Web Page, you might try these databases and passwords: e Library science with the remote access login: arlington2, and the password student, or Gale Cengage Secondary particularly “Science in Context, with the remote access password: va_schools.You can also access www.questiaschool.com where your login is as follows:Username: student’sID#@questia.com Password: firstname (lowercase) . . .

ORDERING AND PURCHASING MATERIALSYou can purchase materials and organisms from science supplies companies like www.carolina.com or www.freyscientific.com. It is imperative, that once your project proposal gets approved, you order your materials. DO NOT WAIT UNITL THE LAST MINUTE TO PLACE YOUR ORDERS. Allow two weeks for delivery after you submit order and payment. Check with me first to see what equipment is available to borrow from school, before ordering. Organisms and Chemicals with restrictions, can be ordered through me, but you need to fill out a form and give payment with enough time for processing.

TOPIC & RESEARCH PLANSUMMARY

This is the format of your research plan. Refer to the template on blackboard.A. Research Question [Phrased in a similar format to “What is the effect of the IV upon the DV in XXXX?”.

XXXX refers to the organism or biological material being studied.]B. Background Information including:

a. Purpose/Problem and Rationale Scientific theory is used to describe and explain how the chosen IV affects changes in the

organism/biological material being dealt with. What is the purpose of your experiment. It must have a meaningful, purposeful research question and

the scientific rationale for it. Why did you pick this topic and why is this topic important to understand as a student and as a global citizen?

The justification given for choosing the research question and/or the topic under investigation demonstrates personal significance, interest or curiosity. Explain why the chosen DV is a good measure of change in the organism/biological material

C. Hypothesis The hypothesis should be based on the theory identified in the background. A graph should be sketched to illustrate the hypothesis] Where possible the hypothesis should be

quantified, e.g. It is expected that the optimum pH for the activity of catalase to be 6.2] A hypothesis is an educated guess presuming the outcome of the experiment. Form a hypothesis after

your background research and definition of the problem. Write in “If…then…because” format, present tense.

D. Variables Include:

o I.V. (Independent variable) (Manipulated variable): The condition that a scientist changes when conducting an experiment. This is the only variable that is altered, so it is the variable that causes change. The I.V. starts the experiment and is the first/only thing that is changed by the student. (“I” change the “I”V)!

o D.V. (Dependent variable) (Responding variable): The variable measured by the researcher. The D.V. depends on the I.V. It is affected by the independent variable and is observed and measured.

o Experimental groups: The groups of participants or subjects receiving the variable or treatment.o Control group: The group not receiving the variable or treatment. The control group establishes a

baseline for the experiment.

Page 9 of 18

INTERNAL ASSESSMENT PACKET(The researcher compares the performance of the experimental group with that of the control group to determine if the independent variable causes a change or effect).

o Controlled variables: Those variables that will remain the same throughout the experiment for all groups.

You have the choice of doing 5 IV values x 10-20 repeats format or 2 IV values for a population x 15 repeats format or 5 IV value X 5 different times each value x 5 repeats each

E. Apparatus List all equipment/materials/organisms you are planning on using. Include all items, quantities, concentrations, volumes, masses etc., for measuring equipment

uncertaintiesF. Method

Briefly describe the method used to manipulate the IV, including specific details of range or increments.

Each control and uncontrolled variable identified in the variables table should be addressed in the method.

Make sure the method is clear, specific and easily replicated. The method clearly communicates the reasons why each step is the method is appropriate and

necessary. If the chosen method is based on or adapted from a published protocol then the original protocol must

be cited. Describe how you will collect your data and how you will analyse it, including the statistics your are

planning on using.G. Safety and Ethical Considerations

Comment on possible hazards, environmental, ethical and social impacts of the work, and say how they will dealt with to minimise the impact.

H. Bibliography—It is a list of the literature cited in the text. Citations are used effectively to support the background. Textbooks should be the first port of call when looking for a citation. There must be a minimum of five peer-reviewed/scholarly sources. Each must be cited at least once in the body of the paper. Use APA style. The list is alphabetical by the last name of the first author of a citation. Use single spacing within each

listing and double space between the listings. See example below The American Psychological Association Style (APA) style is the most widely accepted and preferred

way of presenting documentation and supporting information when it comes to writing, especially in terms of research and reference writing. The APA homepage is http://apastyle.org/index.aspx. A sample APA paper may be found here: http://apastyle.org/index.aspx.

The literature cited is a list of all books, publications, and communications cited in your paper. The listing is alphabetical by the last name of the first author of a citation. “Scholarly” sources include peer-reviewed reports, articles, books, etc. Those you reference should be accessible from library digital archives (files, databases, books, etc., available for inspection, digitized and on-line for easy access and convenience) or refereed on-line journals. Ask librarians for help if uncertain!

One of your non-scholarly sources should be the source where you found your idea for your experiment. Be sure your experiment is not just a copy of an experiment that was done before.

Students may use www.bibme.com to easily put sources in the correct format. Also see www.citationmachine.net. You may ask librarians for help with finding other online tools for proper referencing.

Wording in your reports and submissions should be paraphrased in your own words. Direct quotes should be in quotation marks. Watch out for plagiarism in your final report, I will be checking all assignments with SafeAssign!

Written in the passive voice the subject is the recipient of the action—the subject is placed at the end of the sentence or omitted.

o Example of passive voice: Incorrect: “The scientist placed 50ml of water in the beaker” Correct: "50ml of water were placed in the beaker ".

o Passive voice sentences include a be-verb such as am, is, was, were, are or been. Include citations throughout the body using the sources in your cited literature. The introduction starts with a broad basis and then narrows it down to your particular field of study ,

explaining the rationale for each step and decision. You are attempting to inform the reader about the rationale behind the work, justifying why your

work is an essential component of research in the field. You can include information from previous research, explanations or theories, methods or equations. This should be as concise as possible and give an overall review of the paper. It works upon the

principle of introducing the topic of the paper and setting it into a broad context, gradually narrowing down to a hypothesis. A good introduction explains how you mean to solve the research problem, and creates ‘leads’ to make the reader want to delve further into your work.

VARIABLES

PROCEDURE & MATERIALS [The method must describe how to manipulate the IV, including specific details of range or

increments.]

[The method for recording results, including units and uncertainty of tools should be described.]

[Each control and uncontrolled variable identified in the variables table should be addressed in the method.]

[A diagram or photo of the experimental setup helps to make a complex equipment setup clear]

[Annotate/label diagrams and photos to give them value and explain their relevance. Annotations maybe done in the main text as an alternative to including annotations in the diagram.]

[Make sure the method is clear, specific and easily replicated. This is best done by getting a person not familiar with your work to read through the method and the explain it back to you.]

[The method clearly communicates the reasons why each step is the method is appropriate and necessary. Much of this explanation might already be addressed in the second column of the variables table.]

[If the chosen method is based on or adapted from a published protocol then the original protocol must be cited.]

Pointers: Do not include any results in this section . Use paragraph format, not cookbook format. Use Passive Voice; Example: (Passive) “The chemical was placed in a solution” (vs. Active): “The

experimenter placed the chemical in the solution”. Include precise quantities and descriptions of materials and equipment .

Page 12 of 18

INTERNAL ASSESSMENT PACKET Incorporate materials used (and their precise measurements) into the paragraph of your procedure .

Example: “A solution of 50ml of vinegar was used to cover one egg”. Include descriptions, types, and quantities of equipment, chemicals, organisms, etc. (be specific!).

ANALYSIS OF RESULTSThis section consists of a passage of writing interspersed with tables and graphs. The purpose of the analysis is to interpret the data so that a valid and detailed conclusion to the research question can be deduced later on in the report.

[Graphs, tables, and images should be included as close as possible to their first reference in the analysis. If a graph is not used to support the analysis it should not be included.]

Raw data and calculations should be referred to – if there is a lot of raw data place it in a appendix.

[Qualitative data] [This is important as it demonstrates critical thinking]Comment on:

- Variation within the organism/biological material being are dealt with- Colour, texture, shape, size, heat changes- Anything notice that might affect results, but you can’t put a number on]

[Included data tables] Raw and processed data maybe often be separated into different tables. However it is common practise to include mean and standard deviation as additional columns in the table that includes the data upon which they are based. This is a summary data table.

[Clear table(s) with:- Title – “Table 1: … “ this should refer to the headers- IV should ideally be in the first column, DV should occupy subsequent columns- Descriptive headers, e.g. not just temp, but temp of the mixture of amylase and starch- Units and uncertainties]

Pointers: [When quoting units use the same units as for the uncertainties, this is good practise.]

[If uncertainties differ, i.e. is larger than the uncertainty quoted in the apparatus list then a rationale must be given]

[Use seconds rather than minutes:seconds if the variable is time. It is clearer and later avoids human errors in data processing.]

[If stated in the method that measurements are to be taken, even if only to monitor a control variable, it still needs to be included in the raw data.]

[Name other students who collaborated in the data collection.]

[Calculations]

[Are calculations needed to make calculations to determine the DV? For example:- Rate of reaction = volume, distance etc. / time- % Change = (end – start) / start x 100

Page 13 of 18

INTERNAL ASSESSMENT PACKET- Anything else that is appropriate?]

[If calculations are made to determine the DV then remove the uncertainty from the header. Uncertainty is now variable and cannot be expressed as an absolute value.]

[Show calculations and sample workings. This is most easily done by screen shots of MS Excel formula.]

[The significant figures in the calculated DV should match the significant figures in the raw data. For example if the uncertainty of raw data is ±0.01g then the % change should be 0.00 if the maximum value is greater than 1 and less than 10 and 00.0 if the maximum value is greater than 10, but less than 100.]

[Work out the mean and standard deviation of the calculated DV for each value of the IV. If no calculation is made to determine the DV then simply the mean and standard deviation of the raw data.]

[The mean and standard deviations should be quoted in the same units and the same uncertainty, if present, as the data they are calculated from.

[standard deviation should only be calculated if a minimum of 5 repeats is available]

[The mean should be quoted to the same number of decimal places as the data it is are calculated from, the standard deviation maybe quoted to an additional decimal place for clarity]

For statistical tests:- phrase the hypothesis in the null/alternate hypothesis format, if appropriate- explain the steps in the calculation- explain the meaning of the calculated values- in the analysis explain what support the test offers for the research question]

[For non-standard calculations give a rationale for your chosen method.]

Statistical Analysis Pointers: Collect as much data as possible so you can run statistical analysis on your data that is meaningful. Key descriptive statistics include the mean (the arithmetic average) and the standard deviation (the

amount of dispersion in the measures of a particular variable). You can use these descriptive statistics, for example, to summarize average rates of growth in plants under different climate conditions.

Use the appropriate inferential statistics for your experiment to analyze your data and draw conclusions.

Inferential statistics refer to the range of procedures used for drawing conclusions about the data in an experiment.

Popular inferential techniques include tests of statistical significance (chi-square or t-test), analysis of variance (anova test), factor analysis and linear regression.

The nature of your science project and the types of questions you want to answer will help determine the appropriate inferential statistical methods.

Many statistical analysis tools are available in spreadsheet programs—all you do is input the data and select the statistical test you want to complete; the program will provide a value that you can interpret to determine the significance of your data.

Often statistical tests provide a p-value that allows you to say whether a null hypothesis is supported or rejected.o A null hypothesis proposes that there is no significant difference between experimental

groups, or between an experimental group and a control group.Page 14 of 18

INTERNAL ASSESSMENT PACKETo A supported null hypothesis indicates there was no significant effect of your I.V.o A rejected null hypothesis indicates there was a difference between groups, probably

not due to random chance.

[Included graphs] [For almost all investigations an appropriate graph can be added]

[Graph(s) should be of processed data, not raw data] i.e. means

[At least one graph should resemble the one used in the hypothesis]

[Graph axis labels, units and uncertainty should directly reflect the headers used in the processed data table]

[Numbers displayed on the axes should be to same number of decimal places as the data they are based on.]

[Graph titles should be descriptive and refer to the axes labels]

[Graphs should occupy a minimum of ½ a page, the larger it is, the easier it is to read]

[The default choice of graph should be a scatter plot. If comparing means, i.e. the data is in the 2 IV values x 15 repeats format, then bar charts maybe chosen instead, though a scatter plot will work]

[If standard deviation is available error bars based upon it should be added, if not error bars should be base upon the range.]

[The source of the error bars should be explicitly declared. It is recommended that this is included directly under the title, but in a smaller font.]

[If the data is in the 5 IV values x 5 repeats format and a trend is apparent then a straight lines joining the data points should be added.]

[If looking for trend/correlation, i.e. the data is in the 5 IV values x 5 repeats format] [Comment on the processed/calculated data:

- Is there a pattern to the data? Positive/negative correlation, straight line, bell shaped curve, u-shaped, s-shaped, does it plateau?

- Quote values in the description.

[Comment on error bars:- How large are the error bars? The smaller they are the stronger the correlation is.- Are there any anomalies in the raw data that explain abnormal large error bars?- Do the size of the error bars make a valid conclusion difficult to reach?

[If comparing means, i.e. the data is in the 2 IV values x 15 repeats format] [Comment on the processed data:

- Is one bar on the chart/mean value is higher than the other? Quote values and names of the IV values.]

[Comment on error bars:- Is there an overlap of error bars? The larger the overlap the less likely the means are to be

significantly different from each other.- Does a t-test confirm the observations made in the previous point?

Page 15 of 18

INTERNAL ASSESSMENT PACKET- Are the error bars similarly sized? If different does this indicate possible errors or simply natural

variation?- Are there any anomalies in the raw data that explain abnormal large error bars?- Do the size of the error bars make a valid conclusion difficult to reach? This maybe already

answered if the t-test is available]

[For all][Comments on the raw data should be in reference to anomalies or unusual trends, in the main when talking about data the focus should be processed data and mean values.]

[Comment on the qualitative data:- What impact might the qualitative data of had upon the findings?- Does it make the measurements likely to be skewed, i.e. all too large or too small?- Does the qualitative data indicate a possible reason for the natural variation seen in the data?- Does the qualitative data make it more difficult to come to a valid conclusion?]

[Discussion of the size of the uncertainties compared to the magnitude of the data collected. Is the validity of the conclusion affected?]

CONCLUSIONRefer back to scientific theory and the citation(s):

- What do the results indicate in terms of the IV and DV?- How does the DV link to, and help answer, the research question?- Does the data support accepted theory?- Are the results consistent with published data?- Discuss the data in relation to scientific theory.]

Justify what is judged to be the level of support (use the correct language) for the hypothesis by referring to points/arguments made previously in the analysis.

Refer back to the research question, better restate it and discuss how well it has been possible to answer it

APPENDIXThe appendix is for supplementary information. Raw data too lengthy to be included in the results section of the text may be placed here only if absolutely necessary for understanding the paper. Remember that summary data should be in the “Results” section. All materials in this section must meet the same requirements as the text of the paper.

TOPICS TO AVOID

The following contains examples of topics that you will want to avoid for your science fair project.Topic to Avoid Why?

Any topic that boils down to a simple preference or taste comparison. For example, "Which tastes better: Coke or Pepsi?"

Such experiments don't involve the kinds of numerical measurements we want in a science fair project. They are more of a survey than an experiment.

Most consumer product testing of the "Which is best?" type. This includes comparisons of popcorn, bubblegum, make-up, detergents, cleaning products, and paper towels.

These projects are more of a marketing project and only have scientific validity if the investigator fully understands the science behind why the product works and applies that understanding to the experiment. While many consumer products are easy to use, the science behind them is often at the level of a graduate student in college.

Any topic that requires people to recall things they did in the past.

The data tends to be unreliable.

Effect of music or talking on plants Difficult to measure.Effect of running, music, video games, or almost anything on blood pressure

The result is either obvious (the heart beats faster when you run) or difficult to measure with proper controls (the effect of music).

Effect of color on memory, emotion, mood, taste, Highly subjective and difficult to measure.

Page 17 of 18

INTERNAL ASSESSMENT PACKETstrength, etc.Any topic that requires measurements that will be extremely difficult to make or repeat, given your equipment.

Without measurement, you can't do science.

Any topic that requires dangerous, hard to find, expensive, or illegal materials.

We care about your safety and your parents' pocketbook.

Graphology or handwriting analysis Questionable scientific validity.Astrology or ESP No scientific validity.Any project in violation of state law, federal law, state science fair rules, or International Science & Engineering Fair rules.

In brief, you may not do a project that involves:working with bacteria (except in a designated, qualified lab), unacceptable risk (physical or psychological) to a human subject, collection of tissue samples from living humans or vertebrate animals, drugging, pain, injury to a live vertebrate animal, or use of illegal or prohibited materials

YOU’VE CHOSEN A TOPIC? HOW DOES YOUR TOPIC MEASURE UP?

The following table will help you check to see if the research topic/question is both narrow and interesting enough to work.

What Makes a Good Science Fair Question For a Good Topic, You Should Answer "Yes" to AllIs the topic interesting enough to read about AND work on for the next couple months? Yes / No

Can you find at least 5 sources of written information on the subject? Yes / No

Can you measure changes to the important variables using a number that represents a quantity such as a count, length, width, weight, voltage, time, etc.? Or, just as good, is your variable one that is simply present or not present?For example,

o Lights ON in one trial, then lights OFF in another trial,

o Incremental increases of your variable.

Yes / No

If your data is qualitative, are you able to make a scale to convert it to quantitative data? Yes / No

Can you control other factors that might influence the variables, so that they do not interfere with your experiment?
