Inquiry Events

Write It/ Do ItWrite It/ Do ItThe purpose of this event is to test the ability

of two team members to communicate instructions for building a device or structure.

Model structures may use almost any regular everyday household/classroom items, from office supplies to legos or other blocks.

Write It/ Do It- Write It/ Do It- the competitionthe competition

Partners are isolated from each other in different rooms

The role of partner 1 is to write clear and concise directions for building a structure or device that he/she is observing in 25 minutes

The role of the 2nd partner is to read the directions written by partner 1 and attempt to recreate the structure or device as described in 20 minutes or less

Write It/ Do It- Write It/ Do It- Writer TipsWriter Tips

Bring a writing instrument (you’d be surprised!)Write the description as a series of numbered steps

that the builder should take to build the structure or device

Use descriptors like color, shape, and orientation of pieces to assist the builder in putting the pieces together correctly

Written description may only contain words,numerals, single letters, and common punctuation and editing symbols that can be obtained with 1 key or shift + 1 key on a common keyboard - symbols, drawings and diagrams are not allowed.

Write It/ Do It- Write It/ Do It- Writer TipsWriter Tips

Write fast!Every few steps clearly note what the structure

should look like at that point in building, to help the builder know he/she is on the right track

Keys/codes are not allowed and abbreviations must be defined at the beginning or when first used

Some teams prefer that the writer start with a list of pieces and colors and abbreviations they can use in the steps

Write It/ Do It- Write It/ Do It- Builder TipsBuilder Tips

Bring a writing instrumentBriefly read through the entire description

first If a materials list was provided by the writer

then compare each of the materials on the list with those that are present at the station

Begin building carefully, rechecking piece after piece

Pace yourself…..20 minutes goes quickly

Write It/ Do It- Write It/ Do It- ScoringScoring

A point is earned for each piece(s) that have been properly connected and in the proper location as in the original model.

The team who builds the structure or device closest to the original wins.

A 1% penalty is assessed for each infraction of rules (using symbols, diagrams, drawings, unlabeled abbreviations).

Tiebreaker- time for the construction phase

Experimental DesignExperimental DesignA group of up to 3 students per team are

given a problem question around which they must design and carry out an experiment using only the materials that they have been provided. They then must analyze the data collected and draw up a summary of their findings.

Experimental Design-Experimental Design-the competitionthe competition

Supervisor provides each team with identical sets of materials at a central distribution center or in a container.

Supervisor will provide all teams with a list of materials and problem question designed to narrow the scope of the experiments generated

The experiment conducted MUST explore the relationship between an independent and dependent variable.

Experimental Design-Experimental Design-the competitionthe competition

Supervisor will provide students with an answer packet in which they will record their results and write up their experiment.

Students must bring goggles and a writing instrument

Students should also bring a timer, ruler, and a non-programmable calculator (should be scientific for easier standard deviation and slope calculations)

Experimental Design-Experimental Design-the DO’sthe DO’s

Keep the experiment simple, elaboration invites difficulties to come up

Split up the tasks, while some members of the group are running the experiment another member may begin writing up the beginning of the report – use the rubric to help divide up tasks

The group needs to pace themselves carefully otherwise time may run out

Experimental Design-Experimental Design-the Don’tsthe Don’ts

Do not leave out a section on the lab writeup unless you are completely unsure what belongs in that spot

Don’t write a half procedure or write only half the variable information etc. Be clear so that anyone could replicate this experiment

Procedure, graphs, and data table are worth the most points – don’t skimp on these areas!

Experimental Design-Experimental Design-ScoringScoring

All experimental design writeups will be scored according to the distribution of points as written at the bottom of the rules page

The team with the highest total points winsTiebreakers-total points for

◦ 1-variables◦ 2-procedure◦ 3-analysis of results◦ 4-graph◦ 5-data table

Sumo Bots - constructionSumo Bots - construction

Maximum dimensions: 40cm x 40cm x 40cm at any time in the competition

Maximum weight: 2.0 kg, including batteries

Maximum voltage of all batteries located inside robot: 14.4 volts

Sumo Bots - constructionSumo Bots - construction

Must be radio controlled (no wires or tethers)

Must operate on 3 frequenciesMay have devices to remove other robot

from ring, but may not intentionally damage opponent’s robot

No projectiles, no flames, no magnets, no sharp objects

Sumo Bots – the competitionSumo Bots – the competition

◦To compete, robots go head-to-head in tournament fashion

◦Double elimination with random pairings first round

◦The “ring” will be 5ft x 5ft square with designated starting points in opposite corners

Sumo Bots – scoringSumo Bots – scoring

◦Teams have 2 minutes to force the opponent’s robot out of the ring

◦If no one “wins” after 2 minutes, the lighter robot is declared the victor

◦Robots are ranked by number of wins◦Robots that don’t meet specs will not compete against robots that meet specs

Technical Problem SolvingTechnical Problem Solving Students will visit a series of up to 5 lab stations that will

require them to use mathematics and science reasoning skills to solve a number of different problems that stem from all areas of science including biology, chemistry, physics, and earth science. In this event probes will be used at a minimum of 1 station at the state level of competition.

Technical Problem Solving- Technical Problem Solving- the competitionthe competition

Students work as a pair Series of up to 5 lab stations will be set up Each station will require that students do the following:

◦ Use mathematical expressions◦ Apply statistical analysis◦ Use correct metric units if making measurements◦ Use correct significant figures

At least one station at the state competition will use probeware. Possible probes include:◦ Temperature, voltage, light, gas pressure, pH, motion detector,

photogate Data will be collected and analyzed

Technical Problem Solving- Technical Problem Solving- the Do’sthe Do’s

Bring a non-programmable, non-graphing calculator, chemical splash goggles, pencil

Students should show all equations that they used to solve any of the problems on their answer sheet – if answers are not supported, they may not be graded

Assign students to this event who are good problem-solvers and think quickly on their feet

Have students look at sample data from teacher’s editions of lab manuals and then analyze the data

Make sure students know how to use the probes and what kinds of data the probes can produce

Technical Problem Solving- Technical Problem Solving- the Don’tsthe Don’ts

Don’t bring any additional resources, the supervisor will provide any lab equipment and in some cases a list of equations/formulas/constants

Don’t put students on this event who have not completed at least 3 years of HS science (through physics), unless absolutely necessary

Technical Problem Solving- Technical Problem Solving- ScoringScoring

Each problem question will carry an assigned point value based on the level of difficulty

Points are awarded based upon a correct response Points deducted for:

◦ Improper metric units if measuring◦ Improper sig figs

No points given for answers not supported by the data and calculations

Tiebreaker-will be selected problems determined by the supervisor in advance

Look online for old practical data gathering/practical problem solving event tests, these questions could be examples of things students could see

Basically, anything goes!
