• Qualitative descriptions (Mary has red hair.) Qualitative descriptions (Mary has red hair.) Quantitative numbers (Mary was walking two dogs today.) Quantitative numbers (Mary was walking two dogs today.) When doing observations we ask: When doing observations we ask: Who is that Who is that What is that What is that When is that happening When is that happening Where is that taking place Where is that taking place

• Observation: the fact, the cat is lying on the ground Observation: the fact, the cat is lying on the ground Inference logical conclusion based on reasoning Inference logical conclusion based on reasoning The cat is dead. The cat is dead. The cat is asleep. The cat is asleep. Why is the cat asleep? The cat is asleep because he is tired. Why is the cat asleep? The cat is asleep because he is tired. Interpretation observation plus our personal value system Interpretation observation plus our personal value system The cat is so cute! The cat is so cute!

• Scientific Method Scientists use their observations to come up with questions and use the answers to solve problems. Scientists develop and TEST ideas using a systematic, step by step approach called the scientific method. Scientists use their observations to come up with questions and use the answers to solve problems. Scientists develop and TEST ideas using a systematic, step by step approach called the scientific method. In other words, its a way to solve a problem. In other words, its a way to solve a problem.
• Slide 14
• Step 1: Posing Questions Define the focus of the research Define the focus of the research Observe the world around you using all senses to gather information. Observe the world around you using all senses to gather information. Read books or other scientists research Read books or other scientists research Make sure your question is scientific Make sure your question is scientific Can be answered with evidence Can be answered with evidence NOT answered with an opinion NOT answered with an opinion
• Slide 15
• Step 2: Develop a hypothesis A hypothesis is a testable, educated guess to answer your question or is a possible solution to the problem based on your research or observations A hypothesis is a testable, educated guess to answer your question or is a possible solution to the problem based on your research or observations Your prediction, use I think Your prediction, use I think Must be TESTABLE!! Must be TESTABLE!!

• Step 3: Design an Experiment Parts of an experiment: Parts of an experiment: Parameter: something that can be measured Parameter: something that can be measured The parameter being tested is the manipulated variable or independent variable. This is what you are manipulating or changing on purpose The parameter being tested is the manipulated variable or independent variable. This is what you are manipulating or changing on purpose The parameter that you are measuring is called the responding variable or dependent variable. It changes in response to or because of the manipulated variable The parameter that you are measuring is called the responding variable or dependent variable. It changes in response to or because of the manipulated variable
• Slide 17
• Step 3: Design an Experiment (cont) The parameters that dont change are called the controls or constants. Your control group is used for comparison. The parameters that dont change are called the controls or constants. Your control group is used for comparison. The controls DO NOT change so you can be more sure that your manipulated variable CAUSED your responding variable to change, The controls DO NOT change so you can be more sure that your manipulated variable CAUSED your responding variable to change, A controlled experiment is an investigation where only ONE parameter is manipulated at a time. A controlled experiment is an investigation where only ONE parameter is manipulated at a time.

• Step 4: Collecting and Analyze Data Data are the facts figures and other evidence gathered through observations Data are the facts figures and other evidence gathered through observations As you collect the data you got from your experiment, write it down. As you collect the data you got from your experiment, write it down. Organize your data into a chart, table, or graph Organize your data into a chart, table, or graph Use pictures or photos to explain your results Use pictures or photos to explain your results Analyze your data by writing a summary of what happened in your experiment. Analyze your data by writing a summary of what happened in your experiment.
• Slide 19
• Step 5: Draw Conclusions Do the results of your experiment support your hypothesis or not? Do the results of your experiment support your hypothesis or not? A conclusion states whether or not the data supports the hypothesis. A conclusion states whether or not the data supports the hypothesis. Do you need to revise your hypothesis and retest? Do you need to revise your hypothesis and retest?
• Slide 20
• Step 6: Communicate your results to others Share what you found out from your experiment Share what you found out from your experiment Scientists make presentations and write papers so others can repeat their experiments Scientists make presentations and write papers so others can repeat their experiments
• Slide 21
• Step 6: Communicate your results to others (cont.) Scientists use models, theories and laws to explain to people how the natural world works. Scientists use models, theories and laws to explain to people how the natural world works. Model: a picture, diagram or other representation when the real thing is not easy to see Model: a picture, diagram or other representation when the real thing is not easy to see Theory: a conclusion backed up by many scientists with the same results Theory: a conclusion backed up by many scientists with the same results Law: a theory that has been proven over and over again. A rule of nature. Law: a theory that has been proven over and over again. A rule of nature.
