Part 1: Designing the Experiment My Question: ______________________________________ _______________________________________ Part A: Things I could change or vary: Part B: Things I could measure or observe: 2

Identifying Variables I will change: I will measure or observe: Place one item from Part A here Place one item from Part B here I will not change these things: (These things will control my experiment): Place remaining items from Part A here. I will not measure or observe: Place remaining items from Part B here. 3

Asking a Testable Question (Refining my beginning question) When I change _________________________________: What happens to ________________________________? What I will change What I will measure or observe Write the question that will guide your experiment: __________________________________________________________________________________________________________________________________________ Predictions (List 3 possible outcomes: Increase, Decrease, or No Affect.) Based upon my question, I predict: 1. 2. 3. Choose a prediction and generate a hypothesis statement: Hypothesis: If_______________________________________ then_____________________________________ because___________________________________. 4

The Procedure (Others should be able to follow the way you set up your controlled test.) Procedures (List exactly what you did in each step of your experiment. ) Materials List (Include quantities.) _________ ________________________ ________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________ ________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________ Controls (What conditions should be kept the same?) __________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________ 5

What I will change or vary (independent variable): Number of trials I will conduct or amount of samples: ______ The data I will collect by measuring or observing (dependent variable): What I will measure or observe How I will collect the data: _____________________________________________ How I will record the data (for example: table, chart, picture): ____________________________________________________________________________________________ 6

Part 2: Conduct the Experiment Data Collection: What I will change (independent variable) What I will measure or observe (dependent variable) Record your Data: This chart is intended as an example to help get you started. You may design your own chart to fit your experiment. Results (Use metric measurements.) Item(s) Tested Trials   1   2  3  4  5  Avg. 7

Y axis X axis Graphing your Results Which type of graph is best- line graph or bar graph? ______________ Graphs should reflect the trials and the average of the trials. What I measured or observed (dependent variable) Y axis What I changed (independent variable) What I will change (manipulated variable) X axis (Note: Both axes will need to be labeled and the appropriate scale marked) 8

Title of Graph: __________________________   Y-axis: ______________________________________ X-axis: ______________________________________ 9

Explain your Results 1. Looking at your graph, describe your results. _________________________________________________________________________________________________________________________________________________________________________________________________________________________________________ 2. Conclusion: Was your hypothesis supported or not supported? Explain. ____________________________________________________________________________________________________________________________________________________________________________________________________________________________________________ 3. Compare your initial predictions and the actual results from your experiment. ____________________________________________________________________________________________________________________________________________________________________________________________________________________________________________ 4. Explain real world uses relating to the results of your experiment. ____________________________________________________________________________________________________________________________________________________________________________________________________________________________________________ What are some questions that you have for further investigation? _________________________________________________________________________________________________________________________________________________________________________________ 10
