Science 9 Experimental Design Term 2 Project
Getting StartedName______
From the list below, or from other topics that interest you, pick two topics that you may be able to find a connection between, or in other words two topics where one may affect the other somehow. We will call these our “two-topic combinations.” For example from the list below I might be interested in gravity and perhaps how it affects springs. Thus, my two-topic combination is “Gravity and Springs.” Determine whether materials related to these topics would be easily available to you, or if the cost would be too much. Keep in mind that you will be eventually designing an experiment in which something will be measured, so try to choose measurable topics. Find a total of 3 different “two-topic combinations” that interest you and then write them in the spaces below.

The first three parts of the scientific method are 1) Problem (Ask a Question, 2) Hypothesis (Formulate a Hypothesis), and 3) Experiment (Design and Conduct an Experiment). For this project, we will follow accepted experimental design:
“Problem” or“Ask a Question” becomes the title of your project. Your title will be in this form:
The Effect of (independent variable) on (dependent variable)
Remember that the independent variable is controlled by the experimenter (“the one that I change”) and the dependent variable changes as a result of changing the independent variable (it depends on the other).
“Hypothesis” or“Formulate a Hypothesis” becomes an If…Then…statement.:
If something is done to the independent variable, then the dependent variable will do this.
Be specific in how you will change the independent variable (increase, decrease, etc.). Be specific in how you believe the dependent variable will be affected. If you are not sure, at this point you may need to do some research.
“Experiment” or “Design and Conduct an Experiment” includes the materials needed, a step-by-step detailed procedure, a detailed list of variables that must not change during your experiment, what the control in your experiment will be, and the data table you will fill in when collecting your data. You will take multiple trials at multiple levels (conditions).
Which of 1,2, or 3 above do you think you will be able to turn into an experiment? Go back and mark it and start planning your experiment below.
