When we do research, we are looking at relationships between variables. Variables are measurable items, characteristics, etc…that we want to know about. For example:
How does education impact income? The variables here are education and income.
Education is an Independent Variable…we want to know what causes an effect in our Dependent Variable, which would be income.
A hypothesis is a statement of a relationship between two or more variables. We are going to state a hypothesis when we state what we think we are going to find with the results.
Watch this interactive video from 24/7 science to learn about identifying independent and dependent variables. (There are 3 parts to this video. Start by watching the video below. You will be prompted in the video to click a link on the top-right of the video after a couple of minutes. Click the link, watch the Mythbusters clip and then you will see another button to click that will take you to part 2 of the 24/7 science video. You will do this a few times to look at a few different myth busters clips)
When you are done, submit a paragraph discussing which experiment was your favorite and tell me what the independent and dependent variables were for that experiment. What was the Mythbusters hypothesis for the experiment you chose?
