The only thing we will change is whether or not the lights come on. Mail in your hypothesis to us . Watch the data to see what happens to their wheel running. Remember yellow means the lights are on. Also remember, it is okay if you guess wrong.
Scientists guess wrong all the time.
The important thing is to be able to look at the data and understand it. We have started our experiment. We changed the light cycle of hamsters 3,4,5, and 6. Let's look at some of the data. This is an exciting point in our experiment.
