We made this change to learn more about the Clock. See if you can follow the data . The data are exciting right now. We are actually running two experiments at one time. It is okay to do two experiments at once as long as you are certain you have only one independent variable in each one.
Independent variable is constant darkness .
We certainly can see the biological clock influencing behavior in these two experiments . We are about to wrap up this set of experiments. Let's see what we have learned from our data over the last few months .
