Remember the definition of hypothesis from our earlier section of work -a hypothesis is a tentative explanation that can be tested, and is usually based on previous observations. For example: My hypothesis is that my kids sleep better when I take them on a walk of at least 15 minutes long each day. reishe takes in more suugar 6. Design an experiment to test YOUR hypothesis.
