The Benefits of Exercise

• Did you ever wonder whether being "in shape" actually makes exercise easier for you? Test it out. Have your friends run laps around the playground during recess for several weeks, and take their pulses after each round of laps. Over the course of the experiment, as they become more fit, do their pulse rates stay lower? If so, you have shown that exercising often actually makes the exercise easier in the long run.
  
  

Low-fat and Low-cal Foods

• Can people really tell the difference between low calorie products and the regular version? Between fat-free products and the regular version? Test it out. Have your friends close their eyes and taste two of the same type of food--one healthier than the other. Ask them to identify the food, and record their answers. How many people got it right? If you publicize the results of this experiment, you may convince your friends that the healthier versions of foods taste just as good as the "regular" versions.
  
  

Breakfast - Most Important Meal of the Day?

• Come up with a fun quiz to give your friends or family. It might be memorizing tough vocabulary words, doing challenging math problems or reading a dense paragraph and asking questions about it. Then give this test to many different people--half of them before breakfast and half of them after breakfast. Record how well each person does. Find out if the people who had already eaten breakfast do better than the people who did not.
