I will take 5 people. For three days, I will give them two glasses of milk to drink before they eat dinner. I will serve the same food for those three days and they will eat at the same time every day. After three days of drinking milk, I will then have the people eat for three days without drinking milk before they eat dinner (again, same food, same time). I will measure how much food they eat in the three days that they drink milk and the three days that they don’t drink milk and compare my results.” </p><p>What is the independent variable? ______</p><p>What is the dependent variable? ______</p><p>What are the constants? 1. ______</p><p>2. ______</p><p>3. ______</p><p>What is the control? ______</p>
