Microwave Miracle Patrick believes fish that eat food exposed to microwaves will become smarter and would be able to swim through a maze faster. He decides to perform an experiment by placing fish food in a microwave for 20 seconds. He has the fish swim through a maze and records the time it takes for each one to make it to the end. He feeds the special food to 10 fish and gives the regular food to 10 others. After 1 week, he has the fish swim through the maze again and records the times for each.

What was the independent variable? 4. What were some of the constants? 5. What hypothesis might be stated before doing this experiment? 6.
