What Happened?

The Worm Bowl requires observation and prediction. The contestants observe their mealworms and try to choose some characteristics that they believe will make them leave the circle the fastest. When they select a mealworm, they are predicting which will go the fastest to the outer part of the circle.

Of course, mealworms are living things. They can be very active one moment and calm the next. It can be very hard to predict the winner, which is what makes the Worm Bowl so exciting!

Fun Fact

Although mealworms are long, all 3 pairs of legs are located on the thorax, very close to the head.

After a long day of competition, your worms might want to relax in a worm condo. Find out how to build one on the next page.
