Investigate - Baby Animals - Episode 201



Go ahead, open a can of worms!
Investigate how mealworms respond to different stimuli, such as touch, sound, light or scents. (Ask your teacher for help getting a supply of mealworms.) How do they react to light? Put a worm on a table, shine a light on it, and see if it turns to or away from the light. Or place a smelly piece of food next to a worm and see if it moves toward the food or away from it. Devise similar tests and track the worms' responses. After the testing is completed, watch the mealworm metamorphose into a beetle. What differences do you notice about how the mealworm and the beetle respond to those stimuli? Can you explain why they would be different?
