Mealworms and Surface Texture
Medium
Do mealworms travel farther on smooth surfaces or rough ones? You test several different materials:
- sandpaper
- cloth
- paper
- wood
- aluminum foil
Place a mealworm in the center of each surface and time it for two minutes. Each time it changes direction mark a dot. After two minutes connect the dots and measure the total distance. Test ten mealworms on each surface and calculate the average.
Comparing the averages shows which textures help mealworms move the farthest. The results also hint at how a mealworm's body grips certain surfaces.
Hypothesis
The hypothesis is that mealworms will move differently on different surfaces.
Science Concepts Learned
Animal Locomotion
The surface under a mealworm's body changes how far it travels. You test several materials — sandpaper, cloth, paper, wood, and aluminum foil — by placing a mealworm in the center of each and timing it for two minutes. Each time it changes direction, mark a dot; after two minutes, connect the dots and measure the total distance. Test ten mealworms on each surface, then calculate the average. Comparing the averages shows which textures help mealworms move the farthest and hints at how a mealworm's body grips certain surfaces.
Method & Materials
You will test each mealworm on each surface for two minutes, mark the center of the test material with a small "x", place one mealworm on the mark and start timing, and record the total distance the mealworm traveled.
You will need 12 inch by 14 inch pieces of different textured surface materials, 10-12 mealworms per student group, different colored nail polishes, a clock or watch with a second hand, and permanent markers.

See what’s includedResults
The results showed that different surfaces affect the distance mealworms travel in two minutes. The texture of the surface had an impact on the distance the mealworms traveled, with some surfaces allowing the mealworms to travel farther than others.
Why do this project?
This science project is interesting and unique because it allows students to observe the movement of mealworms on different surfaces and measure the distance they travel.
Also Consider
Experiment variations to consider include testing the mealworms on different surfaces with different temperatures and testing the mealworms on different surfaces with different levels of humidity.
