Stage 2: Testing Ideas

Do mealworms prefer black or white surfaces?


Apparatus and materials used:
- Spoons
- Mealworms
- Black and white paper


Hypothesis: They would towards the black surface.
Reason: Our initial idea was that they would move towards the black surface as we thought that they preferred dark area.

Conclusion:  The mealworms preferred the white surface as compared to the black.
Reason: This could be due to the fact that white absorbs less heat, and they prefer cooler places.
(Also, they moved off the black and white paper and onto the marble table. The possible reasons could be that they either wanted to escape desperately, or they wanted to go on the cool marble table.)      


Stage 3: Preliminary Experiment

Do the mealworms react to light?

Hypothesis: The mealworms would move away from the light.

Reason: Our initial idea was that they would move away from the light as we thought that they preferred a dark area.

Conclusion: They are more sluggish in the dark, and more active when light is introduced. When light is introduced, they would move rapidly away from the light.
This therefore shows that they prefer the dark as they seem more comfortable within it. Therefore, in their natural habitat, they would move away from the light source to presumably find a darker spot to rest in.
