Experiment 10: Mealworms on Caffeine
Hypothesis: We hypothesized that the mealworms would die when they ingested the caffeine and this is why we saved this experiment for the end.
Materials:
-Carrot
-Coffee
Procedures:
1. Soak a small piece of carrot in coffee for 10 minutes.
2. Place the carrot in the shoebox, close the lid, and check back every 5 minutes for 15 minutes.
Observations:
5 minutes later: Most of the mealworms were climbing the wall and none of them were burrowed in the oats or bran.
5 minutes later: Most of the mealworms were still climbing the walls.
5 minutes later: Some of the mealworms were in the oats and bran; most were lying on the ground.
Conclusions: The mealworms did not die. The caffeine seemed to have an energizing effect on the mealworms and then they crashed.
Independent Variables: Size of the carrot, caffeine marinating time, observation time.
Dependent Variables: Behaviour of the mealworms.
