A hypothesis is a prediction on what you think will happen. For experiments on insects being attracted to light or heat, a hypothesis could be that insects are attracted to light over heat.
most experiments on animals are harmless even if they look bad. animals feel less pain then us and are very oblivious. insects can not feel pain at all. and there brain is too small to know whats happening
Insects and Lobsters
Insects have exoskeletons.
Insects are not meat.

1. Create a hypothesis regarding why the insects seem to suddenly appear. 2. Create an experiment to test that hypothesis. 3. Collect and analyze the results of the experiment. 4. Finally, draw conclusions whether the results support your hypothesis. For example, a hypothesis might be that insects appear in flour, fruit, and cornmeal because they hatch from eggs, which were deposited when the observer wasn't looking. To test that hypothesis, a sample experiment may be to place flour, fruit, or cornmeal in two separate jars. In one jar, put a lid on it. Leave the other jar open. For a week or so, look at the jars daily and write down whether you see insects. If you do, jot that down. These are your results. After a week or so, you can look at the results and compare them. If insects appear in both jars, the experiment did not support the hypothesis. (NOTE: that doesn't mean the hypothesis is wrong; only that that experiment did not support it.) If insects appear only in the closed jar, then you could conclude that your hypothesis was supported by the experiment. Again, that doesn't mean your hypothesis is right; only that it was supported by the experiment. Based on your conclusions, you can make a new hypothesis, which could further refine the cause of the insects.

The food that a fish or insect eats gives them the ultimate source of energy. Fish and insects can be carnivores or herbivores.
George Washington Carver would experiment on insects, peanuts, yams, soybeans, mushrooms, and all sorts of other plants.
Some people think that seeds are more "moral" to experiment with than small animals and insects.
Common house spiders need to eat insects to live!

An experiment once showed an ant lived without air for eight days (The Junio Book of Insects, p.85)

Actually the weight of the peach made it move so it wasn't so much the insects wanted to roll downhill like they did. After the ride to the ocean they decided to go to NYC and the adventures began.
