They come to know firsthand the life sequences of a number of insects. In each activity an insect is introduced, and students observe structures and behaviors, discuss their findings, and ask questions. Students observe life cycles of insects and compare the stages of metamorphosis exhibited by each species. The insects provided to the teacher include mealworms, milkweed bugs, butterfly larvae, and crickets. Needs of insects include air, food, water, and space.
Insects have structures.
The life cycle of the beetle goes from egg, to larva, to pupa, to adult, which produces eggs. Butterflies and moths have very similar life cycles. Insects' larvae have structures in common. Some adult insects need food. Some insects spend part of their life cycle in water.
