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.
Students understand the processes of scientific investigation and design, conduct, communicate about, and evaluate such investigations. Students know and understand the characteristics and structure of living things, the processes of life and how living things interact with each other and their environment. Students know and understand interrelationships among science, technology, and human activity and how they can affect the world. Students understand that science involves a particular way of knowing and understand common connections among scientific disciplines. The Insects kit contains an assessment section in the teacher's guide.
