down on your desk.2. Use voice level 2 (conversation) to discuss this

question: • What happens during embryonic

development? Share examples with your tablemates.

Targets & Warm Up

Targets:Students will define complete and incomplete metamorphosis.Students will compare and contrast complete and incomplete metamorphosis.

Warm Up: What is metamorphosis? Do all animals go through metamorphosis? Does it look the same in all animals?

Embryonic DevelopmentAnimals go through embryonic development, where they develop structures that they might need as an adult.

Do all animals develop all structures that they will need as an adult when they are in the embryo?

Question

embryo?

Metamorphosis• The process that living things go through

as they change form in different stages of their life cycles.

Question

Complete vs. Incomplete Metamorphosis

Complete Metamorphosis Incomplete Metamorphosis

Complete Metamorphosis

• 4 stages of growth• Egg, larva, pupa, adult (for insects)• Larva looks very different from the adult

Incomplete Metamorphosis

• 3 stages of growth• Egg, nymph, adult• Nymph looks like the adult without wings

Vocabulary

Nymph: a stage in an insect life cycle between egg and adult that looks like an adult but has no wings

Larva: a young animal that has a different shape than the adult

Pupa: the stage in the insect life cycle between larva and adult
