Animals Week 7 Directions 1. Prepare your desk for science. Take out your homework. Glue it into your notebook on page 17. 2. Use voice level 2 (conversation) to discuss this question: What is complete metamorphosis? What is incomplete metamorphosis? If you have OLD signed tests to turn in, please put them on the desk up front.
Targets & Warm Up Targets: Students will compare and contrast animal changes in… – Embryonic development – Complete metamorphosis – Incomplete metamorphosis Warm Up: How are complete and incomplete metamorphosis similar? How are they different?
Similarities between complete and incomplete metamorphosis Both Types of metamorphosis Common in insects Egg and adult stage Changes in structure Adult looks different from the young Happen after the first stage
Differences between complete and incomplete metamorphosis Complete 4 stages Pupa and larva Young looks very different from the adult Incomplete 3 stages Nymph Young looks similar to the adult except for the wings
Embryonic Development vs. Incomplete Metamorphosis
Similarities between embryonic development and incomplete metamorphosis Both During the life cycle Changes in structure Animal grows Happen over time
Differences between embryonic development and incomplete metamorphosis Embryonic Development Changes before birth Many different structures develop Ends at the first stage Common in animals that hatch from eggs or develop in the mother Incomplete Metamorphosis Changes after birth Wings develop Starts at the first stage Common in animals that hatch from eggs (mostly insects)
