Animals Directions Week 7 Prepare your desk for science. Put your signed summative assessment face down on your desk. 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?
Table of Contents Date Title Page Metamorphosis 16, 17 Once you are finished with the Table of Contents, go to page 16 & 17 and add the title and date to the top of the page.
Which of these young and adult pairs is not like the others? 1 2 3
Embryonic Development Animals 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 What is it called when animals change form after they have come out of the embryo?
Metamorphosis The process that living things go through as they change form in different stages of their life cycles.
Question “But… the baby chick looks different from the hen, so it must go through metamorphosis.” Is this statement correct or incorrect?

Complete vs. 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
