Grade 7 Week 9: First Vertebrates

We also begin our final section before the exam. We begin looking at tthe first vertebrates: fish, amphibians, and reptiles.

What special characteristics do fish have for survival under water?
How are amphibians adapted to life in water and on land?
Why do they have to go back to water?How are reptiles able to survive completly out of water?
How does it make a shell around its egg?
How does it have scaly skin?
This week's contract asks you to again choose one unique species of the selected Chordate phyla. This friday you will share the characteristics of your vertebrate.
