This week we move from invertebrates to vertebrate animals.
What is the difference?
Some of the things we focus on in general this week are fish, amphibians, and reptiles
How are fish adapted to live in water? What advantages do amphibians have over fish? How have reptiles evolved to life on land?
As with invertebrates, contract 9 focuses on a specific vertebrate species in the three phyla.

Fish have gills to breath, scales to keep H2O in and out of body, most have swim bladder=air chamber to stay afloat.sharks don't.
How the people make the stuff we recycle get to be reused?
How can we use recycled materials?
Vertebrate animals aren't as diverse as invertebrates. They only make up 50% of all animals which is totally crazy and I don't really understand how that is possiable.
All animals with a internal skeleton made of bone are called vertebrates.
i like learning about things are are more like us: have more than one cell and have backbones but i do like learning about things that live in the water too
scared for the test!:P
Fish have scales and fins, amphibians live in water at first then they go to land because they have mucas that protects, and reptiles have hard scales and lay eggs.
