We started our vertebrates and invertebrates unit with Ranger Jen. Last week we worked in groups to learn more about vertebrates. Then, we presented our information to the class.
Here is what we learned.
Mammals have backbones. They also need to be cared by their mother or father. They were born live, not born in eggs. There are about 4,000 different kinds of mammals. Their prey are birds and seals, but that’s all we know of their prey for now. Mammals are warm-blooded. Mammals can live in many different environments including land, oceans, and freshwater lakes. Dolphins and whales have hair along with other mammals. People belong in the mammal group.
Facts About Fish!
Fish have gills for all of their lives. Fish have been on earth for 500 million years. Fish have over 200 species all over the ocean water. Fish come from small to big sizes. Fish eat algae which is green slime goo. Fish eat coral and some fish eat other fish. Fish are cold blooded. Salmon migrate every year to breed and lay eggs. Fish have a good sense of taste. Some fish live in salt water, like halibut and cod. This is our report on fish. Thank you for joining us!

Reptiles have lungs, long tongues, and scales. They are cold blooded. There’s over 8,000 reptiles and, they use varieties of defense methods. Most reptiles have legs, some reptiles can regrow body parts, and all reptiles lay eggs. Most reptiles don’t tolerate cold weather, and the first reptile to exist was 320 millions of years ago. Some kids asked when was the first reptile existed and we said, “320 million years ago.” Other kids asked if they were vertebrates and we said, “yes.”

Birds are vertebrates, that means they have a backbone. Birds are warm blooded so they don’t change temperature when the weather changes. They have very light feathers so they can fly. They lay eggs, and they do not give birth without an egg. They have a four chambered heart. They breath through lungs. Some have webbed feet, that means they spend a lot of their time in the water. Some examples are penguins, ducks, and geese.

Baby amphibians are born swimming. A few species of frogs give birth to live young. These are born as miniatures adults. Frogs don’t need to drink water because they absorb it through their skin. There are over 5,000 species of frogs. Frogs lay eggs that have a jelly like stuff around them.

While our friends presented, we took notes on the vertebrates they researched. We are getting to be really great note-takers this year!
