Sorting Animals Lesson 55. The world is full of animals. To keep track of animals scientist sort animals into groups. How do we sort animals?. Scientists sort animals into several groups by what they look like or how they are built. Some animals have backbones and some do not.
Scientist sort animals with backbones into more groups. This helps scientist study and understand more animals.
Amphibians have backbones. Almost all amphibians begin their life in water. They often have smooth and wet skin. This helps them live on both land and water.
In your science notebook let’s make a chart. Write backbones and write amphibians. I’ll show you in my journal. Then you can list examples of amphibians in your science notebook.
In your science notebook add reptiles to your list of animals with backbones. Write a few examples of reptiles in your science notebook.
In your science notebook add mammals to your list of animals with backbones. Write a few examples of mammals in your science notebook.
Birds have backbones. They are the only animals with feathers. They have two wings and two legs. Not all birds can fly. A penguin is a bird that can not fly.
Today we learned we can sort animals into groups. We learned about animals with backbones. We also learned ways to sort animals with backbones. We learned we can sort them into five groups: amphibians, reptiles, mammals, birds and fish.
