The world is full of animals. To keep track of animals scientist sort animals into groups.
Scientists sort animals into several groups by what they look like or how they are built.
Touch the back of your neck. Do you feel bumps. This is part of your backbone.
Your backbone goes from your hips all the way up to you head. Not all animals have a backbone.
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.
Examples of amphibians are frogs, toads, newts and salamanders.
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.
Reptiles have backbones. They have scales and are cold-blooded. They need sunlight to stay warm. Most reptiles lay eggs.
Examples of reptiles are snakes, lizards, crocodiles, turtles and tortoises.
In your science notebook add reptiles to your list of animals with backbones. Write a few examples of reptiles in your science notebook.
Mammals have backbones. Mammals have hair or fur. They give birth to live young. Mammals can give milk to their young.
Examples of mammals are chimpanzees, cats, cows, horses, koalas, pigs, sheep, whales and lions.
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.
Examples of birds: penguins, parrots, geese, robin and hawks.
In your science notebook add birds to your list of animals with backbones. Write a few examples of birds in your science notebook..
Fish have backbones. Fish live in water and they breathe with body parts called gills. Fish have fins that help them swim.
In your science notebook add fish to your list of animals with backbones. Write a few examples of fish in your science notebook.
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.
