Sorting Animals by How They Look and Move

with Lumi

Lumi stands in a sunny meadow beside a pond, holding up a big sorting mat with three picture boxes labeled fur, feathers, and scales. A fluffy rabbit hops nearby, a blue jay lands on a branch, and a goldfish glides through the pond while Lumi points excitedly at each animal.

Identify at least three animal body coverings: fur, feathers, and scales.
Sort animals into groups based on one shared body covering.
Explain why two animals belong in the same group using one feature they share.

Key terms

body covering: The outer layer that protects an animal's body.
fur: Soft hair that covers animals like dogs and cats.
feathers: Light, soft coverings that grow on birds.
scales: Small, hard pieces that cover fish and snakes.

Sorting By Body Covering

Animals can be sorted into groups by looking at their body covering, which is the outer layer that covers and protects their bodies. The three coverings in this lesson are fur, feathers, and scales. When you sort, the trick is to pick just one feature to look at, like body covering, instead of trying to notice everything at once. Picking one feature makes sorting clear and easy, just like sorting your toys by color.

Fur And Feathers

Some animals are covered in fur, which is soft hair. Dogs and cats both have fur, so they belong in the same fur group. Other animals are covered in feathers. Birds like chickens, eagles, and parrots all have feathers. Many birds use their feathers to fly, but not all do; penguins have feathers and use their wings to swim instead of fly. All feathered animals still go in the feathers group together.

Scales On Fish And Snakes

Scales are small, hard pieces that cover an animal's body like tiny tiles or armor. A fish is covered in scales, and so is a snake, even though a fish swims and a snake slithers on land. Because they share the same body covering, fish and snakes belong in the same scales group. This shows that very different-looking animals can still be grouped together when they share one important feature.

Worked examples

Why do a dog and a cat go in the same group?

A dog has soft hair covering its body, which is fur.
A cat also has soft hair covering its body, which is fur.
Since they share the same body covering, they go in the fur group.

Answer: They both have fur, so they belong in the fur group.

Can a fish and a snake share a group?

A fish is covered in small hard scales.
A snake is also covered in scales, even though it lives on land.
Sharing the same body covering means they can be grouped together.

Answer: Yes, both have scales, so they go in the scales group.

Hi! I am Lumi, and today we are going to sort animals — just like sorting your toys into bins! Look at a dog. It has fur. Fur is soft hair that covers its body. A cat has fur too. We can put them in the SAME group! Now look at a bird. It has feathers. Feathers cover a bird's body. Many birds use their feathers to fly! A chicken has feathers. A penguin has feathers too — but penguins use their wings to swim instead of fly. They all go in the feathers group! A fish has scales. Scales are tiny, hard pieces that cover a fish like little tiles. A snake also has scales. They go in the scales group together. Here is a hint: when you sort, pick ONE thing to look at — like body covering. Don't try to look at everything at once!

Activity

Drag each animal into the bin that matches its body covering.

Practice

Decide which group a feathered parrot belongs in and explain why.

Name the body covering that a goldfish and a snake share.

Common mistakes to avoid

Animals that move the same go togetherMoving is not a body covering; you must sort by fur, feathers, or scales, not by how an animal moves.
All birds with feathers can flyAll birds have feathers, but not all fly; penguins have feathers and use their wings to swim instead.

Check your understanding

A bird and a chicken both have feathers. What group do they belong in?

A fish and a snake both have scales. How are they the SAME?

Mia wants to put a dog and a bird in the same group. What is wrong with that idea?

Recap

Animals can be sorted by body covering, the outer layer that protects them. Fur covers dogs and cats, feathers cover birds, and scales cover fish and snakes. When sorting, pick just one feature to look at so the groups stay clear.

Reflect

What body covering does your favorite animal have, and why?
