Many different products have already been created based on plant and animal traits. For example:

In 1948, a Swiss chemist studied cockleburs that stuck to his dog's coat. He copied them and developed self-hooking straps, commonly known as Velcro.

Cockleburs have sticky hooks

These shoes have sticky hooks like cockleburs. The straps stick together.

An inventor saw cockleburs stick to an animal.

The inventor

had an idea to make

sticky hooks.

People get ideas for inventions from the world around them. They use those ideas to make things.

Many good ideas come from observing plants and animals. People copy the shape or function of plant and animal parts to make products we can use.

Coral polyps are tiny animals that live in shallow ocean waters. Some kinds of coral polyps build coral reefs.

Coral reefs change the ocean environment. They provide homes, food, and safety for many different ocean animals.

Many animals have feet. However, not all animal feet are the same. Animal feet are built in many different ways.

How an animal's feet are built determines what the animal can do. An animal's feet are built in a way that helps the animal survive.
