Nature's Gifts & Our Cool Creations!

Hi, Super Scientist! Have you ever helped bake yummy cookies? 🍪 Some ingredients, like an egg from a chicken or water from a faucet, come from nature. But the cookie itself? We mixed everything together and baked it in an oven to make something new!

The world around us is just like that cookie kitchen. Some things are found just as they are in nature, and some things are made by people. Let's explore!

Found in Nature! 🌳

Things that come straight from our amazing planet are called natural materials. We find them in forests, in the ground, and in the water. They are gifts from the Earth!

Wood comes from trees. It feels hard and can have bumpy bark.
Rocks 🪨 are found on the ground. They can be smooth or rough, big or small.
Cotton comes from a fluffy plant. It feels super soft!

Made by People! 🔧

When people take natural materials and change them, they create human-made materials. These are things you won't find growing on a tree!

Paper 📄 is made from wood, but it's thin, flat, and easy to fold.
Plastic is used for toys and bottles. It can be smooth, shiny, and colorful.
Fabric for our clothes can be made from cotton, but it's woven together to be strong and cozy.

⭐ Key Takeaway! ⭐

If it grows, comes from an animal, or is found in the ground... it's probably NATURAL!

If people mixed, heated, or built it in a factory... it's probably HUMAN-MADE!

Let's Be Material Detectives!

Time to investigate! Look around your room. Can you find one natural thing, like a wooden block? Can you find one human-made thing, like a plastic toy car? You did it! You can tell the difference between nature's gifts and our own cool creations. Keep exploring, little scientist!
