What are chemicals?

Chemicals are like tiny building blocks that make everything around you work.

Imagine you have a box full of different kinds of LEGO bricks, some red, some blue, some big, some small. Each brick is a chemical, and when you put them together, they can build something cool, like a car or a castle. Just like LEGO bricks can be used to make many things, chemicals are used to make everything from toys to food to your favorite drink.

Chemicals are all around you, in the air, in water, and even inside your body! When you eat an apple, it's made of chemicals that help you grow. When you play with chalk, you're using a chemical that leaves marks on the board. Some chemicals are used to make things like soap or candy.

People mix different chemicals together to create new things. For example, mixing baking powder and water makes bubbles, just like when you blow into a bottle with some soda inside! It's like having a secret recipe for making cool stuff happen every day.
