What are chemical reactions?

A chemical reaction is when stuff you know changes into something new, just like when your favorite snack turns into a different snack right in front of you!

Imagine you have two types of building blocks: one red and one blue. When they meet, they click together to make purple blocks, which are completely different from the ones you started with! That’s what happens during a chemical reaction. The old stuff (like the red and blue blocks) becomes new stuff (the purple block).

Think about when your mom bakes cookies. She starts with flour, sugar, butter, and eggs, all separate things. But when she mixes them together and heats them up in the oven, they turn into soft, warm cookies! The ingredients didn’t just melt or mix, they changed to become something totally new.

So next time you see a change happening around you, like bread rising or fruit turning from sour to sweet, remember: a chemical reaction might be working its magic (but not the magical kind, just the real, everyday kind!).
