What are physical and chemical processes?

Building blocks change shape or become new building blocks, that’s what physical and chemical processes are!

When Blocks Just Change Shape

Imagine you have a big block of chocolate. If you break it into little pieces, it's still chocolate, just smaller. That’s like a physical process. It changes how something looks or feels, but not what it really is.

When Blocks Turn Into New Blocks

Now imagine you melt that chocolate and mix it with butter to make brownies. The chocolate isn’t just broken up, it becomes part of something new. That's a chemical process. It changes what something really is, like turning ingredients into a tasty treat!

So, physical processes are like rearranging toys in a box, still the same toys. Chemical processes are like making new toys from old ones, completely different toys! Building blocks change shape or become new building blocks, that’s what physical and chemical processes are!
