What is expanding?

What is expanding? Think of it like blowing up a balloon, everything inside gets bigger.

Imagine you have a bag of jellybeans. You put them in a small bowl, and they all fit nicely. Now, you pour the same number of jellybeans into a larger bowl. The jellybeans themselves didn’t get bigger, but the space around them did. That’s what expanding is like: the space between things gets bigger, even if the things themselves don’t.

When something expands, it's like when you put your favorite snack in the microwave. The heat makes the air inside the snack move and stretch out, that’s why the bag might puff up or even pop!

You can also think of expanding like a growing garden. If you plant seeds in a tiny pot, they grow slowly. But if you move them to a bigger garden, there's more room for the plants to spread out and get stronger.

Expanding isn’t magic, it’s just things getting more space to be in! What is expanding? Think of it like blowing up a balloon, everything inside gets bigger.
