Natural density

Okay kiddo, imagine you have a small toy box and some toys. You put all the toys in the box and it fits nicely inside. But, what if you try to add more toys to the box? They won't fit, right?

This concept is called density, which means how much stuff can fit in a certain amount of space. Natural density is the same idea, but with things found in nature like trees, water, or rocks.

For example, let's compare a small rock to a big rock. The big rock is heavier because it has more stuff (like minerals) in it than the small rock. But, if you compared their density, the small rock is denser because it weighs more for its size.

Now, let's talk about water. When you fill a cup halfway with water and add ice, the ice floats to the top, right? That's because ice is less dense than water, so it takes up more space for its weight.

Overall, natural density is a way of describing how much stuff can fit in a certain amount of space based on its weight or size. It helps us understand how things in nature interact and why some things float while others sink.
