Why  Do Things Float?

A lot of things float and a lot sink, but  there's still a lot to learn about why things float.

This is what I learnt about things floating.

Things float because of their weight  and volume. Volume is how much space it takes up. If something is heavier than the water the water will rise and the object will sink and If it's lighter than the water it will float. Some examples of things that float are coins, rocks, cellphones, cars, bobby pins, tin cans, marbles and rings. Things that float are paper, straw, pencils, plastic bottles, tennis balls, wood and flip flops.

How things float

Things float because of something called density. Everything around us is made of tiny molecules. In some objects molecules are jammed together, and in others the are loosely packed together. This is actually  what density means. The objects that are jammed together have a higher density, and the more loosely packed objects aren't as dense.

Now I hope you know what floating is.
