What's Wrong Lulu?





My ice pop turned into a puddle!
Oh.... you mean it melted?



IT WHAT?!


It melted! The heat from the sun made your ice pop change states of matter!


Woah! What's matter?


There are 3 states of matter. Liquids, solids, and gases!

Think of your ice pop, it started as a solid. The heat from the sun caused it to melt into a liquid


How can I make it solid again?


Changes in temperature are typically what cause a change in the state of matter.


To change a solid to a liquid you have to heat it up. To change a liquid to a solid you need to freeze it!
