What are particles in grade 5?

Answer 1

Particles are the tiny building blocks that make up everything around us, including solids, liquids, and gases. They are so small that we can't see them with our eyes; instead, we can think of them as tiny specks or dots. In solids, particles are close together and vibrate in place, while in liquids, they are more spread out and can move around each other. In gases, particles are far apart and move freely, which is why gases can fill up any space they are in.
