First graders last week about the three states of matter in experiments involving solids, liquids and gas.
Here are the facts:
- Solid matter is composed of tightly packed particles. A solid will retain its shape; the particles are not free to move around.
- Liquid matter is made of more loosely packed particles. It will take the shape of its container. Particles can move about within a liquid, but they are packed densely enough that volume is maintained.
- Gaseous matter is composed of particles packed so loosely that it has neither a defined shape nor a defined volume. A gas can be compressed.
Look around the classroom. Everything, from the clothes you are wearing to the air you breath is matter. Matter is very important. Matter makes up everything including living things like plants and people. It also makes non-living things such as tables and chairs. Things as big as an elephant or as tiny as a grain of sand on a beach are matter.
