Particles
Science: KS3, topic 2.1.1
Particles
Everything in the universe is made of tiny ‘particles’.
Particles
- We imagine these particles to be like lots of small balls.
- You cannot see them with your eyes, but scientists have lots of ways to detect them.
- The particles that make up everything in the universe can be arranged in lots of different ways.
- How the particles are arranged determine whether something is a solid, liquid or gas.
Test yourself on Particles
What state are particles which are not touching and are always moving most likely to be in?
In which state of matter are particles always touching but able to move past each other?
Why can liquid particles move past each other but solid particles cannot move at all?
Select the correct statement in each pair.
Name the two states of matter that have particles able to move.
