Understanding Matter
Matter: is anything that has mass and takes up space.
Look at the picture and name some matters:
- Everything you can see is matter. However, somethings you cannot see also are matter, Such as the Air because it has mass and take place.
Understanding Matter
Things that not matter:
- oLight
- oSound
- oEnergy
- oForces
To decide whether something is matter, ask yourself:
DOES IT HAS MASS AND TAKES PLACE???
Atoms
Atom: is a small particles that is a building block of matter.
Building blocks are used to construct different objects, for example:
Different arrangement make up many types of objects
So, different arrangement of atoms will make up many types of ______
