Matter is anything that has mass and takes up space. It can be found all around us in different forms and substances. Understanding how matter is structured and how it behaves helps explain everything from why ice melts to how metal rusts. This concept includes knowledge about atoms, elements, compounds, mixtures, solutions, and physical and chemical properties.
1. States of Matter and Changes
Matter exists in different states, also called phases, which depend on the arrangement and energy of particles. The most commonly taught states in elementary school are solid, liquid, and gas.
Characteristics of the three main states:
- Solids
Have a definite shape and definite volume.
Particles are tightly packed and vibrate in place.
Do not flow easily.
Examples: ice cube, rock, wooden block.
