5th Grade Matter

Matter is anything that has mass and takes up space.

The three states of matter are solid, liquid, and gas.

A solid is a state of matter where particles are closely packed together and vibrate in place.

A liquid is a state of matter where particles are close together but can move past one another.

A gas is a state of matter where particles are far apart and move freely.

When ice melts, it changes from a solid to a liquid, which is a physical change.

A physical change is a change that affects one or more physical properties of a substance without changing its chemical composition.

A chemical change is a change that results in the formation of new chemical substances.

Protons are positively charged particles found in the nucleus of an atom.

Neutrons are neutral particles found in the nucleus of an atom.
