Matter

Matter is anything that has mass and volume

This fish has mass and volume so it is matter

Not Matter

Anything that does not have mass or volume, like heat, light, etc.

The light bulb is giving off light. Light has no mass or volume.

Pure Substance

A pure substance is something that is made out of the same kind of particles.

The diamond in the ring is a pure substance because it is only made out of carbon particles.

Element

An element is a pure substance that can not be broken down into simpler substances and are made out of the same molecules

This aluminum foil Is only made out of aluminum molecules.

Compounds

A compound is a pure substance that is made out of more than one element.

This sugar is a compound because it is made out of carbon, hydrogen, and oxygen

Mixtures

A mixture is 2 or more substances mixed together but not chemically bonded

This piece of paper is a mixture. It has paper and ink.

Heterogeneous Mixtures

A heterogeneous mixture is a mixture where you can tell it is not just one substance.

The wall is a heterogeneous mixture of concrete, rock and soil.

Homogeneous Mixtures

A homogeneous mixture is a mixture that looks like it is one substance

This grape juice is a mixture of grape juice concentrate and water, but it looks like one substance.

Mass

Mass is the amount of matter something has.

The chips’ mass is 12 grams

Volume

Volume is how much space something takes up.

This bottle of water’s volume is 200 ml.

Suspension

A suspension is a substance with another substance in it but not dissolved in it.

This ranch is a suspension because it has herbs suspended in it.

Emulsion

An emulsion is a suspension with super tiny little balls of a substance in another, but they don’t mix and are spread out evenly.

This mayonnaise is an emulsion because the vegetable oil is suspended in the vinegar.

Mechanical Mixtures

A mechanical mixture is a mixture where you can easily tell the different parts.

This pile of pens and pencils is a mechanical mixture because you can see the individual pens and pencils.

Reversible Change

A reversible change is a change that you can reverse so it seems like it never happened.

the girl swings up but she can just swing back down so it is a reversible change.

Non-Reversible Change

A non-reversible change is a change that you can never change back

If you cook something, you can’t make it raw again

Physical Change

A physical change is changing something’s shape, not what it is made of

The footprint is changing the water’s shape to a footprint shape

Physical Change Part 2

Another example of a physical change is crushing a snack so it changes into a powder shape.

Chemical Change

A chemical change changes what the substance is made of.

The moisture in the air causes a chemical change with the metal and creates iron oxide which is rust.

Another Chemical Change

Another chemical change is photosynthesis. Photosynthesis is when plants take carbon dioxide, sunlight, and nutrients from the soil to make sugar and oxygen.
