3. Matter is anything that has mass and volume
This fish has mass and volume so it is matter
4. 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.
5. 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.
6. 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.
7. 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
8. 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.
9. 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.
10. 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.
11. Mass is the amount of matter something has.
The chips’ mass is 12 grams
12. Volume is how much space something takes
up.
This bottle of water’s volume is 200 ml.
13. 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.
14. 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.
15. 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.
16. 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.
17. A non-reversible change is a change that you
can never change back
If you cook something, you can’t make it raw
again
18. 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
19. Another example of a physical change is
crushing a snack so it changes into a powder
shape.
20. 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.
21. Another chemical change is photosynthesis. Photosynthesis
is when plants take carbon dioxide, sunlight, and nutrients
from the soil to make sugar and oxygen.
