word root: atomos = cannot be divided
A very small, basic part of matter.
A way of measuring temperature, using the metric system. Water freezes at
0°C, and boils at 100°C.
word roots: centi
= hundred, meter = measurement
metric unit used for measuring smaller distances. It is about as long as your pinky finger is wide.
There are 100 centimeters in a meter.
Saying that something is true without
providing evidence or proof. A good experiment should be able to test a claim to see if it is true or not.

word root: evident = obvious
or information used to prove if something is true or not. Scientists use observations to collect evidence during an

temperature. Water freezes at 32°F, and boils at 212°F.
Something that change both its shape and volume. One of the states of matter.
word root: gramma
= a small weight
A metric unit used for measuring mass. It is about as heavy as a dime.
word roots: kilo = thousand, gramma= small weightA
metric unit used for measuring larger masses. It is about as heavy as a textbook. There are
1000 grams in a kilogram.
word roots: kilo = thousand, meter = measurementA
metric unit used for measuring larger distances. It is about as long as the distance you can walk in 15 minutes,
or 3 times around a PE running track. There are 1000 meters in a kilometer.
Something that can change its shape but keeps its volume. One of the states
A metric unit used for measuring amounts
of liquid or gas. It is about as much liquid as two small water bottles can hold.
The amount of stuff (matter) that something
has. We can think of this as weight (which measures how much something can be pulled on by Earth's gravity).
word roots: mater = mother, materia
= wood or substance
Something that takes up space and has mass. Matter makes up everything in the universe.
word root: meter = measure
metric unit used for measuring distances. It is about as long as a doorway is wide.
word roots: milli = tiny thousands, gramma= small weightA
metric unit used for measuring tiny masses. It is about as heavy as a single grain of sand. There are
1000 milligrams in a gram.
word roots: milli =
tiny thousandsA metric unit used for measuring tiny volumes of
liquid or gas. It is about as much liquid as a single drop of water. There are
1000 milliliters in a liter.
word roots: milli = tiny thousands, meter = measurementA metric unit used for measuring tiny distances. It is about as long
as a dime is thick or a pencil mark is wide. There are 10 millimeters in a centimeter, and 1000 millimeters
in a meter.
One or more atoms stuck together.
The atoms can be the same type or different types.
word roots: ob = toward,
serva = look at
Looking at or watching something carefully to get information. Usually done with sight,
but other senses could be used as well. Scientists write down and record this information.
word root: particula = little
A tiny bit of matter.
word roots: pre = before,
dict = say
What a scientist thinks is going to happen, based upon observations. This is written down
before the experiment actually starts. It is usually in a sentence with the structure "if - then - because".
word root: scientia = know
the natural world around us through observing and experimenting.
Something that keeps its shape and
volume. One of the states of matter.
state of matter
One of the ways (forms)
in which matter can exist. Usually, this means that something is solid, liquid, or gas.
How much heat something has.
It is usually measured using the Fahrenheit scale (°F) or the Centigrade scale (°C).
Heat. If enough is
removed, gases become liquids, and liquids become solid. If enough is added, solids become liquids, and liquids become
How much space something takes
