amplitude

animal cell

atom
word root: atomos = cannot be divided up
A very small, basic part of matter.

ATP

balanced

biodiversity

biotic

biotic factors

boundary

carbon cycle

carbon dioxide

cell

cellular respiration

Celsius (°C)
A way of measuring temperature, using the metric system.  Water freezes at 0°C, and boils at 100°C.

centimeter (cm)
word roots: centi = hundred, meter = measurement
A 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.

chemical change

chemical compound

chemical equation

chemical formula

chemical properties

chemical reaction

chlorophyll

chloroplast

claim
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.

coefficient

commensalism

competition

concentration

conservation of matter

consumer

convection

convection currents

convergent boundary

core

crust

current

decomposer

divergent boundary

earthquake

ecosystem

ecosystem services

electromagnetic spectrum

element

energy

energy being used

erosion

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

Fahrenheit (°F)
One way of measuring temperature.  Water freezes at 32°F, and boils at 212°F.

food chain

food web

forces

fossil fuels

gas
Something that change both its shape and volume.  One of the states of matter. 

glucose

gram (g)
word root: gramma = a small weight
A metric unit used for measuring mass.  It is about as heavy as a dime.
 

growth

heat

hydrocarbon

igneous rock

inner core

kilogram (kg)
word roots: kilo = thousand,  gramma= small weight
A metric unit used for measuring larger masses. It is about as heavy as a textbook.  There are 1000 grams in a kilogram.

kilometer (km)
word roots: kilo = thousand, meter = measurement
A 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.

kinetic energy

lava

light energy

limiting resources

liquid
Something that can change its shape but keeps its volume.  One of the states of matter. 

liter (L)
A metric unit used for measuring amounts of liquid or gas. It is about as much liquid as two small water bottles can hold.

magma

mantle

mass
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).

matter
word roots: mater = mother, materia = wood or substance
Something that takes up space and has mass.  Matter makes up everything in the universe.

metamorphic rock

meter (m)
word root: meter = measure
A metric unit used for measuring distances.  It is about as long as a doorway is wide.

methane

milligram (mg)
word roots: milli = tiny thousands,  gramma= small weight
A 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.

milliliter (mL)
word roots: milli = tiny thousands
A 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.

millimeter (mm)
word roots: milli = tiny thousands, meter = measurement
A 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.

mitochondria

modification

molecule
One or more atoms stuck together.  The atoms can be the same type or different types.

mutualism

niche

nitrogen cycle

observation
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.
related words: observe, observing

organism

outer core

oxygen

parasitism

particle
word root: particula = little part
 A tiny bit of matter.

periodic table

petroleum

phosphorous cycle

photosynthesis

physical change

physical properties

plant cell

plate

plate boundary

plate tectonics

population

potential energy

predator

prediction
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".
related words: predict

prey

producer

products

proposal

purification

reactants

recycling

renewable

reproduction

resource constraints

resources

rock cycle

scarcity

science
word root: scientia = know
Studying the natural world around us through observing and experimenting.

sediment

sedimentary rock

solid
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.

stored energy

subscript

symbiotic

temperature
How much heat something has.  It is usually measured using the Fahrenheit scale (°F) or the Centigrade scale (°C).

thermal energy
Heat.  If enough is removed, gases become liquids, and liquids become solid.  If enough is added, solids become liquids, and liquids become gases.

transform boundary

trophic levels

visible light

volcano

volume
How much space something takes up.

water

wavelength

weathering
