Science 8Th Grade Finals

Front 1

Intrusive Igneous Rock

Back 1

This rock is when magma harden beneath Earth's surface.

Front 2

Extrusive Igneous rock

Back 2

This rock forms from cooling lava

Front 3

Transform Boundary

Back 3

Are where two plates are sliding past one another which makes earthquakes.

Front 4

Divergent Boundary

Back 4

New crust is created as one or more plates pull away from each other.

Front 5

Convergent Boundary

Back 5

Crust is destroyed and recycled back into the interior of the Earth as one plate dives under another. There are three types, oceanic-oceanic, oceanic-continental, continental-continental.

Front 6

Scientific Models

Back 6

Are used in science because we can't bring earth systems into the classroom.

Front 7

Radiation

Back 7

The transfer of energy through air.

Front 8

Convection

Back 8

The transfer of heat by movements of a heated fluid.

Front 9

Conduction

Back 9

The transfer of heat by direct contact of particles of matter.

Front 10

Experiment

Back 10

A procedure to test a hypothesis.

Front 11

Front 13

Solution

Back 13

The state of being dissolved.

Front 14

Pure Substance

Back 14

A sample of matter, either an element or a compound, that consists of only one component with definite physical and chemical properties and a definite composition.

Front 15

Mixture

Back 15

A substance made by mixing other substances together.

Front 16

Matter

Back 16

the substance or substances of which any physical object consists or is composed.

Front 17

Back 18

a mixture is a material system made up by two or more different substance which are (mixed) together but are not combined.

Front 19

Compound

Back 19

A thing that is composed of two or more separate elements; a mixture.

Front 20

Independent Variable

Back 20

are the variables in an experiment that are to be held constant.

Front 22

Dependant Variable

Back 22

what you measure in the experiment and what is affected during the experiment

Front 23

Back 23

When you have an experiment, it is the data you can label a numerical value to.

Front 24

Qualitative Data

Back 24

Observable Data

Front 25

Scientific Prediction

Back 25

A prediction or forecast is a statement about the way things will happen in the future, often but not always based on experience

Front 26

Scientific Theory

Back 26

a theory that explains scientific observations.

Front 27

Meniscus

Back 27

the convex or concave upper surface of a column of liquid.

Front 28

Liquid

Back 28

composed of molecules that move freely among themselves but do not tend to separate like those of gases; neither gaseous nor solid

Front 29

Gas

Back 29
