Grade 6 Science Review part 2

matter

anything that has mass and takes up space

mass

is a property that is measured in grams, by using a TBB

physical property

color, shape, texture, order, and form are examples

kinetic energy

energy in motion

potential energy

energy that is stored

insulator

materials that do not allow heat to transfer easily

conductor

materials that allow heat to transfer easily

density

mass /volume

fog

a stratus cloud near the ground

radiation

transfer of energy by waves

conduction

heat transfer by touch, particle to particle

convection

heat transfer that involves fluids; creates currents

technology

designed by humans to make life easier, solves a problems, or meets a need

first step in the engineering process

identifying a problrem

Moh's Hardness Scale

used to test a minerals hardness

pollution

the introduction of harmful waste products, chemicals, and substances into the environment

conservation

using resources with a goal of reducing damage to the environment

ionosphere

home to the Northern Lights

tropophere

lowest layer of Earth's atmosphere, humans live here, weather occurs here

condensation

when moisture condenses and becomes a liquid

precipitation

any form of water that falls to the ground; rain, sleet, snow, etc.

hurricanes

form over tropical oceans

ozone

where most of the ultraviolet radiation from the sun is absorbed.

wind chill factor

the increased cooling that wind can cause

exosphere

the layer of the atmosphere that merges with outer space

igneous rocks

formed by molten material cooling

sedimentary rocks

formed by weathering, erosion, deposition, compaction, and cementation

metamorphic rocks

formed by heat and pressure

elements

substances that cannot be broken down chemically into other substances

kilogram

the SI unit for mass

Celsius or Kelvin

the SI unit for temperature

meter

the SI unit for length

atom

the basic building block for all molecules

Graduated cylinder

tool used to measure the volume of a liquid

ruler

tool used to measure length

triple beam balance

tool used to measure mass

100 degrees celsius

the boiling point of water
