Non-Renewable
Not able to be renewed quickly/takes a long time
Step 1 of coal
Millions of years ago, plants and animals died
Step 2 of Coal
Buried under water and dirt, usually around swamps
Step 3 of coal
Heat and Pressure turns it into coal
Renewable Resources
Can be replenished easily
Solar
from the Sun
Geothermal
Energy from Earth’s heat
Wind Energy
Energy from the Wind
Biomass
Burning organic matter
Water/Hydroelectric energy
Energy from the flow of water
Matter
has mass and volume / cannot be created or destroyed
mass
the amount of matter in an object
uses triple beam balance, pan balance
volume
the amount of space an object takes up
uses beaker, graduated cylinder, syringe, ruler, measuring tape, tape measure
temperature
measures the energy of motion of particles
aka kinetic energy
more energy = higher temp
less energy = lower temp
density
able to float or sink
less dense - float
more dense- sink
liquid
has definite volume but no definite shape
gas
no definite volume or shape
solid
definite volume and definite shape
solute
substance that dissolves
larger solutes dissolve slower
solvent
substance it dissolves in
hot solvents dissolve faster
cold dissolved slower
does water go through chemical change
no
what makes chemical changes happen faster
increasing temperature
mixture
when two or more objects or substances are combined
solution
a type of mixture that has the same composition throughout/ CANNOT SEE ITS PARTS
heterogeneous mixture
a mixture that can be differentiated
can be seperated by:
shape/color/texture/size/density/using sieve/magnetism/filtration/evaporating
