Conduction, insulator, radiation
ConductionThe movement of heat between objects
that touch each other.
Conduction
Insulator.A material that does not let heat energy or
electricity pass through easily.
insulator
Radiation.The movement of energy through space
waves.
RadiationWaves traveling
through space
Summary
Conduction is the movement of heat between objects that touch each other.
Insulator is a material that does not let heat energy or electricity pass through easily.
Radiation is the movement of energy through space.
Electric Currents and Circuit
Electric CurrentA constant
flow of electrons through a conductor.
Electricity Rules!!!!!!!!!!!!
Without electric circuits our city nights would look like this.
Evaporation is when water evaporates. Condensation is when the evaporated water gathers up
in a cloud
Evaporation and Condensation
Evaporation and Condensation
Water evaporates from the lake. (That’s evaporation.)
Then all that evaporated water gathers up in a cloud. (That’s condensation.)
If you put a cup of
water next to a window on a sunny day, by the end of the day some water will evaporate.
Like this picture, water droplets collect and condensate when you have a cup of cold soda or a cup of water with ice
Evaporation and Condensation
Evaporation is when water is heated and escapes into the atmosphere as a gas.
Condensation is when the water vapor cools and changes back into water droplets.

Force and Friction
Force Force is the
energy power, strength: like if you push a door that causes force
FrictionFriction is the force of two things rubbing
against each other; like if you rub your hands against each other that can cause friction.
This is force because when she hits the ball force occurs.
This is friction because he is rubbing his hands together which causes friction.
Fossil Fuels
Fossil Fuel A fuel that is formed from the decayed remains
of ancient plants and animals.
Dinosaur = Fossil Fuel
Cars use fuel.
Fossil Fuel
Fossil Fuels provide energy to your home and gasoline for your car.
Fossil Fuel
Fossil fuels are a limited resource.
Coal
This fossil fuel is formed by ancient plants rotting and being compressed eventually turning into coal.
PetroleumPetroleum is made from the fossils of
prehistoric creatures being compressed into “black gold”.
Natural GasPlants and animals died and were
eventually buried under the sea floor and formed natural gas.
Global fossil carbon emission by fuel type, 1800-2000 AD.

Gravity is pulling the water toward the shore causing the waves.
Gravity is pulling the woman toward the chair allowing her to sit not float.
Gravity is pulling the water toward the earth to form a lake And a waterfall.
The earth’s gravitational pull keeps the rocket close to the earth.
Gravity is pulling the temple towards the mountain.
Gravity– the pulling of one object toward another.
Heat and Temperature
Heat is the energy of moving particles
Heat is the energy of moving particles.
Temperature is the average speed of the particles in a substance
Heat/Temperature is something burning.
Hydroelectric energy
Hydroelectric energyEnergy made from water
Hydroelectric energy is energy from flowing water
Hydroelectric Energy
Definition Hydroelectric energy is electricity that is
produced by using the energy of water moving through a dam.
How It Helps usIt lights our homes and warms them.
Hydroelectric energy is energy from running water.
Potential and Kinetic Energy
Potential Energy
The energy of an object that is at rest or at a stopping point.
OrStored energy not
yet released.
Potential Energy
Kinetic EnergyThe energy of an
object that is in motion.
Kinetic Energy
Potential and Kinetic EnergyPotential and Kinetic
energy are states of energy that show stored energy and released energy. Potential Energy is energy that is stored or the energy when an object is at rest. Kinetic energy is released energy or energy that is in motion.
kinetic / potential energy
Potential energyPotential energy is an energy that is stored in an object.
Kinetic energyKinetic energy is an energy of motion.
Potential energy picturesPotential energy in this picture is when you go up the roller coaster.
Kinetic energy picturesKinetic energy in this picture is when you go down the roller coaster.
ConclusionPotential energy is un energy that is stored in an object .
Kinetic energy is an energy in motion.
Magnetism
MagnetismA force that pulls magnetic materials
across a distance.
MagnetismA force that pulls magnetic materials

Mass and weight
Mass and Weight
Mass - the amount of matter in a object.
Weight – the measure of the pull of gravity on an object.
Mass
An object will have the same mass on Earth as it will on the Moon.
MassMass is
measured in grams by comparing it to a known measurement.
A balance is used to measure mass.
Mass and Weight
Weight
Weight is the measurement of the pull of gravity on an object.
Weight is measured using a spring scale.
Objects having less mass, weigh less than objects that have a lot of mass, which weigh more.
Weight
An object weighs six times as much on Earth as it does on the Moon.
Mixture- two or more things that can be separated
Solution- two or more things that when mixed together, create a new substance

Mixtures and Solutions
Mixture
A combination of two or more kinds of matter that when mixed, keep their original properties
SolutionA combination of two or more kinds
of matter that when mixed, create a whole new kind of matter
Mixtures and Solutions Mixture – a
combination of two or more kinds of matter that when mixed, keep their original properties
Solution – a combination of two or more kinds of matter that when mixed, create a whole new kind of matter
An object at rest will remain at rest until acted upon.
Newton’s First Law of Motion
An object at rest will stay at rest until acted upon by an
outside force.

Refraction and Reflection
Refraction
The bending of light.
ReflectionThe bouncing back of light rays from a
surface.
How refraction worksThe light rays hit
the water, slowing down the motion of the light rays. The light bends as it hits the water and makes the straw appear differently
How reflection works
The light rays bounce off the mirror
DefinitionsRefraction-the bending of light.Reflection- the bouncing back of light ray
from a surface. If our eyes didn’t refract light the world
would be white.
Solid,Solid, Liquid,Liquid,and GasGas
Solid Solid A solid is a state of matter of which the
substance has a definite shape and a definite volume.
LiquidLiquidA state of matter in which the substance
has a definite volume but takes up the shape of its container.
GasGasA state of matter in which the substance
takes both the shape and the volume of its container.
SummarySolid, liquid and gas are all states of
matter. Solid takes up a definite shape and a definite volume. A liquid takes up a definite volume and takes the shape of the container. A gas takes up both the shape and the volume of the container.
Temperature and Heat
Heat A form of energy produced by the motion of
molecules that make up a substance.
TemperatureA numerical measure of hotness or coldness
on a standard scale.
Heat Did you know that
heat can feed you?
Volume and Density
Volume
The amount of space an object takes up.
Volume
Density
The concentration of matter in an object.
Density
Power generated by harnessing the wind, usually by windmills.
Wind Energy
Wind Energy
Wind energy is a limitless resource.
Wind Generators: provide an alternate source of energy which creates electricity.
