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.

Thank you for your attention!

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.

Wind Energy Wind energy is an important resource

because it provides us with electricity for our homes and businesses.
