We see light from the sun every day. Light is measured in 'waves' and the light that we can see is only a small portion of the types of light. They are measured in the 'electromagnetic spectrum'. The human eye sees specific areas of the spectrum, but other animals and insects can actually see parts of the spectrum that we can't.

Fun Facts on Heat Energy for kids

Fun Fact 1
The Earth absorbs heat energy which is transferred from the Sun through radiation. The Sun might be millions of kilometres from the Earth but it does control the temperature of our planet.

Fun Fact 2
Our entire universe is made up from tiny particles known as atoms. Kinetic energy is produced when an object moves (when the atoms move). The atoms transfer heat when they move.

Fun Fact 3
Heat Energy is also known as thermal energy. This type of energy is transferred from particle to particle which move quicker with the production of more energy. The quick movement causes bonds to break and heat energy to transfer from one atom to another.

Fun Fact 4
Heat Energy is transferred in three main ways: conduction, convection and radiation.

Fun Fact 5
Definition of radiation: radiation from the Sun travels through electromagnetic waves and produces radiant energy. The Earth absorbs the radiant energy which increased its temperature.

Fun Fact 6
Definition of convection: when Heat Energy is transferred between moving gas or liquid particles.

Fun Fact 7
Definition of conduction: when Heat Energy is transferred between particles which are different in temperature. E.g. if you place a cold and warm object together, heat will pass from the warm object to the cold object through conduction. Conduction will continue until both objects achieve the same temperature.

Fun Fact 8
Example: If you pour cold milk into a bowl of steaming hot porridge, the porridge will cool down. This is because thermal heat is transferred from the hot liquid to the cool liquid.

Fun Fact 9
Example: If you try to pick up something which is hot, such as a metal spoon which has been left in a cup of boiling water, it can be so hot that it burns your fingers - this is because thermal heat is transferred from the metal spoon to your fingers.

Fun Fact 10
Heat energy can transform particles from gas, liquid to solid form. Various occurrences take place when temperatures go up and down. E.g. water will freeze at 0 degrees Celsius and it will boil at 100 degrees Celsius.

Fun Fact 11
Example: It takes a longer amount of time to heat a swimming pool of water than kettle of water. The more liquid there is, the longer it will take to heat.

Fun Fact 12
Heat Energy can transform liquid into gas state. This is known as evaporation or vaporization. Water can evaporate with heat.

Fun Fact 13
Heat Energy can transform gas state to liquid forming condensation - e.g. in the bathroom, vapour can change to liquid.

Fun Fact 14
Heat Energy can transform liquid into a solid when it is reduced. For example, when water reaches freezing point it turns into ice.

Fun Fact 15
Heat Energy causes melting. A solid such as ice will begin the melting process when it starts to absorb heat energy; the ice reacts by changing to a liquid (water).

Can you imagine a world where we don't have electricity...no light switches to turn on, no computers to turn on, no hot water and way more?

Electricity is a big part of our lives, and sometimes we don't even realize it. First, let's take a look at what electricity is.

Then, why not explore our other electricity facts. We have lots of cool information on static electricity and scientists like Michael Faraday and James Clerk Maxwell.

You can even try out our cool static electricity experiment!

Electricity comes from power stations, the wind, the sun, water and seriously, even animal poop! Whoa, who would have thought that animal poop could make electricity?

Electricity is a type of energy that can build up in one place or flow from one place to another.

When electricity gathers in one place it is known as static electricity , which means that it doesn't move and electricity that does move is called current electricity.

Electric current is measured in amperes, called amps for short.

Electric potential energy is measured in volts.

When an electric charge builds up on the surface of an object it makes static electricity. You might have got a small electric shock, which is static electricity.

This happens when an electric charge is quickly cancelled out by an opposite charge.

Ever heard of direct current (DC) or alternating current (AC)? Well there is a difference between the two.

DC electrons move in a single direction, while AC electrons like to shake it up a bit and change from moving backwards to forward all the time.

The electricity you use in your home is AC while DC comes from things like batteries.

What's the world's biggest source of energy? Do you know? Well it actually comes from burning coal.

Coal is burnt in furnaces which heats the water until it becomes steam. This then spins turbines which are attached to generators.

The History of Electricity

The first power plant, opened in New York City in 1882. It was owned by Thomas Edison.

Thomas Edison was certainly a great inventor. He came up with more than 2,000 inventions, which includes almost everything that we need to use electricity in our homes including switches, fuses, sockets and meters.

Wow, that's a lot of inventions.

Benjamin Franklin did a lot of electricity research in the 18th century. He invented the lightning rod amongst many other discoveries.

Lightning rods protect buildings if lightning strikes. It takes the lightning bolt and moves it through a grounded wire.

Interesting Facts about Electricity

Electricity travels at the speed of light. That's more than 186,000 miles per second! Can you even begin to imagine that? That's seriously fast.

A spark of static electricity can measure up to 3,000 volts.

A bolt of lightning can measure up to 3,000,000 volts, and it lasts less than one second!

One single lightning bolt can light up 100 powerful lamps for an entire day, or make lots and lots of toast, in fact a couple of thousand pieces of toast. Don't think you'd be able to eat all that!

A lightning bolt can get really, really hot and reach temperatures of 30,000 °C (54,000 °F). Now that is hot, hot, hot!

A 600 megawatt natural gas plant can power 220,000 homes.

Now this will amaze you. Electric eels can produce strong electric shocks of around 500 volts. They use this to hunt and to protect themselves too. That's pretty cool.

A popular way to create electricity is through something called hydropower. Hydropower is a process where electricity is made by water which spins turbines attached to generators. Pretty neat!

Power Stations - this is a place where electricity is created and sent to our homes and other places where it's needed.

Furnaces - an enclosed structure that makes things very hot.

Turbines - this is a machine that creates continuous power in which a wheel, or something similar, moves round and round by a fast-moving flow of water, steam, gas or air.

Generators - a machine that converts energy into electricity.

Volts - the size of the force that sends electrons through a circuit

Megawatt - this is a unit of power that is equal to 1,000,000 watts and is a measure of how much electricity a power station makes

Fuses - these are safety devices. A fuse is a strip of wire that melts and breaks an electric circuit if it goes over a safe level.

So now you know all about electricity! How about using this information for a school project or telling your friends and parents all the information you know now?

And that's not all! Keep reading for more on this exciting topic!

Whenever something or someone is in motion, it has kinetic energy. When water or wind is moving it has kinetic energy, and people have used wind and water to produce electricity.

So these days we have wind and hydro power we can use in all sorts of ways.

We use electricity from the kinetic energy of wind and water to turn turbines which produce power to run our factories, our machines, our homes and all the electric appliances in our homes.

Without it, we would be living the way our great-great-grandparents did when they cooked on wood stoves, and packed water from the streams.

Where does kinetic energy come from?

All kinetic energy begins as potential energy - things not moving or chemicals waiting to be combined exist as potential energy. Chemicals produce kinetic energy when they are combined.

Have you ever seen a bottle of vinegar and a box of baking soda sitting on the cupboard? These two chemicals have potential energy; when they are combined, they fizz and cause a disturbance; this is kinetic energy.

A parked car with the motor turned off is an example of potential energy. If the ignition is turned on, a spark is created to ignite the gas in the engine and now you have kinetic energy created by the explosion in the engine cylinders.

Another example of potential energy transforming to kinetic energy is a hot air balloon. While it is sitting on the ground with air sitting inside it, the air has potential energy. When that air is heated, it begins to move and expand and causes the balloon to rise. Now the air and the balloon are using kinetic energy.

So, an object that is moving or changing in some way has kinetic energy. It doesn't matter how it is moving or changing. It can be vertically, horizontally, across a distance, in circles, or changing form.

Vertical kinetic energy:

This is a rocket going up in space, a waterfall falling from a height, throwing a ball up in the air, jumping a skipping rope, bouncing a ball up and down.

Horizontal kinetic energy:

Running on a track, shooting an arrow to a target, a pitcher throwing the baseball to the batter, the batter hitting the ball into the field.

Distance kinetic energy:

A car or a bike travelling from point A to point B, the wind blowing leaves across the lawn, a lawnmower travelling over the lawn, you pushing the lawnmower.

Circular kinetic energy - the wheels of the car or bike travelling forward, egg beaters whipping in circles, a tornado with wind travelling in circles.

Some of the examples of kinetic energy that you can think of will actually be examples of a combination of different kinetic energies.

For example, the tornado is horizontal, distance, and circular kinetic energy. Can you think of more examples of combination kinetic energy?

Kinetic Energy Quiz!

It what way do we use wind or water kinetic energy.

1. What kind of kinetic energy does a tornado have?

2. What's the difference between potential and kinetic energy?

3. Give one example of kinetic energy changing something.

4. How does an explosion have kinetic energy?

1. We use wind or water to turn turbines to create electricity.

2. A tornado has vertical, horizontal, distance and circular kinetic energy.

3. An object that does not move has potential energy and once it moves, it has kinetic energy.

4. Wind blowing a leaf across the lawn makes the leaf travel and changes its position.

5. The kinetic energy of an explosion can change how something looks or destroy it completely.
