Recap

What is energy?

Energy from the sun

Types of energy

Transferring energy

The conservation of energy

Potential energy

Energy calculations

What is energy?

The ability to do work.

The ability to do work

Unit: Joule (J)

Name what work is being done in every picture.

Also, come up with three examples of energy being used in everyday life.

What did we learn about

the Sun?

What did we learn about

the Sun?

• The sun is the original source of energy for everything in our solar system.
• All energy in food can be traced back to plants.
• Plants use photosynthesis to convert the Sun's energy into their growth.

Energy types

Exercise

• Go over paragraph 2.3.

• Write down the nine types of energy.

• Match the demonstration materials on the table with the correct energy type.

• Come up with one other example for each energy type.

• Motion: skateboard
  

Electric: power source

Radiant energy: lamp

Sound energy: Speaker

Thermal energy: matches

Gravitational potential energy: Book

Elastic energy: Spring

Chemical energy: Battery

Energy in fuel

(if we have time)

Bio fuel

Fuel produced from biomass, such as plant waste and vegetable oils.

Fossil fuel

Coal

Oil

Gas

Coal

Formed from dead plant matter which were buried under layers of mud for millions of years.

Oil and gas

Formed from Dead Sea creatures. They were buried under sand at the bottom of the sea. Over millions of years, they turned into gas and oil.
