This lesson
Recap
2.3 Energy types
Working independently
Slide 2 - Diapositive
Learning goals
Make a list of the nine types of energy
Give examples for each type of energy
Name the two categories of energy (kinetic and potential energy)
Explain what is meant by energy transfer
Slide 3 - Diapositive
Recap
Exercise
Step 1)
Discuss with your neighbour what we covered about energy so far
Step 2)
Go through the book
Slide 4 - Diapositive
Energy is
the ability to do work
The unit of energy is
Joule (J)
All work requires a source of energy
Slide 5 - Diapositive
The sun
is the source of all energy in the solar system
Our energy source is food
— The energy in food comes from sunlight, which gets converted into chemical energy through photosynthesis.
Slide 6 - Diapositive
Fossil fuels
— are made of animals and plants that passed away millions of years ago, which got buried under many layers of earth.
Green energy
