things around it.
 Energy can be mechanical , light , sound ,
thermal electrical , chemical or nuclear

3.  Can be:
 Renewable such as water, wind, sun, biomass or waves
and tidies
 Non Renewable such as fuels or uranium and plutonium

4.  Our bodies transform chemical energy from
food into mechanical energy for movement.

5. Electricity is a form of energy :
• We can transport it easy through power lines.
• It can transform into others types of energy, like
the light energy of a light bulb.

6. Static electricity : it occurs when an object
accumulate electrical charge.
It can be :
 Neutral
 Positively charge
 Negatively charge

7. • Conducting materials : electrical charges moves
easily through them.
• Insulating materials : electrical charges cannot
move through them.

8. Electrical current is the movement of
electrical charges through a conducting
material.

14. Producing and using electricity cause
problems to the environment.
 Changes in landscapes
 Depletion
 Pollution

15. Use public transport
Turn off heaters Practise the 3 R`s

16. Magnetism is the ability of materials to
atract metals.

17. All magnets have
two parts, their
north poles (N)
and their south
poles (S)
