1. Energy
Transformations

2. An energy type can be transformed
into another type of energy.
Electrical
Energy
Light
Energy
This is called
Energy Transformation.

3. The energy starts as one type (the energy it USES)
Light Energy
(Electromagnetic)
Electrical Energy
It ends as a different type
(the energy it GIVES)

4. Examples:
Rubbing your hands together USES
mechanical energy
and GIVES thermal energy--
your hands start feeling warm!

5. Eating food USES chemical energy
and GIVES mechanical energy--
you now have energy to move!

6. A fan USES electrical energy
and GIVES mechanical energy--
the blades are now moving!

7. An electromagnet USES electrical energy
and GIVES magnetic energy--
the metal has become magnetic!

8. Can you identify the transformation?
You will need to be able to
tell what energy is USED
and what energy it GIVES

9. What energy does it USE?
It uses ELECTRICAL energy,
because you have to plug it in.

10. What energy does it GIVE?
It gives off microwaves which are
ELECTROMAGNETIC energy.

11. What energy does it USE?
It uses lightwaves from the sun,
which is ELECTROMAGNETIC.

12. What energy does it GIVE?
It gives off electricity which is
ELECTRICAL energy.

13. What energy does it USE?
It uses CHEMICAL energy
from the flame.

14. What energy does it GIVE?
It gives off THERMAL (heat) and
ELECTROMAGNETIC (light)

15. What energy does it USE?
It uses ELECTRICAL energy
because it gets plugged in.

16. What energy does it GIVE?
It gives THERMAL energy
because it heats the bread.

17. What energy does it USE?
It uses CHEMICAL and THERMAL
energy from burning gasoline.

18. What energy does it GIVE?
It gives MECHANICAL and KINETIC
energy because the parts move to make
the car drive around.

19. What energy does it USE?
It uses POTENTIAL energy
from being up high before a fall.

20. What energy does it GIVE?
It gives KINETIC energy
because it moves fast downhill.

21. What energy does an
atomic bomb USE?
It uses POTENTIAL and NUCLEAR
energy from the atoms that will be split.

22. What energy does an
atomic bomb GIVE?
It gives ELECTROMAGNETIC energy
as radiation, and THERMAL heat.
