Presentation to teach electricity to 4th- 5th -6th graders.

1. ELECTRICITY AND
MAGNETISM

2. ELECTRICITY IN NATURE ELECTRICITY AT HOME

3. WHERE CAN YOU FIND
ELECTRICITY?

4. PLUG SOCKET
SWITCH

5. Electricity wires have
copper inside
BULBS

6. WHAT IS ELECTRICITY?
Matter is made of very small particles called atoms.
An atom has a balance (equal charge) of protons
and electrons (positive and negative charge)

7. Because of a source of energy on the atom the electrons
move from one atom to another and that produces
ELECTRICITY.

8. Thales was the first to notice static
electricity around 600 BC. In 600
B.C.
Thales of Miletus writes about amber becoming charged
by rubbing – he was describing what we now call static
electricity.

9. STATIC ELECTRICITY: some
materials like plastic loose electrons
easily

10. Rub an inflated balloon or a comb
on your head or a wool sweater
and..

11. Stick the balloon
to a wall...
Bring the balloon close to one end of
the popsicle stick, and watch it rotate
on the spoon!

12. -Unlike charges attract each other.
-Like charges repel each other.

13. ENERGY SOURCES: we need
energy to generate electricity
1- Renewable means that never run-out: sun, wind, water, ..

14. 2-Non renewable sources are more contaminating: oil,
gas, batteries.. and will run out in the future.

16. SAFETY ADVICE
.
-Never put your fingers or any other objects in
electrical sockets

17. -Never use electrical devices near water or touch
switches with wet hands.

18. -Always hold the plug by the plastic part.

19. -Don't use a device with damaged wires.
