This document discusses an experiment where students learned about basic electricity concepts like circuits, conductors, and insulators. They used batteries, wires, and bulbs to complete circuits and light bulbs. The students found that metals like tin foil and silver conduct electricity, while plastics and paper do not. They then used this knowledge to build more complex circuits with buzzers and switches. Finally, they worked in partners to create an electrical number game where connecting the right answer wire to a question wire would light up a bulb.

1. P3-4 Learn about Electricity

2. The Challenge….
To make the bulb light up

3. ……using the following equipment
1 battery

4. 2 wires

5. 1 bulb
and a bulb holder

6. We had fun finding out how and
where to attach the wires.

8. There was great excitement when
we managed to light the bulb!

12. Everybody was
successful at
lighting their
bulb, but we
found it tricky
keeping the
wires attached.

13. We replaced
the wires with
crocodile clips.
These were
much easier to
connect to the
bulb holder.

14. We also used
2 batteries
with a
battery
holder.

15. We realised
that the clips
had to be
connected to
the metal parts
on the holders.

16. We learned about
conductors
and
insulators.

17. Conductors allow the
electricity to flow all the way
around a circuit
… and so the
bulb will still
light up.

18. Insulators stop the electricity
flowing around the circuit
so then the bulb will not light up.

19. We found out that all
metals were conductors.
A silver necklace
lights up the bulb.

20. Conductors
• tin foil
• keys
• metal rings
• metal spoon

21. We discovered that all
plastics are insulators.
cup
Ruler Lego

22. Insulators
• Wooden Spoon
• Dish Cloth
• Rubber tyre
• Paper

23. Next we learned
how to build
different circuits …

24. using buzzers

25. and we made our
own switches.

26. Our final
challenge was to
make an electrical
number game.

27. We worked
with partners
on this task.
First we thought
of some
challenging sums.

28. We used our
measuring skills to
make the game.

29. The questions and
answers were
connected at the
back with wires.

30. When the correct answer
is matched with a question,
the bulb lights up!
