CONCLUSION

OBSERVATION We have been observing Static Electricity

Conductors and Insulators

Circuits

Magnetism and magnets

HYPOTHESIS These are our questions ●

Can playdough conduct electricity?

●

●

Can a balloon attract aluminium foil?

Can a lemon generate electricity?

●

Can an electric current produce magnetism?

Experimentation ●

We created circuits using salt playdough, lemons and potatoes. ●

●

With a magnet we checked that iron chips form the shape of the magnet .

We checked that magnetism moves the arrow on a compass.

●

We created an electro-magnetic circuit that attracted paper clips.

CONCLUSION We have checked the hypothesis with different experiments We now know that... 

If we rub a balloon against wool, it attracts small pieces of aluminium foil.



Circuit elements: a battery, a conductive wire, a switch and a receptor (which can be a light bulb).



Lemons, potatoes and salt playdough are conductors



Electricity and magnetism are related: this becomes electromagnetism
