OBSERVATION
Static Electricity
Conductors and Insulators
Circuits
Magnetism and magnets
HYPOTHESISThese are our questions
● Can playdough conduct electricity?
● Can a balloon attract aluminium foil?
● Can an electric current produce magnetism?
● Can a lemon generate electricity?
Experimentation● We created circuits using salt playdough,
lemons and potatoes.
● We checked that magnetism moves the arrow on a compass.
● We created an electro-magnetic circuit that attracted paper clips.
● With a magnet we checked that iron chips form the shape of the magnet .
CONCLUSION
If we rub a balloon against wool, it attracts small pieces of aluminium foil.
We now know that...
We have checked the hypothesis with different experiments
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
