We use lemons and strips of zinc and copper to make a battery.

We compare the properties of iron mixed with water and with oil, and a ferrofluid.

We use two magnets and a set of scales to examine magnetic field and strength.

We create a simple electromagnet by coiling wire around a nail and passing current through it.

We investigate the effect that unbalanced charge has on polar molecules.

We use a Van de Graaff generator to investigate static electricity.
