ELECTRICITY EXPERIMENTS
Construct a circuit
Materials/apparatus
*coated wire
*battery
*wirestrippers
*bulb
Step 1.Cut two pieces of wire. Carefully strip away the plastic
than twist the bare strands of wire together.
Step 2.Firmly fix one end of each wire to each side of the battery. Make sure the wire is touching the sides of the battery.
Step 3.Make one wire touch the base of the bulb and the other one touch the side. This forms a circuit and the bulb lights up.
Jump with Electricity
Apparatus/Materials
-scissors
-balloon
-pen
-balloon pumper
-thin paper
Step 1.Draw some small people on the paper.
Step 2.Carefully cut them out. Make as many people as you like.
Step 3.Place all your paper people on a table.
Step 4.Pump up the balloon until it is quite big.Then tie a not in its neck so no air escapes.
Step 5.Rub the balloon on some woollen clothes.
Step 6.Hold the balloon about 10cm above the people.Then the people start jumping up and down.
Probe for Electricity
Apparatus/materials
*Two 1.5v batteries
*Sequins
*Scissors
*Bulb-holder
*3.5v bulb
*wire strippers
*coated wire
*Three pipe cleaners
*Glue
*screwdriver
*aluminium foil
*Tape
Step 1.Tape the top of one battery firmly to the base of the other,with a foil square between them.
Step 2.Cut lengths of wire 25,12 and 8cm long.Tape the 25cm wire to one battery.
Step 3.Connect the 12cm and 8cm wires to the holder.Tape the 8cm wire to the other battery.
Step 4. Tape the bulb-holder to the batteries.Fix paper around the batteries and wires to make a bug.
Step 5.Touch the foil balls on the bug's feelers to different kinds of materials.The bulb lights up if electricity can pass through the material.
