Have you ever had a static shock from a shopping trolley or an escalator? The shock is because of static electricity which can cause materials to attract or repel each other.
A fun way to demonstrate static electricity is by making jumping frogs.
Paper, cut into shapes. We used sugar paper, but tissue paper would also work brilliantly.
Woolly jumper or hair
Cut up your different types of paper into frog shapes ( or anything else you want to make jump )
Blow up your balloon, and rub it on your jumper or hair. Hold above the frogs, and watch them jump up.
Why it works?
Rubbing the balloon on your jumper or hair, charges it with static electricity, this attracts the frogs making them jump up to the balloon. They will stick until the charge wears off.
Does it still work if you use normal paper and cardboard?
Can you time how long the Frogs stay stuck for?
If you rub the balloon on your hair for longer do the frogs stick for longer?
Do smaller frogs stick for longer than bigger ones?
Other Static Electricity ideas
Inspiration Laboratories also has a very cool ghost static electricity activity.
