Kids know that flicking switches turns on lights and that radiators get hot when you turn the boiler on, but do they know why? These fun activities that will teach them about energy while keeping them entertained this summer.
We all remember the clock potato experiment from our school days, and this project is essentially the same, but with a fruity twist! In this experiment, kids will learn how to convert chemical energy from the acid in a lemon into electrical energy.
Four lemons (as big and juicy as possible)
Five zinc-galvanised nails
Five sets of alligator clips
How does it work? Find out here.
Dark surfaces absorb more light and heat than lighter surfaces, which reflect more light. This easy experiment shows kids how.
Two identical glasses or jars
Elastic bands or sticky tape
Kids grumpy because their bedrooms are too warm? This easy experiment will show them what happens to air when the temperature rises.
An empty bottle
Pot of hot water (not boiling)
Why does the balloon expand? The molecules in the air inside the bottle are ‘excited’ by the heat and start to move faster and further apart from each other. There is still the same amount of air inside the balloon and bottle, it’s just expanded as it heats up. Warm air takes up more space than cold air, which is why it rises in houses during the summer months.
Most kids have witnessed what happens when you rub a balloon on your head – your hair stands up! This easy experiment illustrates how this static energy is real power and not just a crazy hair dresser substitute.

Learn the nitty gritty of the science behind this here.
You might already have a wind-up toy race car kicking about the house somewhere, but by making one yourself you can demonstrate the difference between potential and kinetic energy from scratch.
How does it work? By twisting the rubber band you’re creating potential energy: energy that has potential to do something in the future, but is not doing anything at the moment. The more twisting applied, the more potential energy is created. Once the pressure is taken off the potential energy (the spool has been put down), the rubber band unwinds, converting the potential energy into kinetic energy, which is the energy found in moving objects.
