Using static electricity to make tissue paper cats ‘pounce’ onto a balloon This is one of a set of free STEM resources developed to support the teaching of the primary national curriculum. They are designed to support the delivery of key topics within maths and science. This resource focuses on making tissue paper cats ‘pounce’ and stick to a balloon through the build-up of static electricity. This activity could be used as a main activity to introduce the concept of static electricity, or as one of several activities within a wider scheme of learning focusing on electricity and its uses. Learners will first cut their tissue paper into small cat shapes. They could use different coloured tissue paper to make different coloured cats for more visual interest. Learners will then blow up and tie their balloons. The balloon should be blown up fully and tied so that no air can escape. If learners struggle to do this, the teacher could complete this step in advance. Alternatively, clips could be provided to seal the balloons. Learners will rub their balloon against their jumper several times to ‘charge’ it with static electricity. Following this, they can hold their balloon just above their tissue paper cat shapes. The cats should ‘pounce’ onto the balloon and stick to it. Why do you think the cats ‘pounce’ and stick to the balloon? How close does the balloon need to be for the cats to pounce? What is causing this to happen? This activity will take approximately 30-50 minutes to complete. Tools/resources required Balloons Tissue paper Scissors The engineering context Engineers use knowledge of science concepts in their everyday work to ensure they produce solutions that are safe, functional and meet the needs of their clients.
