Activity Introduction

snappy-science-heroQuick summary: Students light up the room by rubbing a balloon on their hair and using the static energy to light up a light bulb.

mod logoThese Snappy Science resources have been created to boost science education in primary schools across Australia. Each lesson is designed to support teachers with the scientific knowledge, ideas and resources to stimulate a sense of wonder and curiosity in their students. Many of the big issues that Australian society will face in the future are around technology, energy, resources and climate change. All of these require students to engage with science – but most of all to enjoy science!

Science at Home: These Snappy Science resources can also be used to engage families in fun science and learning for life. You can download a student friendly version of this activity here and you can also check out the Snappy Science Digital Library.

General capabilities: Critical and creative thinking.

Australian Curriculum content description: This activity is relevant to Science Inquiry Skills across all primary year levels of the Australian Curriculum.

snappy-science-heroBrief summary:

Students light up the room by rubbing a balloon on their hair and using the static energy to light up a light bulb.

Students can use the Predict, Observe, Explain table on the Student Worksheet to describe and reflect upon this experiment.

You will need:

  • Dark room
  • Fluorescent light bulb (energy saving bulb or tube)
  • Balloon
  • Full head of hair

What to do:

Step 1. Blow up a balloon and tie off the end.

Step 2. Rub the balloon vigorously against the hair on your head.

Step 3. Go into a dark room.

Step 4. Touch the balloon against the two metal electrode prongs on the bottom of the fluorescent light bulb.

Step 5. Watch what happens when the static electricity discharges from the surface of the balloon into the fluorescent light bulb.

Step 6. Repeat rubbing the balloon to add more static electricity to the surface of the balloon. If careful, the balloon can be held against the light bulb as it is rubbed against hair. As the balloon surface builds up enough sta
