## Activity Introduction

Quick summary: Students race soft drink cans with using static electricity to move the cans across a table.

These 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.

## Worksheets

### Brief summary:

Students race soft drink cans with using static electricity to move the cans across a table.

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

### You will need:

• Several empty soft drink cans
• Inflated balloon
• Table

### What to do:

Step 1. Place the can on its side on a table.

Step 2. Take the balloon and rub it against your hair in a fast motion.

Step 3. Bring the balloon close to the can but don’t let it touch the can. The can will begin to roll towards the balloon on its own.

Step 4. Ask students to repeat the activity and hold a race between cans.

### How does it work?

By rubbing the balloon through your hair, you create an electric charge that builds up on the surface of the balloon. This is called static electricity (non-moving electricity). Static electricity contains electrons, which have the power to pull small light objects towards it like soft drink cans.

### Student Worksheet

In this experiment you will be using your hair to race soft drink cans.
