Egg Rolling Physics: Friction and Forces Science Activity for Easter

Egg rolling is a brilliant traditional Easter game that doubles as an exciting introduction to physical science. By testing different surfaces, children begin to understand abstract concepts like friction and gravity in a highly tangible, outdoor setting.

Step-by-Step Setup

1. Boil the Eggs

Hard-boil several eggs before the session (or use small balls or round fruit like oranges if dealing with severe egg allergies). Let them cool completely. Draw a simple smiley face or pattern on each one.

Allergen note: Check pupil allergy records before using real eggs. Keep egg-free alternatives clearly separated for children with egg allergies.

2. Identify the Slopes

Take the children outside and look for different surfaces. Find a grassy mound, a smooth plastic slide, and a tarmac path. Ask: 'Which surface do you think will make the egg roll fastest?'

3. Make Predictions

Before rolling, hold up an egg. Ask the children to predict what will happen. 'Will it bump? Will it roll straight?' Encourage them to use vocabulary like 'fast', 'slow', and 'bumpy'.

4. Ready, Steady, Roll

Let the children take turns rolling the eggs down the different slopes. Use chalk to mark where each egg stops. Compare the distances. 'Look, the egg on the slide went much further!'

5. Discuss the Results

Gather together and discuss why the grass slowed the egg down but the slide didn't. Keep it simple, introducing the idea that bumpy surfaces 'grab' the egg more than smooth, slippery ones.

Classroom Adaptations

Large class?

Create multiple rolling stations outdoors and let children rotate through them in small groups.

Limited resources?

If you cannot use eggs due to allergies or budget, use tennis balls, small balls, or round fruit like oranges.

EAL learners?

Pre-teach key vocabulary like 'fast', 'slow', 'stop', and 'roll' using clear physical actions.

High ability?

Provide measuring tapes and encourage them to record the exact distances the eggs travelled.
