Egg Strength Scientific Investigation

Year 6 Science Investigation Exploring adaptation and strength Working scientifically with fair testing

WALT - We Are Learning To

Design and carry out a fair scientific enquiry Investigate the strength of eggs Evaluate the trustworthiness of our methods Use scientific language to explain results Make predictions for further tests

Why Don't Eggs Break Easily?

Think about when a hen sits on her eggs What makes an egg strong despite seeming fragile? How might the shape help protect what's inside?

Success Criteria

I can explain why eggs are strong and how shape helps I can work with my group to set up a fair test I can collect accurate measurements and record clearly I can evaluate how trustworthy our results are I can suggest improvements for further enquiries

Planning Our Investigation

Work in groups of 4 Choose which part of the egg to test Decide how to keep the egg steady Plan what to measure and how Think about what could make the test unfair

Fair Testing Variables

Conducting the Experiment

Add weights progressively until the egg breaks Record all measurements carefully Take photos or sketch your setup Note any observations about how the egg breaks Consider what might affect your results

Reflecting on Our Investigation

{"left":"What variables did we control well?\nHow precise were our measurements?\nWhat could we improve next time?","right":"How trustworthy are our results?\nWhat further questions could we investigate?\nDid egg shape affect the results?"}
