Pupils needing extra support: 

Could use the Knowledge organiser: Science – Sensitive bodies to help them answer the questions in the Attention grabber; could use the Activity: Touch test results table: support version to record their results; could only test with either the pen or the cotton bud, only filling in the final column of the results table.

Pupils working at greater depth:

Should explain why it is important that people can feel things; should explain why fingertips are more sensitive than the back of the arms (for example, our fingertips get used more in daily life, help us to pick up things and work out if a temperature is safe).
