Science KS2: How do muscles and bones work?

Using a skeleton, elastic bands and rubber gloves, Zoe demonstrates to a group of children how our muscles and bones allow our body to move.

We hear about how some animals have exoskeletons, and graphics on a tablet demonstrate the bone structures holding the children up.

The number of bones in the body and the calcium that forms them are also covered.

Zoe explains about joints, and how muscles work in pairs, contracting to pull parts of our bodies in different directions.

This short film is from the BBC series, Amazing Me.

Teacher Notes

You could get a skeleton model and connect rubber bands to the bones in order to demonstrate how one muscle contracts, while the other expands, and how they work together to move the bones.

Pupils could create a poster with a list and pictures of animals with an exoskeleton and others who have their skeletons on the inside of their body.

They could discuss and note on the poster what are the advantages and disadvantage of having your skeleton on the outside and the advantage and disadvantage of having your bones inside your body.

Curriculum Notes

This short film will be relevant for teaching the topic of the human body at KS2 in England, Wales and Northern Ireland and Second Level in Scotland.
