Share poems in We are Britain by Benjamin Zephaniah to inspire children to write poems about themselves. Can children recognise their own Wanted poster? Suitable for Y6 pupils.

Look at an irreversible change. Children set up an investigation to answer questions about nails rusting. Will they compare nails made from different materials or find out whether or not both water and air are needed for rusting to occur? Suitable for Y6 pupils.

Use findings from Rusty Nails Investigation to plan another test. Look at the changes that occur when common materials are heated, and then decide whether or not cooling will reverse the change. What happens if the materials are first cooled and then heated? Suitable for Y6 pupils.

Find out what children already know about materials and the changes that occur when they are mixed. Predict and investigate what happens when a variety of materials are mixed with water. (Re)introduce terms reversible and irreversible. Play a vocabulary game. Suitable for Y6 pupils.

Session 1 - Have discussion about contraceptives as a way of preventing an unwanted pregnancy, but also explain that they can help protect against sexually transmitted infections and diseases. Use drama to practise saying no to peer pressure for smoking, alcohol or drugs. Children design warning labels.
