King Charles of all people wrote an impassioned letter to the children of Scholes asking them which material would keep his tea warm the longest.
Pupils in 5/6 investigated three materials:
- tin foil
- felt
- bubble wrap
They considered the independent, dependent and control variables before conducting the experiment.
Help at home:
- Repeat the experiment with different materials
- would a lid have changed the results
- Consider why the results were so similar
