The best fuel
How does the length of the carbon chain affect the heat given out by different alcohols burning. The students had to design the most efficient way of capturing all the heat, and eventually understood about the amount of energy in bonds.

Partial Fractions
Working from GCSE to A level and from year 1 to year 2 at A Level. Spending some "slack time" catching up with things gone by and new ideas to come.

Distillation
Separating and collecting a liquid from two or more liquids. After the students had fermented some orange juice we collected some nice smelling alcohol which burnt really well. Surprised a few students that it did burn.
