We have now started our 3rd big investigation. This time we are looking at how the change in the clocks this coming weekend will affect us. We have been recording how much sleep we have every night in a sleep diary, and how alert we are in the morning ( using the Karolinska scale).

We are doing reaction experiments on a morning and afternoon before and after the clocks change to see whether our reaction rate changes.

Our results will uploaded onto the BBC Terrific Scientific website and they will be analysed by Oxford University. It will be interesting to see the results of the whole investigation.
