Keeping warm - heating
It was cold April day and the central heating was keeping us cosy indoors. We knew that the central heating system has a thermostat and it cuts off a boiler when the room is warm enough. But there's just a thin piece of glass between us and the outside and we wondered if it really helped much.
What we did
We decided that we needed to measure the temperature both inside and outside the window. We also thought it would be good to use a light sensor to monitor the day light, that way we could record when the day began and ended. We connected the sensors to a data logger because it can make all those measurements automatically and store them till we are ready to look at them.

What you can do
Winter: how does the central heating affect these results? Repeat our experiment and compare a room which is centrally heated with say, a garden shed which is not.
