What could it be? It was too big to fit through the door so it must have landed or appeared there. We went back to class and thought about some clues... The clock, the keyboard, the wires, the light bulbs... all things that led us to different conclusions.
One of us went on a special job to ask all the other classes if they had put the machine there, but they hadn't.
We were left to mull it over for the rest of the morning.
Message from a time-lord!
After dinner, Mr Littlewood told us that we had received a message about the special machine. It revealed that it was in fact a broken time machine!

The message said we had to learn about circuits so that we could help repair the time machine. Mr Littlewood didn't know what to do so he gave us lots of wires and batteries and bulbs to see if any of us could work out how a circuit works.
After we had found out for ourselves how circuits work through trial and error, we made circuit diagrams to help the time-lord mend his time machine.
We thought of some class 'top tips' for the time-lord and left him a message... let's see if the machine is still there tomorrow.
