In this sheet we will think of different ways of telling the time. Part of this sheet will involve some constructional projects. Think of as many ways to tell the time as you can.
Hint Think of a venetian blind.
One way to tell the time is to use an equatorial sundial. Draw a disc for an equatorial sundial onto card, with a reverse disc on the bottom. Divide each disc into 24 segments corresponding to the hours of the day. Number one side from 1 to 24 clockwise and on the other side from 1 to 24 anticlockwise with the number 12 on the top and bottom coinciding. Stick a wooden skewer through the centre and adjust the length so that the needle makes an angle of your latitude with a horizontal table.
