To make a sundial you will need:
- card
- glue
- a direction compass (to find north and
south)
- a drawing compass (to draw a circle
with)
1. Using the template provided below, cut
out the two shapes from the cardboard.
2. Fold out the two long straight flaps so
that they are in opposite directions.
3. Glue together the two triangles.
4. Draw a semicircle on the cardboard base.
5. In the centre of the semicircle, with
the thin point of the triangle at the edge of the card,
glue the sundial to the base. Make sure you assembled sundial
looks like the one in the diagram below.
How to use your sundial
1. Place your new sundial in the sunshine,
making sure it is on something level.
2. Turn the sundial until it is facing south,
use your compass to do this part (use the picture below to make
sure you have the right side facing south).
3. Now you can use the sun to tell what the
time is. Every hour mark the time and the position of the shadowing
on the card. Don't worry if you miss an hour, you can estimate
where that hour is by seeing how far there is between the shadows
of the other hours.
4. Once you have marked down where all
the daytime hours are, you will have a fully working sundial.
