1. Wait until the sun has set and pick a bright star in the sky.

2. With the arc of the quadrant facing towards you, look along the straight edge, through the tiny gap between the sights.

3. Line up the star between the sights, so it looks as though it is resting on the end of the quadrant.

4. Let the string hang down and then hold it in place.

5. Read off the number on the arc. That number is the height of the star in degrees.

6. The stars will be in a different place in the sky depending on:
a) the time of night
b) how far north or south you are

...If you are too excited to wait until night fall!

1. Cut out and colour in the star from the template.

2. Stick the star at different points on your wall.

3. Practise measuring its height in degrees.

Warning! You should never look directly at the Sun. It can make you blind.
