Images of the tools for measuring the Sun's angle

You need to measure the sun's angle of inclination.

Tools needed: Apparatus from Activity 5 and 2 nails (approximately 10 cm),thin cardboard (approximately 25 x 25 cm), string(approximately 1.5 meter long), ruler.

Obtain a meter stick.
On a piece of thin cardboard draw a quadrant (1/4 of circle) using a protractor that has lines indicating every degree from zero degrees to 90 degrees.
Glue the quadrant to the wide side of the stick ( see drawing).
Pound a large nail perpendicular to the quadrant at the origin (see drawing).
On a sunny day, at the time of data collection, wrap one end of the string around the nail that is at the quadrant origin point and use the other nail to anchor the other end of the string into the ground following the sun shadow.
