Note: Record the angle of the shadow on the protractor. The string into the ground following the sun shadow. The time of data collection, wrap one end of the string around the nail that isĪt the quadrant origin point and use the other nail to anchor the other end of

Pound a large nail perpendicular to the quadrant at the origin (see drawing).

Glue the quadrant to the wide side of the stick ( see drawing).

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.

(approximately 25 x 25 cm), string(approximately 1.5 meter long), ruler. You need to measure the sun's angle of inclination. Periodically as an extension of the project. Something that could be a long-term fixture at a school that could be viewed 21 or 22 and June 19, 20, 21 or 22 with all the other students and schools participating in this project.Ī precursor to Activity 6 and students just see how the angle falls without Enter the current date and solar noon time into your project journal.When the shadow of the Sun touches the northern short stick, the time is solar noon. Plant the second short stick 0.5 meters south of the meter stick. Plant a short stick 0.5 meters North of the long stick.

Tools needed: a meter stick and 2 short sticks, compass, The time varies between 11:00 am and 1:30 pm depending on your latitude and longitude and the calendar date. Solar noon does not occur at 12:00 pm each day. Solar noon occurs when the sun is at it's highest point in the sky and produces the shortest shadows.
