Measuring the Sun's Altitude Using the SunShIP Data Sheet |
As the directions on the Data Sheets indicate, the method for measuring the Sun's altitude calls for
you to make a triangle using a shadow stick and then measure the angle that represents
the Sun's altitude above the horizon. |
|
Place the data sheet on a flat surface and then hold the stick or pencil upright
on the spot indicated on the Data Sheet.
Turn the paper under the pencil or stick so that the shadow is parallel with
the line on the Data Sheet.
Note: You may want to fasten the paper using tape if the wind is blowing.
Use a pencil or marker and trace along the length of the shadow.
|
|
Next, lay the stick or pencil down so that it is parallel with the bottom
line on the Data Sheet.
|
|
Trace a line along the length of the pencil.
To complete the triangle draw a straight line that will connect the end
of the pencil line to the end of the shadow line.
|
|
Place a protractor as shown and measure the angle. This angle is the
altitude the Sun is above the horizon.
Record this information.
