THE SHADOW KNOWS Worksheet

Directions:

A. Go outside and measure the heights of everyone in the group, record data in form of a chart along with each student's name.

B. Measure the length of each person's shadow, record in the chart with height information.

C. Record time of day.

Questions:


1.  Explain why time of day would be important in shadow length.



2.  At the same time of day, would all shadows be in proportion to the height

 of the objects being measured?   Explain. 
 


3.  As the angle of the sun changes throughout the day, would the shadows 

change in proportion? 



4.  What are the two determining factors in shadow length?

Directions:

A. For each crater, measure the shadow length (L) and record in the space provided.

B. Assuming the angle of incoming light , Ø, is 34 degrees, use your measurements and the formula L * tan Ø = d to calculate the depth, d, of all the craters. Show your work.
