1.Does the shortest shadow of the meter stick always fall at clock noon? If not, why not?

2. Solar noon is the exact time that the Sun is at the mid-point of the daytime sky. How does our location within a time zone determine when solar noon will occur?

3. Do you find any pattern within the data? Does your school data match any pattern seen in the data from the other schools? Explain.

4. Is there any conflicting data from other reporting schools? Explain.

5. Why are these angles of the shadows only possible on the fall and spring equinox?
