1) Find a sun dial, solar date, or analemma.

Find a sundial, solar date or analemma  and take a selfie with it. Lists of places to find sundials (1, 2), or solar date devices such as Mt Baker Ridge viewpoint. Most towns will have at least one, though often hidden at a park or school.

2) Clearly explain in words how to use your device and how the earth's motion explains how it works. It may help to annotate your pictures. For better sun dials ~1 minute precision is possible.
