Sundial Time!!!

   While researching how the earth revolves around the sun and how the sun "rises" in the east and "sets" in the west we came across a picture of a sundial. We knew we just had to make our own! We learned about the different parts of the sundial and found things in our room that were similar. We used a piece of paper as the face and a pointer as the gnomon. We then made a mark around the time we placed it outside (based on a sundial face diagram we found on NASA's websited) and came back an hour later only to find that it really had moved to keep time! The kids were fascinated! =)


 Here is the sundial; the two little marks are the frame for where the gnomon case it's shadow at the beginning of the exploration and you can see where the shadow was an hour later!!!
