The Great Sundial Investigation!

Finally the sun came out and were able to investigate how shadows can help us tell the time.

 We carefully drew around our shadows and measured them.

 We had to be careful not to get blown away by the wind!
 Every member of each group had a job and we had to work together to complete our investigation.

 We found that the shadows got shorter as we approached midday and then longer again in the afternoon. We also found that the shadows moved clockwise during the day.

So how does what we observed happening to our shadows during the day mean we can use shadows to tell the time?
