With a week of wall to wall sunshine, my P7 class finally got out sundial experiment completed. We made basic sundials.
Every hour (except 1.20pm which was during lunchtime) measurements were taken of the length of shadow and angle of shadow.
We then drew graphs showing how the length of shadow changed - decreasing then increasing. The other graph was the angle - we got straight line graphs and worked out that the angle was the same each hour, which brought us on to the Earth spinning and why the sun appears to rise and fall and many other interesting discussions.
