Yesterday we carried out an investigation into whether shadows change over the course of a day. At 9.30 we went into the carpark (where we could be sure that our chalking couldn't be rubbed off) and drew a line showing where our shadow was and measured it. Over the course of the day we went out again and looked at our shadows again and recorded their direction and length. We were amazed that the shadows got gradually shorter up until midday and then got gradually longer again up until the end of the school day.
Do you what this means and why this is?
We came up with the statement; the lower the sun the longer the shadow and the higher the sun the shorter the shadow.
