Mar18 Shadow stick enquiry! Posted on March 18, 2016 by year5teacher Shadow stick enquiry! Yesterday we carried out an enquiry to see how the movement of the sun changes throughout the day. We asked ourselves: Is there a relationship between the time of day and the size of a shadow? Throughout the day we measured a show stick to answer our enquiry question. What did we find out? Why did the show change size? What questions do we have now?
