“Have you ever played outside all day and noticed that the length and location of your shadow changed as the hours went by?”
You probably also noticed that the sun changed location in the sky throughout the day too. The sun’s change in location caused a difference in the size, shape and direction of your shadow.
This week our Year 2’s grabbed the opportunity to work with a real sundial and see first-hand how it works.
We set up a “home-made” sundial on our tennis court using a bucket filled with sand, holding a tall stick in its center. Each Year 2 class was taken out to observe this “make-shift” sundial at 3 different points in the day. Every time a child is chosen to draw a line in chalk exactly where the shadow of the tall stick is at that point. The time of observation is written next to the drawing, for the next class to come out a little later to observe and record their results.
The students thoroughly enjoyed the realism and practicality of this experiment. They enjoyed being able to go back to class and record the data they had collected, drawing pictures for each observation taken. They have now seen, first-hand, the way in which a shadow moves throughout the day as well as how and why the sundial came about.
