Inquiry Learning – ‘Let There Be Light’

Grade 4/5H and Grade 5L have been working on the Inquiry topic of ‘Light’ during Term 4. Our first experiment involved making a sundial or a shadow clock. This is the way they use to tell the time before we had watches or clocks.

We used a paper plate, some blu-tack and a straw. We set it up in the sunny area out the back of our classrooms. We weighted the clock down with a rock. We wrote it up as a Science experiment and went out every hour to measure how far the shadow had moved. We measured it at 9:30 am, 10:30 am, 11:30 am, 12:30 pm, 1:30 pm and 2:30 pm.

We had thought that the shadow would move the same amount each time however this was not the case. We discussed our findings and decided that some things could have affected our results. The wind may have blown our shadow clocks, other children may have knocked our experiments or even the chooks and the duck may have shown some interest.
