Thursday in Year 6 was science day. We began our day looking at light and how we can see. The children worked in groups and used wool to help them see how rays of light travel; they only ever travel in a straight line.
Next, once we understood that, we looked at how light is reflected. Using mirrors, card and a torch, we were able to create an incident ray and a reflected ray. We realised that because of the law of reflection, the angles were identical.
After break, we then had the challenge of making our own periscope. Although it was tricky and some instructions were quite vague, all of the groups managed to work together to make their periscope successful. Excellent job everyone.
Our final activity of the day was to do with refraction. We had glasses of water and a variety of images and lines. We noticed that when we put the empty glass in front of the line, the line appeared to jump up. However, when we filled the glass with water the line moved down. We learnt that this was refraction. We then put the image below the glass and filled it with water. We could still see the image. Next, we put a book on top of the glass and suddenly the image was gone! We then realised that, that was because we had taken away the light source which meant that we could no longer see it below the water.
