This week, we finished off our autumn term science unit all about light. This involved doing a series of investigations, one of which looked at how light reflects and travels in straight lines. To do this, we gathered our equipment and worked in groups to mimic how a periscope allows us to see an object over an obstacle. It took some trial and error to get the mirrors at the right angle, but all groups were successful in the end!

Another experiment we carried out was on light refraction. We learned that light travels slower when passing through dense objects, causing it to bend or change direction, almost creating an illusion. We were fascinated to see how a horizontal arrow appeared to point in the opposite direction when we looked at it through the beaker of water.
