Task Description
Students built a periscope on their own with the materials given. Through the making of a periscope, student could better understand two concepts they learnt about light. This includes the reflection of light and that light always travels in a straight line. This is a real-life application of plane mirror and light reflection. Besides that, students could also better understand how periscopes help submarines to view from under the sea by testing it out themselves. They could also bring home the periscope and share all their findings with their family.

Student's Reflection
This experiment showed us what happens when light hits a plane mirror in a periscope. It showed us that it will reflect in a straight line and these reflections can be seen more than once. I learnt that light can be reflected multiple times by putting mirrors face to face.
I enjoyed making and testing the periscope the most because I have never had a periscope of my own, and it was interesting to see the mirrors reflecting images. I would like to learn more about convex and concave mirrors as we mostly only talked about plane mirrors.
Teacher's Comment
Grayson fully understands the concepts behind how light is reflected in the periscope, and he also brought it to the next level. He was able to design a periscope in drawing in his booklet with 4 mirrors. Grayson shows curiosity in learning Science, and he is always thinking more to better understand the concepts he learnt in his self-learning. Well done, Grayson.
