Periscope

Learning Intention: To explain how periscopes work?

Mr Johnston came and taught us about what periscopes are, who uses them, and how they are used.
We found out that the angle of incidence, equals the angle of reflection. That means if the light hits the mirror at 45 degrees, it reflects the light back at 45 degrees. This was fun because I liked using the periscopes and finding things interesting about it. I also like using mirrors to write my name backwards.
