LI: To explain how periscopes work
This week Diana and I worked together to make a DLO about periscopes. Mr Johnston came and taught us about periscopes and how they are used. Periscopes are like binoculars but instead you can see above without letting the person know who is above. I found this activity interesting as I was amazed at how periscopes work. I never knew that there were mirrors inside periscopes so I found this interesting. I also found out the angle of incidence equals the angle of reflection. This means that if light hits the mirror at a 45 degree angle it reflects the light back at a 45 degree angle.
