Lesson 1: Lasers and Photonics

(K) What I already know about the topic	(W) What I want to know about the topic	(L) What I have learned about the topic
A photon is the smallest unit used to measure light	How lasers work
Photons are used in our daily lives and are very useful	How the theory of photonics works
Lasers have several uses but can be extremely dangerous

Lesson 2: Reflection of Light

(K) What I already know about the topic	(W) What I want to know about the topic	(L) What I have learned about the topic
Light always travels in a straight line	How convex and concave mirrors work in detail
Light is a form of energy that cannot be created nor destroyed	How the reflection of light can be affected by external factors
An object can be seen because light has reflected off it
When light hits a surface, the angle which it leaves the surface at is the same as the angle it hit the surface at
