Dear G5 students, this is your homework.
Please find luminous, reflector, concave, and convex materials in your home.

1. Find some luminous object that able to produce its own light!
2. Find any materials that can reflect light (the bouncing back of light)
3. Lens is a two-sided piece of transparent material with one or both sides curved. Find any concave lens (a lens that is thicker at the edges than in the middle, making things look smaller).
