Mirrors

Teacher asks students to: - arrange a pair of mirrors so that they can see into the hallway outside the classroom; - look at their reflections in concave and convex mirrors (e.g., the front and back of a spoon) and observe other optical illusions; - give a presentation on natural sites and objects that behave like mirrors (Uyuni Desert, a lake, a screen, a window); - write words backwards to be able to read them the right way round in a mirror.
