This Mirror, Mirror on the Wall: Reflections of Light lesson plan also includes:
Why can we see our reflection in a window but not a brick wall? Young physicists learn the Law of Reflection and various light properties that help them answer this and other questions about reflection. Use the PowerPoint to introduce these concepts, but be sure to go more in-depth if this is your only explanation. Kids draw ray diagrams demonstrating the difference between light hitting smooth and rough surfaces, and view an online simulation that allows you to adjust the angle of incidence and wave length. Finally, follow the link to find an engaging reflection lab that scholars complete with partners.
