You have explored light and shadows in this module. You have found out what makes light and what affects or changes light. You discovered how light sources have changed over time and looked at some present and future uses of light.
Did you enjoy experimenting with white light and coloured light? Did you enjoy making a periscope and kaleidoscope?
