light source | anything that makes light whether natural and artificial |

transmit | goes through |
independent variable | variable that is changed |

experimental question | questions that are answered by conducting tests and collecting evidence about a phenomenon or problem |
silvering | silver-colored material used to coat glass in order to make it reflective |
transparent | a material that allows light to pass through so that objects behind can be seen |

visible light | the only wavelengths of the electromagnetic spectrum that humans can see |
brightness | a measure of the amount of light reflected by a material |
light waves | one of the ways that energy travels though space (electromagnetic radiation) |
mirror | a reflective surface that reflects a clear image |
prism | a piece of glass that can separate white light |
sense receptor | an organ that has nerve endings that respond to stimulation |
