| prism | clear, solid object that bends light |
| reflection | bouncing of light off an object |
| absorption | stopping of light |
| refraction | bending of light when it moves from one type of matter to another |
| opaque | term for an object you cannot see through |
| transparent | term for an object you can see a clear image through |
| translucent | term for an object you can see a blurry image through |
| visible spectrum | all the colors of light that people can see |
| 3 examples of things light energy does. | lets us see things, helps doctors operate, helps plants grow, give things color |
| What is an example of reflection? | Seeing your face in a mirror |
| What is an example of refraction? | Light hitting a prism |
| What do prisms do? | They bend light |
| How does light travel? | In straight lines |
| When does the sun cast the longest shadows? | In the morning and the evening |
| Why can you see through water and glass? | Because light goes through them. |
| Give 3 examples of items that are opaque. | a chalkboard, a movie screen and a door |
| Give an example of a translucent object. | A stained glass window |
| What three colors of light will give white light? | red, green and blue |

| What do water droplets on a rainbow act like? | A prism |

| When are rainbows visible? | On sunny days when there are water droplets in the air |
| What must you have to see your reflection in a mirror | Light in the room |
| If you are wearing a red and blue shirt which colors are absorbed? | All colors except the red(the red part of the shirt) and blue (the blue part of the shirt) |
| What must happen for a surface to reflect light rays? | The surface must be smooth. If it is rough the light will bounce off in many directions |
| What does a concave mirror do? | Reflects light and makes things appear smaller |
| What does a convex lens do? | Does not reflect light and makes objects appear larger. |
| How are reflection and refraction alike? | They both change the direction of light |
| How are reflection and refraction different? | Reflection bounces light off a surface and refraction bends as it travels. |
