Key Concept 1: Light travels in straight lines until reflected or refracted
by another object.
Passage
The Sun is a star in our solar system that provides light, which is particularly
important here on Earth. The light from the Sun travels in a ______________
line in all directions from the Sun’s surface. When the light reaches a planet or
moon it bounces, or is _____________________, but can also bend, or is
__________________. Our Moon does not produce its own light, but rather
_______________ the light from the _________, which allows us to see it. If
we think about objects around us like the grass, the grass is reflecting the
green part of light, while absorbing the other colors!

Key Concept 2: Light is reflected when it bounces off of mirrors
or shiny surfaces. The image we see in a reflection is a flipped
image from the original.
Passage
Imagine you are watching a hairdresser cut your sister’s hair. You are watching
the whole event in the mirror, and can also see your sister in their hairdresser’s
chair. When the scissors were in the hairdresser’s right hand, the
__________________ in the mirror looked like it was moving its left hand!
Then when the comb was in the hairdresser’s left hand, the image in the
_____________ held it in her ____________ hand! This is because when light
bounces, or is _____________________ off a mirror we see the opposite
image. Try it in a mirror, how do things look?

Key Concept 3: Light is refracted, or bends, when passing from one
medium to another, such as from air into water. A refracted image is a
distorted or changed image from the original.
Passage
A student was observing an aquarium in the classroom. A leaf from a branch
of Elodea (a plant), as sticking above the surface and appeared
______________. The student thought about this for a minute, then realized it
wasn’t really broken, but the image looked that way because light was
_________________. A small fish then swam from one end of the tank to the
other side, and it suddenly disappeared! Then it was back again! How could
this happen? The student thought about it, and decided is also had to do with
how light ___________, or refracts when moving from air to glass to water.

Answer Key
The Sun is a star in our solar system that provides light, which is particularly important
here on Earth. The light from the Sun travels in a straight line in all directions from the
Sun’s surface. When the light reaches a planet or moon it bounces, or is reflected, but can
also bend, or is refracted. Our Moon does not produce its own light, but rather reflects the
light from the Sun, which allows us to see it. If we think about objects around us like the
grass, the grass is reflecting the green part of light, while absorbing the other colors!
