What happens when light strikes an object? (Standard: SC.3.P.10.3)

• It disappears completely

• It bends around the object

• It can be absorbed, reflected, or refracted

• It slows down and stops

What does it mean to absorb light? (Standard: SC.3.P.10.4)

• To reflect all light waves

• To take in or soak up light

• To make light travel in a straight line

Why does an apple appear red? (Standard: SC.3.P.10.4)

• It reflects all colors of light

• It absorbs red light and reflects all other colors

• It absorbs all colors except red

• It bends red light

What is reflection? (Standard: SC.3.P.10.3)

• When light bounces off a smooth surface

• When light bends as it passes through something

• When light is completely absorbed

• When light changes into heat energy

What is refraction? (Standard: SC.3.P.10.3)

• When light bounces off a smooth surface

• When light bends as it passes through a material

• When light travels in a straight line

• When light is absorbed

Why does a pencil in water appear broken?

• The water absorbs the light

• The light reflects off the pencil

• The water bends the light, making the pencil look broken

• The water creates a shadow

Why can you see your reflection in a mirror but not on a desk or wall?

• Mirrors absorb more light

• Mirrors have a smoother surface

• Walls do not allow light to pass through

• Desks and walls reflect too much light
