When wood is magnified many times, it looks like tiny tubes. Sometimes the surface of __________ is shiny.

Scattering is what occurs when light bounces off of surfaces that are not smooth. Many objects that ______________ light feel smooth when you touch them.

If you could take an object that scatters light, like a piece of wood, and smooth out all the bumps and ridges, then the object would reflect more _________ and scatter less light.

Reflection is what happens when light bounces off of a surface that is very smooth. A ____________ has a very smooth surface.

Light travels in straight lines.

Light continues traveling until it reaches an object.

When light bounces evenly off a very smooth surface, like a mirror, it is called _____________________.

When light bounces off a rough surface, like paper, it is called_____________.

The way light is scattered or reflected from objects affect whether an image can be seen or not in the object.

When a person looks in a mirror, it looks like they are seeing objects on the other side of the ___________.

Eyes are like sensors of the light rays that hit them. People can only see light that enters their ____________.

In a mirror, it looks like the light is coming from a source that is on the other side of the mirror. For a sheet of paper, the _____________ is scrambled, so it does not look like it is only coming from one place.

People sometimes refer to using your eyes with no magnifying glass or microscope as “seeing with the naked ________.”

Reflection is what happens when light bounces of a surface that is very smooth. A ___________ has a very smooth surface.

Models are simplified representations of phenomena.

What are the two ways that light can bounce off an object?

How are reflecting and scattering similar and different?

What determines whether a surface will reflect light or scatter it?

Why can a person see a reflection in a mirror, but not in wood?

Scattering occurs when light bounces off an object in all directions. This occurs when the surface of the object is rough and unpolished.

Reflection occurs when light bounces off an object only in a certain direction. This occurs when the surface of the object is smooth and polished.

A reflection of one object is seen in a second object only if the second object reflects light, not if it scatters it.

Which word is NOT a description of the surface of polished wood?
