• Object only

• Light source and an object

• None of the above

What happens to a shadow when the light source moves closer to the object?

• The shadow gets larger

• The shadow gets smaller

• The shadow disappears

• The shadow remains the same size

Which direction does a shadow form in relation to the light source?

• In the same direction as the light source

• In the opposite direction of the light source

• Perpendicular to the light source

• In a random direction

How does the time of day affect the length of a shadow?

• Shadows are longest at noon

• Shadows are shortest at noon

• Shadows do not change length during the day

• Shadows are longest at sunset

What can cause the shadow of an object to change direction?

• The color of the object

• The shape of the object

• The movement of the light source

• The size of the object

Why do shadows change length throughout the day?

• Because the Earth rotates around the Sun

• Because the light source changes in intensity

• Because the Earth rotates on its axis, changing the angle of sunlight

• Because the distance between the Earth and the Sun changes

What factor does not affect the size of a shadow?

• The color of the light source

• The distance between the object and the light source

• The angle of the light source

• The intensity of the light source

What happens to the shadow when the light source is at a lower angle in the sky?

• The shadow becomes shorter

• The shadow becomes longer

• The shadow remains the same length

• The shadow disappears
