Light & Sound — Answer Key
Part A: Multiple Choice
Circle the best answer for each question.
1. Which object would make the LARGEST shadow with a flashlight?
A) A tiny bead
B) A pencil
C) A big cardboard box
D) A paperclip
Larger objects block more light, so they cast the biggest shadow.
2. What happens if you move a flashlight closer to a toy?
A) The shadow gets bigger
B) The shadow disappears
C) The shadow gets smaller
D) Nothing changes
Moving the light closer spreads the blocked area, making the shadow grow.
3. Which surface would show a shadow most clearly?
A) A rough rock
B) A white wall
C) A dark closet
D) A mirror facing down
A plain white wall reflects light well so the dark shadow stands out.
4. If you stand behind a transparent window, what will your shadow look like?
A) Very dark
B) Very faint or none
C) Huge
D) Rainbow colored
Transparent windows let most light through, so only a faint shadow or none forms.
Part B: Fill in the Blank
Write the correct answer on each line.
1. A shadow is always found on the side opposite from the light.
Light travels straight, so the blocked area lies behind the object.
2. If the sun is behind you, your shadow is in front of you.
The sun's light hits your back and your shadow stretches out ahead.
3. Two lamps aimed at one toy can make two shadows.
Each light source creates its own shadow, so two lamps give two shadows.
4. Moving the toy closer to the wall makes its shadow sharper.
Closer objects give shadows with clearer, sharper edges on the wall.
5. If you block the flashlight fully with your hand, the shadow is very dark.
A hand is opaque, so it blocks all the light and the shadow is very dark.
