Hard Grade 4 worksheet on light interactions: reflection from mirrors, absorption by dark surfaces, and refraction through water and lenses. Four multiple-choice items and five fill-ins push students to apply NGSS 4-PS4 vocabulary to flashlights, black T-shirts, pencils in water, and quiet rooms. Students reason about reflection in mirrors, refraction through lenses and water, and absorption by dark surfaces in challenging Grade 4 multiple choice and fill-in items.
Style:
Waves: Light and Sound
Part A: Multiple Choice
Circle the best answer for each question.
1. A Grade 4 student shines a flashlight at a flat mirror. What happens to most of the light?
A) It is absorbed and turns into heat inside the mirror.
B) It is reflected back at an equal angle.
C) It is refracted and bends straight downward.
D) It disappears completely with no path.
2. Why does a black T-shirt feel hotter in the sun than a white T-shirt?
A) Black shirts reflect more light than white shirts.
B) Black shirts absorb more light energy and turn it into heat.
C) Black shirts refract sunlight into rainbows.
D) Black shirts let light pass through without changing.
3. A pencil placed in a glass of water looks bent at the water line. What is happening?
A) The pencil really breaks when it touches water.
B) Light is absorbed by the pencil completely.
C) Light refracts (bends) as it passes between water and air.
D) Sound waves push the pencil sideways.
4. Which Grade 4 example best shows light being mostly absorbed?
A) Sunlight bouncing off a clean mirror.
B) A beam of light bending through a magnifying glass.
C) Sunlight hitting dark asphalt and warming it up.
D) A flashlight shining through clear glass.
Part B: Fill in the Blank
Write the correct answer on each line.
1. When light bounces off a smooth surface and changes direction, that is called reflection.
2. When a dark surface takes in light energy and warms up, that is called absorption.
3. When light bends as it passes from air into water or through a lens, that is called refraction.
4. Sound can also reflect off a hard wall or cliff, and the reflected sound we hear is called an echo.
5. Soft pillows and thick curtains help quiet a room because they absorb sound waves.
