Grade 4 Science · Light and Sound
Build Grade 4 Science skills with five 10-question practice tests on light sources, shadows, reflection, refraction, sound vibrations, pitch, volume, and hearing safety.
These Grade 4 Science practice tests help students explain how light and sound carry energy and interact with materials. Students identify light sources, shadows, transparent and opaque materials, reflection, refraction, sound vibrations, pitch, volume, echoes, and hearing safety.
For light questions, identify the source and notice whether light is blocked, reflected, or bent. For sound questions, identify what vibrates, how the vibration travels, and whether the sound is high or low in pitch or loud or soft in volume.

Correct answer: A
The correct answer is A bright desk lamp turned on.
A bright lamp is a light source that can illuminate the book.
Please select an answer first.
Correct answer: B
The correct answer is Light can travel through empty space, but sound needs matter to travel..
Light can travel from the Sun through space, while sound needs a medium such as air.
A shadow forms when an opaque object blocks light from reaching a surface behind it.
Sound is produced when an object vibrates and transfers energy through a medium such as air, water, or a solid.
