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.

3. Test
A 10-question Grade 4 Science practice test on light sources, shadows, transparent materials, reflection, refraction, sound vibrations, pitch, volume, and hearing safety.
Read each situation and choose the answer that best explains how light or sound behaves.
Please select an answer first.
Correct answer: A
The correct answer is Light bouncing from a surface.
Reflection occurs when light bounces off a surface.
Please select an answer first.
Correct answer: B
The correct answer is A dark black surface.
Dark surfaces absorb more light energy than shiny light-reflecting surfaces.
Please select an answer first.
Correct answer: C
The correct answer is A white sheet of paper.
Light-colored surfaces generally reflect more light than dark surfaces.
Please select an answer first.
Correct answer: D
The correct answer is Moving the object closer to or farther from the light source can change the shadow size..
The positions of the light source, object, and surface affect the shadow size.
Please select an answer first.
Correct answer: A
The correct answer is Glasses with lenses that reduce the amount of light entering the eyes.
Protective lenses reduce intense light reaching the eyes.
Please select an answer first.
Correct answer: B
The correct answer is Light bends as it moves between water and air..
Refraction changes the apparent position of the pencil.
Please select an answer first.
Correct answer: C
The correct answer is Mirrors reflect light around the object and toward the viewer..
Angled mirrors can redirect reflected light to the viewer’s eyes.
Please select an answer first.
Correct answer: D
The correct answer is Thick fabric panels.
Soft materials can absorb some sound energy instead of reflecting it.
Please select an answer first.
Correct answer: A
The correct answer is Most light passes through the water, although it may bend at the surface..
Clear water is transparent, and light can travel through it.
Please select an answer first.
Correct answer: B
The correct answer is Tighten the string so it vibrates faster..
A tighter string usually vibrates faster and produces a higher pitch.
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.
