Grade 4 Science · Energy and Waves
Build Grade 4 Science skills with five 10-question practice tests on energy forms, energy sources, energy transformations, waves, light, sound, and heat.
These Grade 4 Science practice tests help students identify energy forms and sources and explain how energy moves or changes. Students also study how waves carry energy and how light, sound, heat, and electricity behave in everyday systems.
Look for evidence of motion, vibration, light, heat, electricity, or a stored source. Ask where the energy begins, how it moves, and whether it changes form. For wave questions, identify what is vibrating and how the wave carries energy.

2. Test
A 10-question Grade 4 Science practice test on energy forms, energy sources, wave energy, light, sound, and energy transformations.
Read each science situation and choose the answer that best explains the energy source, energy change, or wave behavior.
Please select an answer first.
Correct answer: A
The correct answer is Energy.
Waves transfer energy, even when the material itself does not travel far.
Please select an answer first.
Correct answer: B
The correct answer is A medium such as air, water, or a solid.
Sound vibrations travel through matter such as air, water, or solids.
Please select an answer first.
Correct answer: C
The correct answer is Light can travel through empty space..
Light from the Sun travels through the empty space between the Sun and Earth.
Please select an answer first.
Correct answer: D
The correct answer is The sound has a higher pitch..
Faster vibrations are heard as a higher pitch.
Please select an answer first.
Correct answer: A
The correct answer is Larger vibrations.
Larger vibrations transfer more energy to the air and make the sound louder.
Please select an answer first.
Correct answer: B
The correct answer is Energy travels across the surface of the water..
The wave carries energy across the surface while the water mostly moves up and down.
Please select an answer first.
Correct answer: C
The correct answer is The object blocks light from reaching that area..
An opaque object does not let light pass through it, creating a darker region.
Please select an answer first.
Correct answer: D
The correct answer is Clear glass.
Clear glass is transparent, so most light can pass through it.
Please select an answer first.
Correct answer: A
The correct answer is The light reflects from the surface..
A smooth mirror reflects light so it can travel in a new direction.
Please select an answer first.
Correct answer: B
The correct answer is Less sound energy reaches the listener..
Sound energy spreads out as it travels, so less reaches a distant listener.
Energy is the ability to cause change or make things happen. It can appear as motion, light, heat, sound, electricity, or stored energy.
Waves carry energy from one place to another. Sound waves carry energy through matter, while light can travel through empty space.
