Grade 4 Energy and Waves Practice Test

Build Grade 4 Science skills with five 10-question practice tests on energy forms, energy sources, energy transformations, waves, light, sound, and heat.

Energy and Waves Practice Tests

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.

Skills covered

  • Identifying motion, light, sound, heat, electrical, and stored energy
  • Recognizing renewable and nonrenewable energy sources
  • Explaining energy transfers and transformations
  • Understanding that waves carry energy
  • Describing reflection, shadows, pitch, volume, and sound vibrations
  • Applying energy and wave ideas to simple designs and investigations

How to use these practice tests

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.
