Grade 6 Energy and Waves Practice Test

Build Grade 6 Science skills with five 10-question practice tests on energy forms, transformations, thermal transfer, sound, light, wave properties, reflection, refraction, and absorption.

Energy and Waves Practice Tests

These Grade 6 Science practice tests help students understand how energy is stored, transferred, and transformed. Students practice kinetic and potential energy, conservation, conduction, convection, radiation, mechanical and electromagnetic waves, amplitude, frequency, wavelength, sound, light, reflection, refraction, absorption, and transmission.

Skills covered

  • Identifying kinetic, potential, thermal, electrical, light, and sound energy
  • Explaining energy transfer, transformation, and conservation
  • Comparing conduction, convection, and radiation
  • Describing mechanical and electromagnetic waves
  • Connecting amplitude, frequency, and wavelength with wave behavior
  • Explaining reflection, refraction, absorption, and transmission

How to use these practice tests

For energy questions, identify the starting form, the ending form, and whether energy is transferred between objects. For wave questions, distinguish the medium, the direction of energy transfer, and properties such as amplitude, frequency, and wavelength. Use the interaction with a surface or material to identify reflection, refraction, absorption, or transmission.
