Energy and Heat Practice Tests

These Grade 7 Science practice tests build understanding of kinetic and potential energy, thermal energy, heat, temperature, conduction, convection, radiation, insulation, energy transformations, and conservation.

Skills covered

  • Distinguishing kinetic, potential, chemical, thermal, electrical, light, and sound energy
  • Explaining the difference between heat, temperature, and total thermal energy
  • Identifying conduction, convection, radiation, and insulation in real situations
  • Tracking energy transfers and transformations in systems
  • Applying conservation of energy to machines, motion, heating, and everyday technology

How to use these practice tests

For each question, identify the system and the energy form involved. Then trace where energy moves or changes and decide whether the evidence describes heat transfer, temperature, or energy conservation.

1. QuestionMultiple choice

What is energy?

Please select an answer first.

Correct answer: A

The correct answer is The ability to cause change or do work.

  1. Identify the energy idea: Determine whether the question concerns energy form, energy transfer, heat, temperature, or an energy system.
  2. Connect the evidence: Energy allows objects and systems to move, change, heat, produce light, or perform other processes.
  3. Check conservation: Energy can move or change form, but a complete system accounts for the energy rather than treating it as created or destroyed.

Energy allows objects and systems to move, change, heat, produce light, or perform other processes.

2. QuestionMultiple choice
