Thermal Energy and Temperature is a Grade 7 Science resource focused on the foundations of heat and thermal energy within the Ontario Heat in the Environment topic. Students use the kinetic particle model to distinguish temperature from internal energy, identify thermal energy sources, and explain why energy transfers from higher internal energy to lower internal energy.

Build the core thermal concepts through a reading passage that introduces average kinetic energy, total microscopic energy, particle interactions, thermal equilibrium, conservation of energy, and everyday sources such as sunlight, stoves, engines, and electrical devices. The passage also connects these foundations to later study of conduction, convection, and radiation.

What students practise

• Distinguishing temperature from internal energy using particle motion and interactions.
• Explaining the general direction of heat flow between warmer and cooler objects.
• Recognizing thermal equilibrium as a state with no net heat transfer.
• Identifying sources that add thermal energy to natural and built environments.
• Applying conservation of energy to thermal energy transfer.
• Using scientific vocabulary to explain thermal energy ideas in their own words.

Question types and activities

The worksheet combines a reading passage, multiple-choice questions, true-or-false questions, short-answer prompts, matching, a cloze passage, extended response, and a Did You Know section. Students move from identifying key ideas to explaining the difference between temperature and internal energy and evaluating the misconception that particles “want” to cool down.

Teacher-ready support

The purchase includes the student worksheet and a separate PDF answer key, plus a Student Notes & Lesson Summary supplement. A separate Teacher Guide provides Learning Objectives, Teaching Tips, Discussion Questions, and Common Mistakes, giving teachers practical support for introducing or reinforcing Grade 7 thermal energy concepts.

Use this Grade 7 Science thermal energy worksheet for classroom instruction, guided reading, independent practice, review, or discussion. Its progression from foundational vocabulary and concepts to short explanations and extended reasoning helps students connect temperature, internal energy, heat flow, thermal equilibrium, and energy conservation within the Heat in the Environment unit.
