Particle motion and temperature are the focus of this Grade 7 Science worksheet on energy, heat, and thermal processes. Students connect temperature with the average random kinetic energy of particles and use molecular motion to compare different thermal states and pressures.

Build the Particle-Level Model

This resource helps students describe temperature through particle motion rather than treating temperature as an isolated measurement. Students examine how average random kinetic energy relates to temperature and how thermal energy depends on both particle number and phase.

The worksheet also applies molecular motion ideas to comparisons of thermal states and pressures. This gives students a particle-level framework for explaining differences in thermal conditions and connecting microscopic motion with observable physical states.

Practice Scientific Thinking in Multiple Formats

Students work through multiple-choice questions, true/false statements, short-answer questions, a reading passage, matching, a cloze passage, an essay, and a “Did You Know?” activity. The varied tasks ask students to identify relationships, apply particle-motion ideas, interpret scientific information, and communicate explanations in their own words.

Teacher and Student Support Included

• Student Notes & Lesson Summary supplement for instructional support and review
• Separate Teacher Guide PDF with Learning Objectives, Teaching Tips, Discussion Questions, and Common Mistakes

Use in an Energy and Thermal Processes Unit

This Grade 7 science worksheet can be used for guided instruction, independent practice, classroom review, or assessment when teaching particle motion, temperature, and thermal energy. The notes supplement provides additional support for the lesson, while the Teacher Guide helps teachers structure discussion and address common mistakes.

The resource is identified with the Alberta framework. Its emphasis on molecular motion, kinetic energy, particle number, phase, thermal state, and pressure gives students a coherent way to connect particle behavior with thermal concepts.
