In the Grade 7: Heat in the Environment
unit, students are asked to explore what some sources of heat are in the environment. Students are introduced to what heat transfer is and the processes of conduction, convection and radiation. They are also asked to critically think about the impact that heat loss reduction methods have on the environment as well as the impact of conventional and alternative energy sources. This activity packet provides you with lessons, activities, readings and rubrics that can be used to address the following Grade 7 Science overall expectations:
- Assess the costs and benefits of technologies that reduce heat loss or heat-related impacts on the environment.
- Investigate ways in which heat changes substances, and describe how heat is transferred.
- Demonstrate an understanding of heat as a form of energy that is associated with the movement of particles and is essential to many processes within the earth’s systems.
This packet also addresses the following big ideas:
- Heat is a form of energy that can be transformed and transferred. These processes can be explained using the particle theory of matter.
- There are many sources of heat.
- Heat has both positive and negative effects on the environment.
What lessons are included in this packet?
This packet is thorough in the sense that it includes 20 in-depth lessons that help to cover the specific and overall expectations as well as the big ideas. Some lessons are designed to set the stage for students in terms of content knowledge and terminology, and other lessons are designed to have students further investigate heat and heat transfer. The lessons included in this packet are:
Lesson 4.1: What is Heat?
Lesson 4.2: Motion of Particles
Lesson 4.3: How is Heat Produced?
Lesson 4.4: Heat and Solids, Liquids and Gases
Lesson 4.5: Investigating Volume Changes
Lesson 4.6: Conduction
Lesson 4.7: Conduction
Lesson 4.8: Convection
Lesson 4.9: Convection
Lesson 4.10: Radiation
Lesson 4.11: Radiation and the Sun
Lesson 4.12: Greenhouse Gases
Lesson 4.13: Greenhouse Gases
Lesson 4.14: Humans and Greenhouse Gases
Lesson 4.15: Investigating Heat Transfer
Lesson 4.16: Heat Loss
Lesson 4.17: Reducing Heat Loss and Transfer
Lesson 4.18: Reducing Heat Loss and Transfer
Lesson 4.19: Conventional and Alternative Energy
Lesson 4.20: Let's Review
There are 31 activity worksheets, 12 readings, 4 self-reflection cards and 7 rubrics. Several of the activities presented in this packet can be used as assignments, but it is up to your discretion to use them as such.
What assessments are included?
There are 3 assignments in this packet:
Assignment 4.1: Minimizing Heat Loss
Assignment 4.2: Conventional and Alternative Energy Sources
Assignment 4.3: Heat Transfer Brochure
Each of the above assignments include a title page, an instruction page and a set of organizing sheets that students can use to organize their formal response. A rubric is also included for assessment purposes.
There are 7 rubrics to assess student understanding of the concepts addressed in this unit. Please note that there are a few answer keys provided in this packet, as many activities involve an open answer and it is up to you to determine whether students have appropriately demonstrated their knowledge. There is a final test along with two mini-quizzes that can be used to identify what students have learned about heat in the environment.
