Product Description
In the Grade 8: Systems in Action unit, students learn about the systems that help to make our lives and the lives of others easier. The needs of society can influence the evolution of systems, or demand the introduction of new systems. All systems are made up of many components that can be studied and improved. Students learn to calculate the mechanical advantage of mechanical systems, and will learn about the overall safety, efficiency, and effectiveness of a variety of systems.

This activity packet provides you with lessons, activities, readings and rubrics that can be used to address the following Grade 8 Science overall expectations:
- Assess the personal, social, and/or environmental impacts of a system, and evaluate improvements to a system and/or alternative ways of meeting the same needs.
- Investigate a working system and the ways in which components of the system contribute to its desired function.
- Demonstrate an understanding of different type of systems and the factors that contribute to their safe and efficient operation.

This packet also addresses the following big ideas:
- Systems are designed to accomplish tasks.
- All systems include an input and an output.
- Systems are designed to optimize human and natural resources.

What lessons are included in this packet?
This packet is thorough in the sense that it includes 22 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 systems in action. The lessons included in this packet are:
Lesson 2.1: Introducing the Unit
Lesson 2.2: Types of Systems
Lesson 2.3: Purpose of Systems
Lesson 2.4: Purpose, Input and Output
Lesson 2.5: Components of Systems
Lesson 2.6: Simple Machines
Lesson 2.7: Comparing Terms
Lesson 2.8: Forces
Lesson 2.9: Calculating Work
Lesson 2.10: Systems Quiz
Lesson 2.11: Mechanical Advantage
Lesson 2.12: Mechanical Advantage: Lever
Lesson 2.13: Mechanical Advantage: Pulley
Lesson 2.14: Calculating Work
Lesson 2.15: Working with Formulas
Lesson 2.16: Efficiency
Lesson 2.17: Efficiency
Lesson 2.18: Automation
Lesson 2.19: System Evolution
Lesson 2.20: Creating Systems
Lesson 2.21: System Functioning
Lesson 2.22: Systems and Needs

There are 34 activity worksheets, 11 readings, 6 self-reflection cards, and 9 rubrics. There are 3 assignments presented in this unit. These assignments are:
Assignment 2.1: Components of a System
Assignment 2.2: Evolution of a System
Assignment 2.3: Creating Systems

What assessments are included?
There are 9 rubrics to assess student understanding of the concepts addressed in this unit. There are also 6 exit cards presented in this packet that can be used at the end of a lesson to identify what students have learned about the concepts addressed in this unit. Please note that there are only 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 one quiz midway through the unit. There is no final test as students had previously demonstrated their understanding of the unit concepts in a variety of other ways.
