In the Grade 8: Fluids
unit, students learn that fluids are essential to many industrial processes and form the basis of hydraulic and pneumatic devices. Any substance that flows is considered to be a fluid. Fluids include such things as water, shampoo, sunscreen, and honey. Even gases, such as air, can be classified as fluids. In this unit, students also learn about the diverse applications of the principles involved in fluid mechanics
This activity packet provides you with lessons, activities, readings and rubrics that can be used to address the following Grade 8 Science overall expectations:
- Analyze how the properties of fluids are used in various technologies, and assess the impact of these technologies on society and the environment.
- Investigate the properties of fluids.
- Demonstrate an understanding of the properties and uses of fluids.
This packet also addresses the following big ideas:
- Fluids are an important component of many systems.
- Fluids have different properties that determine how they can be used.
- Fluids are essential to life.
What lessons are included in this packet?
This packet is thorough in the sense that it includes 21 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 the properties of fluids. The lessons included in this packet are:
Lesson 3.1: What are Fluids?
Lesson 3.2: Exploring Fluids
Lesson 3.3: Viscosity
Lesson 3.4: Density, Mass and Volume
Lesson 3.5: Particle Theory

There are 21 activity worksheets, 11 readings, 6 self-reflection cards, and 9 rubrics. There are also 3 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.
What experiments or investigations are included?
There are also 6 investigations presented in this packet for students to explore the properties of fluids:
Investigation 3.1: Viscosity
Investigation 3.2: Mass-to-Volume Ratios
Investigation 3.3: Density
Investigation 3.4: Flow Rate and Viscosity
Investigation 3.5: Compressibility
Investigation 3.6: Buoyancy
What assessments are included?
There are 9 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 no final test as students had previously demonstrated their understanding of the unit concepts in a variety of other ways. However, there are 2 quizzes presented in this packet.
