In the Grade 8: Cells
unit, students are introduced to what cells are. Cells are the smallest unit of life, and each cell is a system nested within a system. In this unit, students develop their knowledge of organisms by focusing on the structure and function of cells in plants and animals. Students also explore the impact that our understanding of cells and cell processes have on both human health and the environment.
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 impact of cell biology on individuals, society, and the environment.
- Investigate functions and processes of plant and animal cells.
- Demonstrate an understanding of the basic structure and function of cells and cell processes.
This packet also addresses the following big ideas:
- Cells are the basis of life.
- Cells organize into tissues, tissues into organs, organs into organ systems, and organ systems into organisms.
- Healthy cells contribute to healthy organisms.
- Systems are interdependent.
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 cells and cellular processes. The lessons included in this packet are:
Lesson 1.1: What is a Cell?
Lesson 1.2: Living Things
Lesson 1.3: The Cell Theory
Lesson 1.4: Cell Structures
Lesson 1.5: Cell Structures
Lesson 1.6: Plant and Animal Cells

Lesson 1.22: Cells Review
There are 30 activity worksheets, 12 readings, 5 self-reflection cards and 8 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. There are experiments included in this packet:
Experiment 1.1: Microscope Investigations
Experiment 1.2: Preparing Slides
Experiment 1.3: Osmosis and Diffusion
What assessments are included?
There are 2 assignments in this packet:
Assignment 1.1: Human Organ Systems
Assignment 1.2: Structures and Organelles
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 8 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.
