Module 2: Living Systems: Ecosystems, Cells, DNA, and Reproduction

How does energy move through an ecosystem? How do cells, microbes, body systems, DNA, and reproduction sustain life from one generation to the next?

In this five-week science module, students examine living systems from ecosystems and populations down to cells, genes, and molecules. They investigate energy flow, ecological sampling, cell structure, diffusion, osmosis, microbial growth, disease, immunity, and the coordinated work of human body systems. They then explore DNA, inheritance, natural selection, mitosis, meiosis, and reproduction using experiments, measurements, probability, and biological evidence.

Who is the course for?

This course is designed for homeschool students in Grades 7-9.

No previous science course is required. Core explanations are accessible to younger students, while optional Going Further readings and research questions give older or more advanced learners additional depth.

How the course works

The module contains 15 classes which can be taken at any pace; three classes per week yield a well paced five week course.

Each class includes:

• a short instructor video;
• a complete handout with structured reading-and-work lesson;
• questions and journal activities;
• a clear Words to Know glossary;
• an optional Going Further reading;
• opportunities to practise observation, measurement, explanation, and fair testing.

Most classes take approximately 45-55 minutes. Students complete hands-on experiments and investigation each week, using commonly accessible materials (no special science kits are required).

Certificates

Every student who completes the module receives a certificate of completion.

Students who complete this module together with any two additional Stream 1 science modules will also receive a certificate recognizing the completion of a full academic year of science study.
