Genes, cell division and natural selection learning stations bring real biological examples into your Grade 9 science classroom. Designed for Alberta Science 9 Biological Diversity, this activity helps students investigate how genes and chromosomes contribute to inheritance, how mitosis and meiosis differ, and how natural selection, selective breeding and genetic technologies affect living organisms.

Rather than studying biological processes in isolation, students examine documented cases, record scientific evidence and compare the benefits, limitations and ethical considerations of different processes and technologies. The station-based approach provides opportunities for scientific reasoning, communication and collaborative discussion.

What Makes This Activity Different?

Students connect introductory genetics concepts with real-world biological examples. Each station provides a focused case for investigation, allowing learners to consider scientific evidence while developing their ability to explain biological processes and evaluate their applications.

The activity connects inheritance and genetic variation with broader questions about biological diversity. Students explore the roles of cell division, consider evidence involving natural selection and selective breeding, and examine questions associated with genetic technology.

What's Included

• Station case-study cards: Reading materials presenting real examples involving the lesson's biological concepts.
• Station recording sheet: A structured place for students to document information and evidence as they investigate each case.
• Station wrap-up: A concluding activity that supports reflection and comparison across the investigations.
• Teacher guidance: Supporting information for organizing and facilitating the station activity.
• Answer Key PDF with Teacher Guide: Includes learning objectives, teaching tips, discussion questions and common mistakes to support classroom instruction.

Biological Concepts Students Investigate

Students examine the relationship between genes, chromosomes and inherited characteristics. They distinguish the broad outcomes of mitosis and meiosis, including their connections to growth, inheritance and genetic variation.

Through evidence-based case studies, learners also investigate natural selection, selective breeding and genetic technologies. These examples provide a foundation for discussing how biological processes differ and why scientific evidence matters when evaluating their applications.

Using the Stations in Your Classroom

Arrange the case-study cards around your classroom and organize students into small groups. Groups visit each station, examine the information provided and document their findings on individual recording sheets. After completing the rotations, students use the wrap-up activity to consolidate their observations and compare evidence across the cases.

Use the accompanying teacher guide to prepare discussion prompts, establish learning goals and anticipate common misconceptions. The activity can support a Biological Diversity lesson sequence, provide opportunities for collaborative investigation or serve as a review of introductory genetics and selection concepts.

Develop Scientific Thinking Through Real Cases

This resource combines genetics content with scientific inquiry. Students practise identifying relevant evidence, comparing biological processes and communicating reasoned conclusions. Examining the benefits, limitations and ethical considerations of biological technologies also encourages thoughtful discussion beyond basic vocabulary recall.

Bring together inheritance, cell division and selection through a structured learning stations activity that connects scientific concepts with documented biological examples.
