Active learning ideas
Cell division focuses on the cell cycle and the specific stages of mitosis, which are critical for growth, repair, and asexual reproduction. Students learn how DNA is replicated and then pulled apart to ensure daughter cells are genetically identical. This unit also introduces the concept of stem cells, covering their origin in embryos and adult tissues, and their potential to treat conditions like diabetes or paralysis.
Activity 01
Students use lengths of coloured wool to represent chromosomes. They physically move through the stages of prophase, metaphase, anaphase, and telophase to demonstrate how DNA is distributed equally.
Why is mitosis essential for multicellular organisms?
Activity 02
Divide the class into groups representing medical researchers, religious leaders, and patients. They research their assigned perspective and debate the use of embryonic stem cells in the UK.
What are the stages of the cell cycle?
Activity 03
Students create posters for different stages of the cell cycle (Interphase, Mitosis, Cytokinesis). They rotate around the room, adding peer feedback and identifying the key features of each stage.
What are the ethical considerations surrounding stem cell research?

A few notes on teaching this unit
Watch Out for These Misconceptions
Students often think mitosis happens in all cells at all times.
Explain that most of a cell's life is spent in interphase, performing its normal functions. Using a pie chart activity to map the duration of each stage helps students see that mitosis is actually a very short part of the cycle.
Stem cells are often confused with gametes (sperm and egg cells).
Clarify that stem cells are undifferentiated cells capable of becoming many types of body cells, while gametes are specialised for reproduction. Collaborative sorting tasks can help students categorise different cell types correctly.
Methods used in this brief
Cell Structure and Transport
An investigation into eukaryotic and prokaryotic cells, including the functions of subcellular structures. Students will also examine diffusion, osmosis, and active transport.
8 methodologies
Animal and Plant Organisation
A study of how cells are organised into tissues, organs, and organ systems. Focus areas include the human digestive system and plant transport systems.
