Science 8 – 4.1

cells

Learning Outcomes

• illustrate and explain that the cell is a living system that exhibits the following characteristics of life (304-4)
• explain that growth and reproduction depend on cell division (304-6)
• distinguish between plant and animal cells (304-5)

• use a light microscope or microviewer correctly to produce a clear image of cells (209-3)
• work co-operatively with team members to develop and construct models of cells (211-3)
• explain that it is important to use proper terms when comparing plant and animal cells (109-13)

Students will be able to illustrate and explain that the cell is a living system that exhibits the characteristics of life like growth and reproduction.

Experiment – using a light microscope to correctly view a clear image of cells. Students work in groups to develop and construct models of cells.
