Course overview
Learners will return after the Easter break to finish off their topics from the previous term and then will move onto their new topic, Movement in Cells:
Movement in Cells: Learners recap the types of cells and structure and function of the organelles. They will learn about diffusion, osmosis and active transport - focusing on what these types of movement are, how they work and specific mechanisms and adaptations that are required for organisms to carry out these processes. . They will learn about the effect of surface area to volume ratio (including how to calculate it) and how this affects an organisms’ ability to effectively take in substances by these processes. They will plan, carry out and interpret the osmosis required practical which investigates the effect of osmosis on plant tissue. They will analyse data graphically and interpret how this can be used to estimate concentration of plant tissue.
Key Concept:
Diffusion, osmosis, active transport
Assessment Points:
End of unit assessment will consist of a 40 mark test
Midway assessment set by class teacher which could be an exam question
Guidance:
Learners will receive guidance in a variety of ways. These include marked assessments, reports, feedback in books, 1:1 interaction, Google Classroom.
