Lesson Title: Today we are learning about
What is diffusion?

Remember to check for PROGRESS
Focus on Knowledge, Skills and Understanding

Success Criteria:	You will show your learning by...
Substances may move into and out of cells across the cell membranes via diffusion. Diffusion is the spreading out of the particles of any substance in solution, or particles of a gas, resulting in a net movement from an area of higher concentration to an area of lower concentration. Some of the substances transported in and out of cells by diffusion are oxygen and carbon dioxide in gas exchange. Some of the substances transported in and out of cells by diffusion are the waste product urea from cells into the blood plasma for excretion in the kidney. Explain how the difference in concentrations (concentration gradient) affect the rate of diffusion. Explain how the difference in the temperature affect the rate of diffusion. Explain how the surface area of the membrane affect the rate of diffusion.

Keywords:

Waste Product: A chemical substance released by cells as a by-product of metabolic reactions. (1)
Concentration: The amount of a substance in a given volume. (1)
Concentration Gradient: The difference between a high and low concentration. (1)
Diffusion: Passive movement of particles from a high to a low concentration. (1)

AFL/Key Questions:

How do substances move in and out of cells?
diffusion
What is the definition for diffusion?
Diffusion is the spreading out of the particles of any substance in solution, or particles of a gas, resulting in a net movement from an area of higher concentration to an area of lower concentration.
Name two substances that are transported in and out of cells by diffusion during gas exchange
oxygen and carbon dioxide
How does the waste product urea reach the kidney to be excreted?
Urea diffuses from cells into the blood plasma to reach the kidney for excretion
How does the concentration gradient affec the rate of diffusion?
The bigger the concentration gradient the faster the rate of diffusion will be
How does the difference in temperature affect the rate of diffusion?
The higher the temperature the faster the rate of diffusion
How does the surface area of the membrane affect the rate of diffusion?
The bigger the surface area the faster the rate of diffusion will be

Remember to check for PROGRESS

Starter Activity	Differentiation and Challenge question/task
Students to copy and complete the keywords. Teacher reveals missing letters; Students correct mistakes; Discuss the scientific meanings of the words. Students to write down the definitions of the most important / new keywords. Discuss the 'Memory Anchor'. What does it show? How does it relate to the what we are learning about today (title)?

Think about PACE – Develop, consolidate and deepen knowledge, skills and understanding
