Lesson Title: Algae and Plants Year: 11
Topic: Chemistry of the Atmosphere Unit:
Staff members: Mr. S Guy
Date Set: 01/01/2021
Information to read / watch: https://www.bbc.co.uk/bitesize/clips/zhrmhyc
Application: Objective: Explain how plants have caused the concentration of oxygen in the atmosphere to increase
Objective: Describe photosynthesis as a balanced symbol equation and a word equation.
Objective: Describe how the formation of limestone and coal changed the atmosphere.
Task: Explain fully how oxygen first came into the atmosphere from a carbon dioxide rich atmosphere. Explain one other way in which carbon dioxide has been removed from the atmosphere over time.
Scaffold: Comparison of Early and Modern Earth atmosphere
Task: Write the word and balanced symbol equation for the photosynthesis equation.
Scaffold: Blank equation sheet. Match the words to the symbols.
Task: Describe the effects of the formation of limestone and coal on the composition of the atmosphere.
Scaffold: Diagram of the formation of limestone. Diagram of the formation of coal.
Challenge: Explain how humans are currently changing the Earth’s atmosphere and how this changed during the lockdown of Spring 2020.
Scaffold: Graph of CO2 concentration since 1975 and NO2 concentration in 2020.
Misconceptions: The majority of questions compare the early atmosphere to current atmosphere NOT current human impacts (eg climate change).
