Gas Exchange in Insects and Unicellular organisms - AS Unit: Exchange and Transport (AQA)

Powerpoints and all associated worksheets are provided for this lesson, covering all aspects of the specification. The notes are written to match the exact details required to score full marks in the AQA past papers.

*The 1st slide refers to marking of the ‘exchange surfaces tasksheet’ - this worksheet (included) can be given out in the lesson prior and completed for homework, so that the first 10 minutes of this lesson can be used for peer marking. The introductory lesson on exchnage surfaces is usually taught before this one. If you would prefer not to sue this task, simply delete the words on the 1st slide! :)
