Lesson 3: Today's Atmosphere

In lesson 1 & 2 we looked at how the atmosphere has changed over a long period of time and the evidence that has been used to prove that.
In this lesson we will look at the atmosphere as it is today and look at two methods for determining the composition of the atmosphere.

I teach the AQA GCSE Chemistry course, including both double (8464) and triple (8462) award, and as such most of these resources will be specific to that course, however they may also be useful for other specifications.
