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. This lesson is delivered over YouTube but has some accompanying resources. https://www.youtube.com/watch?v=VRNodyQNQoE&list=PLRQqpdTTanY_8L_9hEq5CnpU_rNoacQlP&index=5 A follow up video of student questions can be found at https://www.youtube.com/watch?v=ycBCQDUjoA4&list=PLRQqpdTTanY_8L_9hEq5CnpU_rNoacQlP&index=6 The review of work set in this lesson can be found at https://www.youtube.com/watch?v=fMjofcBkPB8&list=PLRQqpdTTanY_8L_9hEq5CnpU_rNoacQlP&index=7 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.

Last lesson we looked at at the atmosphere as it is today and looked at two methods for determining the composition of the atmosphere. In this lesson we will see and learn how to do the calculations that scientists use to determine the volumes of gases. This is a simplified version of these types of calculations as my students had not yet come across moles or relative formula mass.

Last lesson we looked at the carbon cycle i.e. how carbon is reused and recycled in our atmosphere and planet. In this lesson we will learn about Greenhouses Gases and where they come from.

Last lesson we looked at Greenhouses Gases and where they come from. In this lesson we will learn about how those greenhouse gases contribute to the Greenhouse Effect and Global Warming This lesson is delivered over YouTube but has some accompanying resources. https://www.youtube.com/watch?v=NDQEJuePIfw&list=PLRQqpdTTanY_8L_9hEq5CnpU_rNoacQlP&index=14 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.
