This is the first lesson in the topic ‘The Environment and the Atmosphere’ This lesson is delivered over YouTube but has some accompanying resources. https://www.youtube.com/watch?v=jtfJMOIoPFg In this lesson I discuss some theories of what the Earth and its atmosphere may have been like in the past, and set a task for students to create a storyboard of how the atmosphere has changed over time. The review work set in this lesson can be found at https://www.youtube.com/watch?v=dF81ReGLz4w&list=PLRQqpdTTanY_8L_9hEq5CnpU_rNoacQlP&index=3&t=198s Links mentioned in the video:- GCSE BBC Bitesize My Favourite one Primoridal Soup These can all be found at https://www.youtube.com/playlist?list=PLRQqpdTTanY9189wmlA5TIW2_nTaWl-Fj 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.

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 sets the students off on a research task to find out about the BIG five pollutants in our atmosphere and where the come from.

These are the resources for a unit on types of electricity, condutors, insulators, circuits, series, parallel, fruit batteries, static electricity, electromagnets, magnets, QM stands for Quality Mark which is a levelled formative assessment based on scientific skills. In the powerpoints I use: -Yellow boxes- to show the students what to write in their books. - Blue boxes- for tasks that the students should do. I do not own all of the content in these resources, no copyright is intended, any offending resources will be removed.
