Explain how heat is lost from the home or how heat enters the home when we don’t want it to. State ways we can reduce heat transfer in the home. Explain how cavity walls and double glazing reduce heat transfer

To explain radiation using the particle model. To explain in detail how energy is transferred by radiation linking ideas from particle model and energy i.e. kinetic energy of particles. To relate the radiation properties of shiny, matt, dark light surfaces.

To describe materials as insulators or conductors and give examples. To make a prediction with reasons with respect to best insulating material. To describe heating and cooling in terms of heat energy being transferred to or from surroundings.

Learning Objectives ✤ State the adverse effect of Global Dimming and discuss why these pollutants are of global concern ✤ Relate this to particle theory and light diffraction/reflection. Settler: Starter: https://quizlet.com/57699307/aqa-c143-hydrocarbon-fuels-flash-cards/ Demonstration: Practical: Main 1: See ppt. Main 2: AFL: Homework Exploratorium activity on website. https://www.youtube.com/watch?v=2JmrmwIyhAE

Learning Objectives ✤ State the adverse effect of Carbon Monoxide on health and discuss why this pollutant is of global concern. ✤ Explain why carbon monoxide detectors are used. Settler: Starter: Demonstration: https://www.youtube.com/watch?v=lMnaLKlVXxo Practical: Main 1: See worksheet. Main 2: Balancing equations activity in ppt. AFL: Homework Produce a warning poster on the dangers of improper use of gas fires in the home. A good poster will meet the learning objectives above and include explanation of any keywords used.. - examples on website

Learning Objectives ✤ State the adverse effect of these common pollutants on buildings and why these pollutants are of global concern ✤ Relate the effects of acid rain to sedimentary rocks.

Learning Objectives ✤ State the adverse effect of Global Warming and discuss why these pollutants are of global concern ✤ State that carbon dioxide is a greenhouse gases and explain how it may contribute to climate change. Settler: Starter: Demonstration:

Learning Objectives ✤ To plan an investigation into the effect of volume of air on the time it takes for a candle to go out. ✤ To carry out an investigation Settler: https://www.youtube.com/watch?v=hwU3YL_SD70 Starter: Use common mistakes ppt. Demonstration: Practical: Main 1: This is the levelled task for this topic. We will be used to level along UK national curriculum levels you ability to carry out an investigation. The assessment is looking mostly for your ability to make links between the topics and explain both verbally and using diagrams. The levels available will range from a 3c (lowest) to a 7a (highest). If pupils have already achieved a 7c or above in the previous levelled practical they will be given the opportunity to use the GCSE criteria, these have much more criteria to be completed but will allow pupils to achieve grades rating from a FAIL to an A*.

Learning Objectives ✤ Name the common pollutants in the air ✤ State the source of each of these pollutants. ✤ Describe and explain the presence of oxides of nitrogen in car engines and their catalytic removal. Settler: Some great combustion videos: The essential element Starter: Demonstration: https://www.youtube.com/watch?v=Ubop-51dJjg Practical: Main 1: Main 2: AFL: Have pupils take poll on the website and discuss Homework Read "A students guide to Global Climate Change" Think about this question.. Is carbon dioxide always a bad thing?

Learning Objectives ✤ Understand that liquids can be separated by distillation according to their boiling points. ✤ Describe the separation of oxygen and nitrogen from liquid air by fractional distillation Settler: Starter: Demonstration: Can show the oxygen in the jar demo with the water rising then ask the kids to explain why this demo does not show that the air is 20% oxygen as they are often taught but is due to pressure differences instead. Practical: Main 1: Use ppt. Main 2: AFL: Most pupils will struggle with the concept but can be used as an introduction to year 10 - use questions from year 10 textbook to assess. Homework

Learning Objectives ✤ State the composition of clean, dry air ✤ Explain the changes in the Earth that led to oceans forming. ✤ Relate the Earths early atmosphere with that of Mars or Venus today. ✤ Explain the changes in the Earths atmosphere today.
