Whole scheme of work for microbes year 8 biology.

Be able to describe what happens to particles at a melting point for a substance Be able to draw particle diagrams for boiling and melting Be able to draw number lines for states of a substance.

Be able to use the celsius scale to describe temperatures. (including relating to the MP and BP of water) Be able to convert to the Kelvin scale and define the meaning of Absolute zero. Be able to convert to Fahrenheit and visa versa

To understand that the rate of heat transfer rely on several things;, temperature difference, area of surface and surface type To be able to define U value as the property of a surface to transfer heat. Calculate energy used using U values

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.

To describe hot objects getting colder in terms of heat going out of the object To describe hot objects getting colder in terms of heat energy being transferred to surroundings To describe the relationship between energy transferred and increase in temperature

An explanation of how particle equations and molecular formula work.

A lesson around the suitability of metals to their use.

A selection of data sheets for environmental chemistry for iGCSE.

A selection of pollution related powerpoint.

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 ✤ 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.

Learning Objectives Be able to describe the rock cycle as continuous process that takes place over millions of years. Relate the rock cycle as a type of recycling Revise the whole rock cycle

Learning Objectives Be able to name some metamorphic rocks Be able to describe how metamorphic rocks are formed Settler: Starter: Test knowledge from previous lesson. Demonstration: Practical: Main 1: See lesson sheet Main 2: AFL: Splat in lesson sheet Homework

Learning Objectives Be able to name some sedimentary rocks Explain the processes of weathering, transportation, deposition, sedimentation, cementation Use particle diagrams to explain cementation. Settler: Starter: Demonstration: Demonstration of sedimentary rock sandwich and metamorphic toastie You can do the transportation pipe demo but it isn't very good. Practical: Main 1: Main 2: EITHER: Pupils descibe the sandwich model and explain how it is different. We could compare each others answers to see wether we have learned this OR: Pupils undertake construction company exercise 15 minutes and 5 minutes of discussion at the end. Need to address issues with the vocabulary, many misconceptions come from geography. about weathering and erosion. AFL: Homework Metamorphic rocks worksheet

Learning Objectives To describe the three types of weathering, Biological, physical and chemical. To be able to give examples of all three types of weathering. To link the weathering process to the landscape. Use particle diagrams to explain weathering Settler: Starter: Demonstration/Main 1: Draw diagrams to represent the three types of weathering on the board if you are not confident use the textbook. Pupils need to be able to use particle diagrams - in this case particle means rock pieces of any size. Practical: Show the frozen rock breaking demo as an example of freeze thaw. Main 2: Link to the landscapes of Qatar, erratics etc. AFL: Show photos of different types of weathering and ask pupils to identify them
