Course overview
Learners will start this term with mocks. They will complete one paper for Chemistry
After this, they will complete CTG on specific topics they found difficult during the mock. It will be up to the teacher's discretion how long they spend on these.
Once completed, they will finish the unit they started last term which was on “Energy changes” and “Chemical changes”
Energy changes; Energy changes are an important part of chemical reactions. The interaction of particles often involves transfers of energy due to the breaking and formation of bonds. Reactions in which energy is released to the surroundings are exothermic reactions, while those that take in thermal energy are endothermic. These interactions between particles can produce heating or cooling effects that are used in a range of everyday applications. Some interactions between ions in an electrolyte result in the production of electricity. Cells and batteries use these chemical reactions to provide electricity. Electricity can also be used to decompose ionic substances and is a useful means of producing elements that are too expensive to extract any other way.
Chemical changes; In this unit learners will recap the reactivity series of metals, look at how they react with different substances and gain an understanding of how this is used when extracting metals. They will look at the reactions of metals, metal oxides, metal hydroxides and metal carbonates with acids. They will learn about the pH scale and what an acid and an alkali is. They will then look at the different methods of extracting metals.
Key Concept:
Chemical & energy changes
Assessment Points:
End of unit assessment will consist of a 40 mark test
Midway assessment set by class teacher which could be an exam question
Guidance:
Learners will receive guidance in a variety of ways. These include marked assessments, reports, verbal feedback, written feedback in books, 1:1 interaction, Google Classroom and whole class feedback.
