KS4 Curriculum Guide - Year 10 Chemistry
Term 1C4 Chemical Changes 
Understanding of chemical changes began when people began experimenting with chemical reactions in a systematic way and organising their results logically. Knowing about these different chemical changes meant that scientists could begin to predict exactly what new substances would be formed and use this knowledge to develop a wide range of different materials and processes. It also helped biochemists to understand the complex reactions that take place in living organisms. The extraction of important resources from the Earth makes use of the way that some elements and compounds react with each other and how easily they can be ‘pulled apart’.
Assessment: There will be an mid term written or practical task that will be peer or self assessed plus an end of term assessment using past exam questions to be completed under exam conditions and assessed by the teacher.Key Words and Terms
 
Term 2C4 Electrolysis & C5 Energy Changes 
Students will consider that 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. Some interactions between ions in an electrolyte result in the production of 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.

Term 3C6 Rates of chemical change & C8 Chemical analysis  
Students will investigate how Chemical reactions can occur at vastly different rates. Many variables that can be manipulated in order to speed them up or slow them down. Chemical reactions may also be reversible and therefore the effect of different variables needs to be established in order to identify how to maximise the yield of desired product. Analysts have developed a range of qualitative tests to detect specific chemicals. The tests are based on reactions that produce a gas with distinctive properties, or a colour change or an insoluble solid that appears as a precipitate. Instrumental methods provide fast, sensitive and accurate means of analysing chemicals, and are particularly useful when the amount of chemical being analysed is small. Forensic scientists and drug control scientists rely on such instrumental methods in their work.

Term 4C3 Quantitative Chemistry 
In this topic we will look at how Chemists use quantitative analysis to determine the formulae of compounds and the equations for reactions. Identifying different types of chemical reaction allows chemists to make sense of how different chemicals react together, to establish patterns and to make predictions about the behaviour of other chemicals.

Term 5Revision  
Pupils will review all learning from Year 9 and 10 in science to complete their end of year exams. This will entail a lot of intensive revision time and personal analysis before returning in Year 11.
Assessment: The 3 exams will be a set of past exam questions with around 100 marks available in each paper at either a Higher or a Foundation level. They should aim to answer one mark per minute. The questions will be a mixture of short answer and long answer questions, each worth 1-6 marks. Pupils we be expected to recall knowledge, describe and explain theories, complete calculations using memorised equations and apply their understanding to previously unknown data or scenarios.Key Words and Terms
