KS3

Key Stage Three Curriculum Overview

Y9	NAME OF TOPIC	KEY CONTENT OF THE TOPIC	ASSESSMENT POINTS
HT 1	Foundation Chemistry Acids and Alkalis	The main aim of the first term of study is to foster good habits in the student’s approach to carrying out practical work and the subsequent reporting. Students are re-introduced to writing chemical equations. This was first encountered in Y8. Through the study of acid reactions, students learn to write balanced symbol equations for the reactions they encounter. They are also encouraged to consider the health and safety implications for the experiments they carry out. Simple risk assessments should be prepared. Acid + Metal à Salt + hydrogen Acid + Base à salt + water Acid + Alkali à salt + water Acid + carbonate à salt + water + CO2 Students should: Know the general acid reaction equations Be able to predict the salt formed Be able to identify hydrogen and carbon dioxide gases. Write word equations (minimum) Write balanced symbol equations (extension) Be aware of the use of indicators and their colours Be able to describe and carry out a simple neutralisation using indicator Be able to carry out a simple titration. Be able to prepare and then isolate a soluble salt e.g CuO + sulfuric acid	Use Chemsheets resources Naming substances Word equations Balanced equations Chemsheets (KS3 content)
HT 2	Acids and Alkalis Precipitation Reactions Separation techniques	Acid Rain task Students should: Study reactions of metal ions and hydroxide Be able to describe products Write balanced ionic equations Students should revise the separation techniques encountered in Y7 and 8: Filtration Simple distillation Chromatography	Reactions of acids 1-4 Acids and bases Test on reactions of acids Chemsheets (KS3 content) Separating mixtures END OF TERM EXAM
HT 3	Atomic Structure Periodic table	GCSE Unit 1 Students learn about the development of the model of the Atom, ending on the Bohr model we use today. They are familiar with using scientific models (e.g. particle model of matter). What is an Atom? Development of model Subatomic particles Size and mass Ar Electron arrangement Elements definition Elements react to make compounds. Naming compounds Writing formulae Writing equations
HT 4	Periodic Table Continued	Mixtures definition and separation techniques including Chromatography. Filtration Evaporation Distillation Fractional Distillation Development of the PT Trends in the PT Metals/Non-metals Group 1 Group 7 Group 0 TM’s
HT 5	The Atmosphere	GCSE syllabus topic 9 Modern atmosphere vs early atmosphere. Detail of how water and CO2 went down Why did O2 increase
		YEAR 9 END OF YEAR ASSESSMENT
HT 6		Greenhouse effect CO2 CH4 H2O are greenhouse gases. What is the Greenhouse effect and how does it arise. Human activities and the Greenhouse effect Climate Change Carbon Footprint Pollutants Pollutants from burning fossil fuels Effects and properties of pollutants	Assessment of GCSE topics covered so far.
