The 'Limestone and Building Materials' topic looks at uses of limestone and reactions of the carbonates. Lesson objectives: Most students will be able to: Recap uses of limestone See how metal carbonates react similarly to limestone, when they are heated, and the products that they make. Write word equations to describe thermal decomposition in a metal carbonate. Some students should also be able to: Detail thermal decomposition of metal carbonates, in a balanced symbol equation. Resources included: 1.Worksheet to explain practical lesson with questions included. 2. PowerPoint with starter recapping uses of limestone, method to explain practical, with expected results provided. Then a plenary to test understanding of word and symbol equations.

The 'Limestone and Building Materials' topic looks at uses of limestone and reactions of the carbonates. Lesson objectives: To understand the differences between cement, concrete and mortar. To test the strength of concrete Resources included: 1.Starter on ppt but if required this could be an alternative- Revision of limestone cycle. 2-5. Practical worksheets that can be given to students of different abilities, investigate how to make concrete and how the strength can change depending on the ratio of sand, cement and aggregate. Could be extended to include reinforced concrete. 6. Alternative to practical also involves finding out how glass is made. 7. Video, about 1min 30sec on how concrete strength is tested in a lab. Has cool backing music! 8. Possible homework- double sided worksheet, recaps previous work. 9. PowerPoint linking the main parts of the lesson together, has starter and plenary.

Introduction to IGCSE Chemistry and the first lesson in the topic 'States of Matter'. Dealing with changes of state between solids, liquids and gases and demonstrating diffusion with a choice of experiments depending on the level of student understanding and equipment available to you. Objectives: Can you describe the interconversions of solids, liquids & gases? (C) Can you explain the idea of diffusion with a practical example? (B) Can you apply the idea of diffusion to fully explain an example within both liquids & gases? (A/A*) Students expected to formulate their own ideas about diffusion and draw on knowledge from KS3.

The second lesson in 'The Fundamental Ideas in Chemistry' topic looking at how electrons are arranged in shells. Lesson objectives: -Understand that elements in the same group in the periodic table have the same number of electrons in their highest energy level (outer electrons) and this gives them similar chemical properties. -Know that elements in Group 0 of the periodic table are called the noble gases. They are unreactive because their atoms have stable arrangements of electrons. Resources included: x1 Powerpoint starter on identification of element from atomic number. x1 PowerPoint with lesson objectives from AQA with main content of lesson and plenary. x 4 worksheets, all based on understanding electron arrangement, chose which one depending on your students. x2 teaching aid/animation good to use with interactive whiteboard or mouse (.swf files need Adobe Flash Player)

Students investigate surface area though a range of practical applications. Suitable for GCSE or an able year 9 group. Objectives What is surface area and how is it calculated? (Grade C) Can you explain how surface area affects the rate of a reaction? (Grade C) Can you explain why surface area affects the rate of a reaction? (Grade B) Can you apply this explanation to a reaction between limestone chips and acid? (Grade A)
