The third lesson in 'The Fundamental Ideas in Chemistry' topic looking at how atoms can join together using elections, how to show them as chemical reactions and how to ensure they are balanced. Lesson objectives: -When elements react, their atoms join with other atoms to form compounds. This involves giving, taking or sharing electrons to form ions or molecules. -Compounds formed from metals and non-metals consist of ions. Compounds formed from only non-metals consist of molecules. -In molecules the atoms are held together by covalent bonds. -Chemical reactions can be represented by word equations or by symbol equations. -No atoms are lost or made during a chemical reaction so the mass of the products equals the mass of the reactants. Resources included: 1. Powerpoint with starter reviewing work on electron arrangement and testing current student understanding of chemical reactions. Explanation of molecules, ions and simple bonding before going into balanced equations. Some equations to balance on the ppt. and links to websites that do the same thing. 2. Quick true or false quiz to use as plenary. 3. Worksheet to practice balancing equations.

The 'Limestone and Building Materials' topic looks at uses of limestone and reactions of the carbonates. Lesson objectives: Can you state the general equation for the reaction between a metal carbonate and acid? Can you construct equations (word and symbol) for reactions studied? Resources included: 1. Alternative lesson starter on limestone cycle, good for revision also. 2. Help sheet for students to understand the products formed when acids react with carbonates, should be used after practical. 3. Essential homework sheet. The social and environmental impacts of building factories often comes up in exam papers. This has an assessment criteria sheet that can be used in the following lesson for students to self assess. 4. PowerPoint, main part of the lesson with starter, theory, practical activity on reacting acids with carbonate, then focus on reactions, includes plenary. 5. Alternative plenary activity, revision as this would be last lesson in the topic. Taboo- students have to guess the word without using any words on the list.

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 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)
