Once this work has been checked, pupils are then shown how to draw a dot and cross diagram of a double bond and triple bond (oxygen molecule and nitrogen molecule), it may be beneficial for pupils to draw these diagrams in their books for future reference. The lesson now focuses on some of the properties of simple covalent molecules, then pupils will be asked to draw a dot and cross diagram to show the structure of water, methane and ammonia. Once this task is complete, students can assess their work using the answers provided on the PowerPoint presentation.

Students will then work their way through a set of questions using this calculation, for latter questions students will need to rearrange the equation. This work can then be assessed using the answers provided in the PowerPoint presentation. The next part of the lesson focuses on calculating the masses of gaseous reactants and products, firstly students are shown a worked example. The next task is for pupils to watch a video, using which they should answer a set of questions. Once this task has been completed students shoudl mark their work using the answers provided. Using the formula they have learnt whilst watching the video, they should now complete a set of questions on a specific chemical reaction - this required students to calculate the volume of gases produced or the mass of a reactant needed to produce a certain amount of a gas product.

For more lessons designed to meet specification points for the NEW AQA Trilogy specifications for Biology, Chemistry and Physics please see my shop: https://www.tes.com/teaching-resources/shop/SWiftScience The lesson starts with a Think > Pair > Share task for pupils to consider the properties of gold, pupils can list them down and then share their ideas with the class. The property of gold being very soft is not always useful, especially when it is being used to make jewelery and so it is often mixed with another metal (e.g. platinum) to make it stronger. The concept of an ‘alloy’ is then introduced, as well as a definition and an explanation as to why alloys are useful. Some useful properties of alloys are listed - malleable, durable, strong, flexible - pupils need to come up with a a definition for each of these properties. Once this task is complete students can self-assess their work using the mark scheme provided. The next task for pupils to complete is ‘Who’s right for the job?’ - students will be given information on the properties of different metals, as well as a list of alloys needed for different jobs - used in jewelery/used to make airplane bodies. Students need to select the correct metals to make the alloys required, their work can be self-assessed using the mark scheme provided. The next part of the lesson focuses on iron alloys specifically, firstly students will watch a video on iron alloys and will need to answer a set of questions - this work can then be self-assessed using the answers provided. The last task for pupils to complete is a table whereby students need summarise how carbon content affects steel and it’s properties, this work can also be self-assessed using the mark scheme provided.

This lesson is designed for the Activate KS3 Science Course, specifically Year 7 C3 ’Reactions’. For more lessons designed for KS3 and KS4 please visit my shop at: https://www.tes.com/teaching-resources/shop/SWiftScience. Students will firstly be shown a demonstration of magnesium being burnt in air, students are asked to predict whether they think the mass of the product will increase, decrease or stay the same. Students are asked to explain their prediction. The demonstration is then carried out, students should record in their books the mass of the magnesium before burning and then the mass of the magnesium oxide after burning, from this they can deduce the mass of the oxygen needed to burn the magnesium. Students can then check their predictions to see if they were correct or not. Now, students can summarise what they have learned by completing a ‘fill-in-the-blank’ task which is a definition for the ‘conservation of mass’ in chemical reactions. This task can be self-assessed against the mark scheme provided. Students will now also complete a ‘Quick Check’ task where they are asked come questions to test their knowledge of what they have learned so far, this work can also be marked against the mark scheme provided. Students will not complete a match-up task, students are asked to complete the sentences by matching the correct phrases together. This helps students to explore the idea of the law of the conservation of mass, considering how this applies to reactions involving solids, liquids and gases. Again, the mark scheme for this task is included for students to check and correct their work. The latter part of the lesson is on balancing equations, students are firstly introduced to the process by which students should balance an equation, demonstrated by the example of magnesium + oxygen -> magnesium oxide. A few more examples are used to talk students through the process, then students will complete a step-by-step worksheet which introduces them to balancing equations at a basic level. The mark scheme for this task is included in the PowerPoint for students to self-assess their work. The plenary task requires students to complete a 3-2-1 reduction of the lesson, to include 3 facts 2 key words and 1 question to test their peers knowledge of what was learned this lesson.

For more lessons designed to meet specification points for the NEW AQA Trilogy specifications for Biology, Chemistry and Physics please see my shop: https://www.tes.com/teaching-resources/shop/SWiftScience The lessons starts with looking at the way in which we use models to represent the structure of different compounds, models include the 3D ball and stick model, 2D ball and stick model, dot and cross diagrams and displayed formula showing bonds. Pupils are reminded of the limitations of some of these models, this is something they should be able to recount. Pupils are now shown a diagram to show how intermolecular forces act between simple covalent molecules, pupils should be able to explain the difference between the strong covalent bonds between atoms but the weak intermolecular forces between molecules and how this relates to the the low melting and boiling points of simple covalent molecules. The next part of the lesson is going to focus on giant covalent structures, firstly pupils will watch a video and answer a set of questions. Their work can be self-assess using the answers provided on the PowerPoint presentation. Students are then introduced to the three main covalent structures - diamond, graphite and silicon dioxide. Students will be given a set of information on these structures which they will need to use to complete their worksheet on giant covalent structures. To assess their knowledge of this topic there is a set of ‘quick check’ questions, pupils of a higher ability may want to complete these questions in the back of their books without discussing with others. The work can be assessed using the mark scheme provided. The last part of the lesson focuses on fullerenes and graphene - two other giant covalent structures with unique properties. Students are firstly introduced to the structure and uses of these compounds before watching a video and answering questions about them. The work from this task can be self or peer assessed using the answers provided. The plenary task is for pupils to pretend they are a scientist researching the use of nanotubes, fullerenes and grapehene, they need to come up two ideas of how these materials can be used in future technologies.
