IGCSE Edexcel Chemistry solubility curves and solubility practical. Solubility definition and units of solubility, with solubility exam questions. Lesson objectives: Define key terms relating to solubility, Define solubility and Investigate the solubility of a solid in water at a specific temperature. All the slides in this lesson are fully animated and include answers to every mini plenary question and exam question. The breakdown of the slides is as follows: Slide 1 - Title and 5-minute starter. The starter is a grid of four questions entitled ‘last week, last lesson, today’s learning and future learning’. Use this generic slide for all of your lessons by simply changing the questions and the answers each time. Slide 2 - Lesson objectives (see above) Slide 3 – matching activity for the key terms linking to solubility, e.g. solvent, solute, solubility, etc. Slides 4 – 5 – printable copies of slide 3 for students Slide 6 – diagram introduction to practical Slide 7 – method for practical (step-by-step) Slide 8 – results grid where students will record their data Slide 9 – introduction to solubility curves Slide 10 - If you had 180 g of KNO3 at 80℃, it would look like the first photo. However, if you cool the solution down to 40℃, it would look like the second photo, as the mass of salt which cannot dissolve at the lower temperature crystallises out of solution Slides 11 – 13 – series of worked examples of solubility curve problems. Answers animate on to the screen as you click (don’t worry!) Slide 14 – data for students to draw their own solubility curve (graph paper not provided) Slide 15 - WAGOLL Slide 16 – ALT (Applied learning time). Questions that require students to interpret the solubility they have drawn to answer. If they were not able to draw it, print slide 15 for them and have them use it to answer the questions. Slide 17 – Answers Slide 18 – Exam question slide Slide 19 – mark scheme If you have a positive experience with the resource please leave a positive review!

Potable water GCSE Chemistry lesson AQA combined science, including difference between potable water and pure water, treatment of sea water and freshwater to produce potable water, with questions and answers throughout. The lesson objectives are as follows: Distinguish between potable water and pure water, describe the differences in treatment of ground water and salty water and** justify** the steps used to produce potable water. The slides are fully animated and include answers to every mini plenary question and exam question. The breakdown of the slides is as follows: Slide 1 - Title and 5-minute starter. The starter is a grid of four questions entitled ‘last week, last lesson, today’s learning and future learning’. Use this generic slide for all of your lessons by simply changing the questions and the answers each time. Slide 2 - Lesson objectives (see above) Slide 3 - Introduction to the importance of water and what constitutes safe, drinking water Slide 4 - Definition of potable water presented Slide 5 - Concept of pure water introduced (Pure water contains water molecules and no other dissolved substances). A photo of a bottle of Evian water is used as the discussion point: Is this bottle of mineral water pure? Answer animates onto screen: No, as it contains other dissolved ions, e.g. potassium, nitrates and sodium Slide 6 - Mini plenary. 3 questions testing pupils’ understanding of the difference between potable water and pure water. Answers animate onto the screen Slide 7 - This slide introduces the question: How is potable water produced in the UK? Slide 8 - Steps involved to produce potable water from freshwater, including selection of appropriate source of freshwater, definition of freshwater, filter beds and sterilising with chlorine, ozone or UV Slide 9 - Parched photo of Sahara desert to introduce the question: How is potable water obtained in countries like Saudi Arabia where there are no rivers or lakes? Slide 10 - Steps involved to produce potable water from seawater, including desalination, distillation and reverse osmosis. Slide 11 - Mini plenary. 4 questions testing pupils’ understanding of the steps involved in producing potable water from freshwater and seawater. Answers animate onto the screen Slide 12-16 - Exam questions on potable water with answers animating onto the screen from the mark scheme. The last question is worth four marks, which could be useful for extended writing Follow me on Twitter https://twitter.com/MC_Afrique If you have a positive experience with this resource please leave a positive review!

Carbon cycle diagram, carbon cycle steps and carbon cycle definition. GCSE Biology Lesson objectives: Explain the importance of carbon to living organisms, explain how the carbon cycle returns carbon from organisms to the atmosphere and explain the role of microorganisms in cycling carbon through ecosystems. The slides are fully animated and include answers to every mini plenary question and exam question. The breakdown of the slides is as follows: Slide 1 - Title and 5-minute starter. The starter is a grid of four questions entitled ‘last week, last lesson, today’s learning and future learning’. Use this generic slide for all of your lessons by simply changing the questions and the answers each time. Slide 2 - Lesson objectives (see above) Slide 3 - Introduction to plants as producers, including photosynthesis and brief explanation of the food chain in relation to the compounds made by plants Slide 4 – Addressing the question: Why is carbon important to living organisms? Slide 5 - Mini plenary. Three questions of increasing difficulty to test learning so far. Answers animate onto the screen. Slide 6 - Introduction to the carbon cycle definition Slide 7 – Detailed, labelled pencil-drawing of the carbon cycle. Pupils will copy this into their book. Each arrow of the cycle is numbered and the numbers animate onto the screen in sequence in a prescribed order. This serves as a guide for pupils to know the sequence in which they should copy the diagram. It will also allow you to explain each stage of the cycle. Please note ‘carbon in animals’ appears twice as primary consumers eat plants and secondary consumers eat the primary consumers Slide 8 - Mini plenary. Four questions of increasing difficulty to test learning so far. Answers animate onto the screen. Slide 9 – Introduction to decomposers and what their role is in the carbon cycle Slide 10 -Explanation of how microorganisms contribute positively to the carbon cycle Slide 11 - Mini plenary. Two questions of increasing difficulty to test learning so far. Answers animate onto the screen. Slide 12 – ALT (Applied Learning Time). 6-mark exam question. Mark scheme animates onto the screen Slide 13 – Plenary.
