I have now added a sheet explaining how this can be done at home by students themselves. This KS4 AQA Required Practical covers Density of a regular and irregular solid and liquid. It also contains the planning, carrying out and analysing of results with 9-1 graded exam style questions… It lasts approx 2 hours. The ppt carries the students through all aspects of the practical including hypothesis, variables, safety, fair testing, method, analysing results and evaluating the validity. It finishes with exam style questions individually graded to assess students. Resource includes: 30+ slide ppt to guide the students through the practical (with answers and examples) Two page student method/practical sheet that follows the slides Two page guide sheet (Required Practical Graphic Organiser worth £1.50 from my shop) based on IV Characteristics Apparatus list for technician Learning Objectives on each slide linked to AQA specification It is available in a bundle with 8 other “home use” required practicals here: https://www.tes.com/teaching-resource/nine-required-practicals-for-home-use-12461001 If you would like to see a FREE sample similar to this before you buy, the I-V Characteristics one is free here: https://www.tes.com/teaching-resource/-updated-i-v-characteristics-required-practical-planning-with-9-1-graded-questions-and-answers-12199364 If you want the FREE version of the questions only (my most downloaded resource) they are here: https://www.tes.com/teaching-resource/physics-required-practical-worksheet-revision-11791358 If you want a bundle of ALL the Physics Practicals, click here: https://www.tes.com/teaching-resource/all-physics-planning-practicals-with-graded-questions-and-answers-12227081 If you ONLY want the questions and answers, they are available as a bundle here: https://www.tes.com/teaching-resource/physics-required-practical-worksheets-with-9-1-graded-exam-style-questions-with-answers-12199346 Please comment if you have found this useful If you would like more required practical resources (or other science resources) free and paid, please check out my shop at: https://www.tes.com/teaching-resources/shop/stephenkemp193 Thank you.

This is a full lesson covering Oxidations states for AS Level. It covers calculating the oxidation state of an element in a compound or ion from the formula; writing half-equations; identifying the oxidation and reduction processes in redox reactions and combining half-equations to give an overall redox equation. It also covers more complex half equations that include H+ (in acids) or transition metals. Included is: 40+ page Power Point with explanations and examples at each stage. 4 Sets of questions and answers (including exam style questions similar to ones from the AQA past papers) A sheet with diagrams (to save time) for students to make notes on A sheet of the oxidation state rules Answers in the Power Point and Word format to allow students to self assess or “correct” their answers. A free sheet of oxidation state rules are here: https://www.tes.com/teaching-resource/oxidation-state-rules-with-examples-as-level-12412598 Other AS lessons are available: Ionisation energy:https://www.tes.com/teaching-resource/ionisation-energy-as-level-12412339 Electronic Structure:https://www.tes.com/teaching-resource/electronic-structure-orbital-configuration-in-s-p-d-as-level-12405614 TOF Spectrometer and Isotope Calcuations: https://www.tes.com/teaching-resource/mass-spectrometer-tof-and-isotope-calculations-12386980 For other resources (free and paid), please visit my shop here: https://www.tes.com/teaching-resources/shop/stephenkemp193 Please Comment if you have found this resource useful.

This lesson guides students through how to convert a circuit diagram of a series or parallel circuit into a built one. It starts with circuit symbols, then step by step it shows using photographs how circuits are built from diagrams. This resource contains: 40+ slide powerpoint with quizzes on symbols and plenary quiz on recognising series and parallel circuits along with photographs and instructions on how to build each circuit Worksheets with circuit diagrams and photographs Information sheet for learning the circuit symbols ( I designed this lesson because I and my students wasted a lot of time trying to build more complicated circuits to measure voltage and current-so hopefully time spent here will save time later in other lessons). I will be publishing more resources on electricity, but in the meantime, if you want a free animation on electricity to help click here: https://www.tes.com/teaching-resource/understanding-electricity-voltage-and-current-12450133 If you want a lesson on the main electrical models (with animations), click here: https://www.tes.com/teaching-resource/electrical-models-with-animations-12451806 For more free (and paid) resources, check out my shop at: https://www.tes.com/teaching-resources/shop/stephenkemp193 Thank you for reading this far.
