This resource contains a 30+ page Power Point (and pdf ) to guide students through the new Hazard symbols, their names, hazards and controls (precautions) that are needed in each case. Students have three tasks, a sorting activity, a memory activity and a longer activity which aims for them to think about the hazards, risks and more importantly the controls that need to be put into place to perform the practical safely. The activity contains: Four “fake” chemical Hazcard sheets Four Scenarios to challenge their thinking Posters of the new Hazard symbols with information on each Miniplenary to test knowledge gained. The free poster of the new hazard symbols can be found here: https://www.tes.com/teaching-resource/new-hazard-symbols-meanings-with-examples-for-lab-safety-12266717 Please check out my shop for more free (and paid) resources: https://www.tes.com/teaching-resources/shop/stephenkemp193 Thank you

This full lesson resource helps students to balance full and half equations and apply state symbols with 9-1 graded exam style plenary questions (F and H). It lasts about 1.5 hours. This resource is linked to the AQA specification and has 9-1 graded learning objectives linked to the content. (Update: Now included at no extra cost is my Empirical Formula from Models lesson) It includes: 33 page ppt which explains using a balancing full equations using the circle the formula method, to avoid the misconception to change the formula (see https://twitter.com/MrTSci409/status/1116405433684713472) 3 Helpsheets (Full/Half/State symbols) for students to refer to when completing the questions 46 Equations to balance (30 full and 16 half) with ANSWERS for students to self/peer assess All equations are taken from the AQA Specification (let me know if I’ve missed any out!) Plenary questions (F and H) graded with answers A gratuitous use of colour to help understand how and why equations are balanced. For a free help sheet on how to balance equations from this resource, click here: https://www.tes.com/teaching-resource/balancing-equations-help-sheet-12233425 The Empirical formula from Models lesson details are: This is a full lesson lasting about 1 hour. It includes a Power Point which covers ratios, simplifying formulas into empirical formulas and understanding models of ions. It includes a starter, seven white board practice questions, seventeen question sheet on simplifying formulas, seven question sheet on models and a plenary. It’s a lesson designed to cover an often neglected part of the course… I’ve also included a Power Point with all the models and others I’ve used in the lesson in case you want to design a few more of your own… A shortened version of this is available here: https://www.tes.com/teaching-resource/empirical-formula-from-models-12238973 For more resources (free and paid), please visit: https://www.tes.com/teaching-resources/shop/stephenkemp193 A hope you find this resource helpful.

This Chemistry resource is aimed at KS3 (or lower ability KS4). It last an hour approximately and has 4 group challenges and a whole class challenge at the end. It includes audio instructions from the Periodic Table Master who challenges the students to solve his fiendish clues and try to escape where none have done before. Please use this resource responsibly as it’s a bit scary. If you want a less scary version try: https://www.tes.com/teaching-resource/fun-periodic-table-and-elements-lesson-12194324 It includes: Lesson Plan with ideas for how to increase the atmosphere in the room (it doesn’t need a lab) Clues for students to find elements, their symbols and their position on the Periodic Table in terms of periods and groups. It also uses their knowledge of reactivity of groups 1 and 7 for solving some of the clues. Sound of the voice of the Periodic Table master to increase the realism. An evaluation at the end to judge which parts of the escape room (curriculum) they found easy/hard. Please comment. I hope you find this resource useful. Thank You.

This resource contains keywords, images and definitions (see below for all 60 keywords covered). It is aimed at KS4, but can be used with upper KS3. The resource can be used as a matching activity, a booklet for revision or display (more uses described below). It can be used in several ways: As a whole class activity: The Power Point version is animated so that it puts the image on first, followed by the keyword, then the definition. In this way, students can be shown the image and asked what the keyword is, then are asked what the definition is. The Interactive Power Point has all the keywords linked to the slide with that definition. It also contains a back to the previous slide button so that you can back to the word you were discussing. The Interactive Keyword Power Point at beginning has all the keywords on the second slide. Click to link to that slide, then click the Home button to go back-Use when referring to certain words that students have difficulty with. As a display around the room. Printed smaller and given to the students as a keyword booklet or Graphic Organiser to revise from. Memory game: Printed smaller and cut out, turned over and the students turn a card over and ask the other students in their group to give the definition when given the word, or vice versa. Cut the titles off and the image, place them all around the room, give the student one piece and ask them to find the other two parts tjhat go with it. The presentation has all the keywords in order of when they are mentioned in the AQA Specification. The Keywords are: Atom, Element, Chemical Symbol, Periodic Table, Compound, Chemical Reaction, Energy Change, Chemically combine, Proportion, Formula, Word Equations, Symbol Equations, Balanced, Ion, Half Equation, Ionic Equation, Separation, Filtration, Crystallisation, Distillation, Fractional Distillation, Chromatography, Purification, Chemical Properties, Model, Electron, Plum Pudding Model, Alpha Particle Scattering Experiment, Nucleus, Nuclear Model, Orbit, Protons, Neutrons, Charge, Relative, Isotopes, Atomic Mass, Nanometres, Percentage Abundance, Energy Levels/Shells, Electronic Structure, Groups, periods, Atomic Weight, Metals, Mendeleev’s Periodic table, Non-metals, Noble gases/Group 0, Trend/Pattern, Alkali Metals/Group 1, Halogens/Group 7, Molecule, Displacement, Aqueous, Salt, Solution, Transition Metals, Density, Hardness and Reactivity. *New Keywords added: Atomic Number, Mixtures, Physical properties, Scattering and Shielding Please comment with any suggestions for improvements or other ideas for resources. I hope you find this resource useful.
