This resource explains how to write the electronic configuration of the first 36 elements in terms of their shells, sub shell and orbitals. It covers the AQA syllabus, but can be used with others. It contains a 30+ page Power Point which explains how electrons fill up the lowest energy levels first, how electrons prefer to stay unpaired and the rather tricky transition metal 4s/3d energy levels. It explains how to write the configuration for neutral atoms as well as ions and contains a page of questions, based around exam questions from AQA. Questions have comments from the examiners report to say how difficult students in the exam found this type of question. It also contains: Periodic Table with all configurations Student sheet with diagrams on for students to add notes to (or cut out and stick in diagrams) Help sheet to practice configuration Question sheet with answers provided on the Power Point Homework/Extra Questions sheet to challenge the most able An animated slide that shows all 36 configurations on an energy level diagram and position on the Periodic table.

This updated Biology resource now has individual 9-1 graded exam style questions to assess students levels. It is used with KS4 and is designed to ask questions on Working Scientifically and the Maths calculations that are involved. These exam style questions with model answers are adapted from AQA past papers. They are normally used post practical as assessment / revision / homework, but can be used during as well or a cover lesson. This contains all the Required Practicals in Biology in one place: Osmosis, Decay, Enzymes, Field Investigations, Food Tests, Microbiology, Photosynthesis, Plant Response and Reaction Times. It also includes the Required Practical Graphic Orgainser helpsheet (worth £1) that will help the students answer the questions in these resources. Each required practical resource comes as a 5 Power Point slide to project in lessons and a PDF version for printing. It has two sheets of questions and two sheets of answers allowing for students to self or peer assess. On the top right hand corner of the sheet the students can identify areas where they need to improve so that teachers can easily see which section they are having trouble with. Each sheet assesses students skills including interpreting the data, calculations, remembering the Health and Safety and suggesting ways of improving the experiment. Key concepts covered are types of error and rarer ones such as validity, reproducibility and repeatability. Each question slide has Blooms Style Learning Objectives for whole class focused learning.

Update: I have improved the graphics on this since it was made a few years ago. This powerpoint is aimed at KS4 (and higher ability KS3) and helps students to understand what is happening to the ions in solution. It shows sodium ions and chloride ions moving to the electrodes, gaining and losing electrons to become atoms and explaining reduction and oxidation.

This KS4 resource contains worksheet questions (and answers) for all the Physics Required Practicals with each individual exam style 9-1 graded questions. It employs a lot of Maths, AQA working scientifically and AQA style exam questions with model answers. It is normally used at the end of the practical as a test/check of the students understanding, but can also be used as a revision/homework activity. It can also be used as a cover lesson (with answers). Students can also peer/self assess with the answer sheets and also indicate which part they found most difficult on the top right of the paper so that the teacher can flick through and see what needs covering again. It contains: Specific Heat Capacity, Thermal insulation, Resistance, I-V characteristics, Density. Light, Force and Extension, Acceleration, Waves in a solid and Waves in a liquid and Radiation and Absorption.

This is a resource which uses the new up to date Hazard Symbols. Each sheet has the name of each hazard symbol, the symbol itself, a description of the Hazard, an example of which chemical has that hazard and an image to help them remember. This will help with Lab safety. This is part of a full lesson where students are taught how to use hazard symbols and hazcards to plan a safe practical: https://www.tes.com/teaching-resource/planning-safe-practicals-using-hazcards-12407118 Please feel free to visit my shop which contains more free (and paid) resources: https://www.tes.com/teaching-resources/shop/stephenkemp193 Thank you.

This resource is a booklet with lists of misconceptions, strategies for overcoming them, and quizzes for ascertaining main misconceptions in Forces, Electricity etc. Update: Want to test how many Christmas misconceptions your students have? Try this new free quiz here: https://www.tes.com/teaching-resource/christmas-quiz-free-misconceptions-12448241 It is research based, but written in a practical way and focuses on the use of models, analogies, CASE, interviewing and other strategies. The most useful part I believe is the lists of misconceptions and a comprehensive index of keywords to help you find the common misconception for that topic/keyword. Thank you for making it is one of my most downloaded resources.
