Complete No-Prep lesson with exam questions, tasks and answers on Development of the Model of the Atom for AQA GCSE (9-1) Science / Physics / Chemistry. Exam Spec: This lesson covers all of AQA GCSE Combined Science 6.4.1.3, Physics 4.4.1.3, and Chemistry: 4.1.1.3. As a Secondary Science teacher and Deputy Headteacher for many years I make high quality no-prep lessons so busy teachers can teach outstanding lessons without spending hours planning. This high quality lesson includes explanations, different types of in-lesson assessment (all with answers) and unique exam questions. My lessons are ideal for non-Physicists - as a Biologist who retrained as a Physics teacher I know how to take learners on a journey that builds up their understanding step by step, while still going into a lot of depth. The preview video shows a representative sample of slides from the resource so that you get a good idea of what it includes before you buy. What’s Included: • Starter / Do Now Activity • Explanation slides in “chunked” sections with animated diagrams. • Multiple questions in different question styles and difficulties - no need for worksheets. Each “chunked” explanation section typically includes a set of “learning check / quick questions” followed by a set of in-depth questions on the learning from that “chunk” of the lesson. All questions have answers. • Exam-style questions on the whole lesson at the end of the lesson- these are unique, based on real exam questions but not just copied from exam boards. • Answers for all questions • All easily editable to adapt to your teaching or to use in existing lessons. • Slightly humorous, at points, if you like that sort of thing (or just delete those bits if you don’t). Learning objectives: Describe how new experimental evidence may lead to a scientific model being changed or completely replaced. Describe how our model of the atom has changed over time because of: The discovery of the electron. The alpha scattering experiment. The discoveries of energy levels, protons and neutrons. Describe the alpha scattering experiment, and the new evidence it produced. Explain why the evidence from the alpha scattering experiment changed the model of the atom. Describe the plum pudding model of the atom and why it changed. Describe the differences between the plum pudding model and the nuclear model of the atom. The lesson was written for AQA GCSE Science / Physics but is very likely to be applicable to other exam specifications. Please leave a rating / review and all other feedback gratefully received!

This ready-to-use cover lesson, based on my atoms, elements, and compounds lesson, allows GCSE students to work independently and develop their understanding of the link between atoms, elements, and compounds through clear explanations and engaging activities. Ideal for unexpected staff absences. This lesson is the 1st in a series of lessons and covers the content from the AQA GCSE 4.1.1(.1) A simple model of the atom, symbols, relative atomic mass, electronic charge and isotopes topic and OUP Kerboodle GCSE Chemistry Scheme C1.1 Atoms lesson. Resource includes: ● Teacher guide (Page 1): Clear instructions on what to print (answer sheet & student worksheet) and any additional resources needed (e.g., graph paper, coloured pencils). ● Answer sheet (Page 2): Provides answers to all student worksheet questions, allowing cover teachers to assist students. ● Student worksheet (Pages 3 & 4 - back-to-back): ○ Clear instructions and explanations guide students through the learning objectives independently. ○ Engaging activities and thought-provoking questions promote active learning and understanding. ○ Fully editable - easily adapt the resource to fit the specific needs of your students and the time available. Benefits: ● Minimal prep: Saves valuable time by providing a complete and ready-to-use lesson resource. ● Independent learning: Allows students to work independently, minimising disruption. ● Fully editable: Easily modify the resource to fit the specific needs of your students. ● Answers: Detailed answer sheets provide guidance for the cover teacher.

This Power Point presentation explain * The concept of atom and the failure of Aristotle Theory * Alchemy and Modern chemistry * Elements * Name and facts about elements

Get as many samples of elements as possible and use to introduce the idea that there are different elements and how they differ. A presentation and accompanying worksheets are included. Test tubes of air can be labelled as gases etc. If needed

Included in the resource: ‘Label the periodic table’ worksheet ‘Key features of the periodic table’ worksheet Answer sheets for both worksheets These are useful introductory worksheets for teaching the periodic table. Worksheet 1: Students label the periodic table based on the words listed. They must also identify what a ‘group’ is and what a ‘period’ is. Students can also identify which regions of the periodic table are metals, non-metals and metalloids. Worksheet 2: Students answer questions on four key regions of the periodic table (alkali metals, halogens, noble gases and transition metals). The questions are based around properties, reactivity and uses. Please see the preview included. Please note that some of my resources may include American spellings.

This PowerPoint provides a creative and easy to use resource for introducing atoms, elements, and the differences between them. It includes a few shorter activities that engage students as well as a longer writing task.

Learning outcomes: Define the key words atom and element Identify elements from their symbols Describe the basic structure of the periodic table

This is the first of 5 lessons aimed at giving students from year 7 a good grounding in atoms and elements. The lesson covers the origin of the word atoms, the definition of atoms, the original ideas about the indivisibility of atoms. It introduces students to the 3 subatomic particles and the importance of each to the atom. The lesson introduces elements and the purity of elements. It explains why elements are different from each other. The early idea that there were just 4 elements that combined to make up everything that exist. The lesson introduces students to the occurrence of elements, a video link to when individual elements were discovered so that they can appreciate that elements were not all discovered at the same time. Students are also introduced to how elements are extracted.Students learn that elements can be classified in many ways; metals, non-metals, solid, liquid or gas. It provides students an interesting understanding of how elements obtained their names. There is an ICT activity that students can complete as homework to research examples of elements named by different categories. The link between the symbol of an element and its names, highlighting why the symbol of an element like potassium is K , meanwhile there no K in the English name for the element. Each slide has an audio to help students who would like to listen and read at the same time. The lesson finishes with a summary fill in the gap worksheet that students complete. Answers provided.

AQA (9-1): Combined Science Trilogy Chapter 9: Atomic Structure and the Periodic Table This presentation includes: Structure of the atom Elements: Identifying chemical symbols of the first 20 elements Isotopes Relative atomic mass calculations

Please provide feedback or comment on the resource. Lesson Includes: PowerPoint and Worksheet Activity Lesson Objective: To be familiar with the subatomic particles within atoms. Success Criteria: I can recall the properties of protons, neutrons and electrons. I can calculate the maximum number of electrons in each shell.
