Development of the Atomic Model
<p><strong>Complete No-Prep lesson</strong> with <strong>exam questions, tasks and answers</strong> 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.</p>
<p>As a Secondary Science teacher and Deputy Headteacher for many years I make high quality <strong>no-prep</strong> lessons so busy teachers can teach <strong>outstanding lessons without spending hours planning.</strong> This high quality lesson includes explanations, different types of in-lesson assessment (all <strong>with answers</strong>) and <strong>unique exam questions</strong>.</p>
<p>My lessons are <strong>ideal for non-Physicists</strong> - 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 <strong>preview video</strong> shows a representative sample of slides from the resource so that you get a good idea of what it includes before you buy.</p>
<p><strong>What’s Included:</strong><br />
• Starter / Do Now Activity<br />
• Explanation slides in “chunked” sections with <strong>animated diagrams</strong>.<br />
• Multiple questions in different question styles and difficulties - no need for worksheets. Each “chunked” explanation section typically includes a set of “<strong>learning check / quick questions</strong>” followed by a set of <strong>in-depth questions</strong> on the learning from that “chunk” of the lesson. All questions have <strong>answers</strong>.<br />
• <strong>Exam-style questions</strong> 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.<br />
• <strong>Answers</strong> for all questions<br />
• All easily editable to adapt to your teaching or to use in existing lessons.<br />
• Slightly humorous, at points, if you like that sort of thing (or just delete those bits if you don’t).</p>
<p><strong>Learning objectives:</strong></p>
<ul>
<li>Describe how new experimental evidence may lead to a scientific model being changed or completely replaced.</li>
<li>Describe how our model of the atom has changed over time because of:</li>
<li>The discovery of the electron.</li>
<li>The alpha scattering experiment.</li>
<li>The discoveries of energy levels, protons and neutrons.</li>
<li>Describe the alpha scattering experiment, and the new evidence it produced.</li>
<li>Explain why the evidence from the alpha scattering experiment changed the model of the atom.</li>
<li>Describe the plum pudding model of the atom and why it changed.</li>
<li>Describe the differences between the plum pudding model and the nuclear model of the atom.</li>
</ul>
<p>The lesson was written for AQA GCSE Science / Physics but is very likely to be applicable to other exam specifications.<br />
