Elements and Compounds

KS3 - Elements, Compounds and Mixtures Bundle

A comprehensive, complete, engaging and challenging set of lessons and activities to teach students the basics of elements, compounds, mixtures and chemical formulas. This scheme/package is designed with non-science/non-chemistry specialist teachers in mind! **Lessons included in this bundle:** 1. Elements and Compounds 2. Chemical Formulas 3. Counting atoms in a Formula 4. Pure Substances 5. Mixtures **Included in each lesson:** 1. Lesson powerpoint - including teacher notes and answers in "notes" section 2. Student-led lesson worksheet 3. Teacher answer sheet **Lesson resources contain:** 1. In-built stretch and challenge tasks throughout 2. In-built scaffolded learning for lower abilities 3. Various AFL activities to assess progress and understanding that you can tailor to fit any class or available resources (these include “think, pair, share”, molymod activities, mini-whiteboard quizzes) 4. Relevant risk assessments for any practical work (updated as of March 2023) **By the end of the topic, students will:** * Know what an “element” and a “compound” is * Describe the difference between an element and a compound * Know what an “atom” and a “molecule” are * Describe the difference between an atom and a molecule * Draw/make particle diagrams and models to represent elements, compounds, single atoms and molecules * Understand why scientists use chemical symbols to represent elements * Identify simple elements from their chemical symbols * Identify elements in a chemical formula * Classify chemical formulas as elements or compounds * Count the number of atoms in a basic formula * Identify elements in a chemical formula * Count the number of atoms in formulas containing subscripts * Count the number of atoms in formulas containing multipliers * Describe what a pure substance is * Identify examples of pure substances in everyday life * Identify pure substances from particle diagrams and examples * Carry out a practical investigation to identify pure substances * Describe what a mixture is * Give examples of mixtures in everyday life * Identify mixtures from particle diagrams and examples * Draw/make models representing mixtures
