Drawing SuperHero Task – Elements, Compounds & Alloys Subject: Grade 8 Science (Chemistry / Materials Science) Core Objective: Students apply their knowledge of chemical substances by designing an original superhero whose powers, weapons, and defenses are based on the real properties of 2 elements, 2 compounds, and 2 alloys

The Chemist’s Dozen: How to Count What You Can’t See A Concrete-to-Abstract Lesson for IGCSE Chemistry (Grades 9–10) I created this worksheet to help students bridge the gap between the tangible and the abstract when introducing the mole concept and Avogadro’s number. The activity uses simple packs of beans—each containing exactly 12 seeds—to represent the idea of a fixed counting unit (like a dozen). Students physically count, weigh, and compare different bean packs before I ever introduce the term “mole.” This hands-on foundation allows them to discover key ideas on their own: • Number is independent of mass and size — a dozen mung beans looks and weighs differently from a dozen soybeans, but the count is the same. • Counting by weighing — if you know the mass of one pack, you can determine the mass of a single bean without counting it individually. • The “pack” as a unit — just as a dozen is a fixed number, a mole is a fixed number (6.022 × 10²³), and the mass of one pack becomes the molar mass. The worksheet includes structured observation prompts, a step-by-step lesson flow, and Higher Order Thinking Skills (HOTS) questions that push students to analyze, evaluate, and extend the analogy—from comparing packs to tackling reverse problems like determining the mass of a single lentil without opening its pack. This approach has worked well in my classroom to make the mole concept feel intuitive before introducing the formal definition. Thought I’d share in case it’s useful for other chemistry educators teaching this tricky but foundational topic. #ChemistryTeaching #IGCSE #MoleConcept #ActiveLearning #STEMEducation

Title: People, Places, and Particles: An Analogy for States of Matter Core Idea: You use a familiar school environment (classroom, canteen) and student behavior to model the three states of matter – solid, liquid, gas. The analogy links: Fixed classroom → Solid (fixed pattern, little movement) Can move in the canteen → Liquid (more freedom, movement around others) “Freedom” (implied gas) → Gas (fast, independent movement) Your table captures four key scientific ideas through analogy: State/Conditions → Pattern/Arrangement → Space to move → Type of movement → Excitement

Help your students visualize the invisible! This worksheet uses a simple but powerful school-based analogy (students in a classroom vs. the canteen vs. outside) to help them understand the behavior of particles in solids, liquids, and gases. Students analyze images and environments to deduce arrangement, movement, and energy. A great hook for MYP Science or any middle school chemistry unit.
