Let pupils try it in the lab, then test themselves. TRY BEFORE YOU BUY: download the free sample (the complete Light topic: 4 labs and 36 questions) from my shop. This is a single web page that opens in any up-to-date browser (Chrome, Edge, Firefox, Safari, Chromebooks). No installs, no accounts, no internet needed, and no pupil data collected. It works brilliantly on a classroom board or on pupils’ own devices. WHAT’S INSIDE • 12 topics (this is not a full KS3 course): How to be a Scientist, Separating Mixtures, Solubility, Changes of State, Controlling Reactions, Light, Invisible Radiation, Forces, Gravity, Cells, Microbes and Body Defence • 41 interactive labs, including a Bunsen burner licence, distillation, chromatography “who wrote the note?”, rates of reaction with a gas syringe, a thermal camera, X-rays, refraction through a prism, a working microscope, phagocytes engulfing bacteria and vaccine tag • Zoom lenses show what the particles and cells are doing next to the apparatus • Live tables and graphs that fill in as pupils investigate, with repeats and averages • 450 self-marking questions across 78 short lessons: multiple choice, true/false and type-the-word • Every wrong answer explains why it is wrong, not just what the right answer is • Results screen with a lesson-by-lesson breakdown, key facts to revisit and “retry the ones I got wrong” • 10-question topic quizzes and a 15-question mixed review across all topics • Teacher guide (PDF) with contents, lesson ideas and set-up help GREAT FOR Starters and plenaries · Rehearsing a practical before you do it · Covering practicals you can’t run (X-rays, UV, distillation) · Homework and revision · Cover lessons ACCESSIBILITY High-readability font (Atkinson Hyperlegible), large text that scales on boards, light and dark mode, keyboard controls and reduced motion support. HOW TO USE Download, unzip and double-click “Science Labs and Review.html”. Works best on laptops, Chromebooks and classroom boards. To share with pupils, put the file in your class area for them to download and open. It is a file, not a web link, so Google Drive and Teams will not run it as a preview. Scores are saved on each device; there is no teacher dashboard.

This resource package for Scottish National 5 and Higher Chemistry includes a standalone, offline-capable HTML electrolysis simulator that lets students toggle between course levels to visually trace ion migration and product formation across five different electrolytes. Alongside the digital simulator, the pack contains a structured pupil worksheet for recording predictions and writing equations, a comprehensive teacher mark scheme for quick grading, and a clean, professional cover image,

This interactive educational resource package is designed for the Scottish National 3 Science and National 4 Chemistry curriculums, directly supporting the Atomic Structure & Chemical Changes units. The core component is an offline-capable, standalone digital app (atomic-structure-builder.html) that allows pupils to tap any of the first 20 elements to dynamically view its Bohr model, particle counts, and electron configuration, or test themselves using a built-in multiple-choice quiz mode. Alongside the digital builder, the package includes a 20-mark pupil recording sheet (atomic-structure-recording-sheet.pdf) to guide students through data collection, core conceptual questions, and self-assessment, a matching teacher mark scheme (atomic-structure-mark-scheme.pdf) with complete grading guidance and suggested grade boundaries, and a clean, modern cover image (atomic-structure-cover.png) to complete the resource pack.

An interactive browser-based pulse rate simulator plus printable pupil worksheet and full teacher mark scheme. No software required opens in any browser. Includes: animated heartbeat simulator (4 activities: resting, walking, running, sprinting), Compare Activities bar chart, Count the Beats 30-second timed mode with accuracy feedback, collapsible learning intentions and success criteria, pupil recording sheet (10 marks, A4 PDF), and full teacher mark scheme with grade guidance.
