Interactive simulation covering investigating the refraction of light (AQA P14.2 / Edexcel GCSE 14.9 / IGCSE 3.2.3) Students choose a material and alter the angle of incidence, recording the angle of refraction. They can view it as a ray model or wave model. Worksheet for lesson included and a quiz integrated into the interactive. Designed to reduce cognitive load - no distractions, one concept, focused on exam-relevant outcomes. https://simpliphys.com/gcse/simulations/waves/refraction

Interactive circuit builder covering simple circuits in series and parallel (AQA 4.2.2 / Edexcel IGCSE 2.15/GCSE 10.17) Students add components and wire them up. Readings of current and voltage can be taken. Accompanying worksheet guides students to build series and parallel circuits and look for patterns in current and voltage. Quiz included in the interactive to check for understanding.

Interactive simulation covering the Force of Friction (AQA 4.5.1.2 / Edexcel GCSE 9.1 / IGCSE 1.16). Students pull a newtonmeter attached to a block. Static and kinetic friction are recorded. 4 different surfaces can be investigated. As an extension, they can add masses to the block to increase the normal reaction force.
