Fizzics with Mr Mackenzie is an educational physics resource that supports students studying Scottish qualifications, including National 5, Higher and Advanced Higher. Created by physics teacher Mr Mackenzie, the site organizes learning materials by course and topic, helping students review concepts and practise problem-solving.

Its content covers areas such as forces, electricity and energy, dynamics and space, particles and waves, and the wider universe. Resources include explanatory notes, worked examples, short instructional videos and downloadable or viewable PDF e-books. Topics range from drawing electric and magnetic field lines to calculating the work done on charged particles and their speed in electric fields. The site also explores fundamental particles and the Standard Model, dark matter, dark energy, and cosmology.

Fizzics with Mr Mackenzie is designed to make physics concepts easier to revisit through concise explanations and multimedia learning materials. Students can browse posts by course or subject category, use the materials to recap classroom learning, and access selected videos hosted on Vimeo.
