The Crazy Scientist® gives Australian parents, teachers, and schools free, curriculum-aligned science experiments for kids from Preschool to Secondary. Every experiment is created by a science teacher with 30+ years in the classroom, built on real inquiry-based learning — not just a video to watch. With 79+ free experiments across Explosions & Fizz, Slime & Weird Materials, Space & Rockets, and 20+ more categories, it's fast becoming Australia's go-to home for hands-on STEM.
Trusted by parents, teachers and schools
100+ FREE investigations built for the way science is meant to be taught.
Aligned with the NSW Science and Technology K–6 Syllabus (2024)
