“5 Second Rule” Science Kit – Test the Myth! 🦠 Does time on the floor really matter? Let’s find out. We’ve all heard it — “It’s fine, it was only on the floor for five seconds!” But is it really? This hands-on science kit lets students investigate the famous “5 Second Rule” in a way that feels real, exciting, and totally doable at home. In our experience, this experiment sparks some of the best family science conversations. Watching bacteria grow on agar plates makes the invisible world suddenly very visible — and students quickly realize that science is about testing ideas, not just repeating them. This is a flexible 2–3 day experiment that can easily expand into a multi-week science fair project using the included journal prompts, data tables, and digital curriculum guide. What Students Will Do • Swab floors after different time intervals • Grow bacteria using ready-to-use agar plates • Count bacterial co
