Bring radioactive decay to life with this interactive Half-Life Simulation Lab Bundle! Perfect for General Physics, NGSS, and IB DP Physics classes, this resource helps students visualize and understand how half-life, decay constant (λ), and exponential decay work — not just in theory, but through real-time simulation and data analysis.

Students explore radioactive decay using a click-activated HTML simulation (no installation required), collect decay data, analyze the differences between theoretical and random decay curves, and test their understanding with a self-marked quiz built right into the app. The included worksheet guides them step-by-step, while the answer key ensures quick marking and efficient assessment.
