In Activity A, you can just press play and wait. In Activity B, you often have to work backward. The simulation might ask you to find the age of an object that already has decayed. You cannot "un-decay" the atoms. You must use the mathematical relationship described above. If the simulation allows you to manipulate time sliders, use them to match the percentage shown on the probe.
In Activity B of the Half-Life Gizmo, users determine half-lives by using the half-life probe on the graph tab to identify when radioactive atoms reach 50% capacity, with Isotope A measuring at 31 seconds. The activity also involves measuring Isotope B, typically 17 seconds, and applying these decay principles to estimate the age of carbon-14 samples like papyrus and charcoal.

The half-life of Nexarium is 1 minute.
That's when she remembered a useful tool she had used in the past - the Half Life Gizmo. The Gizmo was a virtual laboratory simulation that allowed her to experiment with different radioactive substances and measure their half-lives. In Activity A, you can just press play and wait
