A great activity for mole day (10 / 23) or with radioactive decay! In this activity, students will predict when a 'mole of a substance' was presence. Based upon radioactive decay rate of a substance, the initial amount found, and the mole concept students will create a graph and interpolate within the graph. Teachers can customize this activity so each student has a different mole they are seeking.
