Demonstrating the Half-Life of a Radioactive Isotope
In this half-life worksheet, students use 100 pennies to simulate radioactive isotopes and half-life. They place the pennies in a box and shake the box. All pennies that turn up tails are removed from the box. They represent the isotopes...

Exponential Decay Formula (can skip, involves Calculus)
Sal continues his discussion of decay by showing students the math involved in determining how much a substance is left after one half-life, two half-lives, and even three half-lives have gone by. He sets up a general function of time...

Is Our Climate Headed for a Mathematical Tipping Point?
Raising the global temperature by two degrees may not seem like much, but the impact this would have on the planet is amazing. Follow along with this short video as it examines how even a small change to a system can turn its regular,...
