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...

New Review Engineering the Half Pipe—Science of the Winter Olympic Games
There are no tricks here! Young scholars learn about the concept of centripetal acceleration by studying the design of the snowboarding half pipe. A video lesson describes how the half pipe design affects the motion of the boarders.

Teaching Radioactive Decay: Radioactive Half-life And Dating Techniques
Students generate a radioactive decay table for an imaginary element using a box filled with pinto beans and M&M's. They use their data to plot a decay graph, develop the concept of half-life, and use the graph to "age" several samples.
