Charles Carrigan over at Earth-Like planet has posted a lab activity using M&Ms to teach students about geochronology. I love the method of using the M&Ms as a random number generator (m-up or m-down). The data collection methods could easily be used in a different class to talk about exponential decay and the physics/math behind the phenomenon.
I use an M&M lab to teach Bowen's reaction sequence. Students remove minerals (colors) as the magma cools. One of their favorite labs
