Exploring Radiometric Dating with Dice part of Quantitative Skills:Activity Collection
An activity in which students use dice to explore radioactive decay and dating and make simple calculations.

Subject: Geoscience:Geology:Geochemistry:Radioisotopes, Mathematics

Demonstration of radioactive decay using pennies part of Quantitative Skills:Activity Collection
A demonstration (with full class participation) to illustrate radioactive decay by flipping coins. Shows students visually the concepts of exponential decay, half-life and randomness. Works best in large classes – the more people, the better.

Thermohaline Circulation Demonstration part of Cutting Edge:Courses:Oceanography:Activities
This activity helps the students to visualize the effects of temperature and salinity on water density, and the resulting thermohaline circulation. Important processes visualized in this demonstration are ...

Magma Viscosity Demos part of Pedagogy in Action:Library:Interactive Lectures:Examples
This is an interactive lecture where students answer questions about demonstrations shown in several movie files. They learn to connect what they have learned about molecules, phases of matter, silicate crystal structures, and igneous rock classification with magma viscosity, and to connect magma viscosity with volcano explosiveness and morphology.
