Using Melting Ice to Teach Radiometric Dating part of Quantitative Skills:Activity Collection
Students are challenged to a Sherlock Holmes-style mystery in which they construct their own decay curves of melting ice to determine time-zero.

Subject: Geoscience: Geoscience:Geology:Historical Geology, Geochemistry:Radioisotopes

Earthquake Demonstration part of Starting Point-Teaching Entry Level Geoscience:Interactive Lecture Demonstrations:Examples
This demonstration uses an "earthquake machine" constructed from bricks, sand paper, and a winch, to simulate the buildup of elastic strain energy prior to a seismic event and the release of that energy ...

Subject: Geoscience: Environmental Science:Natural Hazards:Earthquakes, Geoscience:Geology:Structural Geology:Microstructures, Deformation Mechanisms, Fabrics

Copper Extraction Demonstration Tutorial part of Starting Point-Teaching Entry Level Geoscience:Interactive Lecture Demonstrations:Examples
Summary This demonstration uses sulfuric acid and crushed copper ore (malachite) to produce a solution of copper sulfate and carbonic acid in a beaker. When a freshly sanded nail is dropped into the copper sulfate ...

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.
