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:Geology:Historical Geology, Geochemistry:Radioisotopes

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: Mathematics, Geoscience:Geology:Geochemistry:Radioisotopes

Sonar Demonstration -- Human Sound Wave part of Cutting Edge:Courses:Oceanography:Activities
Sonar technology allowed scientists to produce high-resolution maps of the sea floor for the first time. This sonar demonstration uses a Human Sound Wave to image the "sea floor" in a lecture hall. In ...

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.

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

Subduction Zone Earthquakes part of Pedagogy in Action:Library:Interactive Lecture Demonstrations:Examples
While working in groups to facilitate peer tutoring, students manipulate a hands-on, physical model to better comprehend several characteristics of subduction zone earthquakes.

Subject: Environmental Science:Natural Hazards:Earthquakes, Geoscience:Geology:Tectonics, Geophysics:Seismology

Igneous Rocks Model part of Pedagogy in Action:Library:Interactive Lecture Demonstrations:Examples
While working in groups to facilitate peer tutoring, students use samples of four igneous rocks (gabbro, basalt, granite, and rhyolite) to observe differences in texture, color and grain size and make inferences ...

Subject: Geoscience:Geology:Igneous and Metamorphic Petrology:Igneous Rocks

Copper Extraction Demonstration Tutorial part of Pedagogy in Action:Library: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 ...
