Phases of the Moon part of Examples
This exercise has students use a simple physical model of the Earth, sun, and moon to understand why the moon changes phases from the perspective of Earthly observers. -

Topics: Solar system

Using Melting Ice to Teach Radiometric Decay part of Quantitative Skills:Activities: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. -

Topics: Time/Earth History

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

Topics: Time/Earth History

Earthquake Demonstration part of 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 ...

Topics: Structural Geology:Joints/Fractures

Crystallization Demonstration part of Examples
This demonstration uses melted phenyl salicylate to show how crystals nucleate and grow as the temperature of the liquid melt decreases. -

Topics: Chemistry/Physics/Mathematics

Water Contamination Demonstration part of Examples
Dorothy Merritts, Franklin and Marshall College (dorothy.merritts@fandm.edu) Summary: Misplaced Matter and Water Pollution The drinking water pollution demonstration provides a very simple but ...
