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.
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.
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.
Slinky and Waves part of Examples
Use a Slinky to show:P and S waves, Wave reflection, and Standing waves in interactive lecture demonstration.
Fog Chamber part of Examples
Show how clouds and fog are created with a very simple physical model. Materials needed are: A large 1 gallon jar, latex glove, a little water, and matches.
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 of that energy during an earthquake.
Crystallization from Melt 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.
Copper Extraction Demonstration Tutorial part of 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 ...
Igneous Rocks Model part of 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 ...
Subduction Zone Earthquakes part of 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.
