Sea Floor Spreading I part of Pedagogy in Action:Library:Mathematical and Statistical Models:Examples
In this introductory Excel tutorial (Activity I) students use Excel to explore the geodynamics model equation for ocean depth around a sea-floor spreading center. For students with no prior Excel experience.

Sea Floor Spreading II part of Pedagogy in Action:Library:Mathematical and Statistical Models:Examples
Students import ocean bathymetry data from text files, they then use Excel to graph these observations along with model prediction to assess the model's ability to simulated the observed topographic features of the North Atlantic.

Human Demographics part of Pedagogy in Action:Library:Mathematical and Statistical Models:Examples
In this biology simulation students explore factors that change human population growth including age at which women begin to bear children, fertility rate and death rate.

Genetic Drift part of Pedagogy in Action:Library:Mathematical and Statistical Models:Examples
In this biology simulation, students use a mathematical simulation of genetic drift to answer questions about the factors that influence this evolutionary process. Students run a series of simulations varying allele frequency and population size and then analyze their data and propose a model to explain their results.

Earthquake Demonstration part of Pedagogy in Action:Library: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 during an earthquake.

Crystallization from Melt Demonstration part of Pedagogy in Action:Library:Interactive Lecture Demonstrations: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 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 ...

Fog Chamber part of Pedagogy in Action:Library:Interactive Lecture Demonstrations: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.

Phases of the Moon part of Pedagogy in Action:Library:Interactive Lecture Demonstrations: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 Pedagogy in Action:Library:Interactive Lecture Demonstrations:Examples
Use a Slinky to show:P and S waves, Wave reflection, and Standing waves in interactive lecture demonstration.

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.

Using Mass Balance to Understand Atmospheric CFCs part of Pedagogy in Action:Library:Teaching with Data:Examples
Students use an interactive online mass balance model help understand the observed levels of chlorofluorocarbon CFC-12 over the recent past.

Monohybrid Fruit Fly Crosses: A Simulation part of Pedagogy in Action:Library:Teaching with Data:Examples
This assignment uses a computer simulation of fruit fly genetics to have students design and interpret monohybrid crosses of a trait with simple dominant and recessive alleles. Detailed instructions with animated examples, background material, a sample report and a rubric are included.

Writing a Wikipedia Genetic Disease Article part of Pedagogy in Action:Library:Teaching with Data:Examples
Writing a Wikipedia article about a genetic disease is a good culminating activity for a genetics course or module, as it requires synthesizing and interpreting a wide range of genetic information. This assignment also includes a potential service component, which is normally very difficult in genetics.

Phenylketonuira part of Pedagogy in Action:Library:Teaching with Data:Examples
In this activity, students are assigned different alleles of the gene for phenylalanine hydroxylase to research using OMIM (Online Mendelian Inheritance in Man). They are then asked to both explain and illustrate how this mutation may cause the disease phenylketonuria (PKU).

Problem-Based Learning: UV Menace part of Pedagogy in Action:Library:Cooperative Learning:Examples
Students work as a team to determine the causes, effects, and solutions to ozone depletion. They work out what they need to know, and split the team up to research different parts of the issue.

Describe and Interpret Images: Folded Strata part of Pedagogy in Action:Library:Interactive Lectures:Examples
In class, have students make a simple sketch of an outcrop shown in a slide (or computer projection) then discuss possible interpretations.

Constructing Phylogenetic Trees: The Whippo Story part of Pedagogy in Action:Library:Interactive Lectures:Examples
An interactive lecture in which students use data on feeding habits and habitat, skeletons, and DNA sequences to draw phylogenetic trees.

Climate: Global Warming part of Pedagogy in Action:Library:Socratic Questioning:Examples
Detailed, annotated example of Socratic questioning for topics of climate change, global warming, and greenhouse gases in the atmosphere.

Acid Rain Socratic Questions part of Pedagogy in Action:Library:Socratic Questioning:Examples
Cluster of questions on acid rain deposition.
