Geologic Puzzles: Morrison Formation part of Examples
Images of faulted strata, tilted turbidites, and beach rocks bring the field into the classroom, giving students practice in doing what geoscientists do. These images are examples of geologic puzzles.

Magma Viscosity Demos part of 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.

How Fast Do Materials Weather? part of Examples
A think-pair-share activity in which students calculate weathering rates from tombstone weathering data.

Carbon Dioxide Exercise part of Examples
Students work in groups, plotting carbon dioxide concentrations over time on overheads and estimating the rate of change over five years.

Externalities in the cashmere market: Colbert Report interview part of Examples
In this interactive lecture, students watch a video clip from The Colbert Report that addresses pollution externalities. Students graph the market and use the write-pair-share technique, then brainstorm ways to move the market to the socially efficient equilibrium.

Pro-Con-Caveat Grid part of Examples
The pro-con-caveat activity is a quick and easy way to engage students through a more interactive lecture experience.

Interactive lecture on diminishing marginal product: tennis ball production part of Examples
In this interactive lecture, students "produce" tennis balls with fixed capital and increasing labor, generating a production function. Students calculate the marginal product of each work and discover that marginal product falls as the number of workers rises.

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

Simple Mendelian Genetics: An interactive lecture using "DNA from the Beginning" part of Examples
An interactive lecture that uses flash animations showing the researcher and their experiments that were used to develop the basic concepts in Mendelian genetics. Includes multiple choice questions students can answer in class.

Social Class Symbols: In-class Activity Game part of Examples
This sites provides three interactive games related to social class and personal possessions indicative of class.
