• Constructing Phylogenetic Trees: The Whippo Story An interactive lecture in which students are presented with three sets of data from which they draw phylogenetic trees.
• Simple Mendelian Genetics: An interactive lecture using DNA from the Beginning This active uses a flash based animation, "DNA from the Beginning," to introduce students to the researchers and their experiments that led to the current model for inheritance of genes.
• What Determines Gender in Humans? In this activity students examine karyotypes from five individuals to try to identify which chromosomes determine gender in humans.

• The Crusty Loaf of Bread: An Exploration of Area of a Surface of Revolution This write-pair-share activity for Calculus II students involves a hypothetical hemispherical loaf of bread with a 12-inch diameter that has been sliced into twelve one-inch-thick slices.
• How Much Work is Required: Intuition vs. Mathematical CalculationThis classroom activity presents Calculus II students with some Flash tutorials involving work and pumping liquids along with a simple question concerning the amount of work involved in pumping water out of two full containers.
• Mathematical Curve Conjectures In this write-pair-share activity, a six-foot length of nylon rope is suspended at both ends to model a mathematical curve known as the hyperbolic cosine.
• Partial Derivatives: Geometric Visualization This write-pair-share activity presents Calculus III students with a worksheet containing several exercises that require them to find partial derivatives of functions of two variables.
• Volumes of Solids of Revolution This write-pair-share activity presents Calculus II students with a worksheet containing several exercises that require them to find the volumes of solids of revolution using disk, washer and shell methods and to sketch three-dimensional representations of the resulting solids.
