In this activity students explore the evolution of proteins by comparing 2D and 3D alignments of orthologs and paralogs.
Evolution, Natural Selection and Speciation
scott cooper, UW-La Crosse
In this out of class tutorial, students explore several examples of natural selection and speciation.
Evolution of Whales
Mitchell Colgan, College of Charleston
The students read two articles on the evolution of whales and search the web. The students' writing assignment requires them to outline the evolution of whales using major fossil finds. Students start with ...
Evolution in Your "Pet" Group
Peg Yacobucci, Bowling Green State University-Main Campus
This writing exercise asks students to use library resources to locate a peer-reviewed journal article that describes research on the evolution of their individual "pet" taxonomic group. After reading the ...
Evolution of antibiotic resistance in bacteria
Elena Bray Speth, Saint Louis University-Main Campus
This activity is intended to guide students to apply principles of evolution by natural selection to explain a real world biological phenomenon (the evolution of bacteria populations resistant to common ...
Evolution vs. Creationism Term Paper Assignment
Katherine Bulinski, Bellarmine University
A term paper assigned for a Evolution vs. Creationism freshman seminar class. The purpose of this assignment is to allow students to critically evaluate one aspect of the Evolution vs. Creationism debate.
Evolution of Normal Fault Systems During Progressive Deformation
Bob Burger, Smith College
This activity is based on QuickTime movies and color digital photographs derived from sandbox experiments that produce normal faults in a variety of boundary conditions following experiments developed by Ken ...

This laboratory exercise focuses on the connections between plant genetics and morphology.
Teaching geologic time and rates of landscape evolution with dice
Kate Ruhl, Massachusetts Institute of Technology
Landscape evolution provides a convenient framework for understanding geologic time and rates because students can observe how processes like erosion and deposition shape their surroundings. In this example, students build 3-D sandbox models based on topographic maps and design and stage a "virtual adventure race." Sandbox landscapes are used to illustrate erosional processes,while local examples are used to discuss landscapes as transient or steady over different time- and length scales. Dice experiments illustrate radioactive decay and the shape of the age equation curve, and 14C dating, geochronology and thermochronology are introduced as "stopwatches" that start when a plant dies, a crystal forms, or a rock nears the surface and cools to a certain temperature. The sandbox model and thermochronometer "stopwatches" are combined to measure erosion rates and rates of landscape change. Ultimately, model rates (cm/hour) calculated from stopwatch times on the order of seconds can be related to geologic rates (km/My) calculated from real million-year-old samples.
