Determining Dinosaur Speeds
This exercise has students determine how fast a dinosaur was moving based on the tracks it made. It allows students with minimal quantitative background to become motivated and begin to develop an appreciation for dimensional analysis as they see whether or not they could outrun the track-making dinosaurs. Measurements from any dinosaur track site can be used in this activity. Learning goals, context for use, teaching tips, materials, assessment tips and related resources are provided.
Two streams, two stories: How Humans Alter Floods and Streams
In this class activity, students determine the discharge of a 100-year flood for two human-impacted streams. This activity supports the quantitative concepts of recurrence intervals, floods and flooding, and probability. It is appropriate for a class of under 40 students. This assignment uses real data, asks students to graph and interpret data, examines the errors associated with that data and its analysis, and requires the students to look at societal impacts. Learning goals, context for use,
Viscosity of the Mantle: Constraints from Post-glacial Rebound
In this lab, students determine the viscosity of a relatively viscous fluid by measuring the rate of rebound of a partially submerged object following a rapid decrease in its mass. This experiment is carried out in the context of an analysis of post-glacial rebound as a measurement of the viscosity ...
BBC In Depth: Hurricane Katrina
This BBC News clearinghouse website provides a wide variety of information regarding Hurricane Katrina. Information includes news stories, scientific analysis and background, eyewitness accounts, photo galleries, pressing questions, hurricane animations and more. Information has been updated frequently.
Stochastic Evolution Equati
The lectures are at a beginning graduate level and assume only basic familiarity with Functional Analysis and Probability Theory. Topics covered include: Random variables in Banach spaces: Gaussian random variables, contraction principles, Kahane-Khintchine inequality, Anderson’s inequality. Stochastic ...

Mating preference in the commercially imported bumblebee species Bombus terrestris in Britain (Hymen
Commercial trade of bumblebees in Europe results in different subspecies of Bombus terrestris being shipped into regions where they are not native. Although previous studies have shown that these subspecies will interbreed, none have assessed mating preference of the different populations. This study examines the mating preferences between two geographically isolated populations of B. terrestris which have unnaturally been brought together through the commercial trade in bumblebees. Under contr
Star Library: Which Paper Towel is More Absorbent?
This group activity focuses on conducting an experiment to determine which of two brands of paper towels are more absorbent by measuring the amount of water absorbed. A two-sample t-test can be used to analyze the data, or simple graphics and descriptive statistics can be used as an exploratory analysis. ...
Star Library: What is the Shelf Life?
The Food and Drug Administration requires pharmaceutical companies to establish a shelf life for all new drug products through a stability analysis. This is done to ensure the quality of the drug taken by an individual is within established levels. The purpose of this out-of-class project or in-class ...
The applet in this section allows for simple data analysis of univariate data. Users can either generate normal or uniform data for k samples or copy and paste data from another source to a text box. A univariate analysis is performed for all k samples.
This applet from Statistical Java allows the user to generate bivariate data for analysis with simple linear regression. The page describes the equations used to generate the data and estimate the regression lines.
Science as Investigation: A First Majors Course Teaching the Process
The first laboratory course biology majors take should challenge their expectation that biology is the mere memorization of knowledge. Rather, it should introduce them through experience to the scope and limitations of scientific investigation. Following a brief introduction to epistemology and the nature and goals of science, this course provides students with a developing understanding of scientific thinking, methodology, and experimental design. During the final unit of the course students de
Seafood Forensics: Crabby Proteins
A laboratory exercise to perform protein analysis of crab tissue using horizontal agarose gel electrophoresis to determine if species substitution has occurred.
Spot-Overlay Ames Test of Potential Mutagens
This protocol represents a cost-effective modification of the Ames Test that allows students to investigate the mutagenic potential of various common substances. Potential mutagens are tested using well-characterized auxotrophic strains of Salmonella typhimurium. By analyzing the results, students determine if any of their compounds may be mutagenic. Follow-up experiments are designed to determine the dose response of these potential mutagens. Using this protocol, we have achieved reproducible r
The Cypress Swamp
A laboratory exercise involving observing various plants and animals encountered and measuring physical factors that affect them as an approach to ecosystem analysis.
What I Could Teach Darwin Using "Darwin 2000"
A laboratory to demonstrate the use of the "Darwin 2000" website to train undergraduates to use online molecular databases and analysis tools, fostering their understanding of how genes and proteins evolve.
