Protein Evolution part of Examples

In this activity students explore the evolution of proteins by comparing 2D and 3D alignments of orthologs and paralogs.

Long Term Ecological Resources part of Examples

Students analyze data on temperature and precipitation collected from 26 different Long Term Ecological Research sites and compare them with annual net primary productivity. The students then form an ecological rule to explain their results.

Phenylketonuira part of 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).

Searching Genbank part of Examples

An active problem-based assignment that uses the Genbank database to teach the basics of molecular biology and molecular evolution

Plant Pest Control part of Examples

This learning experience introduces participants to scientific inquiry, hypothesis formation, experimental design, data analysis, and interpretation.

Stratospheric Ozone part of Examples

Students explore observational data from ozone-sondes, TOMS, and UARS measurements to learn about changes in stratospheric ozone over the past several decades.

Water Quality-Total Dissolved Solids part of Examples

Students use a microcomputer connected to a conductivity probe to measure the total dissolved solids in local area water samples.

Stream Characteristics Lab part of Quantitative Skills:Activity Collection

Students determine the relationship between the sinuosity of a river and its gradient by calculating gradients and sinuosity, and generating a graph on Excel. They then test the relationship by making measurements on a picture generated on Google Earth.

Virtual Photoelectric Lab part of Simulations:Examples

This is a virtual lab activity on the photoelectric effect based on a Java applet simulation of the experiment.

Using an Applet to Demonstrate Confidence Intervals part of Simulations:Examples

Students will utilize an applet to further expand their knowledge of confidence intervals.

Simulating Size and Power Using a 10-Sided Die part of Simulations:Examples

This group activity illustrates the concepts of size and power of a test through simulation. Students simulate binomial data by repeatedly rolling a ten-sided die, and they use their simulated data to estimate the size of a binomial test.

Simulating the Effect of Sample Size on the Sampling Distribution of the Mean part of Simulations:Examples

A java applet that simulates the sampling distribution of the mean. It allows students to explore the effect of sample size.

Coke vs. Pepsi Taste Test: Experiments and Inference about Cause part of Simulations:Examples

The Coke vs. Pepsi Taste Test Challenge has students design and carry out an experiment to determine whether or not students are able to correctly identify two brands of cola in a blind taste test. In the first ...

Reese's Pieces Activity: Sampling from a Population part of Simulations:Examples

This activity uses simulation to help students understand sampling variability and reason about whether a particular samples result is unusual, given a particular hypothesis. By using first candies, then a web applet, and varying sample size, students learn that larger samples give more stable and better estimates of a population parameter and develop an appreciation for factors affecting sampling variability.

Simulating a P-value for Testing a Correlation with Fathom part of Simulations:Examples

This activity has students use Fathom to test the correlation between attendance and ballpark capacity of major league baseball teams by taking a sample of actual data and scrambling one of the variables to see how the correlation behaves when the variables are not related. After displaying the distribution of correlations for many simulated samples, students find an approximate p-value based on the number of simulations that exceed the actual correlation.

Influence of Outliers on Correlation part of Simulations:Examples

In this visualization activity, students will observe their instructor create a scatterplot and observe how the correlation coefficient changes when outlier points are added. Students are then given a follow up assignment which guides them through the applet. In addition, the assignment provides insight about outliers and their effect on correlation.

Tropical Cyclones and Global Change part of Cutting Edge:Hurricanes-Climate Change Connection:Activities

This is a full semester project focusing on tropical cyclones and climate change for my undergraduate tropical meteorology class. It consists of five parts, outlined below.

Analyzing Hurricanes part of Cutting Edge:Hurricanes-Climate Change Connection:Activities

The exercise uses GIS to explore historical data on hurricanes (path, strength, name). Students identify trends in hurricane records, the impact of hurricanes on major U.S. cities, and how hurricanes change through ...

Tax Game part of Pedagogy in Action:Library:Teaching with Simulations:Examples

The link between a set of taxes and income distribution is an important, but difficult, concept taught in economics principles courses. The Tax Game simulation requires a student to set tax rates for an income tax, a property tax, a wealth tax, a payroll tax, a corporate income tax, a sales tax,and an excise tax. The student can choose any rates he or she wishes, but must achieve a given revenue target.

Economics and the Tragedy of the Commons part of Pedagogy in Action:Library:Teaching with Simulations:Examples

In both macroeconomics and microeconomics principles courses, economists teach the virtue of markets as an allocative mechanism. But markets sometimes fail. This example allows students to simulate the market ...
