Building Trees to Understand Evolutionary Relationships

by Ben Higgins and Satina Ciandro

How do students begin to make sense of the vast diversity of life? Even when exposed to just a sliver of such diversity, it is commonplace for students to become disengaged. This module is a first step in understanding why and how animals are classified and to become excited about the process.

The purpose of this module is to use the traits that each species possess to develop an understanding of species relatedness. Upon completion of this module, students should have a better understanding of why assemblages of animals are classified together. This module is an opportunity for students to learn: 1) How organisms are grouped together and 2) How to interpret relationships among groups of organisms.

Assessing Biodiversity Using a School Garden

by Jenn Yost, Carla Fresquez and Bill Callahan

One way that we can protect biodiversity is by restoring degraded habitats to more natural conditions. This process can be simulated at a school through the restoration of a degraded plot of land into local native plant communities. Planting a native garden is a way to expose students to local biodiversity, teach them the importance of biodiversity, and mimic what can be done on a large scale to restore ecosystems once they are degraded.

Students 1) develop their own methods to quantify biodiversity, 2) measure biodiversity in a native garden, and 3) gain first hand experience in native plant gardens, restoration, and human impacts on environments.

Why Do Organisms Vary?

Posted on November 5, 2015 by dbard

Genetic and Environmental Contributions to Trait Variation

by Beth Bastiaans and Ryan Kuntz

In this 2-month project, students design an experiment to assess phenotypic variation in one or more traits. Students use Wisconsin Fast PlantsTM (Brassica rapa). In a breeding experiment, they select a trait and analyze it during two generations of plants. Students create a pedigree by cross-pollinating the first generation with those of other students to generate a second generation of seeds with known parentage. They use linear regression to measure similarity of the selected trait in both generations. The second experiment begins with the offspring generation: students select an environmental variable, and plant enough of those offspring seeds to control that variable, again measuring the selected trait, and using linear regression to analyze effectiveness of that environmental factor.

Learning to Use Layers

by Beth Bastiaans and Dan Johnston

What factors influence roadkill densities on our streets and highways? What steps can we take to protect wildlife? In this 2-hour module, students use Google Earth to learn how Geographical Information Systems (GIS) technology can help solve environmental problems. They also develop and test their own original hypotheses about roadkill, a familiar, local environmental issue. By combining multiple GIS layers in Google Earth, students develop and test hypotheses about which other landscape features may be correlated with roadkill frequency. Finally, the students discuss the difference between correlation and causation and what factors might bias their analyses.
