View Resource Pathways to Scientific Teaching, Chapter 5c of 7: Unleashing problem solvers: from assessment to designing research

Can transgenes be kept on a leash?” ask Marvier and Van Acker in the [attached] review article. “No”, they answer, “the movement of transgenes beyond their intended destination is a virtual certainty”, and furthermore “it is unlikely that transgenes can be retracted once they have escaped”. Would these bold statements engage students, revealing the realities and complexities of gene...

View Resource Leaves as Thermometers

Plant morphology reflects evolutionary solutions to environmental constraints. In this experiment, students use this principle to predict the climate at their site. They collect and measure a set of traits on local tree leaf samples during the first meeting. At the following meeting(s), they pool their data and are introduced to a global database of climate and leaf morphology. In groups, they...

View Resource Processes that Regulate Patterns of Species and Genetic Diversity

During a single lab period, students simulate colonization and drift in artificial communities to understand how these processes affect distributions of biodiversity in small versus large communities with varying degrees of isolation. Plastic bins represent islands, and are situated to represent different degrees of isolation. Ziploc bags of candy represent individuals in the communities and...

View Resource The Cow Diversity Project: introducing undergraduates to molecular population genetics

This is a multi-week laboratory exercise that involves sequencing a pair of mitochondrial genes in cows. Using data from several samples, students calculate diversity (variation within species) and divergence (variation between species). The exercise reinforces principles in molecular genetics (DNA purification, PCR, etc.) and introduces principles in molecular population genetics. We provide...

View Resource Activity: Using Soil Fungi Next Generation Sequencing Data to Study Wildfire Resiliency

This lab exercise is an active learning introduction to techniques used to analyze soil microbiome data. Students will also learn about forming hypotheses, what kind of questions can be answered with this data, and practice the scientific method. This resource was developed with support from the National Science Foundation.
