View Resource A quantitative investigations of plants expressing green fluorescent protein (GFP) using a home-made camera attachment

In this laboratory exercise students use digital cameras to measure surface fluorescence of transgenic plants expressing green fluorescence protein (GFP). Inquiry pedagogy is used to teach processes used in scientific investigations and how GFP is used in reporter gene systems. Students start by making observations involving induction of expression of a GFP expressing reporter gene and then...

View Resource A Structured Inquiry Approach to Cotyledon Phenotyping

Transmission genetics labs are valuable for undergraduate development of analytical thinking skills. However, these labs typically present the scientific process as artificially linear, with a single "right answer." This resource describes an inquiry-based approach to teaching a transmission genetics lab focused on plant cotyledon color. Student groups are required to develop a hypothesis based...

View Resource Simulating Sampling Communities and Calculating Diversity Indices with Scrabble Game Tiles

Using tiles from a Scrabble game, we present methods to create simulations of sampling exercises and to develop diversity indices. The tiles represent species, and so a known sampling universe (100 tiles) allows comparing a sample with the known distribution of species. We then offer several variations to simulate different kinds of sampling (larger sample size, more samples), alter the rarity...

View Resource To Plant, or Not to Plant? Regulating Invasive Plant Species in the Mid-Atlantic States: A Social-Ecological System Case Study

As invasive plant species spread across landscapes, costs of their economic and environmental impacts have sparked interest in regulating their sale and transport. Laws now prohibit the sale and movement of some species. State and local governments are drafting regulations that will affect horticulture, plant nurseries, and options for landscape design. Awareness of invasive plant species is...

View Resource Life Cycle Analysis and Assessment of Crop Production Methods

Students use their ecological knowledge of soil processes, energy, water systems, and human interactions to compare the environmental impact of food production. Each group of 3-4 students develop life cycle analyses (LCA) for a single crop grown under different scenarios. As individuals, students are responsible for developing two LCA for that crop, and then together in their groups, they compile...
