View Resource Enhancing science teachers' understanding of ecosystem interactions with qualitative conceptual models

The project described in this article explores how a series of conceptual ecological models can be used to portray the improvement in ecological understanding over the span of a short course. The course involved high school teachers working collaboratively on ecological research projects. Teachers were asked to construct qualitative conceptual models (a diagram of important ecosystem components...

View Resource Using Stream Leaf Packs to Explore Community Assembly

In this TIEE experiment, students will explore functional and taxonomic diversity in a stream ecosystem, learn about food web relationships, and learn about the ways in which abiotic and biotic factors determine what organisms are present in a community. Students will make and install artificial leaf packs in a stream, wait for the leaf packs to be colonized by stream organisms, measure...

View Resource Comparisons of Mycorrhizal Properties from Two Host Tree Species

In this lab experiment, students learn about ectomycorrhizal (ECM) fungal properties associated with two host tree species to better under understand symbioses in general and gain experience using soil sampling and mycorrhizal field methods. Students will learn in more depth about terms and concepts related to symbioses (e.g. mutualisms, coevolution, host specificity) and about specific...

View Resource Effects of multiple invasive species in experimental aquatic communities

In this exercise, students first work in small groups to collect background information on what mosquitofish and bullfrogs consume and then modify a food web based on that knowledge. Students then develop hypotheses of how these two invasive species may affect native amphibian species, snails, and zooplankton. Following, students work individually to analyze experimental mesocosm data to determine...
