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...

Hubbard Brook Streamflow Response to Deforestation
This teaching activity explores what the short- and long-term effects of a whole-watershed deforestation experiment are on streamflow. Students can use an MS Excel file or hard copy of data to graph short- and long-term streamflow response to a whole-watershed manipulation. Students can then compare results to baseline data, draw conclusions about hypotheses, and consider implications of...

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...

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...
