In this activity, students work with data collected during 15 years as part of a long-term research project at Harvard Forest. Students analyze the data to address the question, "How have stands of pine and hardwood forest responded to long-term nitrogen fertilization?" Students address the question using data on several ecosystem characteristics and processes: net primary productivity, tree...

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...

In this simulation, students work in groups to design a marine reserve in a hypothetical island state called “Udubia.” After learning about marine reserve design, students will choose characters that represent a variety of stakeholders, be placed in like-minded groups, create a reserve design based on provided data sources, and defend it in a presentation and debate. An optional individu...

In this TIEE data set, students answer the question of what influences flux of nitrogen from catchments underlain by discontinuous permafrost. Students work with a large dataset describing nitrogen dynamics in the Caribou-Poker Creeks Research Watersheds, small watersheds in the boreal forest that are underlain with various extents of permafrost cover. Students use spreadsheet and graphics...

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...
