In this Experiment, students make impressions of leaf stomata (using clear nail polish) and test a hypothesis of their choice about how leaf stomata density might vary under different environmental...
This Issue focuses on a research article by Blaustein and Johnson (2003) that was published in Frontiers in Ecology and the Environment. The article discusses amphibian deformities, which may be...
During this exercise students will explore plant diversity in a greenhouse facility to investigate the evolutionary adaptations that have allowed plants to survive in a diversity of habitats....
In this TIEE dataset, students answer the question of whether nutrient cycling (excretion) rates of fish in lakes scale with body size and temperature as predicted by The Metabolic Theory of...
In this Experiment, students investigate the effects of ecological factors on the growth of Wisconsin Fast Plants, also known as rapid-cycling brassica (Brassica rapa L.). Treatments could include...
