In this activity, students work with a dataset to investigate energy balance in animals that have different feeding behaviors (diurnal/nocturnal) and diets (e.g., carnivore/detritivore).

In this activity, students conduct an experiment to test a hypothesis about how freshwater snails detect and avoid fish predators using chemical cues and habitat complexity. Students generate a hypothesis, run the experiment, collect data, analyze data, and interpret their results. Instructions are also provided for further thought and discussion on the implications of the students' findings and...

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 Ecology. Students use data on the nitrogen and phosphorus excretion rates of fish to test hypotheses related to metabolic ecology.

In this TIEE experiment, students investigate the costs of reproduction. In dioecious plants, a female's investment in reproduction is typically much greater than a male's, because while both sexes encounter the basic cost to produce a flower, only females have to allocate energy to seeds, exceeding the energy requirements to produce pollen. This 1-2 week field project tests whether the effects of...

In this TIEE experiment, students investigate how ambush predators such as the common ambush bug (Phymata americana) or the common crab spider (Misumena vatia) influence the foraging behavior of insect pollinators on flowers. This project involves an experimental manipulation of predator presence and subsequent pollinator observation over the course of a single or several lab periods. Students...
