Curated OER
Teaching about Aquatic Respiration
Students explore respiration in a lake ecosystem by experiment and research.
Curated OER
Sustaining Life Under the Ice
Students design and conduct experiments in order to identify the components of lake water environments that are affected by winter ice cover. They use the experiment results to propose effective human management of these ecosystems.
