Curated OER
Teaching about Aquatic Respiration
Learners explore respiration in a lake ecosystem by experiment and research.
Curated OER
Discovering The Oasis
Students participate in a lesson that is concerned with the ecosystem of a local pond. The teacher makes arrangements for students to take a field trip. Time is spent in class for preparation and afterward for debriefing of lab...
Curated OER
Sustaining Life Under the Ice
Pupils 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.
Curated OER
What Are We?
Pupils describe different types of water pollutants. They complete experiments in which they observe the affects of water pollution on algae. They also brainstorm and list three causes of each water pollutant.
Curated OER
All Messed Up
Students begin the experiment by mapping and calculating their school parking lot. They calculate the volume of water falling on the lot and map the route the water runoff takes. They discuss the roles that humans play in affecting water...
Curated OER
Chesapeake Bay Population Studies
Pupils determine how to use a quarter meter quadrant to find population density, relative density, frequency and how to calculate a diversity index while participating in a virtual field trip. They study how to establish a Correlation of...
Curated OER
Water Purification
Young scholars develop an understanding and appreciation of water purification techniques and their implications for health maintenance.
Curated OER
N, B, and T: Pollutants Three
Students explore nutrient, bacterial, and toxic surface water pollution. They identify the amount of water they use each day and summarize the kinds of substances that cause water pollution. They predict what will happen in water...

Science Buddies: Harmful Algal Blooms in the Chesapeake Bay
Harmful algal blooms occur when algae, which form the base of the ocean food web, grow in massive numbers and produce toxic or harmful effects on people, fish, shellfish, marine mammals, and birds. In this project you will learn how to...
