Curated OER
Water Quality
For this water worksheet, students determine the factors that effect the solubility of gases, calculate the percent concentration of solutions, and give the balanced chemical equation for photosynthesis. This worksheet has 18 short...
Curated OER
"Pennsylvania Watersheds, Many Ways to the Sea"
Students trace a molecule of water through the water cycle including each of its three loops. They describe why evapotranspiration demands the largest portion of total precipitation falling on a forested watershed.
Curated OER
Teaching about Aquatic Respiration
Students 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
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.
Curated OER
What Are We?
Students 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
Pupils 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
Students 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...
