Build a Plankton Net
Give household materials new life by turning them into a plankton net. Scholars design and build a net to collect and filter plankton from water. They test out their creations by using glitter to represent plankton. The nets need to...
Curated OER
Straining out the Dirt
Young scholars design and construct a water filter using activated carbon, cotton and other materials to remove chocolate powder from water. They test and record their observations, and complete a KWL chart.
Curated OER
A Tool for the Environment
For this desalting salt water worksheet, students will read about three different methods of desalting sea water which includes distilling, crystallizing, and filtering. Students will describe these methods in three short answer...

What are the Chemical and Microbiological Effects of Run-off from a Catfish Pond on the Surrounding Soil and Water?
Students study data from a USDA catfish pond. They look for microbial populations and chemical concentrations in the runoff to determine the effectiveness of filter strips. They use their knowledge of biogeochemical cycles to explain the...
Curated OER
Diffraction of Laser Light, Polarization and Color Filters
Students investigate light behavior by conducting a series of experiments. In this physics lesson plan, students calculate the wavelength of the light source using an equation. They determine what color is produced when light of...
