Where Do We Get Clean Water?
Students investigate the concept of a filter. They use simple supplies in order to construct one after watching a demonstration performed by the teacher. An important warning that the project water is not clean for drinking is included....
Curated OER
Water Quality Tests Explained
Students define all eight water quality parameters and list at list one source for each of the eight water quality parameters. They determine how each of the eight parameters affect river ecosystems.

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
Life in a Drop of Water
Students examine the structure, function, and characteristics of microscopic organisms that inhabit freshwater through collection of water samples and observation through microscopes.
Curated OER
Water Cycle in a Bottle
Students study the water cycle. In this water science lesson, students complete a water cycle experiment using soda bottles.
Curated OER
Water Cycle Column
Students use common materials to construct a working model of the water cycle. They then observe and explain evaporation, condensation, precipitation and percolation as aspects of a continuing cycle. Students also complete worksheets and...
Curated OER
Water Quality Monitoring
Young scholars study the water quality of a stream in their area, by measuring the temperature, pH, alkalinity and conductivity. They integrate biology with earth science when using the microscope to study the living organisms in the water.
