Featured in PASCO’s College Environmental Science Instructor Guide
College Instructor edition with experiments covering introductory and general environmental science topics.
Use pH, conductivity, and turbidity sensors to demonstrate how water treatment processes such as filtration, flocculation, and sedimentation improve water quality.
Students demonstrate how water treatment processes such as filtration, flocculation, and sedimentation improve water quality.
Students will gain experience conducting the following procedures:
Activated charcoal - 2 g
Balance - 1 per class
Beaker, 150-mL - 4
Beaker, large ("wastewater" container)
Graduated cylinder, 100-mL
Graduated pipet, 50-mL, and bulb
Lint-free lab tissue box
Paper napkins, dinner, white, smooth - 12
Paper towels, white - 4
Soda bottle, empty, 500-mL
Swimming pool water clarifier solution, 4% - 2 to 4 mL
Test tube, 18-mm OD or greater
Wash bottle containing water
Wastewater sample (made from coffee, soil, and kitty litter if the soil has a low clay content) -500 mL
Water - 300 mL
This experiment may require software and an interface for data collection.
