What’s in the water?
Students observe and list abiotic factors in specific ecosystems. Students will observe and list abiotic factors in an aquatic system and measure four of them (pH, dissolved oxygen, turbidity, and temperature).
Purpose: To observe and list abiotic factors in specific ecosystems.
Background:
In this activity students will observe and list abiotic factors in an aquatic system and measure four of them (pH, dissolved oxygen, turbidity, and temperature).
Physio-chemical indicators of water quality include dissolved oxygen, pH, temperature, dissolved solids, and nutrients (nitrogen and phosphorus).
Materials:
pH test kits
Dissolved oxygen test kits
Turbidity tubes
Thermometers
Copies of the student worksheet
Copies of the chemical sampling instruction sheets
Instruction Sheets
Water Quality Impact posters
Documents: Water chemistry
Presentations: Water chemistry
