Featured in PASCO’s Biology through Inquiry Teacher Guide
Features 25 inquiry based labs covering the fundamental concepts of cell biology, ecology and physiology.
Use a pH sensor to understand the effectiveness of various treatments for improving the quality of water.
Guide students to understand the effectiveness of various treatments for improving the quality of water.
Using a pH sensor and a conductivity sensor, students gain experience conducting and comparing the following procedures:
- Measure a sample of polluted water to establish a controlled reference.
- Measure the water sample after applying sedimentation only.
- Measure the water sample after applying sedimentation and filtration
- Measure the water sample after applying coagulation, sedimentation, and filtration.
Sensors / Equipment Used:
Measures temperature, conductivity, pH/ISE/ORP and dissolved oxygen. It is specifically designed for convenience in conducting water quality lab experiments. For use with PASPORT Interfaces.
