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 what kinds of soil in the local community would support agricultural crops, based on pH level.
Guide students to understand what soils, in their local community, would support agricultural crops, based on pH level.
- Record detailed observations about the environment where the soil samples were taken.
- Determine and compare the acidity or alkalinity of each soil sample.
Students gain experience conducting the following procedures:
- Gather soil samples from different locations in the area and record detailed observations.
- Measure the acidity or alkalinity of three different soil samples using a pH sensor.
Sensors / Equipment Used:
Has a wide measurement range of 0 to 14 pH. Has a resolution of 0.01 pH. For use with PASPORT Interfaces.
Allows an additional two meter length extension on all PASPORT sensors.
