Use a carbon dioxide gas sensor, a pH sensor, and a conductivity sensor to analyze the capacity of soil to support plant growth by examining the physical, chemical, and biological characteristics of different types of soil.
Students explore the requirements and capacity of soil to support plant growth by examining the physical, chemical, and biological characteristics of different types of soil.
Students gain experience conducting the following procedures on three soil samples:
Beaker, 100-mL - 4
Distilled or deionized water - 300 mL
Graduated cylinder, 100-mL
Labeling tape - 1 roll
Microscope slides and cover slips - 3
Microscope with magnification up to 400x
Microwave oven - 1 per class
pH calibration standard solution, pH 4 - 25 mL
pH calibration standard solution, pH 7 or 10 - 25 mL
Pipet, disposable, 1-mL
Plastic bags - 4
Soil samples (from 3 different locations) - 3
Wash bottle containing distilled or deionized water
White household vinegar - 4 mL
This experiment may require software and an interface for data collection.
