Biology and Chemistry of Soil Experiment

kit #32

Time to play in the dirt! Students use ordinary soil samples to conduct a thorough evaluation of soil. Simple, easy-to-follow techniques and staining procedures are introduced early in this series of activities. After performing a series of activities, students are asked to draw conclusions concerning a soil’s ability to support plant growth. All tests are performed using either the patented Chemplate or calibrated sample tubes.


  • Conduct a thorough evaluation of soil
  • Identify the type and variety of micro-organisms (soil microbes)
  • Calculate soil fertility by a cation exchange capacity elimination
  • Test and determine soil pH
  • Correlate the soil's pH value to soil lime requirements
  • Develop and use stain technique and microscopes
