Student Test Kit
  • Chemical Composition of the Soil

    Permits students to perform chemical determinations on locally derived soils to determine percentage of water, organic content, pH, and the presence of calcium, carbonates, magnesium, phosphates, sulfates, potassium, nitrate, ammonium and iron. Provides an accurate profile of the chemical nature of the soil.

  • Microorganisms in the Soil

    With this kit students are able to culture soil samples from local sources to observe the nature of soil microbes. Students investigate the nutritive and non-nutritive components in the soil samples. A dozen pairs of students have materials for one 45-minute class period to be followed by observations over the next three to four days.

  • How Clean Is The Soil

    This kit encourages students' investigation into the nature of soils. Soils are observed and characterized based on physical examination. The chemical composition is examined and the microbial community studied. The kit is intended for a demonstration, or small groups, or several repetitions for an individual investigator and will require two 45-minute class periods.

  • How Soil Is Formed

    This kit is designed to give students in natural science courses an understanding of the forces involved in soil formation. The students will simulate a series of physical, chemical and organic processes that are involved in rock breakdown. The materials and experiments in the kit are suitable for junior and senior high school level students, as well as more advanced elementary school classes. Activities are designed for a class of 30 working...
