  • Thermal and Chemical Pollution
    Thermal & Chemical Pollution

    Using yeast to represent oxygen consuming microorganisms or animals, the effect of temperature on biological oxygen demand and dissolved oxygen in water is explored, relating this to the metabolism of an organism. Further activities investigate chemical pollution by direct poisons (lead irons) and indirect (phosphate ions) that disrupt what lives in water by favoring the growth of one type of organism.

  • How Poisons Work
    How Poisons Work

    This kit is designed to teach students that the life of a cell depends upon the activity of specialized molecules called enzymes, which may be disrupted by the presence of poisons. Activities are included to permit observation of normal and abnormal conditions affecting enzyme activity. The effects of heavy metal poisons (lead and mercury ions) on enzyme activity are observed.

  • How Clean Is The Soil
    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.
