They're Everywhere: Bacteria
Author(s): Nancy Moreno, PhD, and Barbara Tharp, MS.
- Design additional experiments to test for the presence of bacteria. For example, students can test bacteria levels in water from different sources. Or, they can conduct and experiment to see which kinds of food grow the most kinds of bacteria or become spoiled most quickly by bacteria.
- Have students investigate two similar samples, with one sample grown at room temperature and the other grown in a refrigerator.
- Have students do research in the library or on the Internet to answer the question, “How many good uses of bacteria can you find?”
