An introduction to an important group of soil and water organisms (the Oomycetes) and an opportunity to conduct some simple biodiversity exercises. This exercise can be used for all K-12 age groups and learning levels, but may be most useful for grades 7-12 in classrooms where dissecting and compound microscopes are available. It requires minimal materials (jars, popcorn, and natural water sample) and preparation.
