the extent that the world surrenders its richness and diversity, it surrenders
its poetry...as its options diminish, so do its chances for the future."
It's a Small World After All! (Pond Microcosms)
It's a Small World After All! is actually two activities in one inquiry. In How Much Biodiversity Exists in a Pond Microcosm? students use microscopes to investigate the diversity of life that exists in pond water. In What Is the Effect of Rice on Microcosm Biodiversity? students conduct a controlled investigation to study the effect of a pollutant (rice) on a microcosm ecosystem.
Note: The best time to start this inquiry is either September or May, when pond ecosystems are at their most active levels during the school year.
