High-quality sampling equipment does not have to break the budget. In this program, an ecologist and a biologist team up to provide step-by-step instructions on how to make four pieces of terrestrial and aquatic sampling equipment: a frame quad, for plant sampling; a pitfall trap, for sampling surface-dwelling arthropods; a plankton tow, for sampling planktonic organisms in still water; and a kick net, for sampling benthic macroinvertebrates in moving water. Then, two middle school students authoritatively demonstrate how to test the quality of water for carbon dioxide, hardness, dissolved oxygen, wide-range pH, nitrates/nitrogen, and phosphates.
