​​Stream Study Equipment

There are many excellent science and environmental equipment vendors in the market today. While for some types of equipment the difference between products is slight, for others there can be substantial differences. Please always read the safety hazards and protocols for each piece of measurement equipment so you know the potential hazards BEFORE going out into the stream with students. This is particularly important in regards to the chemistry kits needed to assess certain water quality parameters.

A fun and challenging option to consider is having students make their own stream monitoring equipment. This integrates an engineering component into the unit of study as well as allowing students to adapt the equipment according to their needs. pdf iconClick here to make your own monitoring equipment.
