There are six levels containing steps, a list of materials, graphics, and code. The guide concludes with a Total Dissolved Solids (TDS) sensor. This sensor is for testing water quality at a local pond or stream. The final project reflects the work that the NSS EPSCoR CREWS is doing in Montana.en-USThis work is licensed under a Creative Commons Attribution 4.0 International License.https://creativecommons.org/licenses/by/4.0/Learning Object
