Unit 7.3 The Chemistry in Earth’s Water
This unit shows a class learning important methods in chemistry while conducting their own chemical analysis of water as part of an environmental science unit. Students engage in scientific measurements of water quality at a nearby lake.
Video program cues: 16:20-29:35

Measuring water samples

"We have a catchment lake which was built fairly close to school, we walk the kids there and take some water samples also. We do lots of stuff about chemical analysis using this lake. We are teaching filtration techniques using the dirty water samples; it could be calculating percent organic vs. percent inorganic in samples, and salt sediments."

  • The GLOBE program is a worldwide authentic science program in which students make measurements–water, land, etc–in their own locale and report the data on the web. Enter the GLOBE site and click on "Teacher’s Manual" on left for activities.
  • Activities related to the chemistry of solubility and water quality.
