Compare and Contrast between different water samples
Conduct test of water quality
Interpret test of water quality data
Record information in Science Journal
Students conduct 3 tests of water quality at home that can be applied to their terraqua columns: pH, dissolved oxygen, and temperature. They make comparisons between the different types of water and make conclusions about how “healthy” each water source is for fish and other organisms. Through this process, students will practice their observational and data analysis skills. Water quality monitoring data is routinely used in the “real world” to determine the effects of habitat restoration, development, pollution, and wastewater treatment. It is usually the initial step in describing the health of an ecosystem. There are a lot of ways to extend this simple activity and make connections to the real world – from monitoring water quality in a local resacas to making comparisons between different bodies of water in our area, like the Gulf of Mexico.
