Water Quality
Learners observe water samples and measure the samples' water quality. Young scholars develop their own criteria for measuring water quality and test for temperature, acidity, oxygen levels, turbidity, conductance, sediment and hardness.
Curated OER
Making Clean Water
Students examine water samples assess the quality of each sample by examining the color/clarity, smell, pH, etc. of each Then they filter the water samples once and assess water quality a second time. finally they filter the samples a...
