Testing the Waters
Students study the quality of water by running chemical tests on the water. First, they measure pH, temperature, phospates, and nitrates in tap (drinking) water and an outdoor water sample. Then they post and evaluate the results of...

Teaching about Increased Conductivity: Are Culverts The Culprits?
High schoolers encounter the complexity of identifying the cause of unusual variations in WOW conductivity data. They propose theories on why there was a sudden increase in conductivity in Ice Lake, Minnesota during July of 1998.

Teaching about Aquatic Respiration
Students explore respiration in a lake ecosystem by experiment and research.
Curated OER
Teaching about the Chemistry of Oxygen Solubility
Students explore solubility of gases in water, Henry's Law, LeChatelier's Principal, and supersaturation of gases in water.

Specific Heat of Metal
Students experiment with different types of metal by dipping them in boiling water and cool water and recording temperature changes in the water. By doing this, they find the specific heat of the metals.

Air, Air Everywhere! Lesson 2: Acid Rain
Middle school environmentalists record the pH of four different liquids, including two aerosol cleaning products. They liken the products to acid rain and speculate in writing which might affect the human respiratory system. Although...
