Water Pressure in the Ocean
Students compare the pressure of water at different depths and gain an understanding of how increased water might affect animals living in deeper waters. They participate in an experiment to show that depth, not volume, affects water...

Testing Water Quality
In this science learning exercise, students test the quality of water taken from a local source and test it in a lab for the ingredients present.
Curated OER
Condensation and the Water Cycle
Students explore the natural distallation process that occurs in the water cycle. They use plastic cups and cotton swabs to observe the condensation process that is evident in the water cycle.
Curated OER
Water Purification
Students develop an understanding and appreciation of water purification techniques and their implications for health maintenance.
Curated OER
Water Pollution
Students study four samples of "rain water". They asked to determine the pH of the samples and then to neutralize them. Students are asked to predict any negative effects which might be associated with water having a low pH and to...
Curated OER
Testing Water for Hardness
Students discuss the nature, cause and effect of hard water. Each student conducts a soap test on a sample of hard water where the hardness is known measuring the height of the bubbles produced.
Curated OER
Rock Hounds
Young scholars receive a basis for understanding the three main classifications of rock: igneous, sedimentary and metamorphic. They engage in a hands-on activity designed to give them an appreciation for rocks and minerals.

Red Cabbage Chemistry
Using the natural pH indicator of red cabbage juice, groups determine the pH of different everyday liquids. As they work, pupils gain an understanding of pH that may help deal with contaminants in the water supply.
Curated OER
Water Quality
Students play the role of scientists testing for water quality in the area. In this ecology lesson, students determine the water sample's pH, temperature, dissolved oxygen and turbidity. They write a journal reflection after the activity.
