Curated OER
Surface Tension (Soap Boat)
Learners investigate the affect of soap and water temperature on surface tension.
Curated OER
Surface Tension and 3D Soap Films
Students are introduced to the concept of surface tension, its dependence on material composition, and how it can produce uniquely shaped surfaces.
Curated OER
What Are We?
Students list and describe three types of surface water pollutants. They observe the effects of various water pollutants on algae growth. Three causes of each surface water pollutant is listed.

Climate Patterns
Young climatologists explore the factors that contribute to a region's climate in this two-part earth science activity. To begin, learners are provided with a map of an imaginary planet and are asked to label global wind and...
Curated OER
Where in the World Is All the Water?
Students investigate the distribution of the earth's water. They conduct a demonstration of water distribution, and create a pie graph to display the results.
Curated OER
Global Water Crisis
Young scholars research a given nation and complete an activity chart for that country. For this water crisis lesson students work in groups to organize and present the information for their given country.
Curated OER
The Water Cycle
Students develop a better understanding of the need to conserve our renewable resources. In this water cycle lesson students take notes, complete a guide sheet and illustrate the water cycle.
