To better understand how solar power can aid in creating desalinated drinking water, the class creates a model still. They will build a model of a solar still, make observations, and discuss how the process works. While the idea behind...

Work on your map skills with a packet of activities about the river basins in the Democratic Republic on Congo. Learners study the maps provided before answering the geography questions and writing an acrostic poem about the region.

Students practice 12 different water color techniques and then use at least 5 of the techniques to create a painting of a landscape.

High schoolers microscopically observe various subcellular components. They determine the effects of different salt solutions on Elodea plant cells. Students explain the major function of a cell membrane and describe its structure.

Students show how constant irrigation, with repeated evaporation of water that left salts in the soil, eventually ruined much farming land in southern Mesopotamia. They discuss the idea that with the development of irrigation people...

Students observe changes in a penny when it is cleaned. In this scientific inquiry lesson, students use a dixie cup filled with vinegar and salt, and drop the penny into the water. Students observe the changes.

Students discover how salt water makes a pencil float better than freshwater by measuring and comparing the lengths of the portion of the pencil that floats above the water surface. They then determine if an unknown water sample is...

Students conduct a hands-on activity to investigate salt concentrations in water and how salt remain after water evaporates. They can also do a Saltwater Painting to once again observe the evaporation. process.

Students participate in an experiment to determine which objects float or sink. They use different amounts of salt for the objects and discover as the salt content increases, objects will float. They record their predictions and what...

Students investigate various properties of ice including melting points and the effect of pressure on ice. They demonstrate how increased pressure lowers the melting point of ice and perform a simple experiment proving that water is more...

Students study salty and fresh waters.  In this harbor estuary lesson students complete a lab activity on salinity and describe what happened. 

Students observe the effect of various chemicals on coal. Using coal, laundry bluing, water, salt, and ammonia, they observe crystal formations after a period of a few hours, and discuss their observations.

Students examine estuaries in Delaware. They, in groups, gather samples of water to find organisms and identify them.
