Couches, carpets, and even computer keyboards now advertise they are spill-resistant, but what does that mean? Scholars use physical and chemical methods to coat surfaces with thin films to test their hydrophobic properties. Then they...

In this chemistry worksheet, students examine the elements and focus on things like the mass and order for the location to match with the type of elements.

Eleventh graders examine the history and development of the periodic table and properties of elements. They complete worksheets, take notes during a teacher-led discussion, and produce their own periodic table.

Students explain how elements are arranged in the periodic table. In this chemistry lesson plan, students group the eggs according to a certain pattern. They compare this to elements in the periodic table.   

Students study the meaning of a water table and how it contributes to the existence of streams, swamps, and lakes in Nebraska. They conduct an experiment and complete a diagram of the hydrologic cycle.

In this reading tables worksheet, students use the table to solve the problem. Students may draw or write to explain their answer in the provided space.
