Polymers as Straws Lab

Your class will work with a water-absorbent polymer to study its properties under various conditions. They'll measure the polymer absorption characteristics with various solutions while exploring the factors which impede absorbency. In the process, students will learn how to calculate absorbency ratios. They will then apply their results and conclusions to various commercial applications of these long-chain molecules. They'll also relate their findings to processes in living cells, such as osmosis.

Includes enough materials for a class size of 40 students. Recommended for students in grades 7 through 10. Manufactured by Neo/SCI.
