Compounds take on different properties than their elemental components. How can scientists determine those elements? A lab-based activity has learners explore several double replacement reactions to analyze compounds qualitatively. They...

Colorful lead compounds never fail to impress! Solubility scholars examine a series of double replacement reactions involving lead nitrate and record their observations. The second part of the experiment illustrates the differences...

You're bound to get a reaction from your classes with this experiment! Scholars perform several chemical reactions, make observations, and classify the reactions as single replacement, double replacement, composition, or decomposition...

Chemistry and physics combine forces to benefit nanofabrications. Learners examine the process of wet etching in nanofabrication. Using corrosive substances such as lemon juice and Coca-Cola, they model the etching process. They then...
