Ready for a lab with a lot of razzle-dazzle? Young chemists observe flame tests of common salts through an always-popular activity. The updated resource focuses on observation skills, collaboration, and green chemistry practices.

The trends in group 16 and the characteristic behavior of the elements involved are listed here. Their properties also help support their function. Explanations of the atomic structure and valence electron number are not included. Since...

Young chemists have unknown compounds they need to sort. Performing three different tests on each, the chemical behaviors they observe become the basis for data analysis. 

Lost an electron? You should keep an ion them. Young chemists learn qualitative analysis in the second lesson of an 11-part chemistry series. After observing reactions of simple salts, the teacher provides pupils with unknown...

After studying the different aspects of atoms and their reactivity, pupils will find this summary PowerPoint useful for review. Some of the slides are informative with labeled diagrams; others give important vocabulary. Teachers may want...
