Atomic Emission Spectra and the Bohr Model of the Atom
High schoolers investigate the wavelengths of spectra lines for common atoms. In this atomic emission spectra lesson plan, students use a transformer and diffraction grating to observe the emission spectra of various atoms. They find the...

Atomic Absorption Determination of Zinc and Copper in a Multivitamin
Advanced lab apprentices prepare zinc and copper solutions to which they will compare the same minerals from a multivitamin. Using absorption spectroscopy, they analyze the contents of the multivitamin for concentration. This lab can be...

Flame Test
Students conduct a flame test on different substances. In this chemistry lesson, students predict the element present based on the color emitted during the flame test. They explain how different elements produce different colors.

History of the Periodic Table
Students sort a group of manipulatives and then explain their organizational system to the class. They discuss the work of scientists trying to organize the elements into a system that made sense and the development of the periodic table.
