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...
Curated OER
Worksheet 4-1 Atomic Spectra
In this atomic spectra worksheet, students answer eighteen questions about wavelengths of light, the emission spectrum, energy of photons, the frequency of electromagnetic radiation and electrons in the excited state.
Curated OER
AP Chemistry Atomic Structure-7 Worksheet
In this atomic structure worksheet, students solve twelve problems related to wavelength, frequency, electron transitions, emission spectra and quantum number.
Curated OER
The Day the Atom Died (Grade K-1)
Students investigate what is wrong with the Rutherford atomic model. In this chemistry lesson, students answer questions about the atomic model after watching a video. They draw conclusions from the video and discuss how the atomic model...
Curated OER
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.
Curated OER
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.
