Flame Tests and Emission Spectra

The University of the State of New York has designed a series of exams for high schoolers. This chemistry exam is one of the most comprehensive and well-written that you will ever find. It consists of 84 questions in a variety of styles,...

When given too much data to simply memorize, it helps to sort it into manageable groups. The second lesson in the six-part series of Cosmic Chemistry challenges groups of pupils to take a large amount of data and figure out how to best...

Students investigate the spectroscopic colors unique to elements, and to use this information to create a specific color. They follow a detailed schematic to produce a spectroscpoe to be used in the testing.

Space scientists investigate the cosmic phenomena in order to search for answers to possible origins of the solar system. They consider the concepts of elements and  isotopes. Data is analyzed looking at tje abundance of elements...

Young scientists use electrolysis to separate water into its elements before experimenting with fire to learn about their properties. A helpful resource provides a reading passage and analysis questions. 

This short presentation provides a convenient introduction to the nitrogen group in the periodic table of elements. A graphic displays where they are placed in the periodic table. The nitrogen cycle is mentioned and ammonia is explained....

The ten slides in this presentation make a consice introduction to the halogen group of the periodic table of elements. The location of the group is displayed, and then the characteristics of the different halogen group members are...

Scientists identify elements by the color of flame they produce because each element is defined by exactly one line on the emission spectrum. By completing a series of puzzles, scholars reinforce their knowledge of the results of flame...

The periodic table can be a little overwhelming to young scientists. Meet your class' worries head on by introducing the table in a game. Individuals test their knowledge of the names and symbols of common elements, then use deductive...

Many pupils mix up the chemical symbols for calcium, carbon, and copper. These entertaining puzzles help scholars remember the names and symbols. First, they match the name and symbol of 12 elements. Then, through a series of three...
