Forensic Tests

Lab sheets for three different crime scene investigation activities are tucked into this resource. In the first activity, inquisitors examine a variety of fibers, including the fiber found at "the crime scene," under ultraviolet light....

Scientists used flame tests to identify elements long before the invention of emission spectroscopy. Young chemists observe a flame test of five metal cations in the fourth lesson of an 11-part series. Individuals then work...

Light a fire in your pupils! Scholars conduct a flame test and observe the emission spectra of several different salts in an enlightening hands-on investigation. They use their observations to make comparisons and conclusions about the...

If you are teaching your class the metric system, and want to test their understanding, then you might consider this crossword puzzle. Learners solve the puzzle using 6 clues about the metric system. Answers not present with worksheet....

You may want to change the title of this chemistry PowerPoint to "Identifying Compounds in the Laboratory." Individual slides explain tests that can be performed to confirm what element you have: carbon dioxide, carbonates, and metal...

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...

When two liquids combine and a solid forms, the new substance is called a precipitate. Scholars test their knowledge of hydroxide precipitates and their properties. A series of four increasingly difficult puzzles challenge their logic...

How can mineralogists tell a diamond in the rough from a chunk of table salt? Science scholars find out through an interactive that demonstrates the characteristics of minerals used for identification purposes. Topics include hardness,...

This link takes you to a comprehensive unit that delves into emission spectra and supernovas. There are four parts: How and where elements are created, electromagnetic radiation, spectroscopy, and the newest technology for studying our...

Because they are reactive with air and water, scientists store alkalis in oil. Scholars complete a series of four puzzles reviewing information about alkalis. They match the alkali to its formula, the salt formed with H2SO4, and the salt...
