Various types of puzzles are widely used in STEM learning activities due to their ability to familiarize students with given content using a strategic approach. In this novel puzzle, there are two steps to complete the exercise. The first step involves the participant identifying periodic table element abbreviations within a specific word. The second step involves fitting the corresponding element names into a blank crossword format. The students become familiar with the elements and their abbreviations, as well as their location on the periodic table.
Beautiful, metallic mirrors of copper or silver can easily be formed in test tubes. Simply add the appropriate metal salt to a test tube, and heat! These reactions should be performed in a fume hood.
Learn how to form a blue-green copper compound on a penny, and then use that compound to make green flames. This is a great summer time activity for your next campfire!
