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!
How many of you could recite, word for word, a definition you learned in school? When you first memorized the definition, you could state “inertia is a property of matter”, or “density is mass over volume.” However, you struggled to apply it to a new situation and maybe you were unsure of how to construct a model of what it meant.
In this Activity, students use written clues to determine the identities of 12 chemical compounds. They write the name and chemical formula for each compound, and find a consumer product in which each compound is present. This Activity increases student awareness of the presence of a variety of chemical compounds in a range of common consumer products.
