These sites focus on acids and bases. Learn the difference between acids and bases and their chemical reactions. There are activities and experiments that help students to learn how to use pH scale and to classify materials as acids, bases, or neutral. There are virtual experiments, interactive games, experimental ideas, animated movies, and quizzes. Includes a link to eThemes Resources on mixtures and solutions.
Learn how acids, bases, and alkalis have chemical reactions on metals. Includes examples of acids and bases found at home and their uses in daily life. There is also an interactive experiment and a test at the bottom of a page. NOTE: This site contains a link to a message board.
In this virtual experiment, students will identify if items found in the kitchen are base, acid, or neutral. They will also learn to recognize that a mix between acids and baking soda will produce carbon dioxide.
Scroll to Chapter 5 "Chemical Change" for downloadable activities on chemical reactions and acids and bases levels identification in substances. Includes molecular animations for the investigation. Student Activity Sheets and the entire chapter can be downloaded and printed. NOTE: This site has a link to discussion boards.
These sites provide information about the chemistry of mixtures and solutions. Learn what mixtures and solutions are made of, what their properties are, how to separate components of mixtures, and methods of separation. There are examples of mixtures encountered in daily life, classroom activities, experiments, interactive games, and animations. There is a link to eThemes Resources on Chromatography.
