Chemistry Science Fair Projects Using Acids, Bases, Metals, Salts, and Inorganic Stuff — Robert Gardner

Published by Enslow Publishers, 2004.

You’ll find all kinds of neat science fair projects involving chemistry in this book, which is divided into five chapters. The first, “Identifying Substances,” discusses boiling, freezing, density, and separating mixtures, while the second chapter discusses conservation of matter. “Some Chemical Reactions and Their Reaction Speeds” has experiments about rust, oxygen, and the rate at which hydrogen peroxide decomposes. In “Energy in Chemical and Physical Changes,” you’ll look at energy, heat, and condensation. The last chapter features projects about acids, bases, ions, and building an electric cell.

Power Words

catalyst A substance that starts or speeds up a chemical reaction between other substances. Catalysts are not changed by the chemical reactions they are involved in. Certain molecules in saliva are catalysts that help us digest food.

electrolyte A substance that can conduct electricity in a solution. An electrolyte’s atoms get their electric charge by adding or giving up electrons. The movement of these charged atoms, called ions, carries the electric current.

fuel cell A device that uses a chemical reaction to make electricity. Fuel cells are used in space shuttles, where they create electricity by combining hydrogen gas with oxygen.

platinum A silver-white chemical element that is a soft metal. Platinum has a high melting point and does not rust. It is used in jewelry and as a catalyst.

polymer A chemical compound that is made up of a chain of smaller molecules. Cellulose is a polymer that occurs naturally in plants, and nylon and acrylic are polymers that scientists have created in the laboratory.
