Describes the chemical reactions and compounds involved in making a cake. A protein coagulation and gas expansion laboratory activity is included in which the students bake a cake and eat it. (DS)

Presents activities for the fossilization process by using rust prints to simulate fossils. Photographs illustrate the procedures described. (HM)

Describes historic aspects of color or coloring. Presents activities involving spectral colors identified by Sir Isaac Newton and others involving dyes and dyeing. (MKR)

Presents an activity that demonstrates the physical and chemical changes that occur during the operation of a wet cell battery as it produces an electrical current. Provides instructions for the lesson. (MDH)

Provides activities that explore the concept of solubility using correction fluid. Topics include oil versus water solubility and whole milk versus fat-free milk. (DDR)

Describes some inquiry-based labs in which students identify starch in popped popcorn, then determine whether starch is present in the kernels prior to them being cooked. Students distinguish monocot and dicot stems as well as determining whether boiling kills tissues in seeds that have been soaked in water. (DDR)

Discusses the nature of light-producing reactions and provides a procedure for demonstrating chemical luminescence using siloxene indicator. Indicates source of this chemical and safety precautions. (SK)

Describes the construction of a simple apparatus that can be used to take advantage of the overhead projector in a spectacular presentation of chemical reactions that complement quantitative approaches of study in the traditional high school science classroom. (JRH)

Describes science activities used in an eighth grade class such as metric measurement exercises, classification problems, experiments with batteries and bulbs and a series of activities concerning chemical reactions. (BR)

Describes a simulation of chemical reactions to help students understand factors that affect the rates of chemical reactions. (PR)

Presents an approach that can help students to understand what happens in an experiment. Uses overlapping transparencies of both the experiment and the analysis. Includes details of the experiment and transparency preparation. (DDR)

Describes an activity that allows students to actually hold a chemical reaction in their hands as it occurs. Enables students to experience the release of energy by a reaction first hand. (JRH)

Discusses the basic principles of baking soda chemistry including the chemical composition of baking soda, its acid-base properties, the reaction of bicarbonate solution with calcium ions, and a description of some general types of chemical reactions. Includes a science activity that involves removing calcium ions from water. (LZ)

Presents four activities that involve chemical reactions with vinegar, lemon juice, or orange juice. These activities can be used to teach about acid-base reactions and acids as chemical catalysts. (WRM)
