Describes a laboratory project for first-year biology students that examines competition among various cellular slime molds. After a brief introduction to the topic of competition and basic life history information about cellular slime molds, students choose a question and design original experiments to seek an answer. (Author/AIM)

Describes an approach for making chemistry relevant to everyday life. Involves the study of kinetics using the decomposition of hydrogen peroxide by vegetable juices. Allows students to design and carry out experiments and then draw conclusions from their results. (JRH)

Presents experiments with polarized light for grades 8-12 which can produce colorful effects with a minimum of equipment and can illustrate many principles of physics, chemistry, and geology. (MKR)

Describes an experiment designed to measure absolute zero using Charles' Law without the use of mercury. Provides the procedure and details of the apparatus and includes experimental results obtained using the apparatus. (DDR)

Describes a university outreach program that aims to enable teachers and students to learn the content and process of modern scientific inquiry by engaging in research and communicating their findings to others. (DDR)

Presents a set of activities for testing consumer products to encourage students to learn how to use scientific investigations in their everyday lives. Describes the penny flip experiment and testing a detergent. Students learn in a hands-on manner the importance of completing accurate laboratory reports, which allows them to analyze results and…

Presents an experiment that is quick and easy to prepare, visually striking, and amusing to students. Relates to several key chemical concepts including polarity, intermolecular forces, solubility, and spectrophotometry. (Author/NB)

This article gives examples of science teaching for gifted students from the Young Persons' Institute for the Promotion of Art and Science in Tel Aviv (Israel). Emphasis is on fostering curiosity and experimentation. Examples are offered in teaching about the weather, water, and light and color. A model experiment to teach electricity principles…

Describes a science and math activity that involves bubbles, shapes, colors, and solid geometry. Students build geometric shapes with soda straws and submerge the shapes in soapy water, allowing them to review basic geometry concepts, test hypotheses, and learn about other concepts such as diffraction, interference colors, and evaporation. (TJQ)

Describes two variations of an air sampler and analyzer that are inexpensive to construct, easy to operate, and designed to be used in an educational program. Variations use vacuum cleaners and aquarium pumps, and white facial tissues serve as filters. Samples of air pollution obtained by this method may be used from early grade school to advanced…

Describes the scientific work of several women, including Marie Curie, Lise Meitner, Ida Noddack, Irene Curie, Marguerite Perey, Chien-Shiung Wu, and Maria Mayer. Discusses the connections between their discoveries. Thirty-six references are listed. (YP)

Described is an activity in which students are able to determine that DNA can be transferred between bacteria and should be able to predict the type of DNA transferred. Methods, materials, and results are discussed. (CW)

Provides historical background, descriptions, uses and basis for identification of diatoms. Explains collection, dry-mount cleaning, and preparation procedures of the algae. Cites additional resources. (RT)

Describes an alternate method of demonstrating thin film interference fringes with a laser by using a microscope slide glass cover. (MKR)
