Discusses the different varieties of rice and how these differences are important in cooking and health. Discusses the cultural and historical importance of rice. (YDS)

Explains the redux chemistry of the experiment of cleaning pennies with a vinegar-salt solution. (Contains 12 references.) (YDS)

Uses a Galilean thought experiment to enhance learning in a college-level physical science course. Presents both modern and historical perspectives of Galileo's work. As a final project, students explored Galileo's thought experiment in the laboratory using modern detectors with satisfying results. (Contains 25 references.) (Author/ASK)

Presents hands on science activities using toys on the topics of average speed, acceleration, wavelength, and bouncing balls. (YDS)

Uses a teaching approach in which students prepare their own physics activity lesson plans and use them in class with other students. (YDS)

Presents an activity in which students act like real-estate agents who market their planets as a great place to live. Evaluates students on their presentations. (YDS)

Presents a science laboratory using different brands of potato chips in which students test their oiliness, size, thickness, saltiness, quality, and cost, then analyze the results to determine the best chip. Gives a brief history of potato chips. (YDS)

Summarizes the recent research on pollen germination and introduces some basic studies on pollen tube growth that can be conducted in a secondary school laboratory. Discusses the use of a light microscope and refrigerator to study pollen. (Contains 13 references.) (Author/YDS)

Rx values in thin-layer chromatography (TLC) depend strongly on the solvent saturation of the atmosphere above the liquid in the TLC developing chamber. Presents an experiment illustrating the potentially dramatic effects on TLC Rx values of not equilibrating the solvent atmosphere during development. (ASK)

Presents an activity that explores the temperature behavior of UV-sensitive beads and investigates the effectiveness of sunscreens. (ASK)

Reports on studies of students with severe learning difficulties and shows that they could, under appropriate conditions, display impressive concentration and curiosity, and often appeared to achieve valuable learning. Describes some of the dilemmas that may arise in developing these kinds of activities for special education. (Contains 35…
