Describes the Connecticut Academic Performance Test (CAPT) and explains the reasons for a curriculum change. Introduces CAPT-style labs which require students to identify a problem, ask questions, develop a hypothesis, design and conduct an experiment, analyze data, and draw conclusions. (YDS)

Presents a set of hands-on, outdoor science experiments designed to teach elementary school students about animal adaptation. The experiments focus on: how color camouflage affects an insect population; how spiderlings find a home; and how chameleons camouflage themselves by changing color. (SM)

Presents a laboratory exercise on the capabilities of plants to ward off the insects that want to eat them. (ASK)

Explores the use of quantitative EEG in the detection of lies employing a special electrode cap and specialized video recording and audio equipment. The method offers the ability to decide when it can predict accurately and when it can predict with 100% accuracy. (JPS)

Discusses the advantages of an extended school year and block scheduling for science learning. (DDR)

Describes an early childhood educator's approach to teaching children about rain, rainbows, clouds, precipitation, the sun, air, and wind. Recommends ways to organize study topics and describes experiments that can help children better understand the different elements of weather. (MOK)

Presents a science experiment in which students test the buffering capacity of household products such as shampoo, hand lotion, fizzies candy, and cola. Lists the standards addressed in this experiment and gives an example of a student lab write-up. (YDS)

Outlines how a course in robotics can be taught at the undergraduate level with specific experiments that can be used for incremental learning in programming a mobile robot or by simulating the actions of a robot. Contains 14 references. (Author/ASK)

Describes a variation of typical introductory chemistry stoichiometry experiments in which the reaction is run in a modified 20-ounce plastic soda bottle. (WRM)

Describes a simple time-of-flight experiment using readily available equipment. The method of measuring the speed of light uses a modulated laser and introduces students to some concepts of optics, measurement of very small time intervals, modulation of lasers, waveform generation, fast detectors, and data processing. (Contains 20 references.)…

Describes modifications to an apparatus for measuring the force of an object in circular motion. Explains how to accurately measure rotation rate with the use of a motion detector. (WRM)

Reports on a technique for illustrating the dependence of the rate of reaction on the concentration of the reactants and for determining the order of reaction with respect to each reactant, the overall order of reaction, the reaction rate constant, and the half-life. (WRM)

Discusses the history of the development of Newton's Law of Cooling. Describes an experiment conducted in the kitchen that is designed to test the rate of cooling of a hot block of iron. Finds that Newton's law does not represent very well the mechanism of heat loss. (Contains over 10 references.) (WRM)

Uses charcoal briquettes, ammonia, water, table salt, and laundry bluing to create white fluffy crystals. Briquettes are placed in a bowl while the remaining ingredients are mixed together and poured over the briquettes. The result is white fluffy crystals forming on top of the charcoal. This experiment dramatizes chemical reactions to…

Although reports of academic cheating are abundant, there are relatively few papers in the literature that focus on cheating in the context of science courses and even fewer that address dishonest practices, such as "cooking" or fudging data, within the classroom laboratory. This paper briefly reviews the existing literature on academic dishonesty…
