Presents a demonstration that is a safe blend of two other vivid and memorable demonstrations. Combines two exothermic reactions involving granulated sugar to devise a reaction that produces a small amount of smoke and a growing column of black carbon. (DDR)

The practical epistemologies of university students during laboratory work in chemistry are analyzed to enhance understanding of how teaching practices interact with learners. The purpose is to develop a theoretical framework of learning as action that can be used by educational researchers to examine meaning-making, but also by teachers in close…

Studies of gene expression following fear conditioning have demonstrated that the inducible transcription factor, "egr-1," is increased in the lateral nucleus of the amygdala shortly following fear conditioning. These studies suggest that "egr-1" and its protein product Egr-1 in the amygdala are important for learning and memory of fear. To…

This pilot study obtained baseline information on verbal and visual rhetorics to teach microscopy techniques to college biology majors. We presented cell images to students in cell biology and biology writing classes and then asked them to identify textual, verbal, and visual cues that support microscopy learning. Survey responses suggest that…

Describes a procedure for teaching undergraduate instrumental analysis laboratories to help minimize student confusion about the instruments. Handouts are distributed prior to the experiments and a thorough discussion of the instruments is given at the beginning of the experiment, followed by a demonstration of the instrument by the instructor.…

Through a series of puzzles involving many geometric Objects,

Describes an undergraduate analytical chemistry course that utilizes instrument modules, which show how the key parts of an instrument fit together and contribute to the overall operation of the instrument. (MLH)

In the activity described here students build mazes, then time fellow students as they "run" the mazes. They then graph the results to determine a learning curve. (SD)

Describes an undergraduate chemistry laboratory course designed to acquaint the students with the major laboratory instruments, the chemical literature, and methods for writing effective laboratory reports. (MLH)

Describes the life cycle and control of the greenhouse whitefly. Explains the culture of the whitefly for school use and presents a list of laboratory exercises that can be done in a double period. (GS)

A course in Life Support Systems that has been adapted to increased class size is described. The curriculum includes lectures, seminars, laboratory demonstrations and operating room and intensive care rounds to introduce the student to life support concepts. (Author/PG)

The author describes a model for operations on the set of rationals. Thi s model, used by students in a laboratory situation, is based on an easily constructed number balance. (SD)

A pair of experiments, appropriate for the lower division fourth semester calculus or differential equations course, are presented. The second order differential equation representing the equation of motion of a simple pendulum is derived. The period of oscillation for a particular pendulum can be predicted from the solution to this equation. As a…

This reference guide contains laws, regulations, and licensing requirements and procedures governing chiropractic practice in New York State. Following a general introduction to professional regulation in New York State, licensure requirements are spelled out in detail, including general requirements, education requirements, examination…
