Anisotropic Oscillator Model
The EJS Anisotropic Oscillator model displays the dynamics of a mass connected to two opposing springs. The simulation displays the motion of the mass as well as the trajectory plot. The initial position of the mass can be changed by dragging. The unstretched lengths of the springs can changed as well via textboxes.

"Electromechanical Dynamics, Spring 2009"
" First published in 1968 by John Wiley and Sons, Inc., Electromechanical Dynamics discusses the interaction of electromagnetic fields with media in motion. The subject combines classical mechanics and electromagnetic theory and provides opportunities to develop physical intuition. The book uses examples that emphasize the connections between physical reality and analytical models. Types of electromechanical interactions covered include rotating machinery, plasma dynamics, the electromechanics o

Normalization of relations with Communist China
Following on from President Carter's December 15, 1978 announcement recognizing the People's Republic of China and the establishment of diplomatic relations, Evelyn Wong looks into the divided reaction of Boston's Chinese American community to United States-China normalization. Peter H.F. Wong, President of the New England Chinese Consolidated Benevolent Association, thinks the normalization of relations is entirely inappropriate.

The Power of Genetics: Using Classical and Molecular Genetics to Study "Real" Developmental Phenomen
The goal of this laboratory exercise is to provide a laboratory experience for undergraduates, in which they apply fundamental genetic principles to the study of a complex developmental process, specifically, root cell shape determination in the simple plant Arabidopsis thaliana. In this exercise, students identify putative root cell shape mutants, analyze an F2 segregating population, and finally use molecular techniques to determine where a specific mutation in located within the genome.

Use PCR and a Single Hair to Produce a "DNA Fingerprint"
As a former student once commented, "PCR is the sliced bread of molecular biology". Polymerase Chain Reaction (PCR) is a process that allows an investigator to amplify a portion of a single piece of DNA into over one billion copies. We have used PCR with our Introductory Biology students to generate a simple "DNA fingerprint". This exercise will outline all the steps required to generate a DNA fingerprint for each student during two lab meetings. This article covers the background information co

Using A Molecular Marker to Study Genetic Equilibrium in Drosophila melanogaster
Using Polymerase Chain Reaction (PCR), genetic variation in a laboratory population of Drosophila is characterized. The population contains flies with two variants of a molecular marker. DNA from individual flies is amplified by PCR, generating products which are either "long" or "short" when visualized on an agarose gel. Three PCR "genotypes" (long/long, long/short, and short/short) are distinguishable and should be present in Hardy-Weinberg frequencies. The exercise requires one session for gr

Refraction of Light Demonstration
In this interactive activity featuring videos adapted from the Rutgers PAER Group, observe the refraction of light as it passes through transparent objects. In the first example, when a convex lens is placed in the path of parallel beams of light, the beams converge after passing though the lens. In the second example, when a concave lens is placed in the path of parallel beams of light, the beams diverge after passing through the lens. In the third example, when a rectangular piece of glass is
