When monkeys fly: Making the periodic table fun for middle schoolers

Fruit Fly Family Fun

A recent comparative analysis of the sequenced genomes of 12 Drosophila species (Drosophila 12 Genomes Consortium, 2007; Stark et al., 2007) reveals a comprehensive picture of the evolution of small animal genomes and greatly improves computational predictions of functional elements in the D. melanogaster reference sequence.

The Periodic Electronegativity Table

The origins and development of the electronegativity concept as an empirical construct are briefly examined, emphasizing the confusion that exists over the appropriate units in which to express this quantity. It is shown how to relate the most reliable of the empirical scales to the theoretical definition of electronegativity in terms of the quantum potential and ionization radius of the atomic...

Making Mathematics Fun , Accessible , and

The theme of this year's conference is “Making Mathematics Fun, Accessible and Challenging through Technology”. Version 6 of Mathematica, released in May 2007, is instantly interactive, allowing teachers and students to easily construct live interfaces to illustrate and investigate mathematical concepts at all levels [1]. Over 2000 examples of these interactive capabilities, including a number ...

Making Chemistry Fun to Learn.

The major challenge that confronts undergraduate chemical education in US is the gap between the high demands that learning requires and the low efforts that students make partially due to the lack of motivation. This paper reports strategies to ameliorate student learning in the following areas: application of friendly presentation, utilization of analogies and correlation with everyday life. ...
