This Web site, created to complement the Hall of Meteorites, looks at these fallen rocks and what they tell scientists about the formation of stars and planets.
The most ‘important and greatest puzzle’ we face as humans is ourselves (Boring, 1950, p. 56). Humans are a puzzle – one that is complex, subtle and multi-layered, and it gets even more complicated as we evolve over time and change in different contexts. When answering the question ‘What makes us who we are?’, psychologists put forward a range of explanations about why people feel, think and behave the way they do. Just when psychologists seem to understand one bit of ‘who we are’

The Struggle for Existence: Competition Between Bacterial Strains
Two strains of Escherichia coli are grown in broth and plated out at intervals. A population growth curve is plotted for each strain. The two strains are then grown together for several days in different types of broth. Students from each day's laboratory plate out the mixed culture on selective media. Data are pooled. Population curves are plotted for the two strains in competition. With different conditions, it is possible to observe competitive displacement of one strain by another.
Living and non-living things
Living things often rely on non-living things to accomplish daily tasks. Living things have several characteristics that non-living things do not, such as the ability to move, eat, breathe, and reproduce. Living things and non-living things can interact even though they do not have the same characteristics.
Urethral Catheters: A Historical Review
In the Graeco-Roman era and in the Middle Ages in Europe, S-shaped bronze catheters with one terminal eye were in common use. In the East, the evolution of urethral catheters started with the firm establishment of Muslim supremacy, and by 1013, straight or one-curve catheters made of gold, silver, copper, lead or salve of white lead with a rounded end and many side holes and a stylet were the standard instruments. Then in Europe in 1853 a prototype of the Foley catheter was designed. The next im

The Numbers Behind Hunger: Calorie Counting
Following are a series of activities in which students apply various math skills to better understand the problems of world hunger and what steps are being taken to reduce the number of people without enough to eat. This activity makes use of basic math skills to learn more about the energy value of food. A link to the US Dept. of Agriculture National Nutrient Database is listed here. Teachers may want to browse through the database first and determine the best way to present it to students: let
GIS Database Development

How Lou Got the Flu
This article from our family magazine series traces the spread of the flu virus from a duck in China to a young girl in Kansas. The article begins by introducing kids to Louise and the symptoms of influenza. On a series of clickable screens, they learn how the flu virus traveled from a duck to a pig to a farmer to a shopper to a student to Louise. A sidebar (But I Got a Flu Shot Last Year...) explains why influenza is trickier to outsmart than smallpox and polio. Another sidebar ("Microbes on th
