Do as the Romans: Construct an Aqueduct!
In this activity, students work with specified materials to create aqueduct components that will transport 2 liters of water across a short distance in their classroom. The goal is to build an aqueduct that will supply Aqueductis, a Roman city, with clean water for private homes, public baths, and glorious fountains.
Climate Change Graphics from the Hall of Planet Earth
This collection of Climate Change Graphics is from Earth: Inside and Out, part of the Museum's Seminars on Science series. These distance-learning courses are designed to help educators meet the new national science standards.

The following activities will help you explore how the earth and moon move around the sun.
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.
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
Switchgrass Science - Partners Video Magazine
At the University of Tennessee, switchgrass is all the buzz - a plant that's farmer and environment-friendly, and a cheap alternative to high-priced corn for making ethanol.

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
The lessons in Geography 484 cover creation and editing of vector data layers; georeferencing image files; principles of relational database design; acquiring data via the Internet; managing the coordinate systems of datasets; metadata creation and editing; attribute and spatial joins, and thematic mapping for the sake of analysis; and much more. We give the people who feel they have the experience and skills covered in Geography 484 the option of testing out of the course by completing the fina
Urban Signatures: Sensible Heat Flux (WMS)
Big cities influence the environment around them. For example, urban areas are typically warmer than their surroundings. Cities are strikingly visible in computer models that simulate the Earths land surface. This visualization shows sensible heat flux predicted by the Land Information System (LIS) for a day in June 2001. Sensible heat flux is higher in the cities--that is, they transfer more heat to the atmosphere--because the surface there is warmer than in the surroundings. Only part of the g
Automotive Drum Brakes
Do you know when the first car was built? Do you know who built the first automobile? Would you guess, Henry Ford? Try again. Do you know by what means they used to stop that car? We know the brakes on the vehicles we drive today are quite different from those back in the 1800s. While knowing the history of the automobile is interesting, knowing how they work is also interesting. The automotive brake or to be more specific, the drum brake is what this instruction is designed to review. In this i
Spastic Paraplegia - Reflexes Exam - Abnormal (Pathological) Sub-exam - Patient 5
This video features a 54-year-old white male with a history of spastic paraplegia (diagnosed in 1994) and no previous history of heart disease or cardiac workup. He presented to the Emergency Room complaining of three days on-and-off retrosternal chest pain. Patient presented to the ER complaining of three days on-and-off retrosternal chest pain, rated 3/10, lasting approximately 30 minutes, occurring multiple times daily at rest or during activity. The first episode occurred three days before
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
