FoilSim and CurveBall
FoilSim II computes the theoretical lift of a variety of airfoil shapes. The user can control the shape, size, and inclination of the airfoil and the atmospheric conditions in which the airfoil is flying. The program includes a stall model for the airfoil, a model of the Martian atmosphere, and the ability to specify a variety of fluids for lift comparisons. The program has graphical and numerical output, including an interactive probe which you can use to investigate the details of flow around

Kindler Syndrome described by Theresa Kindler in 1954 is probably a variant of hereditary acrokeratotic Poikiloderma in which Poikiloderma is preceded by a tendency to blistering following traumatic blisters. There are few ultrastructural studies on this syndrome. The ultrastructural level of blister formation has not been well characterized. Prof. Camillo O. DI CICCO, M.D.Presented to VIth Congress of the European Society for Pediatric Dermatology.
This tutorial on crystallography is broken down into equipment set-up, x-ray diffraction basics, symmetry and space groups, structure factors and phase problems, phasing techniques, model building, and real space correlation plots. Diagrams and interactive topics accompany the text, along with an interactive applet on Bragg's Law.
Sticks and Stones Game
Students will play Sticks and Stones, a game based on the Apache game "Throw Sticks," which was played at multi-nation celebrations. Students will collect data, investigate the likelihood of various moves, and use basic ideas of expected value to determine the average number of turns needed to win a game.
This site provides visual resources that illustrate the process of chemical weathering. Animations demonstrate how temperature and precipitation affect the evolution of parent material from highly resistant primary minerals to both secondary minerals and minerals in solution, as well as showing rates of weathering of various common minerals. A collection of photographs gives examples of chemical weathering in both natural outcrops and constructed features such as tombstones and carvings. These r
Teaching Mineralogy: A Digital Collection of Teaching Materials
This site from the "On the Cutting Edge" workshop series features a collection of resources for teaching mineralogy at the undergraduate level. These digital teaching materials are designed for faculty to use while designing new courses, enhancing existing courses, or simply looking for new ideas in teaching mineralogy. Students will also find this collection helpful for finding supplemental study materials and for doing research projects in mineralogy.
Solar System Animations
This site features Flash animations that illustrate phases of the moon, distances between planets, total, partial, and annular eclipses, and solar system formation that includes an example of the impact that created the moon. These resources are suitable for use in lectures, labs, or other teaching activities.
Martin Van Buren's "Return to the Soil"

You Decide: Is the Bush administration doing enough to protect the environment?
This educational guide focuses on environmental issues and the role of the Bush administration in safeguarding the energy requirements of the nation while at the same time protecting the environment from pollution and toxic emissions. Students are invited to examine the arguments on both sides of the debate, developing critical thinking skills as they work through the activities. Students will learn how to support their arguments with evidence and reason. It is expected that at the end of this g
What's Growing in That Dish?
In this lesson, students will view the clips of the video discussing the discovery of penicillin and the scientific discovery process. They will then run their own open-ended experiments to see how body molds and bacteria respond to variable substances.
