Educause: Educating the Net Generation
Educause, a nonprofit organization "whose mission is to advance higher education by promoting the intelligent use of information technology," has made available this video file of a talk by their Vice President entitled "Educating the Net Generation" The online abstract describes the presentation as an exploration of "the implications of the Net Generation for colleges and universities as well as how to address the generation gap between faculty or administrators and the Net Gen." The presentati
Modeling & Simulation
Modeling & Simulation is a journal published by The Society for Modeling and Simulation International. The Society has made its 2004 Modeling and Simulation Resource Guide available free to download. The directory provides descriptions and contact information for the many modeling and simulation software packages currently available, as well as listings for various modeling and simulation organizations worldwide. Two guest articles describe techniques for the application of real-time simulation
Max Planck Institute for Gravitational Physics
This expansive Web site features the Max Planck Institute for Gravitational Physics' research dealing primarily with geometric analysis and gravitation, astrophysical relativity, quantum gravity and unified theories, and laser interferometry and gravitational wave astronomy. After learning about the Institute's origins in 1995, researchers can find out about the institute's intense efforts and hardships in developing a consistent theory of quantum gravity as well as its investigation in gravitat
An introduction to our solar system: the planets, our Sun and our Moon. Students begin by learning the history and engineering of space travel. They make simple rockets to acquire a basic understanding Newton’s third law of motion. They explore energy transfer concepts and use renewable solar energy for cooking. They see how engineers design tools, equipment and spacecraft to go where it is too far and too dangerous for humans. They explore the Earth’s water cycle, and gravity as applied to
Will It Fly?
In this lesson, students will learn about kites and gliders and how these models can help in understanding the concept of flight. Students will design and build their own balsa wood models and experiment with different control surfaces. The goal of this lesson is for students to apply their existing knowledge about the four forces affecting flight and apply engineering design to develop a sound glider. They will also communicate the reasoning and results of any design modifications made.
This lesson will allow students to explore an important role of environmental engineers: cleaning the environment. Students will learn details about the Exxon Valdez oil spill, which was one of the most publicized and studied environmental tragedies in history. In the accompanying activity, they will try many “engineered” strategies to clean up their own manufactured oil spill and learn the difficulties of dealing with oil released into our waters.
Six Minutes of Terror
This lesson discusses how each component of a spacecraft is specifically designed so that a rover can land safely in six minutes. Also, students will learn how common, everyday materials and technology, like nylon, polyester and airbags, are used in space-age technology.
Students learn a simple technique for quantifying the amount of photosynthesis that occurs in a given period of time, using a common water plant (Elodea). They can use this technique to compare the amounts of photosynthesis that occur under conditions of low and high light levels. Before they begin the experiment, however, students must come up with a well-worded hypothesis to be tested. After running the experiment, students pool their data to get a large sample size, determine the measures of
Pointing at Maximum Power for PV
Student teams measure voltage and current in order to determine the power output of a photovoltaic (PV) panel. They vary the resistance in a simple circuit connected to the panel to demonstrate the effects on voltage, current, and power output. After collecting data, they calculate power for each resistance setting, creating a graph of current vs. voltage, and indentifying the maximum power point.
Cars: Engineering for Efficiency
Students learn how the aerodynamics and rolling resistance of a car affect its energy efficiency through designing and constructing model cars out of simple materials. As the little cars are raced down a tilted track (powered by gravity) and propelled off a ramp, students come to understand the need to maximize the energy efficiency of their cars. The most energy-efficient cars roll down the track the fastest and the most aerodynamic cars jump the farthest. Students also work with variables and
The Need for Shelter
In this lesson, the students will build a shelter in order to protect themselves from the rain. After the shelters are built, the class will perform durability and water proof testing on the shelters.
Particle Sensing: The Coulter Counter
Students are presented with a short lesson on the Coulter principle — an electronic method to detect microscopic particles and determine their concentration in fluid. Depending on the focus of study, students can investigate the industrial and medical applications of particle detection, the physics of fluid flow and electric current through the apparatus, or the chemistry of the electrolytes used in the apparatus.
It’s all In the Package
In this activity, students explore the concept of “reducing” solid waste and how it relates to product packaging and engineering advancements in packaging materials. Students read about and evaluate the highly publicized packaging decisions of two major U.S. corporations. They will evaluate different ways to package items in order to minimize the environmental impact, while considering issues such as cost, availability, product attractiveness, etc. Students will explore “hydrapulping” an
Backyard Weather Station
Students use their senses to describe what the weather is doing and predict what it might do next. After gaining a basic understanding of weather patterns, students act as state park engineers and design/build “backyard weather stations” to gather data to make actual weather forecasts.

Edd Presnell: Dulcimer Maker
Edd Presnell, a mountain craftsman and native of Watauga County, North Carolina, demonstrates and comments on the construction of a dulcimer. Presnell learned his craft from his father-in-law. Film includes a brief performance on a finished dulcimer by his wife, Nettie. This 16mm film is archived in the Thomas G. Burton and Jack Schrader collection in the Archives of Appalachia, East Tennesse State University.

Quick take on Pythagoras and his theorem
A topic once reserved for high school geometry, the Pythagorean theorem is now part and parcel of the middle school curriculum. These resources offer visual demonstrations that can make the abstract theorem more concrete for students and lead them in analyzing the mathematical relationships involved, as recommended by the Principles and Standards for School Mathematics. The last resource offers background information on Pythagoras himself.
Lines of best fit using least squares
Fit a line to the data in a scatter plot using your own judgment. Then compare the least squares line of best fit.
Library 2.0: A Journey of Metamorphosis
Libraries as we know them have changed over the years to become Learning Commons—less like rooms with books and more like learning spaces with a wide variety of resources.
