3-D Microbatteries
A collaboration between three universities is working to create a battery that is capable of powering microelectromechanical systems (MEMS). The work is especially important because no viable battery currently exists for these tiny devices. The three-dimensional battery will be a departure from current battery designs, which stack "positive and negative electrodes... like sheets of paper." As more electrodes are stacked to make a higher capacity battery, the size and weight increases dramaticall

Tutorial on Optimization Theory and Difference and Differential Equations
This online tutorial is intended for college students taking an early course in mathematical optimization or linear differential equations. Although it is written by a professor of economics, little economic theory is presented. This keeps the material centered on the mathematical aspects of optimization and differential equations, which have a wide range of scientific applications. The text is very well organized and is accompanied by illustrative figures. No prerequisites to the tutorial are l

Stormy Skies
Students learn that wind and storms can form at the boundaries of interacting high and low pressure air masses. They learn the distinguishing features of the four main types of weather fronts (warm fronts, cold fronts, stationary fronts and occluded fronts) and how these fronts are depicted on a surface weather analysis, or weather map. Students also learn several different ways that engineers help with storm prediction, analysis and protection.

Power to the People
Students read and evaluate descriptions of how people live “off the grid” using solar power and come to understand better the degree to which that lifestyle is or is not truly independent of technological, economic and cultural infrastructure and resources. In the process, students develop a deeper appreciation of the meaning of “community” and the need for human connection. This activity is geared towards fifth-grade and older students and Internet research capabilities are required. Po

Designing a Thermostat
Students investigate circuits and their components by building a basic thermostat. They learn why key parts are necessary for the circuit to function, and alter the circuit to optimize the thermostat temperature range. They also gain an awareness of how electrical engineers design circuits for the countless electronic products in our world.

Does Weight Matter?
Using the same method for measuring friction that was used in the previous lesson (Discovering Friction), students design and conduct an experiment to determine if weight added incrementally to an object affects the amount of friction encountered when it slides across a flat surface. After graphing the data from their experiments, students can calculate the coefficients of friction between the object and the surface it moved upon, for both static and kinetic friction.

What Do Bread and Beer Have in Common?
Students are presented with information that will allow them to recognize that yeasts are unicellular organisms that are useful to humans. In fact, their usefulness is derived from the contrast between the way yeast cells and human cells respire. Specifically, while animal cells derive energy from the combination of oxygen and glucose and produce water and carbon dioxide as by-products, yeasts respire without oxygen. Instead, yeasts break glucose down and produce alcohol and carbon dioxide as th

Seismic Waves: How Earthquakes Move the Earth
Students learn about the types of seismic waves produced by earthquakes and how they move the Earth. The dangers of earthquakes are presented as well as the necessity for engineers to design structures for earthquake-prone areas that are able to withstand the forces of seismic waves. Students learn how engineers build shake tables that simulate the ground motions of the Earth caused by seismic waves in order to test the seismic performance of buildings.
