This video segment from NOVA: "The Killer's Trail" investigates the potential for DNA evidence to solve murder cases, even those from the distant past.

In an earlier lesson, students learned about the steel making and forging process. In this lesson, students will create a die using a 3D printer and then forge a part using play-dough. The lesson culmination will be a trip to the local business “Walker Forge” located in Clintonville, WI.

What do hit records tell us about life and business in post-WWI Wisconsin?

After World War I, factories and mass production were booming—and so was the record business! People had income to buy records and record players, and companies took notice. Paramount Records, started by the Wisconsin Chair Company based in Port Washington, sold records by well-known musicians of the time until the Great Depression crashed the party.

This episode is part of The Look Back, a series made for learners in grades 4-6 that explores eras from Wisconsin’s history through artifacts. The collection is hosted by historians who model an inquiry process: sharing artifacts, asking questions, visiting archives and museums to learn more, telling the story of their findings as they go, and making connections to our lives today.

Learn how to make waves of all different shapes by adding up sines or cosines. Make waves in space and time and measure their wavelengths and periods. See how changing the amplitudes of different harmonics changes the waves. Compare different mathematical expressions for your waves.

" This class provides an introduction to quantitative models and qualitative frameworks for studying complex engineering systems. Also taught is the art of abstracting a complex system into a model for purposes of analysis and design while dealing with complexity, emergent behavior, stochasticity, non-linearities and the requirements of many stakeholders with divergent objectives. The successful completion of the class requires a semester-long class project that deals with critical contemporary issues which require an integrative, interdisciplinary approach using the above models and frameworks."

This interactive visualization created by FRED (Free Energy Data), displays energy supply (by source) and demand (by use) for each state in the US from 1960 to 2010; forecasts through 2035 are available as well. FRED is an open platform to help state and local governments, energy planners and policy-makers, private industry, and others to effectively visualize, analyze, and compare energy-use data to make better energy decisions and form sustainable strategies.

Frenchman Louis Daguerre's improvements in photography reached America in the 1840s. Personal portraits were soon the craze, and daguerreotype' studios sprang up in every city, while traveling daguerreotypists served the countryside. This picture presents the controlled environment of the early studios. It took so long to properly expose a photographic plate that the subject needed a head brace to hold a pose.

This animated slideshow introduces biodiesel as a fuel alternative. With concern about the use of petroleum-based fuels at an all-time high, biodiesel is experiencing a popularity surge. And algaeâotherwise known to some as pond scumâ are grabbing headlines as the next potential biodiesel superstar. But how and why do algae make oil? And why do they make so much of it? In this audio slide show, U.C. Berkeley's Kris Niyogi describes the process and its potential.

This fuel cell animation demonstrates how a fuel cell uses hydrogen to produce electricity, with only water and heat as byproducts. The animation consists of four parts - an introduction, fuel cell components, chemical process, and fuel cell stack.

This design-based subject provides a first course in energy and thermo-sciences with applications to sustainable energy-efficient architecture and building technology. No previous experience with subject matter is assumed. After taking this subject, students will understand introductory thermodynamics and heat transfer, know the leading order factors in building energy use, and have creatively employed their understanding of energy fundamentals and knowledge of building energy use in innovative building design projects. This year, the focus will be on design projects that will complement the new NSTAR/MIT campus efficiency program.

During a scavenger hunt and an art project, students learn how to use a handheld GPS receiver for personal navigation. Teachers can request assistance from the Institute of Navigation to find nearby members with experience in using GPS and in locating receivers to use.

Relatively few Americans directly experienced trench warfare and poison gas, innovations that rendered war newly terrible and fearsome. One such participant was William L. Langer, later a historian of the war, Harvard professor, and president of the American Historical Association. Langer served as an engineer in Company E of the 1st Gas Regiment, Chemical Warfare Service, of the U.S. Army. In this taut account, from Gas and Flame in World War I, he described a harrowing mission to move supplies and munitions near enemy lines, in preparation for a machine gun and gas attack. Langer noted that his story was probably the first published by an American unit after the war; four hundred copies were printed for the members of the 1st Gas Regiment.

The purpose of the course is to cultivate the sensibilities necessary for effective planning practice. This objective rests on one key assumption: that a set of key sensibilities creates the right mindset for practice.

"What can we learn about science and technology--and what can we do with that knowledge? Who are "we" in these questions?--whose knowledge and expertise gets made into public policy, new medicines, topics of cultural and political discourse, science education, and so on? How can expertise and lay knowledge about science and technology be reconciled in a democratic society? How can we make sense of the interactions of living and non-living, humans and non-humans, individual and collectivities in the production of scientific knowledge and technologies? The course takes these questions as entry points into an ever-growing body of work to which feminist, anti-racist, and other critical analysts and activists have made significant contributions. The course also takes these questions as an invitation to practice challenging the barriers of expertise, gender, race, class, and place that restrict wider access to and understanding of the production of scientific knowledge and technologies. In that spirit, students participate in an innovative, problem-based learning (PBL) approach that allows them to shape their own directions of inquiry and develop their skills as investigators and prospective teachers. At the same time the PBL cases engage students' critical faculties as they learn about existing analyses of gender, race, and the complexities of science and technology, guided by individualized bibliographies co-constructed with the instructors and by the projects of the other students. Students from all fields and levels of preparation are encouraged to join the course."

Build a gene network! The lac operon is a set of genes which are responsible for the metabolism of lactose in some bacterial cells. Explore the effects of mutations within the lac operon by adding or removing genes from the DNA.

The penetration of the railroads into the West in the late nineteenth century had a profound impact on local economies. For a period of ten years in the 1880s the Latah County, Idaho town of Genesee experienced this phenomenon. One town boomed while its neighbors languished in economic isolation, largely as a result of the rail station in Genesee. In this oral history interview, Kenneth Platt described the railroad's impact on Latah County.
