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.

This video segment adapted from NOVA shows how scientists use the fossil record to trace when early human ancestors and related species began walking on two legs instead of four, and to determine whether they were more apelike or human in appearance.

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.

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.

In this video excerpt from NOVA, find out how the discovery of a gene defect has led to the development of a new drug to treat patients with cystic fibrosis.

This video segment describes the basics of the circulatory system: how the heart pumps the blood that carries oxygen and nutrients throughout the body.

This course covers fundamentals of thermodynamics, chemistry, and transport applied to energy systems. Topics include analysis of energy conversion and storage in thermal, mechanical, chemical, and electrochemical processes in power and transportation systems, with emphasis on efficiency, performance, and environmental impact. Applications include fuel reforming and alternative fuels, hydrogen, fuel cells and batteries, combustion, catalysis, combined and hybrid power cycles using fossil, nuclear and renewable resources.

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.

This video from NASA describes the GLAST satellite, which is equipped with a gamma-ray telescope, and shares some background about the kinds of extreme universal phenomena indicated by the presence of gamma rays.

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.

"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."

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.

In this animation produced by WGBH and Digizyme, Inc., see how bacterial plasmids are engineered to clone or express genes that code for proteins such as human insulin.

In this video profile adapted from NOVA scienceNOW, learn about geneticist and rock musician Pardis Sabeti, whose innovative insights into natural selection demonstrated how beneficial mutations spread quickly through a population.
