- Abstract:
In some cities, especially large cities such as Los Angeles or Mexico City, visible air pollution is a major problem, both for human health and the environment. A variety of sources contribute to air pollution, but personal vehicles account for one of the main sources. Though each car has relatively low emissions when compared to vehicles of the 1970s, there are so many more cars on the road now that their emissions play a large role in overall pollution. In this activity, students think about alternate ways to power a vehicle to reduce emissions. Student teams design an eco-friendly car using the engineering design process, and make a presentation to showcase their product.

- Abstract:
Looking at transportation and the environment, students learn that some human-made creations, such as vehicles, can harm the environment. They also learn about alternative fuels and vehicles designed by engineers to minimize pollution. The associated hands-on activity gives students a chance to design their own eco-friendly vehicle.

- Abstract:
Students learn more about magnetism, and how magnetism and electricity are related in electromagnets. They learn the fundamentals about how simple electric motors and electromagnets work. Students also learn about hybrid gasoline-electric cars and their advantages over conventional gasoline-only-powered cars.

- Abstract:
" This course will explore a diverse collection of striking biological phenomena associated with the X chromosome. We will examine the genetic basis and significance of several X-linked mutations. We will also discuss why men are more likely than women to display X-linked traits. We will look at the different mechanisms by which X chromosome gene expression is equalized in mammals, flies, and worms and how these mechanisms can yield unusual phenotypes. Throughout our discussions of the X chromosome we will use both recent and classic primary research papers to learn about this chromosome's fascinating biology. This course is one of many Advanced Undergraduate Seminars offered by the Biology Department at MIT. These seminars are tailored for students with an interest in using primary research literature to discuss and learn about current biological research in a highly interactive setting. Many instructors of the Advanced Undergraduate Seminars are postdoctoral scientists with a strong interest in teaching."
