Come learn to contra dance! Contra is a type of traditional social dancing that’s high energy and a lot of fun. It’s done as couples in a long line, so you end up dancing with everyone else in your set. We’ll be starting from the very beginning, so no experience is needed, but come ready to dance; wear comfortable shoes and clothing and bring a water bottle if you can. We’ll teach how contra works and go over some basic moves, then spend the rest of the time dancing.

In 1948, smog descended on Donora, Pennsylvania. In less than three days, twenty people died and over a third of the town was sick; mortality rates were significantly higher than surrounding towns for many years. Smogs like this don't happen in the US anymore, because back when Congress was functional it passed this wonderful thing called the Clean Air Act. The CAA regulates airborne pollutants from asthma-causing O$_3$ and PM to acid-rain-forming SO$_2$. This class will cover a little bit of atmospheric chemistry, a little bit of history, and a little bit of regulatory and legal history, all focused around the CAA.

Earth science: where chemistry, physics, and biology meet to teach us awesome things about the world around us. Come learn about nitrogen, carbon, ozone, and sulfates, where they are in the earth system and how they get from one place to another. In the process, we'll talk about how human activity changes the earth, atmosphere, and oceans around us.

Do you like to sing, dance, paint or write? Do you want to learn more about all of these artistic fields? "The Arts" will feature a different teacher each week, addressing a different artistic idea. Some weeks, teachers will lecture, and teach students about things like the history of jazz or film theory. Other weeks, teachers will lead students in art projects, performing activities, or music sampling. Exact class topics for this summer are still to be determined. Each class will be taught by a different teacher, so it will be more like a series of seminars on the arts rather than an actual class on a specific topic.

Do you think you might want to be an engineer, but don’t know much about what an engineer does? This class is designed to expose you to problems in various engineering fields. Past classes have included model rocket design, taught by an aerospace engineer and sorting algorithms taught by a software engineer. The following engineering disciplines will be addressed (subject to change). Mechanical Engineering Civil Engineering Software Engineering Chemical Engineering Electrical Engineering Each class will be taught by a different teacher, so it will be more like a series of seminars on engineering than an actual class.

During the third block, middle school students are given the opportunity to participate in ESPrinkler, a mini-program that consists of about five one-shot (Splash-style) classes and activities each week. This summer's offerings are still largely undetermined, though some confirmed classes are "It's a Bird...It's a Plane...It's Bacteria?," "Your classical intuition is wrong," and "Storytime with Josh." While you don’t have to individually register for each activity, you must register for this course (ESPrinkler) to partake in the different activities offered every week!

Come hang out with other students and ESP volunteers. Eat snacks, relax, and chat about life, the universe, and everything!
