Lesson: Bits & Binary
Posted on December 4th, 2011 by Mary Lord
In this activity, students in grades 4 – 12 will do math like a computer. They will learn the basics of binary number systems by writing and then counting on their hands, and use their knowledge to decode numbers and letters.

In this activity, teams of students in grades 3-12 explore the engineering design process by building model canoes from everyday materials and testing their design in a basin. The canoes must be able to float for three minutes and, for older students, support a load. Students then evaluate the effectiveness of their canoes and those of other teams, and present their findings to the class.
In this hands-on activity designed to teach chemical-engineering principles to freshman engineering students at Rowan University, teams of high school students will melt chocolate and coat commercially available cookies, then perform several measurements and calculations. They then will write a lab report that includes nutritional labeling and recommendations for improving the chocolate-coating process.
In this lesson, K-12 student teams have a limited period of time (18 minutes) to build the tallest free-standing spaghetti structure that can support a marshmallow. They learn how engineers collaborate to design, test, and improve on their ideas, as well as examine hidden assumptions that can derail the creative process and final product.
In this lesson, students in grades 6-8 discover how engineers can use biomimicry to enhance their designs. They learn how careful observation of nature — in this case, reverse engineering a flower — can lead to new innovations and products. 
NASA’s Gravity Recovery and Interior Laboratory (GRAIL) mission will launch twin spacecraft in tandem orbits around the Moon to measure its gravity in unprecedented detail and create a gravitational map. GRAIL MoonKAM will allow classrooms to request pictures of the lunar surface from cameras on the twin satellites. 
Concrete for Kids is a fun, hands-on activity to introduce students to engineering and concrete as an engineered material that engineers use to make the structures we use every day, including bridges, buildings, and roads. In this two-period lesson, teams of students in grades K-12 mix and pour concrete to form beams which, once hardened, are tested to see how much weight they can hold before breaking. 
Want to incorporate engineering into your STEM curriculum but don’t know where to start? Stephanie Greer, a technology integration specialist in an inner-city Philadelphia school, faced that exact challenge last year. She shares her top tips for making the most of eGFI, which she calls her “go-to site” for inspired engineering lessons, activities, and more!
You don’t have to be an engineer to introduce engineering concepts and design into your classroom. The eGFI site includes scores of inexpensive, engaging lessons – searchable by grade level or subject – that cover the various engineering disciplines. To kick off the school year and acquaint you with eGFI, we’ve assembled a dozen of 2011’s most popular lessons and activities. Have fun putting some “E” in your STEM classes this semester!
