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 game, teams of students in grades 3 – 8 are introduced to the economics and environmental constraints of mining by extracting “ore” (chocolate chips) from purchased “property” (cookies). They will learn that mining requires investment before resources can be extracted, and that there are costs associated with permits, environmental monitoring, and reclamation.
In this activity, students in grades 5 – 7 learn how motion capture technology (mo-cap) enables computer animators to create realistic effects. They learn the importance of center of gravity in animation and how to use the concept in writing an action scene. 
In this activity, students in grades 5 – 11 will use M&Ms to learn about radioactivity, the rate at which an isotope decays, and the concept of half-life. They will count and record the number of decayed “atoms” and graph the results.
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. 
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!
