Students in grades 3 to 5 use engineering problem solving to create structures from paper, straws, tape, and paper clips that can support the weight of at least one textbook. For the second trial, they examine examples of successful buildings in history and try again.
Paris of students in grades 3 to 6 experience the engineering design process by building and modifying devices to catch and protect a “naked” egg as it is dropped from increasing heights. The activity scales up to district or regional egg drop competitions.
High school students working in teams of four learn how a device made with dye from berries can be used to convert light energy into electrical energy by building their own organic solar cells and measuring performance based on power output.

In this activity, students in grades 7 to 9 explore material properties as they relate to motion detection, and use that knowledge to make design decisions about what types of motion detectors to use in specific applications, such as conserving energy in commercial buildings.

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.
