Sandcastle Investigations

sandcastle investigationsIn this NGSS-aligned activity, 2nd graders draw on their knowledge of Earth science to follow the engineering design process and investigate solutions for protecting sandcastles from wind and water damage. They make hypotheses, measure and record changes, and support their results using evidence. Suitable for students in grades 1-3.

Shapes of Strength

house of cards with coins on topStudents 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.

Beat the Motion Sensor

light sensor nano circuitryIn 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.

Lesson: Concrete for Kids

concrete1Concrete 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.
