Students imagine they are stranded on an island and must create the brightest light possible with the meager supplies they have on hand in order to gain the attention of a rescue airplane. In small groups, students create circuits using items in their "survival kits" to create maximum voltage, measu...

Students work within constraints to construct model trusses and then test them to failure as a way to evaluate the relative strength of different truss configurations and construction styles. Within each group, each student builds two exact copies of the team's truss configuration using his/her own ...

Students are challenged to find a way to get school t-shirts up into the stands during sporting events. They work with a real client (if possible, such as a cheerleading squad, booster club or band) to determine the requirements and constraints that would make the project a success, including a budg...

Biomedical engineers design, create, and test health technology that measure all sorts of physical functions in the body, including heartbeat. Students play the role of biomedical engineers in this activity and create a device that helps visualize heartbeats.

Students use a variety of common office and household supplies to design a boat. Their goal: to not only design the fastest boat, but also take into account how much mass or “cargo” the boat can carry, the stability of the boat in the water, the total mass of the boat, boat aesthetics, and how much ...

Students are challenged to design and build wind chimes using their knowledge of physics and sound waves, and under given constraints such as weight, cost and number of musical notes it must generate.

Students learn how to send signals (such as from buttons or sensors) from one system to another using XBee radio communication modules. By activity end, they are able to control LEDs and motors wirelessly using Arduino microcontrollers and XBee shields. Introduces the concept of the Internet of thin...
