Solar Sails: The Future of Space Travel

LightSail solar sail spacecraftTeams of students in grades 7 to 9 follow the engineering design process to create, construct, test, and improve model solar sails made of aluminum foil to move cardboard tube satellites through “space” on a string. During the process, they learn about Newton’s laws of motion and the transfer of energy from wave energy to mechanical energy.

Build an Artificial Bicep

arm wrestling with musclesStudents in grades 5 to 7 learn about how muscles work and follow the engineering design process to create their own biomedical device to aid in the recovery of a strained bicep. They discover the importance of rest to muscle recovery and that muscles (just like engineers!) work together to achieve a common goal.

Saving a Life: Heart Valve Replacement

heart illustration with EKG chartStudents in grades 6-8 use their knowledge about how healthy heart valves function to design, construct, and implant prototype replacement mitral valves for hypothetical patients’ hearts. In the process, they discover the pros and cons of different types of artificial heart valves based on materials, surgery requirements, and lifespan.

Engineering Ethics: Evaluating Popular Inventions

US Customs and Border Protrection Verisign biometric scan at Dulles airport 2018High school students analyze an assortment of popular inventions to determine their intended beneficiaries as well as who has access to, might be harmed by, and is profiting from them. They then develop and apply class standards for ethical design to re-imagine the devices in a way that would do more good for humanity.

Toxic Island: Design Devices to Deliver Goods

Toxic Island design challenge Central Michigan UA classic engineering challenge involves designing and building devices that can deliver necessary goods to “Toxic Island,” an island that has been quarantined by the World Health Organization due to a nasty outbreak of disease. Working within specific constraints, including limited materials, middle school students follow the engineering design process to design, test, and improve a device that can deliver “medicine” and other vital supplies accurately and quickly without touching either the water or island.
