Lesson focuses on the engineering behind building a spring scale and its use as a measuring device. Students work in teams to design, build, and test their own spring scale that can measure the weight of an apple using everyday items. They compare their designs with those of other student teams and reflect on the experience.
This lesson focuses on how the sun’s energy can be used to heat and cool buildings. Teams of students construct passive solar houses from everyday materials. They then test their solar houses to determine how well they regulate temperature.
Lesson focuses on how packaging engineers develop customized shipping and packaging containers to meet the needs of many different industries. Students learn about different packages that have been engineered to transport hearts for surgery, blood for analysis, and foods to retain freshness. Students then work in teams to build a container that will allow a flower to be shipped without damage and with water using everyday items. Flowers must remain fresh and not wilted for 24 hours after being sealed in the box.
Lesson focuses on how structural engineers have improved the designs of building -- specifically roofing -- over the years to improve the quality of homes and life. Teams of students work together using simple materials to design a roof that will keep the contents of a box dry during a water test. Students determine both the shape of the roof and materials used for construction, test their designs, and present their findings to the class.
This lesson focuses on the tools and equipment used during technical rescue operations. Teams of students construct rescue devices from everyday materials. They then test their devices to determine whether they can rescue a puppy from a sewer.
This lesson focuses on devices that are used to detect air pollution. Teams of students construct outdoor air pollution detectors from everyday materials. They then test their devices to see how much particulate pollutants they can capture.
Lesson focuses on how engineers and others have developed and improved the manufacturing of recycled paper. Students work in teams to recycle and manufacture their own recycled paper while learning how recycled paper is manufactured on a larger scale in paper facilities. Student teams evaluate current processes for creating paper and develop improvement to the procedure.
Lesson focuses on the engineering behind keeping food and other items cool. Students work in teams to develop a system to make an insulated liquid container that will keep chilled water as cool as possible for an hour using everyday items. Students will need to devise a way to have a thermometer rest in the water and be able to read the temperature throughout the hour. They plan their design, execute and test their system and share their experiences with the class.
Lesson focuses on the different uses of dams and how they are engineered. Students work in teams to develop a system of damming water in a trough. The system must completely hold back the water and also have a way of executing a controlled release.
Lesson focuses on the engineering behind building framing for structures, and explores examples of geodesic domes and other buildings. Students work in teams to design and build a small dome frame out of everyday items that can hold a weight on top without collapsing.
