Lesson explores computer programming and the impact of computers on society. Students build and test a program to turn a light on and off using an Arduino board. They connect the hardware, program the code, test their system, adapt it for variations in blinking times, evaluate their results, and share observations with their class.
Lesson focuses on how the process of folding has impacts on engineering and is evident in nature. Students consider many applications of folding such as parachutes, wings in a cocoon, heart stents, and solar panels in space. They work in teams to create a model out of everyday items of a solar panel that can be folded (for transport) and expanded (in space). Students design their solar panel on paper, build it for transport, and open or test it. All teams evaluate their results, reflect on their design, and present to the class.
Lesson focuses on two simple activities younger students can do to gain an appreciation of nanotechnology. First, students measure their hands in nanometers, second students learn about liquid crystals, their applications and nanotechnology connections and test how the heat of their hands changes the color of the crystals. They observe what they see, present their findings to the class, and reflect on the experience.
Lesson focuses on graphene and its electrical properties and applications. Students learn about nanotechnology and how engineers can harness the differences in how materials behave when small to address challenges in many industries. Students work in teams to hypothesize and then test whether graphene is an electrical conductor or insulator. They build a simple circuit using everyday items, and create a graphene sample using soft pencils on paper. They observe what they see, extrapolate to broader applications, present their ideas to the class, and reflect on the experience.
Lesson focuses on how engineers have developed and use special tools that can observe the landscape of materials when they are working at the nano scale. Students learn about Scanning Probe Microscopes (SPM) and then work in teams using a pencil to explore and identify the shape of objects they cannot see, just as the SPM does at the nano level. They draw what their mind "sees" on paper, compare their results with other student teams, and share observations with their class.
Lesson focuses on how engineers have developed and improved traffic management over time by engineering and re-engineering the traffic light. Students work in teams to design a new traffic light system to meet the needs of a potential client. They must devise a system or technical enhancement to accommodate a busy bicycle lane and roadway that intersects a hospital emergency room entrance. As a team they devise their planned improvements, draw a design of the improved traffic signal, develop a written and verbal presentation to the client, present their designs to the class, provide feedback on other team's designs, and share observations about re-engineering.
Students will design, build, and characterize one of the basic circuits of electrical engineering, the voltage divider. These circuits produce a wide range of output voltages and are building blocks for more complex circuits. Circuit design will emphasize the concepts of Ohm’s Law and students will explore mathematical relationships of parallel and series resistors. Students will demonstrate their design efforts by building prototype circuits and using test measurement tools to confirm their predictions.
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.
Lesson focuses on how engineers improve assistive devices such as a cane to meet the needs of the elderly. Students work in teams to re-engineer a cane for a "client." They are assigned a client profile, develop a design to suit the needs of the user, and those in older grades build a working prototype of their design.
Lesson focuses on surface area and how the shape of sugar crystals may differ as they are grown from sugars of different grades of coarseness. Students explore surface area, nanostructures, and work in teams and participate in hands-on activities.
