Aluminum Foil Boat Design: Surviving the Stormy Seas: experiment with aluminum foil boats to see how weight relates to a boat's ability to stay upright in turbulent water.The challenge is to launch the ball the greatest distance with accuracy (into the receiver). Ball Launcher Challenge: design a device that can launch a ball and another one that can catch the ball.The challenge is to design a machine that can successfully separate different kinds of materials. Build a Recycling-Sorting Machine: use magnetism as one approach to tackling a real-world problem of separating various materials that get combined in single-stream recycling programs.The challenge is to come up with a design for the fastest robot. Building Junkbots-Robots from Recycled Materials: use recycled and craft materials to design the bodies and appendages of simple robots.The challenge is to create a design that can launch a plane the farthest distance. Design a Paper Airplane Launcher: use principles of kinetic and potential energy to design and build a paper airplane launcher.The challenge is to design a bumper to protect a toy car from a crash. Engineering Car Crash Safety with Newton's Third Law: learn about Newton's third law of motion and the role of equal and opposite reaction forces in a car bumper system.The challenge is to successfully add loops to the design. Paper Roller Coasters: Kinetic and Potential Energy: build roller coasters from simple paper materials to experiment with potential and kinetic energy.The challenge is to improve the design to make the car travel as far as possible. Balloon Car Lesson Plan: explore kinetic and potential energy by designing and racing balloon-powered cars.The challenge is in using common materials to improve the design of the house to make it more stable during an earthquake. Students can test their buildings with a simulated earthquake and Google's Science Journal app. Build an Earthquake-Resistant House: learn more about structural engineering and build model earthquake-resistant buildings.The physics is there, but the engineering challenge involves building and iterating a solution. Teaching Engineering Design with an Egg Drop: learn about Newton's laws of motion and potential and kinetic energy while designing and testing a device to protect an egg from breaking when dropped from a certain height.Most of these design challenges use simple materials (like paper and recycled cardboard), which makes them good choices during school closures. As part of the process of designing, testing, and iterating, design challenges enable and encourage students to practice problem solving and troubleshooting, too. Students doing engineering design challenges have the opportunity to create and innovate as they work on projects that often have real-world significance or context. With a "build it" theme running throughout, design challenges like the ones listed below encourage students to use the engineering design process to brainstorm, design, prototype, test, and then make changes to continue a cycle of improvement and iteration.
Remote learning doesn't have to mean kids miss out on all of the fun, hands-on instruction they would have gotten in the classroom! Engineering design challenges are a great way to spark interest in STEM with students at home. Engineering Challenges are Great for Home or the Classroom!
