111 years ago airplanes had not even made their first flight, yet today we can fly to the other side of the world in 12 hours! It is thanks to advances in technology that we are able to explore so much of the world. Over the next five days teams will have to work together to see who is able to travel the farthest around the world. This trek around the world will require students to design their very own boat, plane, and even a rocket!
Bridge to the Open Road
In this activity, students will design a bridge to meet design specifications using limited materials, use basic drafting tools to create an effective bridge design, and analyze how different geometries support loads. They will calculate the strength to weight ratio and discuss how improvements to a design can increase the strength to weight ratio.
Cross Country Drag Race
Students will build a dragster in an attempt to understand some difficulties of building a dragster. They should analyze two different ways to propel a model car and learn how potential and kinetic energy relate to the motion of both a balloon- powered car and a dragster.
Crossing the Ocean
Students will build a canoe that allows them to explore basic mechanics of marine propulsion and design. They should conceptualize designs based on a given set of materials and other constraints, extend their knowledge of buoyancy and buoyant forces, build a simple electrical circuit to accomplish a specific task, and understand one example of the real-world effects of aerodynamics.
Students will design a neutrally buoyant blimp that can carry passengers and move with air currents, helping them to understand the forces of lift, thrust, gravity, and drag, and how they relate to aerodynamics. They will use the principles of buoyancy to investigate why some objects float and others do not.
Students will build bottle rockets, investigating the different components of their bottle rocket and the functionality of their real-world counterparts. They should understand how different propellants affect flight duration.
