Skimmer
Students construct paper sailboats and test the effect of different sail shapes, sizes, and construction methods to meet specific performance criteria. Friction, forces, the effect of surface area and design are some of the physical phenomena students encounter in this challenge.
JetToy
Students make balloon-powered toy cars that meet specific performance criteria like; travels far, carries weight, or goes fast. Jet propulsion, friction, air resistance and design are the core scientific concepts students explore in this challenge.
Gravity Cruiser
Student teams design and construct a vehicle that is powered by gravity. A weighted lever connected to an axle by string rotates on its fulcrum; as the weight descends it causes the axle attached to the string to rotate, propelling the cruiser forward. Concepts explored include potential and kinetic energy, friction, inertia, momentum, diameter, circumference, measurement, graphing, and constructing a prototype.
Electricity & Electronics
The Electricity & Electronics - Elementary activities provide teachers with activities that focus on principles of electronics by providing teachers with hands-on experiments involving static electricity, batteries and capacitors.
