Here's the Challenge:

Apply knowledge of Newton's law of motion, momentum, and energy to design and construct a vehicle that will go as far as possible using an unbalanced force to create motion

Rules:

• Construct a vehicle that can travel at least 3 tiles (each tile is 60 cm). Vehicle must stay within a 2-tile wide path
• No forward force may be applied to vehicle by the student (me)
• Vehicle must be made of recycled/reused products. No pre-made vehicle parts
• Vehicle must travel using an unbalanced force to create motion 
• Students are not allowed to help vehicle along the path 
• Students may not use electricity/ fuel cells or manufactured containers of pressurized gas. This is a land vehicle. All vehicles start from a level surface ( no ramps or strings). All parts of vehicle must remain on vehicle, except fuel

     *Extra Credit- Vehicle travels 5 tiles
