  20. Today’s Activity

  21. Today’s Activity CO2 Propelled Boat Objective Create a CO2 propelled boat that travels the greatest distance in the minimum amount of time.

  22. Materials Other Materials • Baking soda • Vinegar • Clear plastic tape • Pennies • Graduated cylinders • Exact-o Knifes

  23. Today’s Activity CO2 Propelled Boat Objective Create a CO2 propelled boat that travels the greatest distance in the minimum amount of time. Mechanical Motion Fuel Propulsion

  24. Today’s Activity CO2 Propelled Boat Objective Create a CO2 propelled boat that travels the greatest distance in the minimum amount of time. Baking Soda and Vinegar Mechanical Motion Fuel Propulsion

  25. The “Combustion” Process

  26. The “Combustion” Process

  27. The “Combustion” Process

  28. Design Considerations • Best ratio of baking soda to vinegar (How can you systematically optimize it?) • Method to seal the reaction chamber without mixing the baking soda and vinegar • Size/placement of exhaust hole(s) for CO2 to escape • Appropriate weight and its distribution
