rocket-launch

We have lift-off! And sometimes we donโ€™t…at first. Recently Ms. Beckโ€™s two sciences classes of 6th graders (one of which is shown here)  took their experiments in chemistry and engineering outdoors as part of a project integrating concepts studied throughout the school year. โ€œWe started the year with chemical equations,โ€ Ms. Beck explained, โ€œand vinegar + baking soda is a classic chemical equation. We ended the year with physics! We covered a wide range of forces, including the force of friction, aerodynamics, and Newton's laws. โ€œStudents were challenged to make a self launching, self-stabilizing rocket. Baking soda and vinegar were provided by me, but they could have used any nonflammable โ€˜fuel.โ€™ We had design days where their design needed to be researched and approved, build days, a test launch day to tinker with the design and vinegar to baking soda ratio, and then our final launch day a week later! โ€œIf students were able to design a rocket that overcame gravity, they got a 100%. Students helped each other, gave advice, and tried/re-tried different methods. It was a true experiment in the scientific method. I admit it was very rewarding to see all the rockets launched after days of student-led design, experimentation, research, and problem solving. โ€œOverall, it took 45 2L bottles, 37 Corks, 13.5 pounds of baking soda, and 12 gallons of vinegar!โ€ Having more materials meant students could try again, and they did. Too much vinegar? Not enough mixing? No lift-off? No problem. Reset and do over, just like real scientists. Great job, everyone, and thank you Ms. Beck!
