- Kitchen Chemistry: The Chemical Reaction Powered Car
The concepts involved in this activity are: Kitchen chemistry (baking soda and vinegar) for the chemical reaction; chemical reactions producing phase changes (gases, liquids, and solids); propulsion; and most importantly engineering design and re-design.
Kitchen Chemistry will power the Cars!
Vinegar + Baking Soda --> Water + Carbon dioxide gas + Sodium Acetate
The goal in this experiment will be to attempt different chemical ratios to produce enough gas to drive our cars approximately 25 feet.
While the exact details of this experiment are quite open, a general procedure is outlined below. Prior to building the cars, it is a good idea to develop an understanding for how much gas will be produced. Thus the procedure is broken into three sections: gas production, car construction, and car operation.
