Your readers have decided to compete in a science fair. They want to do a great project, but they have no ideas. Where should they start? With this unique and fun set of experiments, author Robert Gardner will show readers how to learn about physics with the help of their bicycle. How do the gears on a bike work? Why do some bikes need thicker tires than others? How can they use water balloons to measure a bike's speed? Readers will be surprised how many answers they can find with just a bicycle and a few other household objects. Terrific ideas for further experimentation are provided so that they can create original science fair projects.
