On your marks, get set, race! The 4-Wheelin’ project covers nine physical science concepts, such as friction, turning radius, force and much more. You’ll learn about each concept by conducting activities and experiments using a radio-controlled pickup. That pickup you thought was only a toy can also be used to learn how machines and energy do work that makes our lives easier. You’ll be asked to think about what happened, what you learned and how you can use what you’ve learned in other situations.
