Act III: Building the Car


In Act III, we present detailed step-by-step instructions on how to build a winning car -- using what we learned in the Physics section (Act II). We emphasize safety at all times, and give guidelines for maximizing your child’s involvement, while ensuring safety. You can print out a list of materials and tools needed for building the car, by placing the DVD in a computer. You can also print out a template for cutting out the basic shape of the car.
