![]() ![]() Heavier, more massive objects have more inertia and require more energy to start moving.In other words, it’s how much energy is required to move an object. Inertia is the tendency for an object to resist change in motion. The car takes time to reach maximum speed because of inertia.However, if you want to specialize the car for either speed or distance, then read on: The basic car design works well and it can still teach students about momentum, energy transformation, and inertia. You can find the lesson plan, 1-page project sheet, and more project ideas at This project is recommended for grades 4 and up, however smaller groups of younger students may build this car with extra help. Read on after the final project step to learn how to alter the design of the car to achieve each type of goal, and to see the accompanying teaching materials. With this, you can design the car to speedily sprint a short distance, or travel a long distance. ![]() One of the keys to a successful rubber band car are large wheels with rubbery grip that don't slip on the axel. Rubber bands are a convenient and effective way to teach energy transformation, and this rubber band car makes that lesson a blast!Ī quick Google search for " rubber band car project" yields tens of thousands of results, so why reinvent the rubber band-powered wheel? The top results show cars with small wheels without traction, or CD wheels which are difficult to attach to an axel, both of which aren't ideal for project-based learning. ![]()
