Young children, especially boys, it seems, love to play with cars, trucks, boats, and airplanes. If you’ve ever watched a seven- to ten-year-old child operating a remote radio-controlled car (also called an RC car), you probably noticed that sooner or later a group has gathered, much to the child’s delight, to watch the fancy vehicle maneuvers that he orchestrates through a hand-held controller. Some middle school and high school science teachers have used RC cars as tools for teaching radio-control robotics and programming. Encourage your children to express their interests and develop them into hobbies. You’ll enjoy helping them while they are young, and you’ll be even happier if, as young adults, they decide to pursue meaningful careers in academic disciplines such as science.
