The best science gift is one a child can watch working. Stirling engines turn the heat of an alcohol lamp or hot water into motion, solar motors spin in sunlight, and magnetic levitation makes objects float, all without screens.
Younger kids do best with heat-powered or solar models; older kids can tackle a car engine kit with an adult. Fuel-powered engines are best left to grown-ups.
