The Child's Book of Nature Air Light etc (en Inglés) - Worthington Hooker

Worthington Hooker invites children to notice the forces at play in ordinary life-air that presses, water that seeks level, heat that spreads, and light that fills the eye. With friendly steps and simple experiments, he explains wind, flying and swimming, pumps and barometers, clouds and snow, color and electricity, magnetism, gravitation, the earth's motion, and even friction-always choosing what a young learner can grasp and enjoy. Chapters build by natural gradation: one idea at a time, in the right order, from easy to more complex, with comparisons that make hard things plain. The result is natural philosophy that feels alive and intelligible, anchored in everyday objects from umbrellas to balloons.
