I HAVE A QUESTION: 72 Fabulously Fun Experiments You Can Do at Home to Learn the Science of the World Around Us - Tapa blanda

Reseña del editor

Heat is a form of energy. From a gentle breeze to a powerful explosion, it makes things move, and it travels from place to place. Water--a precious resource--exists as solid, liquid, and gas. It moves continuously through the water cycle, evaporating into the air from the oceans, condensing into clouds, and returning to earth through precipitation. Air--although invisible, it is real and all around us. Air pressure helps us breathe and to lift an airplane. Light is energy that travels from the sun. Because there is light we can see; and plants, which are at the bottom of the food chain, can live and grow. Sound is also a form of energy. It allows us to produce and have music, communicate with each other, and measure the depth of oceans.
