On a Saturday morning at the park, Emma and Noah race to the big oak tree—then Dad turns their fun into a physics lesson. With stopwatches, lake loops, and cyclists on the path, they discover how speed, velocity, distance, and displacement are different—and why direction matters.

On Outdoor Learning Day, Lila and Jay follow Ranger Maya’s treasure map through Green Valley Nature Park. Along rivers, hills, fields, and forests, they discover that Earth’s real treasures are natural resources—and learn which ones can renew and which ones we must use wisely.
Los átomos son los bloques de construcción más pequeños de la materia. Las moléculas se forman cuando los átomos se unen. Los compuestos son moléculas hechas de distintos tipos de átomos, como el agua (H₂O). La química nos ayuda a entender cómo estas piezas diminutas forman el mundo que vemos.
