Plants grow through a fascinating process called photosynthesis, which allows them to make their own food. In this process, plants absorb sunlight through their leaves, using a green pigment called chlorophyll. The plant then combines the sunlight with carbon dioxide from the air and water from the soil to produce glucose (a form of sugar) and oxyg
On July 20, 1969, humanity achieved one of its greatest feats landing on the Moon. The Apollo 11 mission, led by NASA, was the first successful manned lunar landing. Astronauts Neil Armstrong, Buzz Aldrin, and Michael Collins were launched aboard the Saturn V rocket. After a four-day journey, Armstrong and Aldrin descended to the Moon's surface i
Airplanes are able to stay in the sky thanks to the balance of four fundamental forces lift, weight (gravity), thrust, and drag. Lift is the force that pushes the airplane upwards, generated by the wings as air flows over and under them. The shape of the wings creates lower air pressure on top and higher air pressure underneath, which results i
The origins of language are still a subject of much debate among linguists and anthropologists. One popular theory is that language developed gradually as early humans needed a way to communicate for survival. Early hominids likely used simple vocalizations and gestures to convey basic messages, such as the presence of food or danger. Over time, th
