Both Voyager spacecraft are outfitted with 10 science instruments, including two cameras capable of taking detailed images of planets and their rings, magnetic fields and the interaction between light as a wave and particles. Voyager 1 returned a haunting portrait of Earth in 1990 that Carl Sagan called “Pale Blue Dot.” Since then, its data…
Students can act out the life cycle of a plant. Start by having students curl themselves into tight balls as seeds. Under optimal conditions, seeds sprout and become seedlings, before developing into mature plants producing flowers and setting seeds which are dispersed through wind, water or animals, continuing the cycle. Seed Every plant begins life…
We currently possess 8,400 publicly available photos of the Moon, hundreds of hours of video footage, and mountains of scientific data pertaining to its formation and structure – plus 382 kilograms of Moon rock! On July 20, 1969, Neil Armstrong and Edwin “Buzz” Aldrin from Apollo 11 became humanity’s first steps on another world. Six…
President Kennedy pledged that by the end of this decade, one person would land on the moon through Apollo missions. This timeline charts their history. On 20 July, Armstrong and Aldrin prepared for their lunar landing by unhinging Eagle from Collins’ command module and docking it to their lunar module Eagle. Apollo 1 President John…
Heath McKenzie brings brilliant fun and entertainment to the science of light and colour, starting with his audience-pleasing WHY? question. His illustrations and humor will surely become firm favorites among children of all ages. Sky BLUE took an early advantage, when Kerr sent a pass to Raquel Rodriguez who deftly maneuvered past two Portland defenders…
The sky is actually an intricate mosaic of many colors depending on time of day and weather conditions, with blue being created by sunlight being scattered by particles in the atmosphere – shorter wavelengths like blue tending to be scattered more often than others such as violet. Air molecules scatter blue light, while larger particles…
Armstrong and Aldrin returned from their 21-hour 38-minute stay on the Moon to Collins using Eagle’s ascent engine, performing numerous science tasks during their return and even installing a seismometer to study Moon quakes long after they had left Earth. At the Sea of Tranquility, a computer alarm went off. Armstrong quickly switched over to…
First time ever in history, a spacecraft has touched the Sun. NASA Parker Solar Probe flew into its outer atmosphere – known as corona – and unveiled phenomena long predicted but never directly observed before. Astrophysicist and namesake of this organization, Astrid Petri is dedicated to unlocking the mysteries of solar wind that streams out…
Flowers come in all sorts of shapes, colors and scents; their main purpose being to attract pollinators insects while producing seeds that perpetuate the species. Seeds contain miniature plants called embryos. Each seed has a hard shell called a seed coat to protect it, which allows germination to occur quickly. Once sprouting occurs, embryos develop…
