" kids keep coming back for more and more play time. We loved their statement, "Let's show our children that Math and Science can be loved." Numerosity may not have coined the term Gameful Learning, but they refer to it often and explain it as a way to engage and empower learners by placing them in the driving seat."

"Portals → Technology → Engineering - The Engineering Portal Engineering is the application of science, technology, mathematics, art, and practical experience to the design and production of objects, tools or processes."

"Environmental engineering is the integration of science and engineering principles to improve the natural environment (air, water, and/or land resources), to provide healthy water, air, and land for human habitation (house or home) and for other organisms, and to remediate pollution sites. Further more it is concerned with finding plausible solutions in the field of public health, such arthropod-borne diseases, implementing law which promote adequate sanitation in urban, rural and recreational areas. It involves waste water management and air pollution control, recycling, waste disposal, radiation protection, industrial hygiene, environmental sustainability, and public health issues as well as a knowledge of environmental engineering law. It also includes studies on the environmental impact of proposed construction projects."

"The first Women's Air Derby during the 1929 National Air Races, commonly known as the "Powder Puff Derby", was the first official women-only air race in the United States. Nineteen pilots took off from Santa Monica, California, on August 18, 1929 (another left the next day). Fifteen made it to Cleveland, Ohio, nine days later."

"The games section of Try Engineering features 29 games. Some of the games were developed specifically for Try Engineering while others are hosted on other educational sites like those of NASA and PBS. Like the lesson plans, the games collection cover a variety of topics including solar energy, space science, and bio-engineering."

"The most important gas which leads to acidification is sulfur dioxide. Emissions of nitrogen oxides which are oxidized to form nitric acid are of increasing importance due to stricter controls on emissions of sulfur containing compounds. 70 Tg(S) per year in the form of SO2 comes from fossil fuel combustion and industry, 2.8 Tg(S) from wildfires and 7-8 Tg(S) per year from volcanoes.[24]"

"The assembly of the International Space Station is a major aerospace engineering endeavour being conducted in Low Earth orbit by a consortium of governmental and inter-governmental space agencies."

"The Wright Flyer (often retrospectively referred to as Flyer I or 1903 Flyer) was the first powered aircraft, designed and built by the Wright brothers. They flew it four times on December 17, 1903 near the Kill Devil Hills, about four miles south of Kitty Hawk, North Carolina, U.S."

"En route to the Moon, approximately 200,000 miles (320,000 km) from Earth, Mission Control asked Swigert to turn on the hydrogen and oxygen tank stirring fans, which were designed to destratify the cryogenic contents and increase the accuracy of their quantity readings. Approximately 93 seconds later, just under 56 hours since launch, the astronauts heard a "loud bang", accompanied by fluctuations in electrical power and firing of the attitude control thrusters.[6] The crew initially thought that a meteoroid might have struck the Lunar Module (LM)."

"The mission of Stennis and her embarked Air Wing (CVW-9) is to conduct sustained combat air operations while forward deployed in the global arena. The embarked Air Wing consists of eight to nine squadrons. Attached aircraft are Navy and Marine F/A-18 Hornet, EA-6B Prowler, MH-60R, MH-60S, and E-2C Hawkeye. The Air Wing can engage enemy aircraft, submarines, and land targets, or lay mines hundreds of miles from the ship. Stennis's aircraft are used to conduct strikes, support land battles, protect the Battle Group or other friendly shipping, and implement a sea or air blockade. "
