Talia Milgrom-Elcott looks at the tension between the eagerness for STEM learning that young children possess, and the capacity of their busy PK-5 teachers to satisfy their curiosity through hands-on learning and success stories from the field of PK-5 STEM education.
When I was at elementary school, my teacher told me that matter exists in three possible states: solid, liquid and gas. She neglected to mention plasma, a special kind of electrified gas that's a state unto itself.
The number of electric vehicles on roads worldwide rose to a record high of 3.1 million in 2017, but more research, policies and incentives are needed to drive further uptake, the International Energy Agency (IEA) said.
Hurricane Maria and its chaotic aftermath in Puerto Rico led to at least 4,645 deaths, according to a new estimate based on household surveys. That’s thousands more than the 64 official storm-related deaths counted from death certificates. The Category 5 storm hit the U.S. Caribbean territory on September 20, 2017, bringing down trees, houses and the electricity system.
Vitamin and mineral supplements are a staple in many people's diets, but there is increasing evidence to suggest the most popular ones are essentially useless.
A new systematic review of data and trials published between January 2012 and October 2017 found that many popular multivitamins – as well as vitamin C, vitamin D, and calcium supplements – had no real advantage to people's health and that there was no evidence taking them reduced the risk of cardiovascular disease, heart attack, stroke, or early death.
The famed EM Drive is a bust - that's the take-home message from a team of physicists who have tested the controversial fuel-less propulsion system that appears to produce thrust while violating Newton's third law.Which means physics as we know it might be safe for a little bit longer.
Field experiments add vitamins to list of nutrients at risk from a changing atmosphere.By the end of this century, rice may not deliver the same B vitamin levels that it does today. Protein and certain minerals will dwindle, too, new data suggest.
Humankind is pathetically lightweight in comparison to the mass of almost all other living things on Earth, but while our bodies (and thinking) may be tiny, our crushing footprint is not.The most comprehensive study ever of the weight of all living biomass on the planet has discovered humans account for only about 0.01 percent of life on Earth – but despite our physical insignificance compared to the teeming masses around us, history shows there's no doubt over whose dominion this is.
The fragile apparition endured only long enough to say: “Help me Obi Wan Kenobi, you’re my only hope” before flickering out. But R2D2’s 3D projection gave millions of young eyes, including mine, their first taste of holograms, and planted unrealistic expectations of a future playing dejarik, the gruesome game of holographic chess played on board the Millennium Falcon

The Kīlauea volcano in Hawaii began causing earthquakes on Wednesday afternoon, after morning explosions of "ballistic blocks" three times larger than bowling balls.Earthquakes up to 4.4 magnitude have been measured after Kilauea's caldera, one of its large craters, dropped 90cm causing nearby faults to move.
Scientists have detected an unexpected rise in atmospheric levels of CFC-11, a chlorofluorocarbon (CFC) highly damaging to the ozone layer. Banned by the Montreal Protocol in 1987, CFC-11 was seen to be declining as expected but that fall has slowed down by 50% since 2012. Researchers say their evidence shows it's likely that new, illegal emissions of CFC-11 are coming from East Asia.
Kilauea isn’t about to become another Krakatoa. So let’s just stop that rumor right there.
Twitter was awash last weekend in indignant volcanologists responding to a now-corrected Associated Press story that appeared to link the Hawaii volcano to the so-called Ring of Fire, and suggest its eruption could spark others in the ring. That’s just wrong, for a number of reasons.
Wild flowers are being driven off Britain's roadside verges by air pollution and poor management, the charity Plantlife claims.
It says emissions from vehicle exhausts are acting as a fertiliser for a group of nitrogen-loving plants like nettles, which outcompete traditional flowers.
Sometimes mushroom hunting can yield much more than you bargain for. In the case of a forest delver in Minnesota, the discovery was straight out of a twisted tale on mutant creatures - a deceased, two-headed deer fawn.
A crucial period for language learning may extend well into teen years, a new study suggests.EmailPrintTwitterFacebookRedditGoogle+
Language learning isn’t kid stuff anymore. In fact, it never was, a provocative new study concludes.
A crucial period for learning the rules and structure of a language lasts up to around age 17 or 18, say psychologist Joshua Hartshorne of MIT and colleagues.
Sometimes the most amazing discoveries can happen just by chance. Case in point: an international team of astronomers accidentally photographed what they think is a planet in the process of growing bigger, 600 light-years away.
Cracks open in the ground. Lava creeps across roads, swallowing cars and homes. Fountains of molten rock shoot up to 70 meters high, catching treetops on fire.
After a month of rumbling warning signs, Kilauea, Hawaii’s most active volcano, began a new phase of eruption last week.
After a successful 2017 Kickstarter campaign, the Power Glove documentary – perfectly titled 'The Power of Glove' – is starting to hit the public sphere and what we've seen so far is everything we could have asked for.
A new kind of navigation system could help self-driving cars take the road less traveled. Most autonomous vehicles test-driving in cities navigate using 3-D maps marking every curbside and off-ramp with almost centimeter-level precision. But there are millions of miles of open road that tech companies aren’t likely to plot in such detail any time soon.

Ornithologists have classified the Vogelkop superb bird-of-paradise as its own species after recognizing differences in two similar-looking kinds of the birds.These birds-of-paradise are famous for evolving super-black feathers that absorb nearly all light, and their haunting courtship dances (see video below). But now scientists have discovered there are actually two species.
Exclusive: panel told researcher Aleksandr Kogan that Facebook’s approach fell ‘far below ethical expectations’. A Cambridge University ethics panel rejected research by the academic at the centre of the Facebook data harvesting scandal over the social network’s “deceptive” approach to its users privacy, newly released documents reveal.
Record levels of microplastics have been found trapped inside sea ice floating in the Arctic. Ice cores gathered across the Arctic Ocean reveal microplastics at concentrations two to three times higher than previously recorded. As sea ice melts with climate change, the plastic will be released back into the water, with unknown effects on wildlife, say German scientists.
A survey of hundreds of galaxies found a clear link between their shapes and their stars’ ages, astronomers report April 23 in Nature Astronomy. Galaxies with younger stars are more squashed into flatter shapes, while galaxies with older stars are more blobby, says astronomer Jesse van de Sande of the University of Sydney.
Astronomers have finally figured out what the clouds of Uranus consist of - and as it turns out, they smell terrible. For the first time, there's been a clear detection of hydrogen sulfide, the gas that gives rotten eggs - and flatulence - their dist

There's a surprising amount of order in this chaotic Universe of ours, but this is a pretty weird one - astronomers have found that all galaxies, regardless of their size, take around one billion years to complete a full rotation.
An emerging field that has generated a wide range of interest, spin caloritronics, is an offshoot of spintronics that explores how heat currents transport electron spin. Spin caloritronics researchers are particularly interested in how waste heat could be used to power next-generation spintronic devices. Some of these potential devices range from ultrafast computers that need next to no power, to magnetic nanoparticles that deliver drugs to cells.
Of all of the brain's functions, it's probably fair to say its ability to produce consciousness is the most challenging for us to make sense of.To better understand how our grey matter accomplishes this perplexing task, researchers from the University of Michigan's Center for Consciousness Science have taken a closer look at what the brain is doing when it's drifting into unconsciousness.
Scientists observe a signature on the sky from the very first stars to shine in the Universe.They did it with the aid of a small radio telescope in the Australian outback that was tuned to detect the earliest ever evidence for hydrogen. This hydrogen was in a state that could only be explained if it had been touched by the intense light of stars.
Early plants made Earth muddier. Ancient riverbed deposits of mud rock — rocks containing bits of clay and silt smaller than grains of sand — began increasing around 458 million years ago, around the time that rootless plants became common across Earth, researchers say.
In recent years, scientists have been uncovering potential therapeutic benefits of psychedelic substances like psilocybin and lysergic acid diethylamide (LSD) - it looks like they can 'reset' the brain in people with mental health conditions.

The European Union is preparing legislation to force companies to turn over customers' personal data when requested even if it is stored on servers outside the bloc, a position that will put Europe at loggerheads with tech giants and privacy campaigners.
What is inside an atom between the nucleus and the electron? Usually there is nothing, but why could there not be other particles too? If the electron orbits the nucleus at a great distance, there is plenty of space in between for other atoms. A "giant atom" could be created, filled with ordinary atoms. All these atoms form a weak bond, creating a new, exotic state of matter at cold temperatures, referred to as Rydberg polarons.
It's another demonstration of the power of Big Data - of mining a huge batch of statistics to see patterns of behaviour that were simply not apparent before.Satellite tracking shows fishing's footprint on Earth is now over four times that of agriculture.
One photon can transmit information in two directions at once.Communication is a two-way street. Thanks to quantum mechanics, that adage applies even if you’ve got only one particle to transmit messages with.
SpaceX turned heads around the world on February 6 with the first-ever launch of Falcon Heavy.The 230-foot-tall (70 metres tall) rocket's three boosters helped push Elon Musk's Tesla Roadster into space, peeled off after running low on fuel, and then careened toward Earth.
Fishing has left a hefty footprint on Earth. Oceans cover more than two-thirds of the planet’s surface, and industrial fishing occurred across 55 percent of that ocean area in 2016, researchers report in the Feb. 23 Science. In comparison, only 34 percent of Earth’s land area is used for agriculture or grazing.
