An active learning sequence based on the predict-observe-explain teaching strategy is applied to a lesson on buoyant force. The results obtained clearly justify the use of this teaching method and suggest devising a series of activities to enable more effective removal of students' commonly held alternative conceptions regarding floating and sinking. © 2013 IOP Publishing Ltd.

Schools across the country participated in Iberdrola Renewables' #PowerOfWind contest. As we focus on the ins and outs of the wind industry every day, the vivid imagination of a child can often help us see familiar concepts in a whole new light. We hoped to capture some of that innovative thinking and creativity in this year’s #PowerOfWind school video competition. And boy, were we impressed by the results! Hundreds of students from schools across the country submitted videos throughout the fall, describing what they know about wind power, why it’s important, and how they would use it if they could harness all the wind in the world. Schools shared their submissions via social media, helping spark discussion around potential applications of wind energy among communities and families. Judges had a difficult task selecting a winner as future engineers proposed projects using wind to do almost anything, from creating homework to chocolate teddy bears. We also saw how schools are helping foster STEM education by incorporating wind energy into multiple areas of their classroom curricula. We even saw some incredible dance moves and musical talent. After much deliberation, our judges have announced that Van Wert Elementary School in Ohio, near the Blue Creek Wind Farm, is this year’s winner of the #PowerOfWind contest. The Van Wert class created an imaginative musical starring local “wind techs” and smart zoo animals who explain the benefits of wind power. There’s even an original song and dance celebrating the turbines in Van Wert. As the grand prize winner, Van Wert Elementary, will receive a $2,500 energy education grant from Iberdrola Renewables. Every school that participated will also receive a KidWind® advanced wind experiment classroom pack that allows students to discover advanced aspects of wind turbine technology and test different blade designs, gear ratios and generators. Congratulations to Van Wert Elementary and to all of our schools who participated this year and thank you to the teachers and parents who make clean energy education a priority for today’s students.

"Whistleblowers and experts allege safety violations, inadequate oversight surrounding new project near Indian Point". "BUCHANAN, N.Y. — The day before Halloween at Buchanan-Verplanck Elementary School in Westchester County, Courtney Williams watched her 5-year-old daughter participate in the school’s annual Pumpkin Olympics. As kindergartners balanced tiny gourds on wooden spoons and rolled big plastic pumpkins across the school’s lawn, the sound of heavy machinery competed with teachers for the children’s attention. The school is just 400 feet from the path of a massive new pipeline expansion project that’s being carried out by Spectra Energy, an oil and gas infrastructure company based in Houston. The Algonquin pipeline expansion is one of at least 22 pipeline projects designed in recent years to transport natural gas from shale fields across the U.S. to distribution points in the Northeast. But the noise isn’t the only thing troubling local residents like Williams. The pipeline will run within several dozen feet of electrical infrastructure necessary to operate Indian Point, an aging nuclear plant on the Hudson River. Residents worry that if the pipeline were to rupture, it could trigger a chain of events that might end in a nuclear meltdown, devastating their communities and turning New York City into a radioactive evacuation zone. 'It will be a catastrophe,' said Williams, a cancer researcher and mother of two small children. 'With [the pipeline] 400 feet from my front door, 400 feet from my kids’ elementary school, worrying about the worst case scenario is something I do on a routine basis.'"
NEW YORK (Reuters) - A tiny green lizard found by a New Jersey kindergarten student in a bundle of chilled salad greens at home has wriggled its way into the hearts of an entire elementary school class, which adopted it as a mascot. The three-inch (7.6-cm) critter went unnoticed for a few days in the refrigerator in Princeton, New Jersey, before Sally Mabon and her daughter Faye found its limp body while unwrapping a bunch of tatsoi, an Asian leaf, the Newark Star Ledger reported on Tuesday. Warmth restored its energy and soon the anole lizard was on its way to Riverside Elementary School, where it caught "oohs" and "aahs," like flies, and quickly became the class pet. Less Godzilla and more Geico Gecko, the lizard has been named "Green Fruit Loop" by the students. Fran McManus, spokeswoman for Whole Earth Center, the natural foods store where Mabon bought the tatsoi, told Reuters in a telephone interview that a Florida grower believes the lizard snuggled into the greens as they were being harvested in chilly temperatures and then woke up as a stowaway in New Jersey. The lizard's arrival in the Garden State has served as a learning experience for the students, Riverside's science teacher, Mark Eastburn, said in an email to Whole Earth. "It underscores that food doesn’t just come from the supermarket but from actual outdoor farms ... and that produce at Whole Earth Center is truly organic and gently harvested since a tiny lizard could survive the whole process without any harm,” the email said. Officials at Riverside Elementary School declined to immediately comment on the lizard lurking in the greens.
Obama cries as he describes the toll of gun violence in the country on Jan. 5. More In his call on Tuesday for stricter gun-control measures, President Barack Obama wiped away tears as he mentioned the December 2012 massacre of innocent children at Sandy Hook Elementary School. "First graders, in Newtown. First graders," Obama said, referencing the youngest victims of the Newtown, Connecticut, shooting. "Every time I think about those kids, it gets me mad. And by the way, it happens on the streets of Chicago every day." Many news stories on the president's speech noted his tears prominently — in the headline or the first few lines of the article — highlighting that it's still unusual to see a man crying publicly. But just what is the science behind male tears? It turns out that although men do cry, they may be biologically predisposed to cry less than women. Still, while male tears are less common and less intense, men weep at the same types of emotional triggers as women do, research suggests. What's more, Obama's ability to shed a few tears may even make viewers feel emotionally close to him, other research suggests. [15 Weird Things Humans Do Every Day, and Why] It's a well-worn stereotype: Women well up at sad news, weepy movies and even the odd diaper commercial, whereas men remain dry-eyed in the most harrowing and heartbreaking situations. But it turns out that the stereotype may actually have some grounding in fact. Women cry dozens of times a year, on average — up to five times more often than men do, on average, according to research reported by psychologists Ivan Nyklicek, Lydia Temoshok and Ad Vingerhoets, all of Tilburg University in the Netherlands, in their book "Emotional Expression and Health" (Routledge, 2004). Men's crying jags are also briefer, lasting just 2 to 3 minutes on average, compared with 6 minutes for women, the book says. (Women are also likelier to have marathon sob fests that last longer than an hour, according to Vingerhoets' research.) The weepier nature of women shows up in cultures around the world. However, in some poorer countries — such as Ghana, Nepal and Nigeria — people cry less overall, and men cry only slightly less than women, according to a 2011 study in the journal Cross-Cultural Research. That could be because poorer cultures dissuade emotional expression, while people in richer countries such as the United States sob more because the culture encourages it, the researchers hypothesized. The river of tears dividing men and women may have a biological basis. Women's higher levels of the hormone prolactin (which is involved in breast-feeding) may spur them to tears, whereas men's higher testosterone levels may inhibit tears, one theory holds. In fact, one 1998 study in the journal Cornea found that premenopausal women with lower levels of prolactin and higher testosterone levels shed fewer tears than women with high prolactin and low testosterone. And until puberty, with its hormonal onslaught that affects boys and girls very differently, both sexes cry about equally, according to a 2002 study in the British Journal of Developmental Psychology. Men's more stoic demeanor may be about simple geometry. Women have shallower, shorter tear ducts that are more easily overtopped, leading to more visible tears, according to a paper published in the 1960s in the American Journal of Physical Anthropology. Some researchers have argued that the gender difference in tears is at least partly cultural. Stories from long-ago cultures — including those in the Bible, "The Iliad" and the medieval knights' tales — are replete with sobbing, powerful, manly men. The discrepancy in male tears versus female tears may be a more recent phenomenon that began when men went to work in factories, according to the book "Crying: A Natural and Cultural History of Tears" (W. W. Norton & Co., 2001). Hard-charging bosses may have dissuaded emotional displays in order to increase productivity, and although some women went to work too, they were more likely than men to stay in the home, where tears were not so openly discouraged. Men who exhibit more "androgynous" traits, or those stereotypically defined as feminine, tend to cry more frequently than those with more stereotypically masculine traits, according to a 2004 study conducted by Kleenex. (The researchers don't report how "androgyny" was defined, nor was it clear that the study was peer reviewed, the standard process by which scientific research is vetted.)
