"Fused Deposition Modeling (FDM) 3D printers are popping up everywhere - from the home to the office; from the classroom to the workshop. PLA and ABS thermoplastic are the defacto standard materials used for these desktop 3D printers. But did you know that you could fabricate things with exotic 3D printer filament, too? You can now print in wood, metal, carbon fiber, and much more besides. As the name implies, exotic 3d printer filaments - also known as specialty or composite - filaments are advanced materials for your FDM 3D Printer. They combine thermoplastics like PLA and ABS with ingredients like metals, carbon fiber, wood, and glow-in-the-dark compounds to create hybrid materials with unique properties. With so much variety on offer, it's easier than ever to create functional, beautiful, and high performing prints in a variety of exciting materials. Read our guide to find out which 3D printer filament - regular or exotic - is right for you."

"In a new report, 24 researchers from eight different countries gathered to create a consensus on the impact of physical activity on kids' health. They focused primarily on studies that examined the health of children aged 6 to 18, and analyzed the effects of exercise on children's fitness, health, cognitive function, motivation, and mental and social health. The report defines physical activity as "an overarching term that consists of many structured and unstructured forms within school and out-of-school-time contexts, including organized sports, physical education, outdoor recreation, motor skill development programs, recess, and active transportation such as biking and walking." In short, they found that exercise was beneficial for nearly every aspect of a child's wellbeing: physical health, cognitive ability, motivation and psychological wellbeing, as well as social inclusion. First, exercise leads to improved cardiorespiratory fitness, which in turn improves brain development and intellect, they said."

"A paper circuit is a low-voltage electrical circuit that is created on paper or cardboard using conductive copper tape, LEDs and a power source such as a coin-cell battery.  Creating paper circuits is a good way to teach the basics of electricity and how circuits function.   In addition to being educational, they can also be a fun makerspace project that helps to bring artwork and paper craft to life.  By adding sensors, buzzers and motors to your circuit, you can also add another dimension of interactivity.  These simple projects are great for all ages and all makerspaces."

"n florida, a coalition of parents known as "the recess moms" has been fighting to pass legislation guaranteeing the state's elementary-school students at least 20 minutes of daily free play. Similar legislation recently passed in New Jersey, only to be vetoed by the governor, who deemed it "stupid." When, you might ask, did recess become such a radical proposal? In a survey of school-district administrators, roughly a third said their districts had reduced outdoor play in the early 2000s. Likely culprits include concerns about bullying and the No Child Left Behind Act, whose time-consuming requirements resulted in cuts to play. [1] Disadvantaged kids have been the most likely to be shortchanged: According to a 2003 study, just 56 percent of children living at or below the poverty line had recess, compared with 83 percent of those above the poverty line; a similar disparity was noted between black children and their white peers. [2] FROM OUR DECEMBER 2016 ISSUE Try 2 FREE issues of The Atlantic SUBSCRIBE The benefits of recess might seem obvious-time to run around helps kids stay fit. But a large body of research suggests that it also boosts cognition. Many studies have found that regular exercise improves mental function and academic performance. [3] And an analysis of studies that focused specifically on recess found positive associations between physical activity and the ability to concentrate in class. [4]"

"There are a lot of cool FREE Apps out there that can add functionality and sparkle to the number one picture and video App Instagram, but I'm going to share my favorite four! And yeah, I'm still mourning the loss of Vine. But, finding these new Apps has helped me get past the it... a little! "

"Root looks like a smoke detector but is actually a sophisticated robot. A magnetic surface, wheels, and an impressive arsenal of sensors allow it to navigate a classroom white board. But Root isn't actually programmed to do anything. Its tasks and functionality hinge on a child's imagination. To operate - Root needs instructions, a line of code. Zivthan Dubrovsky of Harvard's Wyss Institute recalls testing out Root with kids for the first time. He asked them this: "Can you make a text based java script line follower? They go 'no that's hard, can't do that', but we can put level one in front of them and they can do it in minutes." Level one introduces kids to principles of programming using an interface of simple instruction and pictures. As they become more adept, they jump to levels 2 and 3, at which point writing computer code becomes second nature, according to Dubrovsky."

"Empowerment of people through Media and Information Literacy (MIL) is an important prerequisite for fostering equitable access to information and knowledge and promoting free, independent and pluralistic media and information systems. Media and Information Literacy recognizes the primary role of information and media in our everyday lives. It lies at the core of freedom of expression and information - since it empowers citizens to understand the functions of media and other information providers, to critically evaluate their content, and to make informed decisions as users and producer of information and media content. Information Literacy and Media Literacy are traditionally seen as separate and distinct fields. UNESCO's strategy brings together these two fields as a combined set of competencies (knowledge, skills and attitude) necessary for life and work today. MIL considers all forms of media and other information providers such as libraries, archive, museums and Internet irrespective of technologies used"

"On the morning of Wednesday, February 22, 2017, my cell phone rang at 5:30 a.m. The caller ID told me that the call was from our school district. Even before I swiped to answer, the pop-up notification on my phone told me the nature of the call. School had been canceled for the day. That's not such an odd occurrence in February in southwest Missouri. Snow and ice have canceled school as late in the year as early May. However, we'd been enjoying a stretch of record high temperatures, and while I wasn't really awake enough for my rational mind to rule that out, I knew something was off. There has been a lot of construction to and around a few of the school buildings in our district. In December 2016, I happened to be privy to a conversation regarding low water pressure at one of the schools due to a water main issue at a construction site near that particular school. So, non-functioning utilities was certainly a possibility for canceling school that zipped through my not-yet-awake mind. I was not prepared for what the recorded voice of our district superintendent told me. School had been canceled because of the threat of violence."

"If a school were to spend thousands of dollars on a class set of laptops, yet only use them for printing documents of random words or clipart designed by someone else, no one in their right mind would conclude that this technology was being used to its fullest extent. Yet, many schools are not prepared to hold their 3D printing programs to the same educational standards. At Brookwood School in Manchester-By-The-Sea, MA, when our first 3D printing project in 2013 resulted in a functional prosthetic for my son, it quickly became clear that these machines held the potential for some pretty transformative educational experiences, and set us on a path to getting the most out of this new technology. Below are some recommendations regarding how to "supercharge your 3D printing program":"

"The newer versions of iOS include a fantastic text to speech engine that lets you select any text and have it spoken to you. This basically means you can have an iPhone, iPad, or iPod touch read you the content of any web page, notes, text files, or even eBooks and iBooks. Before you can use the text to speech function though, you have to enable it."
