"We've all been told that we should recycle plastic bottles and containers. But what actually happens to the plastic if we just throw it away? Emma Bryce traces the life cycles of three different plastic bottles, shedding light on the dangers these disposables present to our world. "

"I'm in Minecraft, of course-the phenomenally popular, open-ended game that places players in a world in which they can live and build things infinitely. Marcus "Notch" Persson, the Swedish creator of Minecraft, started out by creating a simple game, allowing players to construct whatever they wanted, using a few different colored blocks, each equivalent to one cubic meter. Released in 2009, it has evolved into a massive, world-building video game in which players uses those blocks to create anything they can think of, from houses, caves, and machines to a scale version of the Death Star. Microsoft purchased Minecraft from Notch and his team for $2.5 billion in November 2014. There aren't any express objectives or any real way to win in Minecraft. It's a "sandbox," in gaming speak-offering free play without a specific goal and currently used by more than 18.5 million players, with some 20,000 more signing up every day. Users may choose between Creative Mode, in which they can build using unlimited resources by themselves or with friends, with no real danger or enemies, and Survival Mode, where they fend off enemies and other players and fight for resources and space. They can trade items and communicate using a chat bar. Modifications (or mods) can add complexity by creating things like economic systems that let players buy and sell resources from in-game characters using an in-game currency system. These downloadable mods can also add computer science concepts and thousands of additional features."

"When you have a dream - your own business, a great marriage, a career as an artist or an athlete - and you try for the dream but don't reach it, we call that failure. It hurts, failure. On the other hands. in places like Silicon Valley, failure is seen as good. It's practically a fetish, where never failing suggests you're not trying hard enough. And yet it seems only the winners preach that lesson. Are there times when giving up the dream makes the most sense? This hour On Point: failing - how we handle not getting what we want."

College students' lives can be changed - and even destroyed - in the time it takes to click a mouse. Take a look at these real-life examples of the harm digital technology can cause.

"Apple on Friday released an update to its iOS mobile operating system for the iPhone, iPad and iPod touch, addressing a potentially dangerous security flaw related to viewing PDF files in the Mobile Safari Web browser. iOS 4.3.4 can be downloaded and installed to any currently supported iOS-based devices by connecting to iTunes and choosing to update.

"It took just one relentless bout of the flu to remind me of the power of empirical evidence and the importance of shooting data. More than numbers, it was the evidence gleaned from my experiences and the images that I gathered along the way that helped my doctor solve the riddle that was delaying my recovery. My kids thought I was crazy, but I took some photos to save the evidence, and my doctor appreciated this. Gross? Absolutely. Helpful? Definitely! The doctor said that the pictures inspired him to take a different approach in my treatment. "Good data gathering," he joked, and I smiled, recalling one of my greatest pet peeves: educators and parents who rant about their disdain for this very important work. To listen to some, you'd think data are only numbers that shady reformers crunch in order to cash in on imaginary problems created by incompetent teachers. This is a dangerous assumption. The fact is that data are information that matter, and if they don't matter or if the conclusions we reach aren't helping us solve important problems, then we need to change the data we're collecting and the way we approach analysis. After all, isn't it a bit silly to blame data for our own faulty decision making?"

"As schools and districts attempt to continue improving student learning opportunities, there's a frightening trend emerging that might not have the intended consequences. In an effort to provide students more time with math and reading and other core area subjects, schools are cutting back on physical education courses, and recess opportunities are shrinking for students at the elementary levels. The dangerous trend of giving physical education the backseat to other 'more important' areas of learning might not yield the intended results. Here are five reasons why we need more physical activity in our schools and not less..."

"It's not hyperbole to say that we're in danger of losing a generation of children to a world that, at the moment, cannot find its way forward without violence, conflict, and despair. It's not just war and violence that threaten, but a crumbling of the infrastructure of good thinking. That sounds vague, but we witness its impact daily. What we see around us is an increasing inability to collectively define and outline a satisfying vision of the future. Fear is rapidly replacing hope-and that's not a good formula for growing up whole. The news is particularly poignant as we transition into a new year, when much of the world aims to turn love and good will from slogans into reality. So here's a question for educators to consider: How do teachers help heal the world in 2015 and beyond?"

"This article has been making its rounds in social media. I tend to agree with the idea that heavily-decorated, cutesy classrooms are distracting. I've never been a fan of a barrage of brightly-colored signs, Garfield posters and motivational phrases. However, I also see a real danger in district-mandated use of wall space. Here, the issue is less about bright and cutesy and more about things like word walls and anchor charts designed to create visual cues for learning. I see the point to it, but often this creates a text dump that students have to navigate (rather than having a simple notebook or website with tutorials they can access). It starts to feel like an encyclopedia had vomited on the walls. "
