"Last week Why Are There Clouds? was one of the most popular posts on the Free Tech for Teachers Facebook page. A good follow-up to that lesson is found in Where Does the Smell of Rain Come From? Produced by It's Okay to Be Smart, Where Does the Smell of Rain Come From? explains why we sometimes think we smell rain before a thunderstorm. Through the video we also learn about the role of petrichor in the lives of some animals."

"BOSTON - On the cramped urban campus of Boston Latin School, high-school students grow an acre's worth of vegetables in an old shipping container that's been transformed into a computer-controlled hydroponic farm. Using a wall-mounted keyboard or a mobile app, the student farmers can monitor their crops, tweak the climate, make it rain and schedule every ultraviolet sunrise. In a few decades, nine billion people will crowd our planet, and the challenge of sustainably feeding everybody has sparked a boom in high-tech farming that is now budding up in schools. These farms offer hands-on learning about everything from plant physiology to computer science, along with insights into the complexities and controversies of sustainability. The school farms are also incubators, joining a larger online community of farm hackers."

"Two years ago, I was asked to write an article for Knowledge Quest about how I created a maker space at Lamar Middle School in Flower Mound, TX. That first year of programming is so different from what I do now that I thought it pertinent to chart how our maker programming (#Makered) has evolved. During my first year as a librarian in 2012-13 my Teen Advisory Board (TAB) helped me redecorate a small office located behind our circulation desk. My director bought us some reading rockers, chalkboard paint, rain gutters, and 25 licenses for Minecraft."

Web cams, photo gallery, FAQ about butterflies. Active during the day, they live almost everywhere around the world, from Arctic tundra to tropical rain forests.

"Using simple analogies, real-life case studies, and state-of-the-art CGI, this special shows how the brain works, explains the frequent battle between instinct and reason, and unravels the mysteries of memory and decision-making. It takes us inside the mind of a soldier under fire to see how decisions are made in extreme situations, examines how an autistic person like Rain Man develops remarkable skills, and takes on the age-old question of what makes one person good and another evil. Research is rushing forward. We've learned more about the workings of the brain in the last five years than in the previous one hundred."

"With so many Raspberry Pi projects to choose from, it can be tricky to find the one you really want to build. Our advice is to find a way to marry the Pi with something you really love. One great example is TV and movie robots - iconic characters from popular sci-fi that can be rebuild at home with a Raspberry Pi built in. Once constructed, your robot might be able to utter commands when a condition is met (perhaps a sensor detects motion). Or it might move around, learning about its surroundings, or reading information to you from Wikipedia. Whatever you have in mind, it should be relatively straightforward to plan and execute. It may take some time, however. Here are five example projects that show how you can combine a Raspberry Pi 2 or later with your favorite fictional robot. 5 Things Only a Raspberry Pi 2 Can Do 5 Things Only a Raspberry Pi 2 Can Do The latest edition of the pint-sized computer is awesome. So awesome, in fact, that there's 5 things you can only do on a Raspberry Pi 2. READ MORE 1. R2-D2 We've all wanted our very own astromech droid, haven't we? Sure, no one on earth is (currently) operating a light speed drive, but Star Wars droid R2-D2 has far greater abilities than onboard spacecraft maintenance. For instance, he can hold torches, carry a tray of drinks, and launch lightsabers across pits in the desert. Okay, it's unlikely you'll manage to get your own R2-D2 robot to do that… but don't let that put you off. Check out this little guy, controlled by a Raspberry Pi. While this project was based on an existing R2-D2 toy, that shouldn't limit your ambition. You'll find plenty of R2-D2 builds on YouTube. There's a massive R2-D2 building community online. Finding one that has a drive unit should be ideal for integrating a Raspberry Pi (and perhaps an Arduino, which you can use the two together) and developing a more realistic R2-D2 experience. Arduino vs Raspberry Pi: Which Is The Mini Computer For You? Arduino vs Rasp

"People of all ages struggle to evaluate the integrity of the digital information that rains down with every web search and social media scroll. When the Stanford History Education Group released findings showing that most students couldn't tell sponsored ads from real articles, among other miscues, it intensified the scramble for tools and strategies to help students discern better. But a more recent study by Stanford's Sam Wineburg and Sarah McGrew suggests that many of the techniques that students and teachers employ - which include checklists and other practices most recommended for digital literacy - are often misleading. A better solution for navigating our cluttered online environment, they say, can be found in the practices of professional fact-checkers. Their approach, which harnesses the power of the web to determine trustworthiness, is more likely to expose dubious information. The following guidelines for interrogating online information, inspired by the fact-checkers' techniques, will increase students' odds of determining unreliable sources (and consuming reliable ones)."

The bushfire crisis that is currently impacting Australia is beyond devastating. The scale of these fires defies the imagination. For so long now we have lived with skies laden with smoke as a constant and inescapable reminder that this is not an ordinary summer. This is weather and drought at its most extreme. Our only salvation will be rain but this is not the season for that and the long term forecasts are not promising. Our young people, in particular, will be affected and will need special care in the weeks and months to come. What might this mean for schools and for student agency?
