"A "How it's made" video showing how they make something that makes other things. Specifically, a laser cutting machine. The coolest thing we didn't know before seeing the video is that a laser beam must be the appropriate shape in order to cut optimally, just like a router bit or a kitchen knife designed for a specific task.

"The legal jargon with respect to digital copyrights can be confusing - especially since different countries have their own laws and regulations. With this post, we hope to dispel a few myths and pull together a complete list of resources for teachers and students to use when blogging and working with content online."
"Your Research Mission, a dynamic project showcase. Each week, it will feature curated citizen science tasks, ranging from analyzing distant galaxies to monitoring frog, firefly and whale populations, to detecting home and body microbiomes. The projects will make it simple for everyone to jump in and get their hands dirty with science."
"Neurons-the electrically excitable cells that make up the brain and nervous system-first fascinated me in high school. In college, like so many other students studying the brain, I dutifully memorized the structure of the archetypal neuron. I also remember learning about a few different types of neurons with different shapes and functions: motor neurons that make muscles twitch, for example, and unique sensory neurons in the eyes and nose."
"find a local ham radio group to help you host a contact with NASA astronauts in space onboard the International Space Station. Holiday Ham for NASA, get it?"
"Engineering and fun aren't always two things that kids naturally associate with one another, but there are hundreds of ways to make engineering, physics and design fun and challenging for kids. Here are 100 great experiments that will let kids construct, play, learn and grow, all while they study the fundamentals of engineering."
Welcome to the Mathematical Association of America's NumberADay blog. Every working day, we post a number and offer a selection of that number's properties.
Digital Public Library of America (DPLA). On this website, users can learn about their ongoing work via their blog and the very useful "Workstreams" section of the site. In this area, visitors can sign up to learn about the different segments of the DPLA management team, which include "Content & Scope", "Governance", and "Legal Issues".

"Introducing AOPA AV8RS, AOPA's new youth membership free to teens aged 13 to 18. Through AV8RS, you'll be introduced to the world of aviation and given the support and encouragement to pursue your dreams and aspirations.
AV8RS membership includes a digital subscription to Flight Training magazine, access to members-only content on aopa.org, special AV8RS social communities through Facebook, YouTube, Twitter, and tumblr, a dedicated AV8RS blog, opportunities to win flight training scholarships and more. "
"The final experiments involving Alex - a grey parrot (Psittacus eithacus) trained to count objects - have just been published. They show that Alex could accurately add together Arabic numerals to a sum of eight and three sets of objects, putting his mathematical abilities on par with (and maybe beyond) those of chimpanzees and other non-human primates"
"To celebrate Moon Day, catch up on the latest in lunar exploration and space travel. The ideas worth sharing here are the first steps in the next giant leap for mankind."
"coaxial rotors, uses a pair of helicopter rotors mounted one above the other to produce both lift and thrust. Sikorsky's high speed technology demonstrator the X2 uses this design as well as many Russian helicopters.
To neutralize the torque, the rotors spin in opposite directions creating equal and opposite torques that cancel each other and eliminate the need for a tail rotor. Yaw control is achieved by increasing the collective pitch of one rotor and decreasing the collective pitch on the other. "
"A report by Pew Research Center's Internet and American Life Project indicated that 73 percent of teachers use cell phones for classroom activities. Educational apps open a world of possibilities for teachers and students. The growing pool of grade- and subject-specific apps can keep students engaged and make teachers' lives easier."

collection focuses on The Pacific War, a term referring to parts of World War II that took place in the Pacific Ocean, the islands of the Pacific and the Far East. The start of The Pacific War is generally considered to be the Japanese attack on Pearl Harbor, Hawaii on December 7, 1941.
The Super Book of Web Tools for Educators
There are many teachers who want to start using technology in their classrooms, but just aren't sure where to start. That's why I got together ten prominent ed tech bloggers, teachers, and school administrators to create The Super Book of Web Tools for Educators. In this book there introductions to more than six dozen web tools for K-12 teachers. Additionally, you will find sections devoted to using Skype with students, ESL/ELL, blogging in elementary schools, social media for educators, teaching online, and using technology in alternative education settings."
