In an efficient and safe effort to save us from the ill-effects of plastic waste, Akinori Ito has developed a machine which converts plastic back into oil. The machine produced in various sizes, for both industrial and home uses, can easily transform a kilogram of plastic waste into a liter of oil, using about 1 kW·h of electricity but without emitting CO2 in the process. The machine uses a temperature controlling electric heater instead of flames, processing anything from polyethylene or polystyrene to polypropylene (numbers 2-4). Comment: 1 kg of plastic produces one liter of oil, which costs $1.50. This process uses only about 1 kW·h of electricity, which costs less than 20 cents!

These apply to aviation and aerospace as well. "Math used in professional auto racing involves every type of math learned in school today.

"K-12math.info is a bibliographic information system used by elementary and secondary school mathematics material developers, teacher trainers, resource professionals and home schooling parents. K-12math.info uses a list of 1,000 of the most common terms that appear in elementary and secondary school student editions of mathematics textbooks. It tracks which textbook contain which terms, on what page (for OER materials a link to where the term can be found), for what grade level, and how the term is being used. Information has been collected since the early 1970's to the present Open Education Resource (OER) textbooks series. And displayed in a spreadsheet format. "

"using QR Codes. How can we use them? They are an excellent way of directing students to content. Whether the content is a book in the Library, a YouTube video, a seminar room at a given time, it doesn't matter. What matters is working out an appropriate use."

"Apple released its free Apple Configurator utility for OS X, which allows you to use your Mac to create custom profiles for iOS devices and deploy them to users in your workplace. You can now address deployment frustrations by creating various profiles for the devices (such as one for office workers, and others for bosses and supervisors) that offer restrictions to hardware such as cameras and built-in services like FaceTime or the App Store, and also which allow you to specify which Apps can be used. When the profile is set up, you can then supervise the devices using it and make adjustments to the profile that are applied the next time the device is connected to the Mac (do keep in mind the device is wiped when updated in this way)."

"This site offers a growing bank of imaginative, highly visual teaching-aids developed for use with interactive whiteboards in 11-18 Schools. The resources are designed to be used as rich sources of visually stimulating material, making use of both animations and drag and drop interactivity. The appropriate Key Stage is indicated for each resource. "

"The use of computers and computer languages in education has been impressive in the last couple of years.  More and more school going kids use computers in the heart of all academic and personal development than ever. Such use has been phenomenal in helping improve classroom interactive learning, bettering student grades and improving competitiveness in a modern education setting, among others."

Aeronautical Calculations: What's with All Those Coefficients Anyway? When aircraft designers decide on the design specifications for a new aircraft, they develop a model that is tested in a wind tunnel. The data collected from wind tunnel tests are used to develop a comparison to how the aircraft will fly at full scale. They make these and other comparisons by using proven aeronautical equations using dimensionless coefficients.

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."

How can you engage your students and be sure they are learning the conceptual foundations of a lecture course? In From Questions to Concepts, Harvard University Professor Eric Mazur introduces Peer Instruction and Just-in-Time teaching -- two innovative techniques for lectures that use in-class discussion and immediate feedback to improve student learning. Using these techniques in his innovative undergraduate physics course, Mazur demonstrates how lectures and active learning can be successfully combined. This video is also available as part of another DVD, Interactive Teaching, which contains advice on using peer instruction and just-in-time teaching to promote better learning.

The purpose of the Open Video Project is to collect and make available a repository of digitized video content for the digital video, multimedia retrieval, digital library, and other research communities. Researchers can use the video to study a wide range of problems, such as tests of algorithms for automatic segmentation, summarization, and creation of surrogates that describe video content; the development of face recognition algorithms; or creating and evaluating interfaces that display result sets from multimedia queries. Because researchers attempting to solve similar problems will have access to the same video content, the repository is also intended to be used as a test collection that will enable systems to be compared, similar to the way the TREC conferences are used for text retrieval.

"One of the biggest challenges in teaching science, technology, engineering, and math is capturing the students' imaginations long enough for them to see all of the possibilities that lie ahead," the company wrote on the Learn with Portals site. "Using interactive tools like the Portal series to draw them in makes physics, math, logic, spatial reasoning, probability, and problem-solving interesting, cool, and fun, which gets us one step closer to our goal-engaged, thoughtful kids!"

"Hay fever, allergy, and asthma - a lot of people use these terms interchangeably. In reality, they are completely different disorders. Use of the terms and medications incorrectly can have far reaching implications, including possible grounding by the FAA. Treatment is often available, both by over the counter and prescription medicines, but only a few medications may be used while flying."

"Students will use the Density=Mass/Volume formula to calculate the density of an unknown mineral. By using water displacement and a triple beam balance students will collect measurements of volume and mass for an unknown mineral. With this data, they will calculate the mineral's density then identify the mineral based on calculated density."
