Jason Wilhelm's curator insight, February 27, 2014 11:33 AM

The large-scale agricultural practices of modern America tend to lend to the bad image of commercial farming. However, the practices are actually helping feed more people in the US, but they also use genetically modified crops and other highly debated techniques.

Lauren Sellers's curator insight, May 20, 2014 11:45 AM

Yes it does because in all large scale endeavors, regardless of what for, the quality is always sacrificed for the quantity because it becomes cheaper to produce and profits are greater.

BrianCaldwell7's curator insight, March 16, 3:56 PM

In the long run, a successful farmer needs to find a balance between economic and environmental sustainability.  Some big farms are working towards that so the 'big-equals-bad' narrative about agriculture may be easy, but it doesn't tell the whole story about modern agriculture.

STEM and Writing: A Super Combination - Edutopia

STEM and Writing: A Super Combination - Edutopia | STEM Connections | Scoop.it

"I brought a superhero into my classroom the other day. He wasn't wearing a cape. He didn't have an alias. But he had the greatest superpower of all: inspiration.

When you teach using project-based learning (PBL), one brings outside expertise into the classroom. My eighth graders begin the year creating science fiction based origin stories for original superhero characters as an introduction to a greater advocacy unit. Therefore, it seemed natural to bring in an actual scientist. Which brought me to CalTech and Dr. Spyridon Michalakis."

The Great Make: Rocketry Round-Up | Make: DIY Projects and Ideas for Makers

The Great Make: Rocketry Round-Up | Make: DIY Projects and Ideas for Makers | STEM Connections | Scoop.it
Many a Make: reader, especially those of us of a certain age, cut our teeth on building and flying model rockets. This one hobby required you to gain at least a basic aptitude in model construction (and all of the skill sets involved there), basic design and engineering skills, understanding the science and aerodynamics of flight, rudimentary electronics, ballistics, and much more.

Given the importance of rocketry for many of us in developing as makers, it’s no wonder that Make: has covered a ton of rocketry projects of varying stripes over the years, from kiddie water and stomp rockets to serious high-powered efforts. Here is a selection of some of these projects and articles from the past ten years.

The weird, wacky & cool energy ideas coming out of labs across the US | STEM Connections | Scoop.it
A fuel cell for space. Batteries that use air. A way to tap pine trees and extract biofuels like maple syrup from a maple tree. These are just some of the “out-there” energy innovations that researchers and entrepreneurs are hard at work building in labs across the U.S., and which were on display at the fifth annual energy innovation-focused ARPA-E Summit this week.

A Handwritten Card, Signed and Sealed by the Latest Technology

A Handwritten Card, Signed and Sealed by the Latest Technology | STEM Connections | Scoop.it
Communication today is faster and more ephemeral than ever. We fire off emails, skip the punctuation in our texts, and watch our photos and messages vanish in seconds on Snapchat.

Digital tools have made communicating with others easier but not necessarily more thoughtful, and this bothered Sonny Caberwal, an entrepreneur. “We’re in a rush to make everything disappear,” he said.

Receiving a physical, handwritten thank-you note or letter these days feels special, but it also requires some work. “You have to assemble all the pieces,” Mr. Caberwal said — including paper, a pen, the recipient’s address, an envelope and a stamp — and then the note has to be written and mailed, all of which is time-consuming. He wanted to enable people to do that more easily, by harnessing technology to create a product that still felt very personal and worth keeping.

His company, Bond, harks back to a time of fountain pens, creamy sheets of writing paper and wax-sealed envelopes. Mr. Caberwal, founder and chief executive of the New York City start-up, describes it as “the opposite of Snapchat.” Bond was started in 2013, and has about 50 full-time employees and several high-profile backers, like Gary D. Cohn, the president of Goldman Sachs, and the rapper Nasir Jones (known as Nas).

Elite Math Competitions Struggle to Diversify Their Talent Pool

Interest in elite high school math competitions has grown in recent years, and in light of last summer's U.S. win at the International Math Olympiad—the first for an American team in more than two decades—the trend is likely to continue.
But will such contests, which are overwhelmingly dominated by Asian and white students from middle-class and affluent families, become any more diverse?
Many social and cultural factors play roles in determining which promising students get on the path toward international math recognition. But efforts are in place to expose more black, Hispanic, and low-income students to advanced math, in the hope that the demographic pool of high-level contenders will eventually begin to shift and become less insular.

Amateur Scientists Will Love Science Journal, Google's New App | Make:

Amateur Scientists Will Love Science Journal, Google's New App | Make: | STEM Connections | Scoop.it

This morning, Google released Science Journal, its latest free app for Android phones. Science Journal is a digital science notebook that allows kids (and amateur scientists of all ages) to use the sensors on their Android phones for experiments. With a just a phone you can measure sound, light, and motion for some easy-access science!

The app itself is open-ended, providing the tools in a simple format that’s intuitive, but to really kick off the launch of this app Google has partnered with the experts at Exploratorium to create a number of hands-on projects. These projects are detailed on their companion site Making & Science, and kits are available to create projects around external sensors (including a kit from Make:!).

Combining physical experiences with digital experience is really the future of STEM education. Science Journal makes it easy for science educators to introduce the idea that science doesn’t need to be difficult or confined to the lab. With Science Journal on your phone, you have the basic tools you need to follow your curiosity and get started with experiments of your own.
