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 Science of Sharing | Exploratorium | STEM Connections | Scoop.it
Investigating Competition, Cooperation, and Social Interaction Are you competitive? Do you like to negotiate? How do you make decisions about sharing, helping, and collaborating with others? And how do scientists study these kinds of social interactions? Questions like these are at the heart of the Exploratorium’s new Science of Sharing exhibition. We’ve designed exhibits and activities to let you experiment with social interactions, play with strategies for working with others, and learn about the scientific study of human behavior.

Visualized: How the insane amount of rain in Texas could turn Rhode Island into a lake

Visualized: How the insane amount of rain in Texas could turn Rhode Island into a lake | STEM Connections | Scoop.it

"It's difficult to comprehend the ridiculous amounts of water that have fallen in such a short time in a state that, until recently, had been in the grip of a historic drought. But one place to start would be to look at reservoir levels in the state. In the past 30 days, Texas reservoirs have gone from being 73 percent full to 82 percent full, according to data maintained by the Texas Water Development board. All told, about 8 million acre-feet of water have flowed into the state's reservoirs."

Seth Dixon's curator insight, May 28, 8:44 AM

Just how much of water is 8 million acre-feet?  It's almost impossible for most people to visualize that, but this series of graphics is designed to put the scale of the recent flooding in Texas into perspective (and yes, I love that Rhode Island is almost a unit of measurement).

Educating. All Our Children

Educating. All Our Children | STEM Connections | Scoop.it
Bonnie Bracey Sutton's insight:

Who are the children in our schools?  What does ‘diversity’ mean when we’re talking about educating children?



One person I rely on to teach me about the children, their families and their cultures – and the policies we need to give every child a powerful education, is Angela Valenzuela, whose blog consistently challenges our often limited vision for our schools and our teaching.   

A recent post on her blog, Educational Equity, Policy and Politics in Texas, shows the need to look behind the official “diversity” categories if we want to understand our students, their families and the ways they experience school.  Most recently, Valenzuela highlights important findings on the languages spoken by people in our country officially designated as “Hispanic.”  “English Proficiency on the Rise Among Latinos,” a report by the Pew Research Center on Hispanic Trends, shows that even the languages we speak, and use on a daily basis, can’t be automatically assumed by typical demographic designations such as age, educational attainment, or country of birth.

The case for engineering our food

Pamela Ronald studies the genes that make plants more resistant to disease and stress. In an eye-opening talk, she describes her decade-long quest to help create a variety of rice that can survive prolonged flooding. She shows how the genetic improvement of seeds saved the Hawaiian papaya crop in the 1950s — and makes the case that it may simply be the most effective way to enhance food security for our planet’s growing population.

The Precision Agriculture Revolution

The Precision Agriculture Revolution | STEM Connections | Scoop.it

"Thousands of years ago, agriculture began as a highly site-specific activity. The first farmers were gardeners who nurtured individual plants, and they sought out the microclimates and patches of soil that favored those plants. But as farmers acquired scientific knowledge and mechanical expertise, they enlarged their plots, using standardized approaches—plowing the soil, spreading animal manure as fertilizer, rotating the crops from year to year—to boost crop yields. Over the years, they developed better methods of preparing the soil and protecting plants from insects and, eventually, machines to reduce the labor required. Starting in the nineteenth century, scientists invented chemical pesticides and used newly discovered genetic principles to select for more productive plants. Even though these methods maximized overall productivity, they led some areas within fields to underperform. Nonetheless, yields rose to once-unimaginable levels: for some crops, they increased tenfold from the nineteenth century to the present.  

Today, however, the trend toward ever more uniform practices is starting to reverse, thanks to what is known as 'precision agriculture.' Taking advantage of information technology, farmers can now collect precise data about their fields and use that knowledge to customize how they cultivate each square foot."

Development and diffusion of agriculture-

This article explains how agriculture has developed and grown for thousands of years, and today with our technology, we can do what seemed impossible to the past peoples.

This article represents Development and Diffusion of Agriculture by showing how in our past years, we could mostly only do substinence agriculture, but today with technology, we can do so much more, with so much less people.

Land use/land cover change: irrigation, desertification, deforestation, wetland destruction, conservation efforts to protect or restore natural land cover, and global impacts-

This article explains how today we have the best technology we have ever created agriculture-wise, but with this, more land has been used. But thanks to precision agriculture, we can use data to determine where we can use the least amount of raw materials needed, thus helping protect more land than before.

 This article demonstrates land use/land cover change: irrigation, desertification, deforestation, wetland destruction, conservation efforts to protect or restore natural land cover, and global impacts by showing how with the technology today and precision farming, we can use less raw materials than ever before, thus helping lessen global impact.

How Suburban Are Big American Cities?

How Suburban Are Big American Cities? | STEM Connections | Scoop.it

"What, exactly, is a city? Technically, cities are legal designations that, under state laws, have specific public powers and functions. But many of the largest American cities — especially in the South and West — don’t feel like cities, at least not in the high-rise-and-subways, 'Sesame Street' sense. Large swaths of many big cities are residential neighborhoods of single-family homes, as car-dependent as any suburb.

Cities like Austin and Fort Worth in Texas and Charlotte, North Carolina, are big and growing quickly, but largely suburban. According to Census Bureau data released Thursday, the population of the country’s biggest cities (the 34 with at least 500,000 residents) grew 0.99 percent in 2014 — versus 0.88 percent for all metropolitan areas and 0.75 percent for the U.S. overall. But city growth isn’t the same as urban growth. Three cities of the largest 10 are more suburban than urban, based on our analysis of how people describe the neighborhoods where they live."

Sammie Bryant's curator insight, May 27, 12:07 AM

This article accurately depicts the difference between a normal city 50 years ago and a city today, as well as the continuing spread of suburbanization. For example, Austin, the capital of texas, a hustling, bustling always busy area, is predominantly suburban. As cities and countries continue to advance and develop and its citizens become more successful and family oriented, suburban homes for families will become more needed than something smaller, like condos or studio apartments. As the needs of the cities change, the structure of the city changes as well. This applies to our final unit of APHUG: Cities and Urban Land Use.
