Sustaining Seven Billion People

Sustaining Seven Billion People | STEM Connections | Scoop.it

"With seven billion people now living on Earth, the ever growing demand is putting unprecedented pressure on global resources—especially forests, water, and food. How can Earth’s resources be managed best to support so many people? One key is tracking the sum of what is available, and perhaps nothing is better suited to that task than satellites."

Daniel LaLiberte's curator insight, July 6, 2014 12:09 PM

Such studies of the agriculture around the world are essential. The way we are doing agriculture to support seven billion people now, peaking at 9-10 billion in another 60 years, it is clear that we are putting severe strains on the environment.  But we have grown lazy, and we are doing it all wrong.

 

We CAN drastically reduce the amount of meat we consume, and thus quickly reduce the amount of arable land we need.  We CAN grow plants in ways that actually sequester more carbon and improve the soil it over time rather than erode and degrade.  And we CAN in fact grow all the food we need in the space we live in, thus enabling us to recycle all the water used as well, which is mostly just lost in evaporation.

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."

Jim Lerman's insight:

 

This interesting article explains how many companies are using the affordances provided by Meerkat and Periscope on social media sites such as Twitter, Facebook, Snapchat, and Instagram in order to win customer attention. The techniques themselves are interesting and creative educators will surely find ways to harness this delivery system in service to their students.

7 ways data collection is improving STEM education

7 ways data collection is improving STEM education | STEM Connections | Scoop.it
One district is getting students more active and analytical with data-collection tools, like probeware


Today’s students, being technology natives, expect the same kinds of engagement in the classroom as they seek out online. STEM classes in particular have a natural potential to be both tech-rich and inquiry-based, especially hands-on lab activities. The recent addition of probeware—sensory-based handheld devices for measuring things like water quality, light, and temperature—has allowed us to bring students out into nature and introduce them to the world of data collection and analysis. Here are 7 ways technology is enhancing and expanding STEM education in our school district.
