"There was a part of me that was very nervous about it," Donna McBride, a first-grade teacher at the school, told TODAY Parents.

"I was trying to wrap my head around my class going outside four times a day and still being able to teach those children all the things they needed to learn."

Some five months into the experiment, McBride's fears have been alleviated. Her students are less fidgety and more focused, she said. They listen more attentively, follow directions and try to solve problems on their own instead of coming to the teacher to fix everything. There are fewer discipline issues.

"We're seeing really good results," she noted.

Parents are seeing them, too.

This is the fuel NASA needs to make it to the edge of the solar system — and beyond | Chelsea Harvey | WashPost.com | Banco de Aulas | Scoop.it

Just in time for the new year, researchers at the Department of Energy’s Oak Ridge National Laboratory have unveiled the fruits of a different kind of energy research: For the first time in nearly three decades, they’ve produced a special fuel that scientists hope will power the future exploration of deep space.

The fuel, known as plutonium-238, is a radioactive isotope of plutonium that’s been used in several types of NASA missions to date, including the New Horizons mission, which reached Pluto earlier in 2015. While spacecraft can typically use solar energy to power themselves if they stick relatively close to Earth, missions that travel farther out in the solar system — where the sun’s radiation becomes more faint — require fuel to keep themselves moving.

Plutonium-238 satisfies this need by producing heat as it decays, which can then be converted into electricity by NASA’s radioisotope power system, a kind of nuclear battery called the Multi-Mission Radioisotope Thermoelectric Generator, or MMRTG. Excess heat from the MMRTG can also be used to keep some spacecraft systems from freezing in cold environments — a service it’s been providing for the Curiosity rover on Mars, for instance.

While other isotopes could theoretically also get the job done, plutonium-238 is ideal because of its “unique combination of properties,” said Rebecca Onuschak, a program director in the Department of Energy’s Office of Space and Defense Power Systems. Most notably, it’s safer to work with than many other types of radioactive materials.

We know that the Earth and the solar system are located in the Milky Way galaxy. But how, exactly, does the Milky Way fit in among the billions of other galaxies in the known universe?

In a fascinating 2014 study for Nature, a team of scientists mapped thousands of galaxies in our immediate vicinity, and discovered that the Milky Way is part of a jaw-droppingly massive "supercluster" of galaxies that they named Laniakea.

This structure is much, much, much bigger than astronomers had previously realized. Laniakea contains more than 100,000 galaxies, stretches 500 million light years across, and looks something like this (the Milky Way is just a speck located on one of its fringes on the right):

Chemicals That Make Plants Defend Themselves Could Replace Pesticides - Elsevier (2015)

Chemical triggers that make plants defend themselves against insects could replace pesticides, causing less damage to the environment. New research... identifies five chemicals that trigger rice plants to fend off a common pest – the white-backed planthopper, Sogatella furcifera

 

Pesticides are used around the world to control insects that destroy crops... One of the problems with many pesticides is that they kill indiscriminately. For rice plants, this means pesticides kill the natural enemies of one of their biggest pests, the white-backed planthopper... This pest... causes the plants to wilt and can damage the grains. It also transmits a virus disease... which stunts the plants’ growth and stops them from “heading,” which is when pollination occurs.

 

Left untreated, many of the insects’ eggs would be eaten, but when pesticides are used these hatch, leading to even more insects on the plants. What’s more, in some areas as many as a third of the planthoppers are resistant to pesticides... “Therefore, developing safe and effective methods to control insect pests is highly desired”... 

 

Because of the problems of using pesticides, it’s vital to find new solutions to help protect rice plants from infestation. Plants have natural self-defense mechanisms that kick in when they are infested with pests like the planthopper. This defense mechanism can be switched on using chemicals that do not harm the environment and are not toxic to the insects or their natural enemies... 

 

Researchers... developed a new way of identifying these chemicals. Using a specially designed screening system, they determined to what extent different chemicals switched on the plants’ defense mechanism... The researchers used bioassays to show that these chemicals could trigger the plant defense mechanism and repel the white-backed planthopper. This suggests that these chemicals have the potential to be used in insect pest management... 

 

“This new approach to pest management could help protect the ecosystem while defending important crops against attack.”

The next step for the research will be to explore how effective the chemicals are at boosting the plants’ defenses and controlling planthoppers in the field.

Its good to see more research in these areas - but it would be good if in parallel we looked at potential impact of activated and elevated triggers and response  in terms of ecosystems and human health.  Multi-systemic approaches are going to be increasingly needed, which is worrying given how limited funding in this area already is..

Uruguay makes dramatic shift to nearly 95% electricity from clean energy | Jonathan Watts | The Guardian | Banco de Aulas | Scoop.it

As the world gathers in Paris for the daunting task of switching from fossil fuels to renewable energy, one small country on the other side of the Atlantic is making that transition look childishly simple and affordable.

In less than 10 years, Uruguay has slashed its carbon footprint without government subsidies or higher consumer costs, according to the country’s head of climate change policy, Ramón Méndez.

In fact, he says that now that renewables provide 94.5% of the country’s electricity, prices are lower than in the past relative to inflation. There are also fewer power cuts because a diverse energy mix means greater resilience to droughts.

It was a very different story just 15 years ago. Back at the turn of the century oil accounted for 27% of Uruguay’s imports and a new pipeline was just about to begin supplying gas from Argentina.

Communities around the world aren’t waiting for global leaders to take action on climate change. They’re taking action now.

This episode of In the World, an original series by Fusion, highlights three communities that have already transitioned away from fossil fuels to run completely on renewables.

One of communities featured, Burlington, Vermont, was featured on EcoWatch earlier this year when it became the first U.S. city of any decent size to run on renewable electricity. The other two communities—Dardesheim, Germany and Dharnai, India—provide exciting models for other cities and towns around the world that are beginning to make the transition to clean energy.

22 Powerful Closure Activities

22 Powerful Closure Activities
DECEMBER 15, 2015
4.7KSHARES

Photo credit: Stephen Luke via flickr (CC BY 2.0)
Too many university supervisors and administrators criticize the absence of lesson closure, a dubious assessment practice likely caused by the improper use of Madeline Hunter’s lesson plan model (PDF) as a de facto checklist of eight mandatory teaching practices -- anticipatory set, objective and purpose, input, modeling, checking for understanding, guided practice, independent practice, and closure -- a custom that Hunter decried in 1985 (PDF). Although it offers multiple benefits, please don't view closure as a professional must-do.

What Is Closure?
Closure is the activity that ends a lesson and creates a lasting impression, a phenomenon that Colorado State University professor Rod Lucero calls the recency effect.

Teachers use closure to:

Check for understanding and inform subsequent instruction
Emphasize key information
Tie up loose ends
Correct misunderstandings
Students find closure helpful for:

Summarizing, reviewing, and demonstrating their understanding of major points
Consolidating and internalizing key information
Linking lesson ideas to a conceptual framework and/or previously-learned knowledge
Transferring ideas to new situations
Like contracting your bicep at the top of a dumbbell curl, closure squeezes an extra oomph into a lesson. See my favorite closure strategies below!

Creative Closure Activities
1. Snowstorm
Students write down what they learned on a piece of scratch paper and wad it up. Given a signal, they throw their paper snowballs in the air. Then each learner picks up a nearby response and reads it aloud.

2. High-Five Hustle
Ask students to stand up, raise their hands and high-five a peer -- their short-term hustle buddy. When there are no hands left, ask a question for them to discuss. Solicit answers. Then play "Do the Hustle" as a signal for them to raise their hands and high-five a different partner for the next question. (Source: Gretchen Bridgers)

3. Parent Hotline
Give students an interesting question about the lesson without further discussion. Email their guardians the answer so that the topic can be discussed over dinner.

4. Two-Dollar Summary
Kids write a two-dollar (or more) summary of the lesson. Each word is worth ten cents. For extra scaffolding, ask students to include specific words in their statement. (Source (PDF): Ann Lewis and Aleta Thompson)

5. Paper Slide
On paper, small groups sketch and write what they learned. Then team representatives line up and, one and a time, slide their work under a video camera while quickly summarizing what was learned. The camera doesn't stop recording until each representative has completed his or her summary.

6. DJ Summary
Learners write what they learned in the form of a favorite song. Offer extra praise if they sing.

7. Gallery Walk
On chart paper, small groups of students write and draw what they learned. After the completed works are attached to the classroom walls, others students affix Stickies to the posters to extend on the ideas, add questions, or offer praise.

8. Sequence It
Students can quickly create timelines with Timetoast to represent the sequence of a plot or historical events.

9. Low-Stakes Quizzes
Give a short quiz using technologies like Socrative, BubbleSheet, GoSoapBox, or Google Forms. Alternatively, have students write down three quiz questions (to ask at the beginning of the next class).

10. Cover It
Have kids sketch a book cover. The title is the class topic. The author is the student. A short celebrity endorsement or blurb should summarize and articulate the lesson's benefits.

11. Question Stems
Have students write questions about the lesson on cards, using question stems framed around Bloom's Taxonomy. Have students exchange cards and answer the question they have acquired.

12. So What?
Kids answer the following prompts:

What takeaways from the lesson will be important to know three years from now?
Why?
13. Dramatize It
Have students dramatize a real-life application of a skill.

14. Beat the Clock
Ask a question. Give students ten seconds to confer with peers before you call on a random student to answer. Repeat.

15. Find a First-Grade Student
Have kids orally describe a concept, procedure, or skill in terms so simple that a child in first grade would get it.

16. Review It
Direct kids to raise their hands if they can answer your questions. Classmates agree (thumbs up) or disagree (thumbs down) with the response.

17. CliffsNotes, Jr.
Have kids create a cheat sheet of information that would be useful for a quiz on the day's topic. (Source (PDF): Ann Sipe, "40 Ways to Leave a Lesson")

18. Students I Learned From the Most
Kids write notes to peers describing what they learned from them during class discussions.

19. Elevator Pitch
Ask students to summarize the main idea in under 60 seconds to another student acting as a well-known personality who works in your discipline. After summarizing, students should identify why the famous person might find the idea significant.

20. Simile Me
Have students complete the following sentence: "The [concept, skill, word] is like _______ because _______."

21. Exit Ticket Folder
Ask students to write their name, what they learned, and any lingering questions on a blank card or "ticket." Before they leave class, direct them to deposit their exit tickets in a folder or bin labeled either "Got It," "More Practice, Please," or "I Need Some Help!" -- whichever label best represents their relationship to the day's content. (Source: Erika Savage)

22. Out-the-Door Activity
After writing down the learning outcome, ask students to take a card, circle one of the following options, and return the card to you before they leave:

Stop (I'm totally confused.)
Go (I'm ready to move on.)
Proceed with caution (I could use some clarification on . . .)
Download the PDF cards for this exercise. (Source: Eduscapes)

These 22 strategies can be effectively altered or blended. And they are great opportunities to correct, clarify, and celebrate.

Do you use a closure activity that's not on this list? Please share it in the comments.
