"Teaching climate science & action can seem daunting: for university-level lecturers, teaching to younger children can be quite intimidating. For primary-level teachers, the science and scope can seem too vast and fast changing to cover. For everyone, the content can be overwhelming. As adults, how do we present this topic to children: give them the information they need without crushing them? I decided to face the challenge, and over the course of one rather sleepless night, put together some materials for my 6 year-old son's class. This post summarizes and communicates that experience, in the hope that others can take ideas and inspiration, and will be encouraged to volunteer to teach about climate in primary schools. Teaching and engagement in schools is now part of all of our work, as researchers, academics, parents, activists, advocates, so I hope this idea spreads. The 4-part lesson plan worked quite well: the topics & materials held the children's attention, gave them varied aspects to think about and interact with, and they seemed to come away with deeper understanding. The whole thing took roughly 1 hour. This is doable!"

"Today, getting what you need is as easy as a trip to the store. From food to clothing, energy, medicine, and so much more, Andy George will discover what it takes to make everything from scratch. His mission is to understand the complex processes of manufacturing that is often taken for granted and do it all himself. Each week he's traveling the world to bypass the modern supply chain in order to harvest raw materials straight from the source. Along the way, he's answering the questions you never thought to ask."

"Our new blog is designed to radically reduce the energy use associated with accessing our content. Low-tech Magazine was born in 2007 and has seen minimal changes ever since. Because a website redesign was long overdue - and because we try to practice what we preach - we decided to build a low-tech, self-hosted, and solar-powered version of Low-tech Magazine. The new blog is designed to radically reduce the energy use associated with accessing our content. Why a Low-tech Website? We were told that the Internet would "dematerialise" society and decrease energy use. Contrary to this projection, it has become a large and rapidly growing consumer of energy itself. In order to offset the negative consequences associated with high energy consumption, renewable energy has been proposed as a means to lower emissions from powering data centers. For example, Greenpeace's yearly ClickClean report ranks major Internet companies based on their use of renewable power sources."

"MapMap is a free, open source software for projection mapping aimed at artists and small teams. Its intuitive interface facilitates learning and promotes artistic expression. This software is available on Windows, OSX, and Linux. MapMap gives users the ability to projection map on any surface of choice. Mapmap takes media sources and gives users the ability to manipulate the media into different positions and shapes. Media sources can come from any various accepted media formats. With an easy to understand interface, new users can get started in minutes. Projection mapping, also known as video mapping and spatial augmented reality, is a projection technology used to turn objects, often irregularly shaped, into a display surface for video projection. These objects may be complex industrial landscapes, such as buildings. By using specialized software, a two or three dimensional object is spatially mapped on the virtual program which mimics the real environment it is to be projected on. The software can interact with a projector to fit any desired image onto the surface of that object. This technique is used by artists and advertisers alike who can add extra dimensions, optical illusions, and notions of movement onto previously static objects. The video is commonly combined with, or triggered by, audio to create an audio-visual narrative."

"A webinar can take many forms, such as a meeting, presentation, or workshop. The main difference between running a webinar and simply posting a video is the interactive component the former offers. Attendees typically view webinars in real time, and there is often the option for them to participate by asking and/or answering questions. This type of seminar offers an excellent opportunity to add a personal touch to your platform and engage your customers. For example, Neil Patel uses webinars frequently to reach out to visitors of his traffic growing website. Step #1: Create a Google Account Step #2: Create a New Event in YouTube Live Step #3: Customize Your Webinar Step #4: Embed Your Webinar in Your WordPress Website Step #5: Invite Attendees Step #6: Broadcast Your Webinar"

"New scientific research is quietly rewriting the fundamentals of economics. The new economic science shows decisively that the age of endlessly growing industrial capitalism, premised on abundant fossil fuel supplies, is over. The long-decline of capitalism-as-we-know-it, the new science shows, began some decades ago, and is on track to accelerate well before the end of the 21st century. With capitalism-as-we-know it in inexorable decline, the urgent task ahead is to rewrite economics to fit the real-world: and, accordingly, to redesign our concepts of value and prosperity, precisely to rebuild our societies with a view of adapting to this extraordinary age of transition."

"Hardly anyone seems to have noticed that the newest climate science suggests we are about to pass the point of no return, to unstoppable, catastrophic global warming. This short animation explains the positive feedback mechanisms that mean the Earth's climate system has a tipping point, followed by a brief glimpse into the crystal ball of horrors that will almost certainly come to pass if we cross it. Finally, the film explores how we got into the mess we're in, and the possibilities still open to us to prevent the worst natural and humanitarian disaster in human history, and the very real possibility of the end of civilization, and of life as we know it."

"CoRubrics, an add-on for Google Sheets helps teachers in the assessment process. It is used to assess students (or groups of students) with a rubric designed by the teacher and also allows students to assess other students (coevaluation). CoRubrics automates the entire process. First, teachers design the rubric they want to use in Google Sheets, then they add the students' names and their email address. (These can be imported from Google Classroom). Once this is done, the add-on will: Create a Google Form with the contents of the rubric. Send the form to the students by email or simply provide the link to the teacher. Process the data once the form is filled out (by the students or by the teacher). Finally, send the results to the students (each student receives only their results) with a personalized comment. In addition, CoRubrics allows: Insert comments when answered. Allow Co-evaluation, self-assessment and teacher assessment with one link."

"France plans to outlaw the destruction of unsold consumer products, a practice that currently results in the disposal of new goods worth 800 million euros, or more than $900 million, in the country each year. By 2023, manufacturers and retailers will have to donate, reuse or recycle the goods, Prime Minister Édouard Philippe said on Tuesday of the measure, which the government billed as the first of its kind. "It is waste that defies reason," Mr. Philippe said at a discount store in Paris, according to Agence France-Presse, and he called the practice "scandalous." Under a new measure that will be part of a bill set to be debated by the government in July, destroying unsold goods could result in financial penalties or prison time. The practice - widespread across the retail and consumer industry as a way to free up warehouse space or prevent unwanted items from being sold at a significant discount - has received bad press in France recently. ..."

"With little water, scorching temperatures, and not much arable land, the UAE currently imports 80% of its food. Can it go local? In an industrial park built off a highway in the arid land between Abu Dhabi and Dubai, a sprawling new indoor farm will soon grow tomatoes under LED lights in a climate-controlled warehouse near a plastic production facility and other factories. The farm, the first in the world to commercially grow tomatoes solely under artificial light, is one part of a push to transform food production in the United Arab Emirates, where 80% of food is imported. The government realizes that to be resilient, it will need to find new ways to grow food in a desert climate with little rain and temperatures that regularly stay above 100 degrees."

"Back in the 1980s, a group of social workers in Jamaica visited low-income homes one hour a week for two years, bearing age-appropriate toys for the kids and advice on child rearing for the parents. Researchers tracked the outcomes, and a generation later, the results are in. The children whose homes were visited by social workers became adults who earn wages that are 25 percent higher than those earned by peers who had not been visited. Their I.Q.s are an average seven points higher, and they are less likely to resort to crime or suffer from depression. Other studies, including several recent ones in the United States, have shown similar results, contributing to a consensus on the importance of early childhood development that has led governments around the world to increase spending on the first five years of life. In Latin America and the Caribbean, a region of longstanding social and economic inequality, several countries have been especially ambitious. Brazil and Chile doubled the coverage of day care services over the past decade, while in Ecuador they grew sixfold. These investments build on historic gains in child nutrition and health. But while Latin American children are now healthier and more likely to attend preschool, they still lag far behind in learning, particularly in the areas of language and cognition, when compared with their counterparts in wealthy countries. What are we doing wrong? ..."

"A state-of-the-art supercomputer simulation indicates that a feedback loop between global warming and cloud loss can push Earth's climate past a disastrous tipping point in as little as a century. On a 1987 voyage to the Antarctic, the paleoceanographer James Kennett and his crew dropped anchor in the Weddell Sea, drilled into the seabed, and extracted a vertical cylinder of sediment. In an inch-thick layer of plankton fossils and other detritus buried more than 500 feet deep, they found a disturbing clue about the planet's past that could spell disaster for the future. Lower in the sediment core, fossils abounded from 60 plankton species. But in that thin cross-section from about 56 million years ago, the number of species dropped to 17. And the planktons' oxygen and carbon isotope compositions had dramatically changed. Kennett and his student Lowell Stott deduced from the anomalous isotopes that carbon dioxide had flooded the air, causing the ocean to rapidly acidify and heat up, in a process similar to what we are seeing today."

"In order to help reduce the gap between industrialized countries and those in the emerging economy, UNESCO has decided to adopt an Open Access Policy for its publications by making use of a new dimension of knowledge sharing - Open Access. Open Access means free access to scientific information and unrestricted use of electronic data for everyone. With Open Access, expensive prices and copyrights will no longer be obstacles to the dissemination of knowledge. Everyone is free to add information, modify contents, translate texts into other languages, and disseminate an entire electronic publication."

"Our core ecological problem is not climate change. It is overshoot, of which global warming is a symptom. Overshoot is a systemic issue. Over the past century-and-a-half, enormous amounts of cheap energy from fossil fuels enabled the rapid growth of resource extraction, manufacturing, and consumption; and these in turn led to population increase, pollution, and loss of natural habitat and hence biodiversity. The human system expanded dramatically, overshooting Earth's long-term carrying capacity for humans while upsetting the ecological systems we depend on for our survival. Until we understand and address this systemic imbalance, symptomatic treatment (doing what we can to reverse pollution dilemmas like climate change, trying to save threatened species, and hoping to feed a burgeoning population with genetically modified crops) will constitute an endlessly frustrating round of stopgap measures that are ultimately destined to fail."

"When you pick your tomatoes, if you want to keep them longer, you have to find a way of reducing the temperature. As availability of electricity at village level can be a problem, ways have to be found to lower the temperature of this fragile crop. Some farmers at Dambatta in Kano State, Nigeria have used local mud bricks to make a very effective cooling chamber."

"My name is Asray and I am a 15 year old who has a keen love of making projects out of cardboard. Today I will show you all how to make a 3D Labyrinth Maze made out of cardboard.This project is simple to make and super fun to play with. Traditionally, mazes are 2D and super boring to play with but I made a maze with a twist so that it is challenging and fun to play with."

Las 3 reglas de @ramusallam: 1 la curiosidad va primero 2 aceptar el desastre 3 practicar la reflexión "It took a life-threatening condition to jolt chemistry teacher Ramsey Musallam out of ten years of "pseudo-teaching" to understand the true role of the educator: to cultivate curiosity. In a fun and personal talk, Musallam gives 3 rules to spark imagination and learning, and get students excited about how the world works. "

"The transition from unicellular to multicellular life was one of a few major events in the history of life that created new opportunities for more complex biological systems to evolve. Predation is hypothesized as one selective pressure that may have driven the evolution of multicellularity. Here we show that de novo origins of simple multicellularity can evolve in response to predation. We subjected outcrossed populations of the unicellular green alga Chlamydomonas reinhardtii to selection by the filter-feeding predator Paramecium tetraurelia. Two of five experimental populations evolved multicellular structures not observed in unselected control populations within ~750 asexual generations. Considerable variation exists in the evolved multicellular life cycles, with both cell number and propagule size varying among isolates. Survival assays show that evolved multicellular traits provide effective protection against predation. These results support the hypothesis that selection imposed by predators may have played a role in some origins of multicellularity."
