Ceux qui dénoncent le clip de prévention produit par l'Éducation nationale, jugé «caricatural et méprisant», sont hors sujet. C'est l'histoire d'un rapt. Le 2 novembre, le ministère de l'Education nationale a rendu public le clip de prévention contre le harcèlement scolaire coproduit par Mélissa Theuriau. Presque aussitôt, des profs (et non pas «les profs», comme on l'a lu et entendu) ont manifesté leur mécontentement en dénonçant une «vidéo caricaturale et méprisante». Ils ont surtout, à gros coups de communiqués rageurs publiés par des syndicats pourtant souvent désaccordés, réussi à détourner les projecteurs du sujet principal (la souffrance des enfants harcelés) pour les braquer vers leur propre cause: le supplice enduré par des enseignants se sentant stigmatisés par une vidéo d'une minute qui ne s'adresse même pas à eux. C'est le premier problème de cette réaction. Allégorie Ce que semblent avoir oublié les profs qui s’insurgent contre ce spot, c’est son caractère allégorique.
Les enseignants ont kidnappé le débat sur le harcèlement à l'école
A few months ago, my four year-old son went to a classmate's birthday. The party was superhero-themed and the loot bags were packed with cute little superhero trinkets, including temporary tattoos. One little girl, let's call her Izzy, put hers on immediately. "LOOK," Izzy yelled, running up to everyone in turn. The other children and parents in attendance oohed and ahed over her forearm. Later, as we parents were watching our cake-smeared kids run around in a sugar-induced frenzy, one of the other mothers turned to me and said, "Isn't it funny that [your son] loves My Little Pony so much? Not really knowing how to answer, I said, "I don't think it's funny. "Oh, sure," she said. I've been thinking a lot about this episode, along with all the other weird remarks people have made about my kid's love for all things Rainbow Dash. Little girls are, for the most part, taught that women can be anything. We see the devaluation of femininity play out in tons of different ways.

Bon, une fois n’est pas coutume, cet article-là, je l’écris surtout avec mes tripes (et en le démarrant je ne sais pas exactement où je vais avec). D’ailleurs ça introduit bien le sujet. D’habitude justement, je rédige mes articles un peu comme des dissertations. Avec un plan (construit à partir d’une liste d’idées) dans la tête, des parties, des sous-partes, des transitions, une intro, une conclusion. Il faut dire que des disserts et des commentaires, comme plein de gens, j’en ai fait depuis mes 15 ans jusqu’à la fin de ma licence. C’est devenu naturel chez moi d’écrire comme ça. D’ailleurs, j’ai souvent été considéré comme un intello, dans ma scolarité. Évidemment, le côté « intello » n’aide pas pour éviter le harcèlement, la mise à l’écart et l’effet plante verte. Et pourtant, au collège comme au lycée, je ne faisais pas réellement partie des bons élèves. C’était une erreur, parce que j’ai (évidemment) continué à ramer dans les matières scientifiques.

This gyroscope remains upright while spinning due to the conservation of its angular momentum. In physics, angular momentum, (rarely, moment of momentum or rotational momentum) is the rotational analog of linear momentum. It is an important quantity in physics because it is a conserved quantity – the angular momentum of a system remains constant unless acted on by an external torque. Angular momentum in classical mechanics Definition Scalar - angular momentum in two dimensions Velocity of the particlem with respect to the origin O can be resolved into components parallel to (v//) and perpendicular to (v⊥) the radius vector r. and linear speed angular momentum is proportional to moment of inertia and angular speed Unlike mass, which depends only on amount of matter, moment of inertia is also dependent on the position of the axis of rotation and the shape of the matter. Because for a single particle and for circular motion, angular momentum can be expanded, and reduced to, , where
Thundarr the Barbarian is a Saturday morning animated television series, created by Steve Gerber and produced by Ruby-Spears Productions. The series ran 2 seasons, 1980–1981 and 1981–1982. Action figures of the three main characters were released by Toynami in 2004. Production Twenty-one half-hour episodes were produced by Ruby-Spears Productions, an animation house formed by former Hanna-Barbera head writers Joe Ruby and Ken Spears, from October 1980 to September 1982, when the show went off the air. Plot Further Star Wars influences can be seen in Thundarr's weapon of choice, the Sunsword, which projects a blade-like beam of energy when activated, and can be deactivated so that it is only a hilt. Comic book writer-artist Jack Kirby worked on the production design for the show. Opening narration The year: 1994.

Dr. Winston Roberts, The Quark Model
The Quark Model Once the quark model was proposed to explain all of the 'elementary particles' that were being observed in the fifties and sixties, it was realized that sets of the new particles could be grouped together in a particular way, if there were three kinds of quarks, three flavors, that made up these particles. This way of grouping the particles together, or classification scheme, was called 'The Eightfold Way' by one of its early proponents, Dr. Murray Gell-Mann. It is a mathematical scheme derived from group theory (no, not group therapy). At the time a number of mesons had been discovered, and from they way in which they disintegrated or decayed (the particles found lived for very short times, often less than a microsecond), the quarks that they contained could be deduced. In going across the diagram from left to right, a down quark is replaced by an up quark, or an up antiquark is replaced by a down antiquark. All content © Winston Roberts 2006
Does it seem odd to be thinking about raising an active child when your baby hasn’t been born yet or can’t even roll over on her own? As a new parent or new parent-to-be there’s a lot to think about and physical activity might seem like something that you can postpone focusing on about for at least a few more years. In the first year of life, your infant learns simple motor coordination skills that are essential to all aspects of her cognitive, emotional, and physical development. It’s a lot like setting the stage for a love of language and reading. So how can you give your child the best start? From our experts: From our role models:

The Teaching Games for Understanding (TGfU) approach was developed by researchers at Loughborough University in the United Kingdom to tap into children’s inherent desire to play. Bunker and Thorpe (1982) developed TGfU around the concept of teaching kids games by playing games. Butler et al. (2008) identified six Basic TGfU Concepts: Teach games through games.Break games into their simplest format - then increase complexity.Participants are intelligent performers in games.Every learner is important and is involved.Participants need to know the subject matter.Need to match participants’ skill and challenge. Recent approaches to TGfU have advocated for a thematic approach to teaching games. These categories represent games and activities that are similar in structure. The skills and strategies used in the PlaySport activities are applicable to several different sports.

Over-protective parents doing harm to their kids, speaker tells Sport Aurora summit
While many are quick to point a finger of blame at cellphones and video games for children’s sedentary lifestyles, one expert suggests adults should first take a long look in the mirror. Drew Mitchell, physical literacy director for Canadian Sport for Life, addressed a crowd gathered at Seneca College in King last week during a physical literacy summit hosted by Sport Aurora. The audience represented stakeholders encompassing education, health, business, government and the sport-minded folks eager to discover the definition and practical applications of physical literacy. “Kids want to move. “Adults have become the barrier to activity.” Every day, children and adults are glued to screens and whether it be a cellphone, computer, tablet or TV, inactivity isn’t a physiological issue, it’s a behavioural issue, Mitchell added. What physical literacy means: It’s having the motivation, confidence, physical competence, knowledge and understanding to value and take responsibility for engagement.
This Robot Could Make Exploring Oceans Deeper, Faster, and Cheaper
Wendy Schmidt couldn't contain her grin as she watched the robot rise from the bottom of the saltwater tank at the Monterey Bay Aquarium Research Institute in Moss Landing, California. It was the first test run of SuBastian, her custom-built remotely operated vehicle (ROV). The underwater robot belonged to the Schmidt Ocean Institute (SOI), a nonprofit organization that Schmidt co-founded with her husband, Eric, executive chairman of Alphabet, Inc. (the parent company of Google). The Schmidts created SOI in 2009 to speed up communication of marine research among scientists and the public, after they discovered that scientists were faced with too many unknowns about the ocean—thus making it harder to protect. As part of that mission, the couple launched a project to build an unmanned robot that would inspire innovation in machine design, be created entirely around scientists' needs, and be ready to test in about a year—a tough request on all fronts.
The soaring temperature of the oceans is the “greatest hidden challenge of our generation” that is altering the make-up of marine species, shrinking fishing areas and starting to spread disease to humans, according to the most comprehensive analysis yet of ocean warming. The oceans have already sucked up an enormous amount of heat due to escalating greenhouse gas emissions, affecting marine species from microbes to whales, according to an International Union for Conservation of Nature (IUCN) report involving the work of 80 scientists from a dozen countries. The profound changes underway in the oceans are starting to impact people, the report states. “Due to a domino effect, key human sectors are at threat, especially fisheries, aquaculture, coastal risk management, health and coastal tourism.” Dan Laffoley, IUCN marine adviser and one of the report’s lead authors, said: “What we are seeing now is running well ahead of what we can cope with.

Image copyright Ittiz The next ice age may have been delayed by over 50,000 years because of the greenhouse gases put in the atmosphere by humans, scientists in Germany say. They analysed the trigger conditions for a glaciation, like the one that gripped Earth over 12,000 years ago. The shape of the planet's orbit around the Sun would be conducive now, they find, but the amount of carbon dioxide currently in the air is far too high. Earth is set for a prolonged warm phase, they tell the journal Nature. "In theory, the next ice age could be even further into the future, but there is no real practical importance in discussing whether it starts in 50,000 or 100,000 years from now," Andrey Ganopolski from the Potsdam Institute for Climate Impact Research said. "The important thing is that it is an illustration that we have a geological power now. Earth has been through a cycle of ice ages and warm periods over the past 2.5 million years, referred to as the Quaternary Period. Planet rock

One of the most amazing highlights of my trip to Dubai was the opportunity to fly in a hot air balloon with Balloon Adventures Emirates. It was incredible! The hot air balloon ride is the inspiration behind The Hot Air, Cold Air Science Activity. There is so much science behind the idea of hot air balloons and I thought that sharing the photos with my children of the balloon ride would be a great opportunity to extend this learning into a science activity. This Hot Air, Cold Air Science Activity is a great experiment to watch the effects of hot air and cold air on a balloon. This activity is a great opportunity for kids to talk about what they can see and why it is happening. What you will need? You will need two containers, one filled with hot tap water and the other with ice and cold water. Please do not use boiling hot water for this activity. Let’s Play During the following steps of the activity, provide children with the opportunity to predict, ask questions and discuss ideas.

Investigating Condensation and the Water Cycle
Step-by-step Lesson and Free Printables Most kids are familiar with the terms precipitation, condensation, and evaporation, but very few of them really understand what those words mean. Just ask your students to name three examples of condensation in everyday life and watch their eyes glaze over. Most kids understand that precipitation is a fancy word for different forms of water falling from the sky, like rain, snow, and sleet. Condensation is a little harder to grasp. Condensation Investigation Here's a simple investigation that will help your students understand what condensation is, where it comes from, and where it happens in everyday life. Condensation Investigation is designed for students working in teams, but it's a teacher-directed exploration rather than an independent group activity. Advance Preparation Before using the activity with your students, gather the materials described on the Condensation Investigation handout, and try the activity yourself. Testing the Hypothesis
