The Energy Story - Chapter 1: Energy - What Is It? Energy causes things to happen around us. Look out the window. During the day, the sun gives out light and heat energy. At night, street lamps use electrical energy to light our way. When a car drives by, it is being powered by gasoline, a type of stored energy. The food we eat contains energy. We learned the definition of energy in the introduction: "Energy Is the Ability to Do Work." Energy can be found in a number of different forms. Stored and Moving Energy Energy makes everything happen and can be divided into two types: Stored energy is called potential energy. With a pencil, try this example to know the two types of energy. Put the pencil at the edge of the desk and push it off to the floor. Now, pick up the pencil and put it back on the desk. How Do We Measure Energy? Energy is measured in many ways. One of the basic measuring blocks is called a Btu. Btu is the amount of heat energy it takes to raise the temperature of one pound of water by one degree Fahrenheit, at sea level. 1.

The Franklin Institute - Exhibit - Electricity Feel the force of electricity by manipulating electrical phenomena, exploring authentic artifacts, and tackling questions of sustainable electricity generation and use. This exhibition is energized, with interactive devices and graphics glowing from within the darkened gallery, illustrated by simple, edgy imagery. At its foundation, electricity is derived from the interaction of charges. Electricity will spark your curiosity about the power of this phenomenon and what it holds for our future. Antique Lightning Rods The Electricity exhibit is now home to an intriguing collection of eight artfully-handcrafted antique lightning rods, dating from the late 18th through mid-20th centuries. The featured centerpiece of Electricity is a Sustainable Dance Floor, which generates power to illuminate itself as people move on the tiles. To delve into Benjamin Franklin's pioneering studies, visitors browse through an electronic copy of his book Experiments and Observations on Electricity.
Fröken Ann | "Beneath this mask there is more than flesh. Beneath this mask t... How Electricity Works" Humans have an intimate relationship with electricity, to the point that it's virtually impossible to separate your life from it. Sure, you can flee from the world of crisscrossing power lines and live your life completely off the grid, but even at the loneliest corners of the world, electricity exists. If it's not lighting up the storm clouds overhead or crackling in a static spark at your fingertips, then it's moving through the human nervous system, animating the brain's will in every flourish, breath and unthinking heartbeat. When the same mysterious force energizes a loved one's touch, a stroke of lightning and a George Foreman Grill, a curious duality ensues: We take electricity for granted one second and gawk at its power the next. Electricity powers our world and our bodies. In this article, we'll try to provide a less slippery answer.
Jesper Juul om respekt, relationer och vikten av olydnad att debatten om skolan handlar om fel saker. Vi fokuserar på struktur och om det ska vara fler undervisningstimmar i matematik eller språk. Men det vi egentligen borde lägga kraft på är att utveckla lärarnas relationella kompetens. – Det bästa vi kan göra är att använda tio år till att skämma bort lärarna. Och det vi ska skämma bort dem med är vidareutbildning. Han räknar upp fyra teman som många lärare har problem med: Det är deras förmåga till meningsfull dialog med enskilda barn, meningsfull dialog med grupper av barn, meningsfull dialog med föräldrar – och ledarskapet. Men, säger han. – Man kan inte säga till en pizzakock på en take away-servering att han helt plötsligt ska börja jobba på en restaurang med tre stjärnor i Guide Michelin! Jesper Juul är kanske mest känd som författare till bästsäljaren Ditt kompetenta barn och som ihärdig motståndare till manualer och metoder i föräldraskap och uppfostran. – Stat och kommun har precis så mycket ansvar som föräldrarna har.
Kids Zone: Our Electricity What is electricity? Where does it come from? Who discovered it? When is it dangerous? Did you know? GoEd Online (via GoEd Online) 11 Things to Know About Using Khan Academy I first saw mention of the Khan Academy while reading a post by Brad Evans, who sifts through 50 educational technology tools. When I saw the Khan Academy on there and read his description of it—a collection of over 3,500 videos that teach students many topics across the science and math disciplines—I thought, “Wow, I wish I would have had this when I was a student!” I was never good at science and these videos would have definitely helped. The Khan Academy is, quite simply, a non-profit company whose mission is to create a bank of educational videos, specifically in the math and science realms, in order to teach, challenge, and assess students. How many of your students have a tough time with math, science, or both?
