Geothermal Education Office "Geothermal" comes from the Greek words geo (earth) and therme (heat). So, geothermal means earth heat. Our earth's interior - like the sun - provides heat energy from nature. This heat - geothermal energy - yields warmth and power that we can use without polluting the environment. The heat from the earth's core continuously flows outward. From earliest times, people have used geothermal water that flowed freely from the earth's surface as hot springs. Today we drill wells into the geothermal reservoirs to bring the hot water to the surface. In geothermal power plants steam, heat or hot water from geothermal reservoirs provides the force that spins the turbine generators and produces electricity. Clean. Since the first geothermally-generated electricity in the world was produced at Larderello, Italy, in 1904 the use of geothermal energy for electricity has grown worldwide to about 7,000 megawatts in twenty-one countries around the world.
Curiosity Cabinet Over the past 25 years I have accumulated a collection of various gizmos, devices, toys etc. which to me are excellent examples of scientific principles or things that you look at and you say "That's impossible!" except it's staring you in the face. In the hope that others may also find them interesting and with the help of two undergraduates, Jacy Lundberg and Omar Khan, we have created videos of many of the items in the collection. Jacy and Omar are currently seniors in the Boston College pre-medical program. In the olden days some people assembled what were known as curiosity cabinets.
The Physics Classroom A Once (or Twice) in a Lifetime Syzygy | Hello. My name is Howard. Kristen is my other half. It was nearly seven years ago Kristen suggested we see a planetarium show. A simple definition of a syzygy (si-zə-jē) is a straight line configuration of three celestial bodies, within a gravitational system. This image shows how the Sun, Venus and the Earth will line up on June 5, 2012. On June 4th, 2012 the Moon will pass partially through the Umbral shadow of Earth. There are at least two lunar eclipses a year. OK. An astronomical transit occurs when one celestial body appears to move across the face of another celestial body, from the vantage point of another celestial body. This image taken June 8, 2004 shows the apparent size of Venus against the disk of the Sun. For those of us on the side of Earth that will be facing the Sun, we get to see something that occurs cyclically every 243 years. The first half of this century’s pair of transits occurred on June 8, 2004. There are several ways to observe the transit.

World Biomes Pin Map | The Homeschool Den June 12, 2012 at 5:20 am , by Liesl Den Are you asking yourself, “What in the world is a biomes pin map?” It’s a map that shows where the rain forests, deserts, grasslands, forest and tundra regions are located. Before we really delved into our study of rain forest foods (and chocolate!) First, we reviewed the seven continents song for ED (to the tune of Frère Jacques) : Europe, Asia, A-fri-ca-a North America, South America Then there is Antarctica Don’t forget Australia Seven continents, Seven Continents Then I had the kids guess what the colors were on the map (because it’s been a couple of years since we used this map). We talked about the different biomes in North America and placed those pins onto the map. We then pulled out the Rain Forest pins and talked about the regions of the world that are covered with rain forests. If you are interested in making your own world biomes pin map here are the printables: World Biome Map (used with permission) Pin Map Pieces Page 1
PhysicsLAB: Converging Lenses Any lens that is "thicker in the center" than on the edges is generally described as a convex lens and will function as a converging lens when it is operating in air. The point where all rays which enter the lens parallel to its axis are brought to a focus is called the principal focus. This position is located behind the lens and is usually labeled as F in ray diagrams. Whenever the actual rays of light that refract through the lens converge behind the lens to form an image, that type of image is called a real image. Since the actual rays of light passing through the lens form these real images, they are also known as "hot" images. Converging Lenses There are three primary rays which are used to locate the images formed by converging lenses. Remember, ALL rays must have ARROWS! When the physlet opens notice that the author has listed for you the initial focal length, object distance and image distance.
Welcome to a Resource for Physics Teachers | Physics & Physical Science Demos, Labs, & Projects for High School Teachers This site is designed to help physics teachers share their ideas. Many of us are the sole physics teacher in their school. It’s nice to know there are others out there to help develop experiments and demonstrations. I will be listing many of my demos and activities along with a commentary on what works and what doesn’t. The school I teach in is new. 2006/2007 was the first year there was a 12th grade. I’m looking for contributors, even if it’s one or two postings. – Scott Like this: Like Loading... Where We Work Page Content We know that there are more species in tropical regions and that undiscovered species are likely to be found in places that have been off-limits to exploration or that are very difficult to access. So in order to discover large numbers of species potentially new to science, we head to countries with poorly explored, remote, humid tropical mountains. In addition, unique not-yet-described species are likely to be found in habitats that require special adaptations to survive, such as areas with low oxygen levels (e.g. swamps) and limestone caves. To identify the best sites to explore, we start with consultations with expert scientists, who generally know which places have been explored and where the gaps in data are. We also carry out scientific priority-setting analyses, putting together the data we currently have on species diversity with factors that affect their distribution, such as the types of habitats where species discoveries have been made.

prettygoodphysics - home You'll Flip Over Forces & Motion Submitted by Heidi BaitzLudlow Elementary SchoolLudlow, Vermont 05149baitzh@ludlowelementary.org Digital Wish Grant Does Your Classroom Flip? “We are Newtonians, fervent and devout, when we speak of forces and masses, of action and reaction; when we say that a sports team has momentum, when we note the inertia of a tradition or bureaucracy; and when we stretch out an arm and feel the force of gravity all around, pulling earthward.” James Gleick Overview:This intensive course, designed specifically for K-8 teachers, will focus on forces and motion as understood through Newton’s Laws of Motion. Conceptual and quantitative understanding plus applications to many areas of our lives will be emphasized through inquiry, learning cycles, and the use of science notebooks. Goal:This past summer while co-teaching a course on “Forces and Motion” at Castleton State College, my partner, Dr. Forces & Motion Scavenger Hunt Using your flip camera ... 1. 2. 3. 4. 5. 6. 7. 8. 9. 10.
Gas station without pumps Physics homework chapter 12 Chapter 12 of Matter and Interactions is entropy and temperature. I’ve not come up with any labs I really want us to do for Chapter 12, and with class cancelled next week (June 15) I’m not sure when we’ll get to do an entropy lab. The only lab I’ve thought of is to build an electric calorimeter and measure the specific heat of water, but that sounds like more effort than it is worth. The microwave and styrofoam cup exercise in 12.P.45 doesn’t seem much better than just looking up the specific heat of water. I would like us to continue on the rocket experiment, now that the simulation seems to be working. Anyway, Chapter 12 homework, which we’ll try to have at least half done by Fri June 8, our next meeting: 12.P.40, 12.P.43, 12.P.48, 12.P.62, 12.P.63, 12.P.66, 12.P.68. Like this: Like Loading...

New content for HyperPhysics will be posted as it is developed. A resource that was initiated as a resource for local high school physics teachers whom I had taught has expanded into an intensively used website worldwide. CD or DVD versions have been sent to 86 countries to date, and translations into German, Italian, Chinese, and Español have been licensed and are underway.
