Energy

For my project I asked the question, “How do you measure light intensity?” Below are pictures of a photometer; it is used to measure light intensity. For instructions on how to make the photometer, click [|here]. For my experiment I compared a 60 watt bulb to a 100 watt bulb. After using the photometer to measure which wattage was giving off more light, I came up with the conclusion that the 100 watt bulb gives off almost double the light of the 60 watt. This was a really interesting project, I learned a lot!!!!!

media type="custom" key="3598962" For my project I was trying to answer the question " Is it possible to reduce your carbon footprint and is it economical ". Originally I was going to create a model of the perfect carbon neutral house on DSS Solidworks, but I was limited in time and decided to create the house on Google Sketchup. My house is designed to us solar panels on the left roof teir, the right roof teir is for green space. The house is designed with a "sawtooth style" roof to let in nautral light so less electricity is needed for lighting. It has a gray water system as well. My house has triple pane windows to insulate well. it is a 936 square foot house, so it would be a serious downsize for most middle class families. The house it self lowers your carbon footprint not much. Here is a picture of my house. Also there are a few cars that I decided to test as well. The cars I decided to test were: the Toyota Prius (winner), the Honda Fit (runner-up), and the Smart Fortwo (third). The Smart Fortwo is not very efficient in it's gas version (comparitivly), but the diesel version only available in Europe gets around 65-70 MPG. If you decided to use the Toyota Prius as your main car, you would reduce your carbon footprint a larger amount than the house, but still not much. My final stats are: -Without Carbon Footprint Reduction -9.36 tonnes total of CO² -5 tonnes for house -4 tonnes for car -.36 tonnes for round-trip flight to Miami from Atlanta
 * Spenser's Carbon Footprint Ecology Project**

-With Carbon Footprint Reducion -7 total tonnes of CO² -3.72 tonnes for house - 3.28 tonnes for car ( with Miami flight combined into mialage)

=Wind Energy/Windmill Project=

Leka's Science Project //Background Information: Wind power began in the 17th century B.C in Babylon when Hammurabi an emperor, began using it for his irrigation process. Ancient people would use wind turbines to power items from furnaces in 300 B.C. all the way to an organ in the 1st century. Today, wind is powering 19% of the electricity Denmark, 10% in Spain, 10% in Portugal, 7% in Ireland, and 7% in Germany.// My question for this project was ‘How is wind an alternate energy source?’ I made a windmill out of a Pringles can and tried to turn on a red LED light. Wind is very helpful to people and the environment. It does not produce pollution unlike fossil fuels but still gives us the same amount of electricity we would normally use. It is also cheaper, at only 1.9 cents/ kilowatt hour in 2006. Wind is also one of those things that will never run out. Though wind is very helpful to the society, it also has its downfalls. Windmills/turbines are large and moving. They are an obstacle for birds, as many have died from crashing into moving windmills. Windmills also get in the way of airplanes, since the plane’s radar shows the windmill as another airplane. In Boone, NC, there was a windmill called the //‘Howard’s Knob Windmill’//. It was taken down because the turbine made a swishing noise. The noise annoyed neighboring citizens. It also disrupted television signals. For my project, I cut out a Pringles can into diagonal pieces and glued them together. I attached the motor and light. The only problem was that it would only turn on if I turned it, not with the fan. The LED still worked, though. All I needed was a bigger fan!! Wind is a very helpful source for us humans. There may be a few problems, but we could work it out.

My name is Austin and this is my project on solar coking and this is my solar cooker. I have tried it under a heat lamp and I hope to try it under the sun. Under the heat lamp it didn't conduct enough energy because the lamp didn't get hot enough and I think it will work in the summer under the sun.

Hydroelectricity by Shyam. media type="custom" key="3576746" My project was made by cutting off the bottom of a milk carton and putting a cork with six spoon heads in it to turn a generator by turning on a sink while the milk carton was under it. We determine how much electricity we created by putting a generator with its wires connected to a voltmeter.

 * FRUIT ENERGY PROJECT by: Erica....................**

That's all. Okay so if listened to the poster at the top of the page you'll hear pretty much everything.This is the website the poster was talking about and it promised you were going to learn how to make the project. Okay so here we go......

1) Take any citrus fruit and put in a bolt on one side and a copper coin(penny) on the other 2) Then take the red wire and attach it to the coin( make sure all of the wires are stripped on both sides) 3) Then take the black wire and attach it to the bolt. 4) repeat. 5) Then attach all of your fruits by twisting the part of the wires that aren't being used together

SUPPLIES: .wires(red and black) .bolts .copper coins .lemon juice(can be used to up the voltage by a little bit, optional)

Also, as you probably learned from the poster, my project didn't exactly work, but don't leave the site because that. The only reason my project didn't work was because people kept eating my fruit and that means they'd have to peel it and your not supposed to peel the fruit. So the whole point of this story is for you learning to.......NOT PEEL THE FRUIT! This project was also a way to show an alternate energy. Who knows someday there can be a place where they take a bunch of fruit and convert it into energy. It would also make the Earth greener because they would have to plat a lot of trees. If it ever happens just remember it was my idea. So that's it you can move on to the next project now (eventhough you learned the most from mine)

=__How People Use Geothermal Energy__= media type="custom" key="3574822" by: Jack

Geothermal energy is energy generated from the earth. Geothermal power requires no fuel, and is therefore virtually emissions free and insusceptible to fluctuations in fuel cost. It also has minimal land use requirements.

__**These are some of the ways I showed how people use geothermal energy at a school.**___ __Recycling: Reduces waste on landfills.___

Solar Panel: More energy efficient than power lines. Green Roof: More energy efficient than regular roofs. It helps reduce heating bill__.

Hi, My name is Matthew. I made a solar panel. I hope you enjoy my project!!!! Thanks to Ehow.com, I was able to complete this project.

**Clifford's Wind Turbine**
media type="custom" key="3575626"

I made a wind turbine for my science project.I made it by putting coils of wires under a half cut bottle in a cardboard frame with a wooden dowel through the center and when you spin it, it would make power. You would first get a fan and blow it toward the turbine, spinning the two halfs of the bottle, spinning the earth magnets (enery magnets) to the electrical wires traveling into the voltmeter. The voltmeter would then show how much power the turbine made. Unfortunately, i had a problem with the electrical wire getting me no reading on the voltmeter. This project is still very fun and this link below will show the directions for my wind turbine.... []

media type="custom" key="3575674" Water Power by William.My name is Willliam and my project is about water power.I had to get these items tape, a magic marker, a milk carton, and nails.First, I cut of the top of the milk carton. Next, I put holes in the milk carton. After that, I tape down the holes. Then, I measure of far the water stearm went. the hole closes to the bottom went the farest it went 6 in.

Most Energy Effecent House Color -media type="custom" key="3597168"My project was done by building three house's out of popcicle sticks. I painted one of them black one of them white and let the last house stay the same natural wood color. Then i put them in the same amount of light and measured the tempurature of each house.
