...Have you ever wondered how much energy your family us in a day? In our world today we have all kinds of new knowledge and technology to help us save energy available for us. Some of this comes in the form of light bulbs and other is just to train family members to shut the light off when they walk out of the room. Either way with a product or by turning a light off we should all do our best to save energy. I believe this is a moral issue because some people just do not care how much electricity they waist or that by using certain products they could save our planet from pollution. Pollution is another issue that is big concern in our world today. The community where I live has a chemical plant not far from it and over the years there have been many struggles to get them to dispose of their wastes properly. This is our world and if we do not take care of it by conserving energy and limiting pollution what will it be like for our children and grand children? Will there even be a world? Will there be diseases worse than cancer? These issues I believe are more of moral issue than anything else and it all comes down to respecting others as well as our homes and environments. To solve these issues I believe that there should be training available in the schools, work places and communities. Factories that have chemicals or cause any other kind of pollution should be punished for not obeying the laws and regulations on dumping wastes. Every employee should be made to take part...

...Lemon Battery Grade Level: 6 Strand: Energy and Control Topic: Transforming electrical energy into light Overall Expectations: design and construct a variety of electrical circuits and investigate ways in which electrical energy is transformed into other forms of energy Specific Expectations: investigate ways in which electrical energy can be transformed into other forms of energy (e.g., into light) Materials Needed: • 3 lemons • 3 shiny copper coins • 3 zinc plated screws • 4 wires, preferably with alligator clips on the ends. • a small knife • small paper sticky labels • a light emitting diode (LED) with a low voltage rating. We used part 276-330 from Radio Shack. • a plastic 35mm film canister or similar small container. Use an opaque one, preferable black, not one made of clear plastic. • a nail Procedure: • • • First, roll all of the lemons, one at a time until they feel squishy. The purpose of this is to release the juice inside the lemon. This step helps you get the maximum response from your lemons. Push and then twist a zinc-plated screw into one of the lemons about 1/3 of the way from one end. With the knife, carefully cut a 1 cm (3/4 in) slit into the lemon about 1/3 of the way from the other end. Insert a copper coin into the slit so that about half of the coin is inside the lemon. Note: Make sure you use a shiny new coin for this. If it is old and dull, polish it with steel wool. ...

...Energy Flow in Ecosystem and Its Importance in Crop Production By gachura10@gmail.com Course Tutor Institution, City Date Energy Flow in Ecosystem and Its Importance in Crop Production Introduction An ecosystem is made up of of the organic community that take place in some area, and the bodily and biochemical influences that make up its lifeless or abiotic environs (Fraham, 1984: 143). There are several instances of ecosystems: a fish pond, a plantation, a river mouth, a savannah. The limits are not static in any impartial way, even though occasionally they look clear, as with the water's edge of a small fish pond. Typically the margins of an ecological unit are selected for real-world aims having to do with the objectives of the specific study. According to Perry (2008), study of ecological unit mostly comprises of the study of sure procedures that relates the living, or biotic, constituents to the inorganic, and abiotic constituents. Energy changes and biogeosubstance transformation are the key procedures that include the area of environment conservation. Ecology normally is well-defined as the connections of creatures with one another and with the environs in which they are living. Ecology can be studied at the level of the separate organism, the inhabitants, the community, and the environment. studies of ecology at individuals are concerned generally about composition, reproduction, growth or performance, while studies of ecology at inhabitants...

...meeting. I want to take a few minutes to discuss and educate everyone on the importance and many advantages of conserving energy. Energy is very important to human population because most people depend on energy to light their homes, cook, to heat and cool their homes, and to bathe. There are two types of natural resources renewable and nonrenewable energy sources. Renewable energy recourses are reusable and can replenish and the nonrenewable energy sources are not reusable, and the resources are not capable of replenishing. A few examples of renewable energy sources are wind, water, and solar energy. Solar energy can be used to heat homes, buildings, and water. The energy generates by the solar mirrors absorbing the sun which starts the engine to electricity. A few examples of nonrenewable energy resources consist of coal, oil, and natural gases which will eventually run out within time. We as society can contribute a helping hand in saving our natural resources and conserving our energy by checking for any water leaks in or around the sinks, toilets, and faucets. Fixing any kind of water leak will help save on water and can help cut back on one’s water bill. People may also reduce energy by simply turning off the lights in unoccupied rooms. This will help conserve electricity and at the same time save people money on their electric bill. Another way of conserving energy and helping the environment to be cleaner would be carpooling with others to save on gas and pollution that...

...Unit 1 Revision (higher tier) Energy There are 9 different forms of energy: Light Heat Chemical Kinetic (movement) Electrical Elastic (Gravitational) potential Nuclear Sound Energy is never created or destroyed! Energy is transferred from one form to another form. Not all of the energy transferred by a device is useful energy. Potential energy is stored energy. All energy will eventually spread out to the surroundings as heat. Sample question 1 Sankey diagrams and efficiency Sample sankey diagram for a light bulb Sankey diagrams are ways of representing the different energy transformations that take place in different electrical devices. The start of the sankey diagram shows the total energy going into the device. The diagram then splits off into different sized arrows to represent the other energy transfers that take place, the bigger the arrow the larger the energy. The energy entering the device must equal the energy leaving the device. To know how good a device is at transferring energy you need to be able to calculate the efficiency. To do that you need to use the following equation (which will be given in the exam) OR So for the above example the answer would be Efficiency= 10100=0.1 The closer the efficiency is to 1 the more useful energy the device is transferring. So for the light bulb example we got an efficiency of 0.1, so the light bulb isn’t very good and transferring useful energy. Sample question 2 Kinetic...

...Unit 3 Assignment 1: momentum and energy 1. An ice-skater is twirling with her arms extended a. If she were to close her hands the momentum to her twirling will increase with less resistant from hands being extended picking up wind resistant’s. b. Then energy that was resistant with the hands extended transfers to the body momentum its twirl conserving its energy as she spins. Page 100-101 14. A woman stuck in the middle of a friction-less ice pond can thrust her arms causing a momentum energy towards the direction she thrust towards. No friction below to stop the energy thrust direction to the shore. 36. The ke is at max at the start of its momentum left side. As PE will be at its equilibrium position which is it’s at its max, and reaches half at the end of its swing. Ke/pe 46. if the ball falls and there is air resistant the energy is then changed by other factors of energy. Now if the air wind was to be pushing the same direction then it would have a increase of KE. In which case if it is just there to resist then the ke is decreased depending if the ball doesn’t already have wings. 54. if two object have the same KE then the momentum is the same. Not applying the mass of the item nor having to include the environment. It both was to move with no other KE to resist then both would be going at same momentum whether is big or small.

...equipment. Solar water heating is when solar panels are on the roof and captures sunlight using solar collectors and transfers it to heat energy. This is a very efficient system because it is inexpensive and cheaper than regular electricity. The popularity for solar water heating has grown tremendously. Other countries are now using it in businesses and in neighborhoods. The energy is very renewable. Its average cost for the solar panels are about three hundred dollars a roof top. Home owners get reimbursed thirty percent after using the solar panel energy. Beer and food companies are now trying to use solar water heating in their factories. When considering beer companies use large amounts of hot water to make beer. In Cyprus nine out of ten homes are now using solar water energy which is amazing. I think solar water heating system is brilliant just because it conserves energy. In the United States we use solar water energy to heat up pools. So I think the United States should be more active in the solar energy. In Australian homes they were accustomed to use wood to heat their homes. Now with the new energy Australians get the benefits of having a heating system. So basically I don’t see a downside with solar water heating. It seems to benefit everyone financially. Who knew one farm could open the minds of the whole world for conserving...

...Energy Resource Plan June 03, 2012 Energy Resource Plan This Homeowner’s Association meeting is taking place to discuss the importance of the energy issue we are facing within our communities. The reason why conserving energy is important is because we can save our environment and our climate from further damage. Not only will conserving energy assist in our environment but it will also save everyone money. In order to conserve energy we first need to know the difference between renewable and non-renewable resources and the methods we can use to help conserve energy. Non-renewable resources include oil, coal, natural gases, and nuclear energy. Non-renewable refers to not being able to replace these sources once they run out. Non-renewable resources are harmful to our environment because of all their chemicals such as when burning pollutes our air and their leaks and spills pollute our ocean. Renewable resources include solar power, wind energy, biomass fermentation, tidal energy, and a few more. Renewable energy generates directly from the sun, wind, rain, and tides. The use of renewable technologies will help save money and boost our economy in the process. Here are a few methods to help conserve energy indoors: 1. Turn off the lights and electronics when they are not in use. 2. Use energy saving light bulbs. 3. Insulate doors and windows. Three methods that will help the environment in the process are: 1.

...How to Teach Children to Conserve Energy It is important that we teach our children ways to practice energy conservation. Instructions 1 Explain to your children just how important conserving energy is. They may have heard you talk about it or mention it, but do they really understand what it means. Try giving them examples of why it is so important. There are many books that can help you explain the importance of energy conversation to your child and also give some tips on how to do it. 2 Make sure you practice what you preach. If you aren't being a good example, then your children will have no one to follow. Don't just tell them to turn off the lights when they leave the room, show them by always turning off the lights yourself. 3 Rent or find a video online about energy conversation techniques. Fun cartoon characters like the electricity lightening bug can help make learning fun and also make children take an active part in what they see. 4 If your children are older and they are not very good at conserving energy, try a one month energy experiment. While you may have to demand or bribe your children to participate, it will be well worth the effort. Show your children an electric bill and how many watts of energy your family uses in a month. Then go over ways to cut down your energy costs. For one month, make it a conscious effort to make sure that everyone does things like turning off lights when leaving a room, doesn't leave the television on constantly...

...Energy Conservation Plan Keenan Williams SCI 275 April 15, 2012 Sarah Franklin Energy Conservation Plan Energy is something that is a necessity for the human race to function. People are very ignorant when it comes to conserving energy, which in turn wastes what little non renewable resources remaining and becoming scarcer. A non renewable energy source is something that cannot be reproduced or grown; it comes from sources that can be completely depleted, such as fossil fuels, oils, and natural gases ("U.s. Energy Information Administration", ). When our non renewable sources start becoming harder to obtain, the price to use them goes up. The majority of the energy we use comes from non renewable sources. Energy is wasted daily basis. Leaving lights on during the day, leaving televisions on when no one is watching it, having multiple electronics plugged in to the wall instead of a surge protector, leaving the air conditioner running when no one is home, and doing laundry all throughout the day instead of doing it when the rates of electricity is lower are all ways that energy is wasted. A good way to stop the wasting of energy is to avoid those mentioned activities. These are just small things people can change in order to conserve energy, and if everyone would do it, it could make a big difference. The issue of energy conservation has both living and non living contributing factors. The biggest living contributing factor...
