supporter of recycling. Thesis: While recycling might be considered to be “inconvenient” to some‚ so many common materials can easily be recycled. Although there are plenty of great reasons to recycle‚ our societies carelessness causes damage to our environment. (Transition) Over sixty percent of the garbage each person throws into the trash daily could have been recycled. I. First point: There are many substances that are recyclable

Recycling Speech Outline Quang Nguyen 8/16/2012 Speech 275 Recycling Speech Outline INTRODUCTION: I. Did you take out the trash? That’s the question that has been frequently asked of you to do. Whether from work or home‚ everyone has trash to throw out. But most people do not care about recycling enough to make the earth a better place. Recycling is painless and it doesn’t take that much time to do. Think of how much harm you cause to the environment when you do that. There’s already enough

Recycling Litter‚ litter‚ everywhere and nary a piece gets recycled. Why? It seems pretty simple to put litter back into the recycling loop and that’s just what the Nicodemus Wilderness Project does after a cleanup. The majority of the litter that we collect during our trail cleanups is recyclable. There are lots of glass bottles‚ paper products‚ plastics‚ and aluminum cans littering our wild lands and waters. Removing this litter from the shoreline‚ mountains‚ and other wilderness areas prevents

Introduction Recycling is processing used materials (waste) into new products to prevent waste of potentially useful materials‚ reduce the consumption of fresh raw materials‚ reduce energyusage‚ reduce air pollution (from incineration) and water pollution from landfilling by reducing the need for "conventional" waste disposal‚ and lower greenhouse gas emissions as compared to virgin production. Recyclable materials include many kinds of glass‚ paper‚ metal‚ plastic‚ textiles‚ and others. Nowadays

Chemistry Batteries [Chemistry HSC Course-1] What is an Anode? An anode is the negatively charged electrode of an electrical device but in this a primary cell‚ that supplies current. What is a Cathode? A cathode is the positively charged electrode of an electrical device which in this case is a primary cell‚ that supplies current. What is Current? A flow of current which results from the ordered directional movement of electrically charged particles. A current is the rate of flow of charge

appear to be fragile and light‚ their negative environmental effect is devastating. Plastic bags may cause large amounts of pollution in every step of their limited life cycle‚ from the extraction of raw materials‚ production‚ transportation‚ and recycling or disposal. Plastic bags can be defined as the most damaging form of environmental pollution. They can have a damaging effect on marine animals and wildlife in addition to the aesthetic effects on beaches‚ parks‚ and trees. Plastic bags are potentially

GENERAL FEEDBACK ON BACK BAY BATTERY SIMULATION Excerpts from the Simulation’s Teaching Note The Division Manager’s Dilemma The Division Manager at Back Bay Battery faces the classic innovator’s dilemma. While Back Bay has a successful business that is generating reasonable profits in NiMH batteries‚ a new technology in the form of ultracapacitors looms on the horizon. For its existing customers‚ ultracapacitors are a long way from meeting current customer

scalloped‚ but how about taking the place of a car battery? If a potato can replace a AA battery and light up a light bulb‚ who’s to say multiple potatoes couldn’t serve the same purpose in a car? Potatoes use the acids within them to start a reaction between the copper and zinc wires on either side of it. This reaction causes the flow of electrons passing through the wires and using the positive and negatively charged electrons to power the bulb. Car batteries also run off a positive and negative charge

Lead acid cells were invented in 1859 by the French Physicist Gaston Plante‚ and are the oldest types of rechargeable batteries. These types of batteries typically weigh at 5kg‚ but can range from half a kilogram to over 30 kilograms on the consumer market. Though their chemistry means a very low energy-to-weight and energy-to-volume ratio in comparison to other modern batteries‚ their ability to supply high surge currents means that the cells maintain a large power-to-weight ratio. This makes them
