switch as someone leaves a room or unplugging a device when not in use. From these small acts‚ the beginning seeds of energy conservation can be sown. Energy conservation has become one of the most hotly debated subjects in the world. Old power plants are struggling to keep up‚ sometimes causing power shortages or “brown outs”‚ and new power plants are being built‚ but most of the new plants still use the same technology as their predecessors. Some have even been ‘repackaged’ to appear cleaner

Middle school students should not be drug tested because it invades students rights and there is little to no evidence to prove the program works. The student’s privacy is invaded when they are forced to be tested for drugs or alcohol with little notice and are unsupervised when doing so. There is not much evidence that shows these programs work as far as getting students to stop taking the drugs or alcohol(it’s rare that they even were taking them in the first place). Middle schools should not be

Contents[Show] The energy of an object is its ability to do work. Energy is the cause and work is its effect. Therefore both work and energy have the same units‚ which is joule (J) in the SI system and erg in the CGS system. Energy is also a scalar quantity. Energy exists in many forms. Examples Mechanical energy which is either in the form of potential energy or kinetic energy or a combination of the both‚ electrical energy‚ light energy‚ thermal energy‚ nuclear energy and sound energy etc. Potential

Lab #7: Thermal Energy Heat is thermal energy being transferred from one place to another‚ because of temperature changes. This can take place by three processes. These three processes are known as conduction‚ convection‚ and radiation. When we place two objects with different temperatures in contact with each other‚ the heat from the hotter object will immediately and automatically flow to the colder object. This is known as conduction. Some objects make excellent conductors of heat while

Each trophic level shows how energy and biomass flow through a food chain however it is eventually lost as heat. These levels consist of: biomass of producers‚ those consumed‚ and those not consumed. The first trophic level has the producers which graze the food chain‚ grazers consist of the

requires “burning” food for energy. How much energy is released when food burns in the body? How is the calorie content of food determined? Let’s investigate the calorie content of different snack foods‚ such as popcorn‚ peanuts‚ marshmallows‚ and cheese puffs.
