Efficient initiatives to help protect the environment

Unfortunately, we're not quite there. Many of us believe that we lead lives that respect nature but our consumption habits give us away. Many little habits that seem to be sustainable are in fact polluting. Along with pollution, issues like depletion of resources, the rise of consumerism, and the "throw away" culture have led to serious issues. That being said, the fight's not over yet. Fortunately, more people than ever are both aware of and active in the protection of the environment. To protect the environment, waste management and recycling are crucial. When we recycle, used materials are converted into new products, reducing the need to consume natural resources. If used materials are not recycled, new products are made by extracting fresh, raw material from the Earth, through mining and forestry. R...

Virtual Lab - Programmi arvustus

Programm alustab lihtsamatest skeemidest ja muutub ajapikku aina keerulisemaks ja põhjalikumaks. Lõpuks õpetab programm õpilasel koostama skeeme mida leidub näiteks uksekellades, autodes ja muudes elektroonika seadmetes. Virtual Labs: Electricity kasutab erinevaid võtteid laste õpetamiseks. Kui õpilased on iseseisvad ja tunnevad elektriõpetust, võivad nad ise erinevad skeeme kokku panna, selleks saavad nad kasutada ikoone mis sõmboliseerivad erinevaid tarvikuid nagu näiteks juhtmed, mõõteriistad, takistid, akud ja palju muid. Vähem kogenenud õpilased saavad lahendada ülesandeid mis on tootja kooli versioonile sellest programmist kaasa pannud.. Nende hulgas on nii küsimusi kui ka pikemat lahendust nõudvad ülesanded. Programmiga on kaasas ,,Sci-Clopedia" mis õpetab õpilastele elektrifüüsikat ja sisaldab palju artikleid...

Education

Relaying my own experience is easy: I had a standard classroom approach, supplemented by inordinate reading. In only the briefest and least memorable instances did I receive any individual tutoring. Education is commonly thought of as the job of schools. Adults cry "educate our children!" Everyone has opinions about the best way to do the job. It is of urgent importance, and all the numerous factors are much studied, debated, and new (or old) ideas continually tested or retested. Some people say "it's as simple as . . . " and then name their pet peeve or passion. My view is not of an education specialist, but of one who loves sharing what I learn, and owes much to educators. Since I don't have an educational theory neatly worked-out, nor an outline of my perceptions, my intent is to addr...

Mõtteterad/aforismid

Sellistel päevadel läheb kõik viltu , isegi asjade alustamine ei tule välja . Iga hetk võid lootuseltult nutma hakata, isegi teadmata, miks ... Ma ei saa oma sõpradele päikesepaistelist ilma lubada, aga ma saan neil vihmavarju pea kohal hoida, kui sajab! Hinda seda mis sul on mitte seda mida sul pole. Sest, kui sa kaotad selle, mis sulle on kallis, siis sa alles hakkad mõistma, kui väga sa seda kõike tagasi tahaksid saada, aga võibolla on siis juba liiga hilja. Tuleb hinnata seda kõike, mis on meie ümber. Selleks, et teada, mis on kuristik, pole vaja sinna kukkuda. Ära naera teiste unistuste üle, neil on need vähemalt olemas . With one look , you could make me smile , now withouth even looking , you make me cry . Elu on nagu male , et seda võita , peab tegema õigeid käike , kuid lõppude lõpuks on see siiski vaid mäng ! Inimese väärtust ei hinnat...

Inglise keelt kõnelevate maade ajaloo eksamiküsimused

It is one of the most famous prehistoric sites in the world and is composed of earthworks surrounding a circular setting of large standing stones. The surrounding circular, earth bank and ditch, have been dated to about 3100 BC. Stonehenge was produced by a culture with no written language. Many aspects of Stonehenge remain subject to debate. There is little or no direct evidence for the construction techniques used by the Stonehenge builders. *The Celts in Britain and their legacy ­ The Cets lived in Britain in The Iron Age. They were warring tribes who were battleful amongst themselves as well as inter-tribal war. They were not centrally governed. The Celts brought iron working, iron ploughs and metal swords, horses, wheels and chariots - all these things gave them an instant superiority over the native tribes. The Celts built a number...

Hüdroenergia - ettekanne

Global energy use has risen by 70% since 1971 and continues to increase at the rate of 2% per year. There are many scenarios for future demand. One solution would be to use more hydropower. In 2005, renewable energy represented one-fifth of total power generation. Hydropower is the most advanced of the renewable and represents 87% of this production. 160 countries all over the world are using hydropower. Five countries make up more than half of the world's hydropower production. Those countries are: Brazil,Canada, China, Russia and the USA. (Production) *Most of the energy comes from the potential energy of dammed water driving a water turbine and generator. In this case the energy extracted from the water depends on the volume and on the difference in height between the source and the water's outflow. *Pumped storage hydroelectricity produces electricity to supp...

Norra - referaat

Island (0,968) 1. Luksemburg (77,089) 2. Norra (0,968) 2. Katar (72,969) 3. Kanada (0,967) 3. Norra (51,862) 4. Austraalia (0,965) 6. Singapur (47,426) Norra on arengutaseme poolest üks arenenumaid riike, sest üheks parimaks näitajaks on elektritarbimine inimese kohta. Maailmas on Norra teisel kohal elektri tarbimise poolest ühe inimese koha. Üks inimene tarbib seal elektrit umbes 24000kWh. Võrreldes Eesti 6000 kWh on see märkimisväärne tarbimine. Muidugi on see loogiline, sest Norra asub põhja pool, kus aasta jooksul on palju pimedat aega. Kuna elekter pole odav asuvad energiamahukad tööstused reeglina kõrgelt arenenud riikides. Tänu väga kõrgele arengutasemele on ka metsamajandus hästi ko...
