...On April 22nd, 2015 Lakeland High School FBLA held a very special meeting to celebrate Earth Day. Our original plan was to go outside on Earth Day and clean up the garbage outside of our campus, unfortunately, we were unable to do this due to the inclement weather. However, Lakeland High School's current president, Marlon Restrepo came up with another way to celebrate Earth Day. His idea was to create a bulletin board which would display all the good deeds to help the environment that the student and faculty members of Lakeland High School did throughout the year. Throughout Earth Day members of FBLA walked the hall and handed out colorful leaves where we asked them to write down one good thing they have done to help the environment. We received...

...1 cinta untuk bumi kita Happy earth day Hari ini bertepatan pada tanggal 22 april , kita memperingati sebagai hari bumi. Namun apakah selama ini kita hanya memperingati hari bumi pada tanggal itu saja ? apakah kita hanya membuang sampah pada tempatnya, mengurangi limbah, listrik, polusi pada hari itu saja ? kalau jawaban sebagian dari kita adalah ‘iya’ maka kasihan bumi kita, mereka hanya kita perhatikan saat tanggal 22 april saja, sedangkan di hari lain, kita sering menyakiti mereka, kita sering membuang sampah sembarangan, memborosokan listrik, dan memperlakukan pohon dengan seenaknya. Padahal, selama ini mereka telah memberikan udara yang segar, hawa yang sejuk, kerindangan, ketenangan, dan menjadi sumber energi bagi kita kaum manusia dan hewan. Bumi semakin lama, semakin tidak terkontrol, semakin panas dan cuaca tidak menentu, es di kutub utara mulai mencair dan banyaknya lahan-lahan di kota besar dibangun ruko-ruko, perumahan, persawahan, dan lain-lain tanpa diimbangi dengan penanaman pohon-pohon penyerap oksigen. Polusi juga semakin memenuhi udara, hawa menjadi panas dan banyaknya karbon dioksida bertebaran dimana-mana, ditambah lagi dengan tempat pembuangan sampah yang semakin hari semakin menggunung, dan tidak terpisahkan antara sampah organik dan sampah non organik. Mungkinkah anak cucu kita dapat merasakan manfaat dari tanaman hidup ? 1 cinta untuk bumi kita, walaupun hanya 1 cinta saja kita berikan untuk bumi kita, jika setiap dari kita...

...Problemele sociale ale României de azi * Istoria României are ca moment fondator anul 1989, cînd puterea mondială existentă se prăbușește pentru a da naștere unei noi lumi, unei noi ordini mondiale, în care bipolaritatea puterii din perioada Războiului Rece este înlocuită cu dominația unei singure puteri SUA. Dizolvarea URSS are o influență decisivă asupra țările est-europene, ca România, care renunță la sistemul comunist și se îndreaptă spre înfăptuirea reformelor democratice. * Multiple probleme sociale nu sunt luate în seamă de cei de la conducerea țării care s-au perindat după 1989, şi nu sunt nici pe departe nici în prezent rezolvate, iar între timp altele la fel de grave apar şi afectează din ce în ce mai mult viaţa poporului român. Problemele existente sunt de gen politic, economic și social. * Evoluţia demografică a României Factorii care au contribuit la scăderea natalității României sunt: * modificări în structura forţei de muncă, * manifestarea fenomenul migraţiei forţei de muncă, * modificări în sistemul de protecţie socială a societăţii româneşti, * modificări permanente ale sistemului de învăţământ. * Scăderea natalităţii: Condițiile nefavorabile pentru nașterea copiilor Îmbătrînirea populației * Condițiile nefavorabile pentru nașterea copiilor * - Statisticile oficiale confirmă că numărul noilor născuţi proveneau din mame a căror vârstă era in mediu de 15 ani şi care aveau...

...Let’s save the ‘Mother Earth’ The noble ‘Earth’ has bestowed the human beings with incredible and beautiful nature in the form of mountains, rivers, forests and various natural resources that helped human beings to survive and initiated our evolution. So, now it’s our time to save our planet from the challenges which are threatening the existence of the earth… The life of Human beings originated on the planet Earth .The “Mother Earth” is calling us for her protection. People have become selfish and they are killing the beautiful forests, damming the rivers and making more concrete walls without even realizing that by doing these activities, they are giving invitation to the termination of their own existence. Our earth is burning from both ends as the river beds are running dry. The plants and mammals are like us-living things. The biggest challenge that our earth is facing today is ‘global warming’, the glaciers are melting, sea level is rising, & the climate is changing on a fast pace. So, we must help to save them all. World Earth Day is celebrated all over the world annually on 22nd April. This time; it will be the 40th anniversary of World Earth Day. | Origin It was first launched by honest efforts of the US senator Gaylord Nelson on April 22, 1970 from Wisconsin along with Denis Hayes as the main organizer of the activities for the grand event. It is really heartening to know that even at the commencement of the Earth Day; approximately twenty million...

...According to “Earth Day” by Claudia Atticot and Alexandra Manning, “The average American produces more than four pounds of garbage per day.” A lot of the trash thrown away is recyclable. We throw away paper or plastic that could be used today. Our Earth is being trashed and Gaylord Nelson wanted to help it by having Earth Day to encourage people to recycle and make our world better. In fact, plastic is a big factor and part of all of the recycling trouble. According to the passage “Earth Day” by Claudia Atticot and Alexandra Manning, “In 2012 the U.S. produced 32 million tons of plastic. Only 9% was recovered from recycling.” If we had recycled more of that plastic, we could power a computer for 25 minutes. This shows that we can take trash...

...LECTURE 2 Earth-Sun Relationships and Illumination of the Globe I. Earth-Sun Relationships: Why we have to understand? Because by understanding earth-sun relationships one will be able to determine the apparent path of the sun in the sky, the angles at which sun's ray (light) strike, the lengths of day and night, and the occurence of seasons. The earth is turning on its axis at the same time that it is moving in a path about the sun, and because the earth's axis is tilted with respect to the plane of its orbit, therefore, it will be much easier for us to view these relationships in 3-dimension, or to view the earth from space. II. Motion of the Earth: Rotation and Revolution A. Rotation: The spinning of the earth on its polar axis. Direction of Rotation: is from west to east (eastward), eastward rotation of the earth. Looking down upon the North Pole - it is counterclockwise rotation; clockwise movement on the South Pole. Time of Rotation: Mean Solar Day - consisting of 24 mean solar hours, it is the average time required for the earth to make one complete turn (rotation) in respect to the sun. Velocity of Rotation: rate of travel of a point on the earth's surface in a circular path due to rotation. Angular velocity (constant on earth) and linear velocity. Equator: 25,000 miles / 24 hrs = 1050 miles / hr 40,000 km/24 hrs = 1700 km/ hr 60 N & S = 525 miles / hr = 850 km / hr 90 N & S = 0 mile / hr We are unaware of this motion because the...

...Days on the Planets We are all accustomed to thinking of a day as a period of 24 hours. Many people often wonder how and why a an hour consists of 60 minutes and a day is divided into 24 hours. We can all tell time and we schedule our appointments and dates around time and day all the time. No one ever really stops to look into the history of the origin of time and how it was determined to be divided upon. However, that definition is a narrow one that only applies to planet earth., but what about other planets? One day is the length of time it takes for a planet to complete one single rotation on its axis which is 360°. Since all of the planets rotate at different speeds, the length of a day on each one differs. The definition of a day will explain just how many hours are in a day for Earth, Venus, Mars, Jupiter, Saturn, Uranus , Neptune, Mercury and Pluto. Explanation of the units of an hour and day There is documented evidence of the use of sundials that were used by Egyptians as early as 1500 B.C.. Sundials were stakes that were strategically placed in the ground so that they can indicate the time by the length and direction of the resulting shadow. A duodecimal system was used to divide the time period between sunrise and sunset into 12 parts. The number 12 was significant because it is the number of lunar cycles in a year. The night sky was divided by 12 and a circle into 360 degrees. They divided the day and night each into 12 hours. The hour was split...

...Original Creation of the Earth (The Big Bang vs. Six-Day Creation) TANITKA C. SMITH PHSC210_A24_201240 Debora Ladner December 3, 2012 INTRODUCTION The Big-Bang Theory, accepted widely by atheists and many scientists, simply says this: between 10 and 20 billion years ago a “bang” or explosion occurred from a single point in nothingness and with the scattering of googles of atoms, the earth came into being. An eruption of sorts occurred, haphazardly distributing the smallest particles of matter that miraculously adjoined themselves to create living, breathing organisms and every other object on the earth. Every word of the Bible is true. Every day, creation scientists are finding more and more evidence to support the six days of creation. There is nothing wrong with science, but in the end it is the fallible word of man. YOUNG EARTH At its simplest, evolution is a hypothesis which claims that all life has descended with modification from a primitive single celled organism in the remote past. The development has been one of increasing complexity. Originally, the first cell evolved from a preexisting organic “soup” in a primeval ocean, which in turn developed from chance conglomerations of inorganic chemicals. Ultimately, these chemicals themselves were produced by the “Big Bang” origin of the actual universe. Against overwhelming evidence it is said that the Big Bang happened billions of years ago, and gives argument that the earth and the universe are only...

...learnt so far. A greenhouse is a house made of glass. It has glass walls and a glass roof. People grow tomatoes and flowers and other plants in them. A greenhouse stays warm inside, even during winter. Sunlight shines in and warms the plants and air inside. But the heat is trapped by the glass and can't escape. So during the daylight hours, it gets warmer and warmer inside a greenhouse, and stays pretty warm at night too. This is because the heat received from the sun is trapped inside the greenhouse by the glass. The Earth is also like a greenhouse. During the day Earth’s surface warms up in the sunlight. At night, the surface cool, releasing the heat back into the air. But some of the heat is trapped by gas like carbon dioxide in the atmosphere. These gases, called greenhouse gases, work like the glass walls and the roof and keep the earth warm. This is global warming and it is making the earth dangerous planet. Unfortunately, we are making the earth too hot. We are using oil, gas and...

In a.c. circuits, 'reverse polarity' describes a situation in which a device, such as a socket outlet, is wrongly wired -with the line and neutral conductors interchanged. The spreading of the sea floor comes from magma oozing up between the cracks between continental plates as lava. This lava subsequently cools rapidly and forms solid rock. The primitive atmosphere was mainly composed of CO2. However, with the emergence of life, this CO2 was reduced in photosynthesis and increased Oxygen. Now our atmosphere is mainly composed of Nitrogen. the tilt of the earth affects the earth's climate by when the north is tilted closer to the sun it is warmer and sunny for six months strait. but when the north is tilted away it is colder and dark.. These pollutants are sulfur dioxide, particulates (such as dust and smoke), carbon monoxide, volatile organic compounds, nitrogen oxides, ozone, and lead.

...SCI 321 Research Project July 28, 2012 Mercury - History and Naming Mercury, the planet closest to the Sun, circles the Sun faster than all the other planets in our solar system, which is why the Romans named it after the swift-footed messenger god Mercury (Space exploration, 2013). Human observers have been looking up at Mercury since at least the time of the Sumerians – the 3rd millennium BC (The planet mercury, 2013). These Greek astronomers believed even then that Mercury (and Venus) both orbited the Sun, and not the Earth. Mercury was the god of commerce, travel, and thievery in Roman mythology, hence the naming of Mercury. Slide 2 Early beliefs of Mercury Mercury was known since at least Sumerian times roughly 5,000 years ago, where it was often associated with Nabu, the god of writing (Mercury, the sun's, 2013). Mercury was also given separate names for its appearance as both a morning star and as an evening star (Mercury, the sun's, 2013). Early beliefs thought that perhaps there were two different planets. However, Greek astronomers knew that both names referred to the same planet (Mercury). Back in the nineteenth century, astronomers made very careful observations of Mercury's orbit, but they could not explain the orbit adequately using Newtonian mechanics (The planet mercury, 2013). There were discrepancies between what they observed and what was mathematics predicted. This problem would last for decades. Einstein's General Theory of...

...discovered throughout the nineteenth and twentieth centuries , (that date back as far as the third millenium B.C.) Sumerologists, such as Samuel Noah Kramer, have deciphered the oldest cosmogonic concepts ever found . Kramer explains that because the Sumerians lacked "scientific methods of definition and generalization " to make sense of the origins and the working of the universe they attempted to provide explanation through the use of poetry, epic tales and hymns . The only scientific information they had access to was what could be seen around them, that being Earth, Air, Heaven and Water , and according to the Ancient Sumerians it was through these essential elements that the universe came to be and it begins with Nammu, the primeval sea. From the primeval sea was born An (Heaven) and Ki (Earth), a singular mass in the form of a mountain. From the union of An And Ki came Enlil (Air) which in turn separated Heaven from Earth, An carried off heaven and Enlil carried away his mother Ki. Through the union of Ki and Enlil and subsequent couplings of gods begotten by them, came the luminaries and the organisation of the universe . The Book of Genesis was...
