18 Ways To Green Your School

The following suggestions include ways to get involved in helping your local school go green as well as tips for your children to become green students. 

1.    Start an eco-committee of parents and interested teachers to organize and direct green activities and efforts at your school. In middle schools and high schools, students should be represented on the committee as well.

2.    Find out if your school has an environmental mission statement or "planet pledge" - if they don't, help establish one.

3.    Conduct an environmental survey or energy audit of the building and grounds and create a plan of action based on the results. Get students involved in the plan of action and have teachers discuss the issues with their students.

4.    Encourage teachers to include green topics in their curriculum. Offer to present a project or topic for discussion to your child's class.

5.    Buy your child vinyl and lead free lunch boxes.

6.    Send your child to school with a healthy lunch in a reusable container. Attempt to create a "trash free" lunch. 

7.    Buy your child a large, chemical free water bottle for them to use throughout the school day.

8.    Buy unbleached recycled-paper notebooks.

9.    If your older student carries a cell phone, ipod or laptop to school, consider a solar powered backpack to power her gadgets.

10.  Buy backpacks made from recycled materials.

11.  Buy non-toxic school supplies including glue, crayons and markers.

12.   Ask the teacher to use low-odor dry erase markers and dust free chalk. Offer to purchase them for the teacher if cost is an issue.

13.   Request that the school provides a clean, safe indoor environment and clean air by using non-toxic cleaners in the classrooms and throughout the building.

14.   Are toxic pesticides sprayed on the playground? Find out and petition for change. Present viable options.

15.   How is pest control handled inside the school? Help to make necessary changes by researching and presenting a better, chemical free solution.

16.   Request that school forms and notices be distributed through email when ever possible to cut back on paper use.

17.  Find coloring pages online. It is easy to find exactly what your child would like to color without having to buy – or waste – an entire coloring book that contains pages they are not interested in coloring.

18.  Encourage you child to get involved in the recycling effort within the school and to participate in any other going green programs.

report text "SKY"

 Sky

The sky is the part of the atmosphere or outer space visible from the surface of any astronomical object. During daylight, the sky of Earth has the appearance of a pale blue surface because the air scatters the sunlight.

At night the sky has the appearance of a black surface or region scattered with stars. During the day the Sun can be seen in the sky, unless obscured by clouds. In the night sky (and to some extent during the day) the moon, planets and stars are visible in the sky. Some of the natural phenomena seen in the sky are clouds, rainbows, and aurorae. On Earth, birds, insects, aircraft, and kites are often considered to fly in the sky. As a result of human activities, smog during the day and light radiance during the night are often seen above large cities (see also light pollution). In the field of astronomy, the sky is also called the celestial sphere. This is an imaginary dome where the sun, stars, planets, and the moon are seen to be traveling. The celestial sphere is divided into regions called constellations.

Light from the sky is a result of the scattering of sunlight, which results in a blue color perceived by the human eye. On a sunny day Rayleigh scattering gives the sky a blue gradient — dark in the zenith, light near the horizon. The blueness is at the horizon because the blue light coming from great distances is also preferentially scattered. This results in a red shift of the far lightsources that is compensated by the blue hue of the scattered light in the line of sight. In other words, the red light scatters also; if it does so at a point a great distance from the observer it has a much higher chance of reaching the observer than blue light. At distances nearing infinity the scattered light is therefore white. Far away clouds or snowy mountaintops will seem yellow for that reason; that effect is not obvious on clear days, but very pronounced when clouds are covering the line of sight reducing the blue hue from scattered sunlight.

The scattering in a 90 degree angle is still half of the scattering that reflects or goes forward. This causes the blue sky to be almost evenly colored and thin clouds to form a white area around the sun, because the big particles the clouds are made of are scattering preferentially only at low angles. The color of the clouds is also due to scattering and a cloud at a small distance has the white color because all the light from these clouds is scattered multiple times in the mass of particles and no wavelength effects will be observed.

The sky can turn a multitude of colors such as red, orange, purple and yellow (especially near sunset or sunrise) and black at night. Scattering effects also partially polarize light from the sky, most pronounced at an angle 90° from the sun.

I.                   Macam-macam penyakit pada ginjal

No.	Jenis  Penyakit	Identifikasi	Penyebab	Pengobatan	Gambar
1.	Batu Ginjal	Suatu endapan yang berasal dari garam kalsium	Endapan batu ginjal  yang dapat berada di dalam rongga ginjal,saluran ginjal,ataupun kandung kemih yang menyebabkan urine sulit keluar dan menimbulkan rasa nyeri.	Untuk menghilangkan batu ginjal dapat dilakukan dengan pembedahan(operasi) atau batu ginjal juga dapat dipecahkan menggunakan sinar laser.
2.	Gagal Ginjal	Suatu kondisi dimana kedua ginjal mengalami kerusakan permanen dan tidak dapat menjalankan fungsi sebagaimana mestinya	Suatu keadaan jika satu atau kedua ginjal tidak dapat berfungsi ,sehngga urea yang tertimbun dalam tubuh akan bersifat racun dan dapat mengakibatkan kematian.	Untuk menggantikan fungsi ginjal tersebut ,penderita mempunyai dua alternatif,yaitu  mengembangkan ginjal buatan atau pencangkokan ginjal baru.
3.	Diabetes Insipidus	Suatu keadaan yang ditandai dengan adanya produksi urine berlimpah dan disertai rasa haus yang amat sangat.Para penderita dapat mengeluarkan urine sebanyak 20 liter sehari(10-20 kali rat-rata).	Penyakit ini disebabkan ginjal mengalami kekurangan hormone Antidiuretik (ADH) sehingga kemampuan mereabsorpsi menjadi hilang.	Untuk mengjindari dehidrasi fatal,penderita harus mengganti kehilangan air tersbut dengan meminum air segar.
4	Asidosis tubulus renalis (ATR)	suatu penyakit ginjal khususnya pada bagian tubulus renalisnya.Bagian dari ginjal yang bernama tubulus renalis tidak dapat berfungsi sebagaimana mestinya,sehingga hanya sedikit asam yang dibuang ke urine.	Penyakit ini disebabkan factor keturunan atau bisa timbul akibat obat-obatan,keracunan logam berat atau penyakit autoimun	Sejauh ini kedokteran belum menemukan obat atau terapi untuk menyembuhkannya,karena penyakit ini tergolong sebagai kerusakan organ tubuh. Sementara ini penanganan dari penyakit ini baru sebatas terapi untuk mengontrol tingkat keasaman darah,yaitu dengan memberikan obat yang mengandung zat bersifat basa.

II.                 Macam-macam penyakit hati

No.	Jenis Penyakit	Identifikasi	Penyebab	Pengobatan	Gambar
1.	Hepatitis	Radang atau pembengakakan hati.Hepatitis merupakan penyakit yang sangat umum,bahkan dapat terjadi pada orang yang system kekebalanya baik.Hepatitis dapat mengakibatkan goresan/pengerasan hati sehingga fungsi hati menjadi gagal.	Hepatitis dapat disebabkan oleh,virus alcohol,narkoba,obat-obatan(termasuk obat yang diresepkan),atau racun.	Dengan memberikan vkasinasi kepada penderita.Vaksinasi merangsang tanggapan oleh system kekeblan tubuh untuk membuat antibody terhadap infeksi tertentu.Namun cara vaksinasi ini hanya bias diggunakan oleh penderita hepatitis B.
2.	Kanker hati		Hati terdiri atas beberapa sel sehingga jenis tumor dapat berbentuk  pada organ ini.Beberap diantaranya bersifat kanker dan yang lainya bersifat tidak berbahaya.	Penyembuhan dari penyakit ini tergantung pada jenis tumor yang diderita.
3.	Sirosis	Sirosis merupakan puncak dari penyakit hati yang kronis dan menyebabkan guratan pada hati sehingga hati menjadi tidak berfungsi.	Keadaan tersebut dapat mengakibatkan berbagai macam komplikasi termasuk akumulais cairan dalam perut,ketidaknormalan pendarahan,dan meningkatkan tekanan pembuluh darah hati.	Penyakit ini menyebabkan ketergantungan alcohol dalam jangka panjang.Maka para penderita sirosis harus mengikuti rehabilitasi untuk para ketergantungan alcohol,agar penderita tidak berketergantungan lagi dengan alcohol.
4	Batu empedu	batu empedu adalah timbunan satu atau lebih batu kecil di kandung empedu.	-          Empedu terlalu mengandung banyak kolestrol. -          Gangguan darah (anemia sel stabit) -          Empedu kurang mengandung garam empedu	Biasanya penderita batu empedu diberikan obat-obatan yang berbasis asam empedu gunanya untuk mengencerkan batu empedu yang terbuat dari kolestrol.
