10 Ways to Go Green at School
By
Beth Newingham
on April 21, 2011
While it's certainly worthwhile to use Earth Day to help
students understand the importance of “going green,” it’s also crucial
to encourage students to be environmentally conscious throughout the
year. In this post, I will share a variety of projects and activities
that my own school has implemented to become an official “green school”
in Michigan. I hope you can use these ideas to help your school go
green, but I am also looking forward to reading your comments and seeing
how schools around the world are helping to save our planet.
1. Participate in International Walk to School Day
International Walk to School Day promotes
a healthy lifestyle and encourages students and parents to think about
the effects that cars have on the environment. On this day, all students
pledge to walk or ride their bike to school. Since our school is in the
middle of a neighborhood, this is a very realistic goal for our
students. However, even if most students at your school take a bus or
are driven by a parent, students can still be dropped off close to the
school and walk the last half mile. The goal is for students and parents
to realize that replacing car trips to school with walking or bicycling
can help reduce air pollution.
You can incorporate this activity into your curriculum by asking your students to explore the question: “What impact does car transportation have on the local environment?” Some
upper elementary students in our district have conducted simple air
pollution experiments and analyzed the findings in the context of their
own weekly trip tally, which documents their comings and goings about
town by car, foot, bike, and public transportation. Students then
analyze their own travel data, as well as that of the whole class, and
explore strategies for reducing air pollution.
2. Start a Student-Run Recycling Club
When the teachers, students, and custodians at our school noticed the
great amount of paper being thrown away every day, we knew it was time
to make a change. Hill School has now been recycling its paper since the
winter of 2008. Each classroom, copy room, and office has at least one
recycling bin, and there are bins in the gym, music room, art room,
cafeteria, and media center. 
To make students active participants in the recycling process, Lora
Herbert, an awesome 4th grade teacher at my school, started a student
recycling club three years ago. During lunch each day, recycling club
members are assigned to collect and empty the recycling bins in specific
rooms. Through the use of posters, word-of-mouth, and “commercials” on
our televised morning announcements, the students in this club have made
the staff and students at Hill School well aware of what materials can
and cannot be recycled. We are pros at recycling our construction paper,
catalogs, envelopes, scrap paper, and more, thanks to our recycling
club.
3. Recycle Newspapers & Magazines to Create Fabulous Art Projects
Another way to support your school’s “going green” effort is to get
your art teacher involved. The art teacher at my school, Katie Hosbach,
planned neat projects using entirely recycled materials.
For
instance, some students created musical rumba shakers from drinkable
yogurt containers donated by families in the school community. Using
strips of outdated newspaper, they made a hard papier-mâché shell around
the yogurt containers. Students filled the maracas with rice, beans,
peas, or popcorn and decorated them with paint. 
Some 2nd grade students made cityscapes out of donated magazines after
looking at examples of cityscapes done by famous artists. Students
understood that since they are reusing the magazines for an art project
instead of using brand new construction paper, they were helping reduce
the amount of paper being used and recycled, which saves energy.
4. Adopt an Endangered Animal
Our students brought in coins in order to raise money to adopt an
endangered animal from the Detroit Zoo. As coins were collected,
students learned about the two endangered animals they would choose from
— a chimpanzee or a Grevy's zebra
— on the morning announcements and through student-created PowerPoint
presentations that ran on TV during lunch time in the cafeteria. After
enough money was raised, each classroom voted on which animal to adopt,
and the Grevy’s zebra won. Our school purchased a stuffed plush Grevy's
zebra, which sits on display in the main hallway for everyone to see.
The class that raised the most money chose the name for the zebra,
Pablo. To adopt an endangered animal at your school, contact your local
zoo or visit the World Wildlife Fund's site. 
5. Host a Solar Cookout
Our school hosted a solar-powered cookout last fall. Parent
volunteers created solar-powered “ovens” made out of cardboard boxes,
aluminum foil, and some rocks and sticks. Before the cookout, we
publicized the event in the school’s weekly newsletter and on our daily
morning TV announcements, explaining the idea and the process behind the
solar cookout. The whole school was treated to a delicious dessert of
s'mores cooked by the sun. It was a big hit and a great example of the
power of natural energy. Visit Disney's Spoonful to learn how to make solar s'mores.
6. Take an Environmentally Informative Field Trip
Field trips are another great way to help your students become more environmentally conscious.
Alternative Energy Plant:
If you have an alternative energy plant near your school, take a trip
to learn about renewable resources. In 2009, renewable energy, from
sources like the sun, wind, and water, only provided about eight percent
of the energy used in the United States. However, the use of renewable
fuels has begun to increase in recent years due to the high price of oil
and natural gas. Visit Energy Kids to read more about renewable energy and find games, activities, and lesson plans to supplement your curriculum.
Local Landfill:
If your students think that trash just disappears, then it's time for a
trip to a landfill. While students are plugging their noses, teachers
can point out all the items in the landfill that don't have to be there —
cardboard, newspapers, old food, perfectly good-looking furniture, old
computers, etc. Explain how everything gets crushed down and squished
together, so that even things that would normally decompose, like food,
have a hard time decomposing. If you are like me and are not ready to
take an actual field trip to a landfill, you can find many videos about
how landfills work by doing a Google search. For instance, I found one
for kids at the Wisconsin Department of Natural Resources site.
Recycling Center:
For a similar (and slightly less stinky) field trip, take your class on
a tour of a local recycling center. Students can see firsthand how
items are separated and sent off on different conveyor belts. They learn
how plastics will be turned into park benches and new decks and how
paper will be shredded, mashed, and processed into new paper.
Alternatively, take your class on a photo tour that shows where trash goes after it leaves the house. You might also visit Recycle City, a fun, interactive Web site to help your students learn more about recycling and protecting our environment.
Organic Farm: Most
students do not grow any vegetables at home and do not raise their own
animals, so going to a farm is a real eye-opener. They can see where the
eggs really come from, and that it's not the grocery store. Workers at
the farm can show them how the carrots grow underground, and are pulled
up, cleaned, and cut up. Most farms also have a u-pick-fruit area where
students can pick blueberries, strawberries, or blackberries.
7. Organic Composting
Last year, master composters from SOCWA
came to our school to teach 4th grade students about organic
composting. Equipment was brought in and students were split into groups
to experience the art of making organic compost. A large bucket was
filled with each group’s compost material and stored in the classroom
for the remainder of the winter. Each student had an observation packet
for monthly compost mixing days. In the spring, students made their last
observation of their organic compost and spread it outside to help the
flowers grow. (Thanks to Liz Waters, an awesome 4th grade teacher at my
school, for sharing this idea.)
8. Create a Birdhouse Habitat Around Your Playground
The
Wolf Cub Scout group made up of students at my school constructed
birdhouses as a den project and created a birdhouse habitat around our
playground. The birdhouses provide nesting space in the birds’
increasingly threatened habitat. An increased bird population is not
only pleasant for the eyes and ears, but is also important to our
ecosystem. Birds scavenge wastes, pollinate plants, and search for food
in the garden. They help our garden habitat by eating greenflies,
caterpillars, and snails: a huge benefit for the organic gardener.
9. Go Paperless
Our school is trying to reduce our use of resources by going paperless.
Starting this year, our school’s weekly newsletter (and most classroom
newsletters) are sent home via an email blast instead of being printed
out and copied for all 334 students. Following the success of the
emailed newsletter, our school started using the email blast to
disseminate other information to parents, including field trip
information, fan-outs, PTO meeting updates, volunteer requests, etc.,
saving even more paper. Also, when it is necessary to send home a hard
copy of a note, only the youngest students or only one student of a
family gets a copy.

Penyebab Rusaknya HardDisk
Penyebab Rusaknya HardDisk
HardDisk merupakan hardware penyimpanan data yang utama pada komputer. Tanpa harddisk, komputer tidak dapat digunakan secera optimal, karena tampilannya hanya tulisan-tulisan berwarna hitam putih.
HardDisk merupakan hardware yang sensitif. Ada beberapa hal yang menyebabkan rusaknya harddisk. Namun yang paling parah adalah matinya aliran listrik secara mendadak, yaitu:
- Mati lampu. Solusinya adalah dengan memakai adaptor khusus yang dapat menyimpan listrik untuk beberapa menit. Jadi saat mati lampu terjadi, komputer tetap menyala dan masih ada kesempatan untuk mematikan komputer dengan aman.
- Reset. Sebagian orang berfikir bahwa menekan tombol resset pada CPU adalah hal kecil, padahal ini sangat berbahaya bagi harddisk. Alasannya ketika jarum harddisk sedang bekerja, maka posisinya sedang berada di tengah-tengah piringan harddisk. Dan jika kita menekan tombol resset, maka si jarum tersebut akan serentak bergerak ke tepi piringan dan meninggalkan bekas goresan maka terjadilah badsector. Oleh karena itu, jangan asal-asalan menekan tombol reset.
Sekedar tips seandainya komputer hang dan tidak ada jalan lain selain menekan tombol reset. Tunggulah sampai lampu harddisk (biasanya yang berwarna merah) mati, walau pun nyalanya berkedip-kedip, tekanlah tombol resset saat lampu harddisk sedang mati/tidak menyala.
Mudah-mudahan tulisan ini bermanfaat. Bagi anda yang mau menambahkan atau menyanggah tips diatas, saya tunggu di kotak komentar. Terima kasih.
