American High School


American High School features a model student led recycling program to divert paper and CRV material from the waste stream.  Funds from the recycling program are channeled back into campus beautification efforts including tree planting.  Students in science classes regularly participate in activities such as paper making and labs that investigate materials separation techniques used in single stream recycling systems.  American High School hosts monthly meetings of FIERCE- FremontIans Enabling Real Change in the Environment- a student group representing each of Fremont's five high schools that work together to plan community events and organize service projects such as the establishment of community gardens.

Glass Recycling Experiments Help Teach Chemistry

"I want students to go beyond just collecting materials for recycling," notes Sykes, "I want them to actually learn how stuff is made."

With a grant from the Altamont Education Advisory Board, Sykes was able to purchase a glass firing kiln, ceramic molds, and other start up supplies to begin experimenting with glass remanufacturing.

"We did get some advice from the lead engineer and glass chemists from the factory, but at this point, we are truly experimenting to see what works."

Students are collecting different types and colors of glass, breaking them into course, medium and fine grade frit, arranging a variety of firing schedules, and tracking the results.

"Glass has to cool down slowly or it will de-vitrify," explains Pavritra Ravishankar- one of Sykes's students. "Luckily, we have a programmable kiln, so we can raise the temperature quickly, then specify a cool down schedule to avoid crystalizing the glass."

Sykes hopes to one day create enough tiles for large projects and expand to using shaped molds for creating glass jewlery. Students apply kiln-wash to the mold to prevent glass from fusing to the mold itself, then add glass and any additives.

So far, students have discovered that brown glass melts and fuses the easiest compared to green and clear glass. Medium/course frit produces a nice pebbled texture, and clear glass can be colored by adding various chemical salts to the firing molds.

Pavritra shared the school's results on March 17th at the International Zero Waste Youth Convergence in San Francisco. She and her peers hope to have the process understood and functioning by the end of May so they can share and sell their products at the Maker Faire.

Food Scrap Diversion Waste Stations

With support from an Altamont Education Advisory Board Grant, teacher Candy Sykes was able to purchase lightweight diversion stations for the rotunda. "It was important to our custodial staff that the stations be easy to move so they can sweep and polish the large area. We were able to find stations that are lightweight and seem durable."

Sykes and her fellow science teachers plan to set up a service program through their classes where students help monitor the bins and educate their peers about the proper placement of compostable materials.

The bins were assembled and installed by the school's Recycling Team on Friday, March 15th.

Recycling Team Keeps it Clean and Green


Recycling is Fun!Recycling is Fun!American High School's Recycling Team is a group of students dedicated to keeping the school clean and green.

The team collects and sorts recyclable materials, redeems bottles and cans for funding used on environmental projects and scholarships and seeks ways to expand and improve its efforts.

The Recycling team volunteers are frequently joined by 9th graders from Ms. Wheaton's Biology class who are able to earn extra credit points for helping the environment.

Washing the BinsWashing the Bins

Students meet near the school's science wing every Friday afternoon to process the reclaimed materials, regularly filling large clear bags full of crushed plastic bottles and aluminum cans.

Students also wash and maintain the recycling bins and signs around campus.

 

American High School Garden Update


WeedingWeedingFruit trees are in bloom, and students are busy at work in the American High School garden which has received many updates in the last few months.

Recent additions to the garden include a compost bin made from reclaimed wooden pallets, new gravel for garden pathways, and the beginnings of a stone floor for the outdoor gazebo classroom.

Stone FloorStone FloorVolunteer Ed Sykes led a group of students in weed pulling on a recent Friday afternoon to help prepare for re-mulching and new plantings.  "We're a bit overgrown right now," admited Ed, "but the students are showing a lot of enthusiasm for getting things in shape for the spring."

In addition to spring planting, upcoming projects include expanded sheet mulching using reclaimed cardboard and the installation of a wooden and bamboo fence to create a visual barrier with the parking lot.

Imagining New Green Machines


Smog Cloud CondenserSmog Cloud CondenserWhat if a machine could convert smog to energy? What if that energy powered the machine to clean up more smog? Sisters Cynthia and Katie Wu from American High School in Fremont imagined such a machine, called a "Smog Cloud Condenser" as part of the Chabot Space & Science Center's Green Machine Design Challenge.

The initiative challenges visitors to imagine new technologies that improve the environment.  Visitors sketch out their designs on graph paper and submit them for consideration.  Museum staff then review all submissions, choosing some to be featured in Bill Nye's Climate Lab, the museum's top floor exhibit.

The sisters were inspired to make their machine to address global warming challenges, undaunted by the fact that others have not yet solved the problem. Katie points out, "This technology doesn't exist yet, but what would happen is smog goes into the tube and condenses and through some process turns into something good." Cynthia adds, "It collects the smog in the sky and turns it into energy. It condenses the pollution in the smog cloud and recycles it for energy."

Katie and Cynthia's design was chosen by Chabot's staff to be made into a 3D model as inspiration to other visitors. Artist Todd Kundla took up the challenge of fabricating the design. According to Kundla, "The Cloud Condenser captured my attention with its uniquely shaped structures as well as its alluring concept. Something about the 'not knowing' all of the details of how this invention worked was curiously enjoyable. Freed from the science of the machine and concentrating on its aesthetic was liberating."

Tamara Schwarz, Chabot's Senior Manager of Experience Design notes, "inventions happen in the mind before they ever happen in real life.  We hope to inspire creativity and encourage our visitors to dream up new solutions to challenges that haven't yet been met."
