Spider Silk 2014 Methods and Materials

 

A. Method of assembling the extractor.

The Silk Extractor, one of the 2 U.S. Patented devices under the Forman School’s Rainforest Project, is key to the process of the silk extraction. This highly effective device scratch-built by Forman Students, has only three main parts consisting of the box, crank and the “wheel”  This portable and compact piece of equipment is very easy to assemble. To start the assembly of the Silk Extract the handle (window crank) is attached to the rear of the box by screwing it in place. Once secure, the “wheel” consisting of eight cut arrow shaft’s placed in a circle (25.4cm).   Once both crank and “wheel” is secure, the Silk Extractor is now ready for the extraction process.

B.  Method for extraction

The method for the extraction of the Nephila Clavipes spider is also under the same protection of the US Patent of the Silk Extractor.  Before the extraction process begins, the three members of the Spider Silk team are given each individual jobs which are vital to the operation. Such jobs include, the handler which has the role of transporting the spider to and  from its web, and uses the “Hand-over-Hand” method to give the spider the sensation of falling; The Crank operator, which is responsible for counting the number of rotations used to silk each individual spider, and the operation of the Silk Extractor; the final job is the Computer Operator, who is responsible for keeping track of all the data throughout the expedition.
To start the extraction, the Spider Handler must carefully remove the Golden Orb Weaver spider from its web. Once the spider is situated on the arrow shafts, the spider  should lay its sticky disc. In order to extract the silk from the spider, the Crank Operator and the Spider Handler must coordinate strongly together because each spider behaves differently. The spider goes into the handlers hand. Then, the handler uses the “hand-over-hand” method to silk the spider. (This method is when the handler places their hands in a tilted down position in order to simulate the sensation of falling for the spider. The silk that is being extracted is the dragline silk. The silk comes out of the Major Ampullate gland. If executed properly the spider should produce silk.) At the same time, the Crank Operator begins the process of spinning with one hand, while the Computer Operator records the data being received.

Once the spider has finished silking, the Spider Handler returns the spider back to its web. After each spider, the following data is recorded; Number of rotations, length of silk, Color of silk, number of strands, Time of extraction, and Weather variables.

C. Methods for feeding

To ensure that variables are close to accurate as possible, the Spider Silk team has developed a method for feeding the spiders. This is vital the silk extracting process and shows that farming these spiders is easy so that a local farmer can perform the extraction technique.  In order to attract these insect, a black light is placed inside of a mesh laundry hamper. Once the light is in place, a dog collar is then positioned over the opening. When fully assembled, the Feeding Ring is hung low to the ground. Within 30 minutes the Feeding Ring is remove from the tree. With the insects caught, feed spiders with insects.  We mostly feed them moths. take insects and throw them into webs.     

D. Method for Logger Pro

In order to use the Logger Pro application. The application is opened. To start the data graph, the recorder types the strength and the elasticity of the silk. X is going to be strength and elasticity is going to by Y. based upon our field results, the recorder types in the data, into Logger Pro and makes a graph.

E. Method for Employing Local Families.
Employing 2 local families to test what quantity of silk they can get.

F: Method for Light Meter

Going to be using a light meter to look at the amount of lumens that are hitting hte web and going to be measuring by Klux. this will be used to keep track of lumens hitting each web, and coordinating color of silk.

Thank You Glacier Computer

Spider silk has received a new computer from Glacier Computer. Glacier lent us their T510K for when we trek down to the rainforest. This bad boy is loaded with Microsoft Windows Xp, can withstand temperatures from -4 to 113 fahrenheit and its shock absorption up to 40 G. We will be using the computer to input our data and will really help us when we are down in Costa Rica. A Big thank you to Glacier Computer! Much Appreciated!

Spider Silk 2013-2014

spider silk — the strongest natural fiber in the world. It is well-suited for many uses like medical sutures and gloves, bullet proof vests, and more. For this, the school has been granted two US patents!

Scientists used to think that the Golden Orb Weaver spider was cannibalistic and not farmable. So companies are spending millions of dollars bio-engineering their spider silk. But our research has found little cannibalistic tendencies and in fact, they prefer to live in tight colonies. We have been able to collect their silk at a fraction of the cost.

This is the future of technology. And the Forman School’s Rainforest Project, the only High School in the country with this intense of a program, is on the brink of making history.

Goals:

1. To get as much spider silk as possible.
2. To figure out when and why the silk is most strong.
3. Make a cottage industry for local ranchers abutting rainforest land.

Spider Team Has Silked a Mile!

The spider team reported yesterday that they have already gathered a MILE of spider silk – the strongest natural fiber.  The highest strength they have measured is 6.4 Newtowns.

Spider Silk Team

The silk from the Nephila clavipes spider is groundbreaking in many ways but nothing is more impressive than its strength; it isthe strongest natural fiber in the world. Its possible uses range from medical sutures to bulletproof vests. Most importantly, it’s a sustainable source of income for the people of Costa Rica as opposed to cattleranching, which will only last for a matter of years. The three of us along with our fearless leader Wendy Welshans plan to confirm our research concerning the connections between different environmental factors that would help us find the strongest silk possible.Spider Silk Team
