Seventh-grader shines with solar cell research

Yuan worked on his project for the past two years with the encouragement of his science teacher Susan Duncan; support of his parents Gang Yuan and Zhiming Mei; and counsel of professional mentors Professor Chunfei Li of Portland State University’s Center for Nanofabrication and Electron Microscopy, Fred Li of Applied Materials Inc. and Professor Shaofan Li of the Department of Civil Engineering at the University of California – Berkeley.

“He is our youngest fellow in science that we’ve ever had,” Moessner said. “He is really spectacular. “His project will really make a difference in advancing the technology of solar cells. You would never know he’s 12 looking at the quality of his work.”

Beaverton boy lauded for solar cell invention

there have been many questions about the research by William Yuan. Some have even questioned whether he copied the research of others and claimed it as his own. That is far from the case. Yuan fully documented all of his sources and never tried to imply that he invented the 3D solar cell. He did create a new type of 3D solar cell that works for visible and UV light

William Yuan was awarded a 2008 Davidson Fellow award

In his project, “High Efficient 3-Dimensional Nanotube Solar Cell for Visible and UV Light,” William invented a novel solar panel that enables light absorption from visible to ultraviolet light. He designed carbon nanotubes to overcome the barriers of electron movement, doubling the light-electricity conversion efficiency. William also developed a model for solar towers and a computer program to simulate and optimize the tower parameters. His optimized design provides 500 times more light absorption than commercially-available solar cells and nine times more than the cutting-edge, three-dimensional solar cell.

2008 Innovation Generation Grants

The Motorola Foundation today announced the recipients of its 2008 Innovation Generation grants, which provide $4 million to 92 K-12 education programs across the country.

Eileen Sweeney, director of the Motorola Foundation: “Building a diverse pipeline of critical thinkers, skilled scientists and engineers is a by-product of our efforts that not only will benefit Motorola and our industry, but it also will support a sustainable workforce and bolster the country’s competitive advantage in the global, knowledge-based economy.”

According to the Bureau of Labor Statistics, Strengthening Education: Meeting the Challenge of a Changing World, jobs requiring science, engineering or technical training will increase 24 percent between 2004 and 2014 to 6.3 million. The disparity between the growing demand for critical thinkers and the country’s ability to adequately prepare students to fill these jobs has been widening for decades. The lack of skilled graduates in these fields poses a significant threat to sustained U.S. competitiveness in the global, knowledge-intensive economy.

Examples of this year’s grant recipients include:

* American Indian Science and Engineering Society (AISES) – The AISES National American Indian Science and Engineering Fair and Expo inspires American Indian and Alaska Native students from all 50 states to pursue their interest in science and engineering through in-person and virtual presentations of research, access to role models and mentors, and hands-on demonstrations of scientific and engineering innovations across industries.

* Edheads in Columbus, Ohio – A highly interactive website for middle school girls interested in engineering design will be used nationally by schools and after-school programs.

* Rochester Institute of Technology – TechGirlz weeklong camp for girls who are deaf and hard-of-hearing and entering seventh, eighth or ninth grades fosters their long-term interest in STEM and enhances their awareness of the opportunities available to them in these disciplines in higher education.

* University of Central Florida – My Sports Pulse engages Florida middle school and high school students in a youth mobile learning initiative that imparts science and technology concepts through interactive sports games and tests.

Alumni Return to Redesign High School Engineering Classes

Prince George’s County High School Alumni Return to Redesign Classes

Cressman joined nine fellow graduates of the elite science and technology magnet program every day for six weeks to create top-flight engineering courses for high school students. The class at the Greenbelt, Maryland, school will teach the latest in computer programming and drafting with software used by college professors and professional engineers. And since engineering teachers can be hard to find, the curriculum is designed to be taught by a non-expert.
…
All freshman in the science and technology magnet program are already required to take two introductory engineering classes, but the curricula for those classes were originally designed in 1976. “There has been some revamping through the years, but we knew we needed a major overhaul. Things have changed so much,” explains Jane Hemelt, coordinator of the science and technology program, which serves about 900 of the school’s 2,700 students. The problem was that there wasn’t an easy way to get the expertise to fix it.

Hemelt talked about the problem with Rocco Mennella, a mathematics professor at Prince George’s Community College and Catholic University who teaches science and math at Roosevelt. For several years, Mennella had been recruiting Roosevelt graduates as tutors for his summer precalculus class, and he told Hemelt that his recruits—who were science, math, and engineering majors—might serve double duty by redesigning the engineering curriculum.

Mennella’s college recruits came from Caltech, MIT, Brown, Johns Hopkins, Georgia Tech, and the University of Maryland, where they have been exposed to some of the best science and engineering teachers in the country. In addition, Cressman contacted about 80 engineering professors at universities and colleges around the country to find out what they would like their incoming students to know; almost 50 responded.
…
For example, all agreed that the classes should focus on the practical aspects of engineering, including computer-aided design and computer programming, while exposing the high school students to electrical, civil, and mechanical engineering. But the curriculum designers also wanted their younger peers to have fun while learning, so they put in many hours on computers creating lessons that would challenge students to redesign the Taj Mahal, build an SUV, or guide a robot.
…
Eleanor Roosevelt High School will test some of the modules as part of other classes this fall, which will reach 30 students or more, and the team hopes to roll out the other classes full time in coming years. The Prince George’s school district’s other two science magnet schools, Oxon Hill and Charles Flowers, also plan to use the curriculum. But Mennella and Hemelt hope it will spread even wider, including to schools that don’t specialize in science and math. Those schools might just use parts of the curriculum, or spread a semester-long class out over a year. “Who knows, this could become a model for the state and maybe a model for the country,” Hemelt says.

I am looking into how people can see the curricula, and any other material that may be available.

Tinker School: Engineering Camp

NPR had a nice story on kids taking risks (a compliment our post from a couple days ago: Kids Need Adventurous Play) Camp Offers Kids A Chance To Play With Fire. Tinkering School gives kids a chance to make real things they use (boats, motorized bikes, bristle bots…). Their blog is awesome.

The Tinkering School offers an exploratory curriculum designed to help kids – ages 7 to 17 – learn how to build things. By providing a collaborative environment in which to explore basic and advanced building techniques and principles, we strive to create a school where we all learn by fooling around. All activities are hands-on, supervised, and at least partly improvisational.
…
Parents/guardians will be expected to complete the big scary liability waiver.
…
Tinkering School is taught primarily by me, Gever Tulley, aided of course by my indispensable wife Julie Spiegler and the inimitable Robyn Orr. By day, I am a Senior Computer Scientist at Adobe, writer, and practicing sculptor…

I started the Tinkering School because it’s the kind of thing I would like to have been able to go to myself.

I wish I could go. Related: National Underwater Robotics Challenge – Science Toys You Can Make With Your Kids – La Vida Robot – Technology and Fun in the Classroom

Students at Powhatan Engineering Camp

Students attend Powhatan’s first-ever engineering camp

The 28 students participating in the first-ever Powhatan County Schools engineering camp spent eight days doing hands-on activities like building model amusement park rides and suspension bridges, and taking field trips to see engineering in action. They visited the Richmond Times Dispatch’s production facility, where they observed robots shuttling stacks of paper back and forth, and the Watkins Center, where they observed engineers at work on a construction site.

The group even enjoyed a presentation from a NASA engineer, who spoke of his experience working on the Mars rover.

These engineering camps help kids enjoy their naturally inquisitive minds – which unfortunately they don’t get to do often enough.

Science and the City: Science Barge

Science and the City is (among other things) an excellent podcast series from the New York Academy of Science. The latest podcast discusses the science barge project we posted about earlier. They discuss looking at commercially viable urban farms (on rooftops in NYC) and the establishing educational gardens at schools.

See the Curious Cat Science and Engineering Podcast Directory for some great resources for podcasts. Don’t miss the naked scientists from the BBC.

Beloit College: Girls and Women in Science

Girls and Women in Science at Beloit College in Wisconsin:

sixth grade girls, along with their teachers and parents. This award winning conference encourages the exploration of science and mathematics by middle school girls through two days of experiments, activities, and interaction with science professionals. The girls, teachers, and parents will work with Beloit College faculty, students, and alumnae.

Girls getting into science

Eaton said the 24 girls participating will be able to take an active role in the laboratories. It’s critical the girls are encouraged and get the chance to increase their risk-taking abilities without boys.

The problem is, Eaton said, that sixth-grade girls’ interest in science starts dwindling and boys start becoming more dominant. “The boys take over the hands-on projects and the girls take notes,” Eaton said. “Boys will answer a question more authoritatively. Girls pose answers as a question. They are not as confident in their answers.”

To help foster activity among girls, the weekend conference also offers several workshops for parents and teachers. The workshops teach adults what they are doing to discourage girls and how they can learn to encourage them more.

US Navy Sponsored Technology Summer Camp

US Navy plants a new seed of future engineers

When 14-year-old Dayne Savory first heard about a summer camp on technology in suburban Maryland, he had no idea that he would become so interested in science and engineering.

“Even though engineering was not one of my first options, now I will consider it. After attending this program I realized that I was able to do this,” Long Island resident Savory said.

Worried about the steep decline in U.S. science and engineering graduates, U.S. institutions such as the Navy and the NAVSEA — the command in charge of building, buying and maintaining the Navy’s ships- are promoting technology camps and competitions around the country. They’re doing it through partnerships with a growing number of associations such as the nonprofit Seat Pleasant, Md.-based Patriots Technology Training Center.
…
The students built underwater robots and held a competition on July 3 at Prince George’s Sports and Learning Complex.

Thurman Jones, president of the Patriots Technology Training Center, said that the number of participants grows every year. To support this summer’s edition -as well as other programs organized by the Patriots Center — the U.S. Navy and the NAVSEA provided more than $100,000 worth of in cash, technical equipment and volunteers, according to Jones.

Fold.it – the Protein Folding Game

Foldit is a revolutionary new computer game enabling you to contribute to important scientific research. This is another awesome combination of technology, distributed problem solving, science education…

Essentially the game works by allowing the person to make some decisions then the computer runs through some processes to determine the result of those decisions. It seems the human insight of what might work provides an advantage to computers trying to calculate solutions on their own. Then the results are compared to the other individuals working on the same protein folding problem and the efforts are ranked.

This level of interaction is very cool. SETI@home, Rosetta@home and the like are useful tools to tap the computing resources of millions on the internet. But the use of human expertise really makes fold.it special. And you can’t help but learn by playing. In addition, if you are successful you can gain some scientific credit for your participation in new discoveries.

The site includes some excellent educational material on proteins and related material. What is a protein:

Proteins are the workhorses in every cell of every living thing. Your body is made up of trillions of cells, of all different kinds: muscle cells, brain cells, blood cells, and more. Inside those cells, proteins are allowing your body to do what it does: break down food to power your muscles, send signals through your brain that control the body, and transport nutrients through your blood. Proteins come in thousands of different varieties, but they all have a lot in common. For instance, they’re made of the same stuff: every protein consists of a long chain of joined-together amino acids.
…
structure specifies the function of the protein. For example, a protein that breaks down glucose so the cell can use the energy stored in the sugar will have a shape that recognizes the glucose and binds to it (like a lock and key) and chemically reactive amino acids that will react with the glucose and break it down to release the energy.
…
Proteins are involved in almost all of the processes going on inside your body: they break down food to power your muscles, send signals through your brain that control the body, and transport nutrients through your blood. Many proteins act as enzymes, meaning they catalyze (speed up) chemical reactions that wouldn’t take place otherwise. But other proteins power muscle contractions, or act as chemical messages inside the body, or hundreds of other things.

Engaging the YouTube Generation in Hands-on Science

Cherlyn Anderson is one of eight Einstein Fellows spending this academic year at NSF. In her other life, Anderson is an eighth-grade science teacher in South Carolina. She has used an experiment involving Mentos candy and Diet Coke as a teaching tool. The accompanying video offers a demonstration of the experiment, and discusses its benefits for eighth-grade science students.

Follow the link for a webcast. Somewhat ironically the NSF headline mentions YouTube but fails to take advantage of one of the things that has made YouTube (and others sharing videos: TED…) so successful. The ability to embed the videos on web sites, blog posts… The technical quality of the video is very nice (more pixels than YouTube videos).
