Brighton eighth-grader rewarded for her love for science

Thirteen-year-old Kate Yuhas, who plans to be an environmental engineer someday, has loved science since she was little.
…
Yuhas received an honorable mention certificate from the National Academy of Engineering’s EngineerGirl! Web site Imagine That! Engineering Innovation Essay Contest for her essay on a tanning booth that helps people produce vitamin D. “My whole life I’ve been interested in science,” Yuhas said. “I really like helping the environment and eating organic.”

“Kate has a talent for science and math, and she’s won medals at Science Olympiad,” said her mom, Johanna, who coaches the team. “Kate has always had science-themed parties. My husband and I are both engineers, and we talk a lot about science at home.”

The essay contest asked participants to consider one of three images on the EngineerGirl! site and to discuss its potential purposes and functions using engineering creativity.

Read Kate’s essay: The Cure to Vitamin D Deficiency

What can help prevent MS, high blood pressure, and several autoimmune diseases? The answer to that question would be Vitamin D, which you can get in three ways: food, supplements, and the sun. 70 percent of Americans lack adequate amounts of Vitamin D. The reason is that people just don’t get enough sun. That’s why my invention would be so helpful. It is a special tanning booth that only gives out the specific amount of UVB rays, the type of UV rays that is needed to produce Vitamin D, which you need.

Intel Science and Engineering Fair 2009 Webcasts

Posted on May 17, 2009  Comments (3)

Tara Adiseshan, 14, of Charlottesville, Virginia; Li Boynton, 17, of Houston; and Olivia Schwob, 16, of Boston were selected from 1,563 young scientists from 56 countries, regions and territories for their commitment to innovation and science. Each received a $50,000 scholarship from the Intel Foundation.

In the webcast, Tara Adiseshan, talks about her project studying the evolutionary ties between nematodes (parasites) and sweat bees. She identified and classified the evolutionary relationships between sweat bees and the nematodes (microscopic worms) that live inside them. Tara was able to prove that because the two have such ecologically intimate relationships, they also have an evolutionary relationship. That is to say, if one species evolves, the other will follow.

Li Boynton developed a biosensor from bioluminescent bacteria (a living organism that gives off light) to detect the presence of contaminants in public water. Li’s biosensor is cheaper and easier to use than current biosensors, and she hopes it can be used in developing countries to reduce water toxicity.

Olivia Schwob isolated a gene that can be used to improve the intelligence of a worm. The results could help us better understand how humans learn and even prevent, treat and cure mental disabilities in the future.

In addition to the three $50,000 top winners, more than 500 Intel International Science and Engineering Fair participants received scholarships and prizes for their groundbreaking work. Intel awards included 19 “Best of Category” winners who each received a $5,000 Intel scholarship and a new laptop. In total, nearly $4 million is scholarships and awards were provided.

High School Students to Intern in Engineering

Posted on December 27, 2008  Comments (1)

Pasco high school students to work as interns in engineering

Five area manufacturers announced Tuesday that they will join forces with River Ridge High’s new engineering career academy, which opens in fall 2009, to provide students work opportunities while they are still in school.
…
“The idea is to start a program of internships starting in the 10th grade,” said Wahnish, who presents the idea to the Florida Engineering Society today.

By the time graduation rolls around, students will have had three six-week apprenticeships and received industry certifications in computer-assisted design and other applications. They also will be ready to go to work or enroll in a university program. Even those who go to work still would attend college at least two days a week.

High School Inventor Teams @ MIT

Posted on December 11, 2008  Comments (7)
Lemelson-MIT InvenTeams is a national grants initiative of the Lemelson-MIT Program to foster inventiveness among high school students. The webcast above shows a high school team presenting a project they completed to create a solution to provide clean water. This stuff is great. I love appropriate technology. I love seeing kids think and create effective solutions to real problems. This is how you get kids to learn – not boring classes (at least kids like me).

The students are passing on the project to students at their school to continue to work on. MIT TechTV has many more presentation by other InvenTeams. InvenTeams and MIT deserve a great deal of credit for creating such great learning opportunities and great solutions for the world.

InvenTeams composed of high school students, teachers and mentors are asked to collaboratively identify a problem that they want to solve, research the problem, and then develop a prototype invention as an in-class or extracurricular project. Grants of up to $10,000 support each team’s efforts. InvenTeams are encouraged to work with community partners, specifically the potential beneficiaries of their invention.

National Girls Collaborative Project for STEM

Posted on November 22, 2008  Comments (0)

The National Girls Collaborative Project for science, technology, engineering, and mathematics (STEM) collaborates with those seeking to increase the participation of girls in STEM feeder activities. The goal is to encourage girls to pursue careers in science, technology, engineering, and math.

Collaboration as a Means to Building Capacity: Results and Future Directions of the National Girls Collaborative Project:

The purpose of the NGCP is to extend the capacity, impact, and sustainability of
existing and evolving girl-serving STEM projects and programs. The NGCP is structured to bring organizations together to compare needs and resources, to share information, and to plan strategically to expand STEM–related opportunities for girls.
…
Although we are still refining it, the NGCP collaborative model has shown its effectiveness through increased collaboration and minigrant projects with sustained results. As we have described, the success to date of the NGCP in developing collaborations has been demonstrated via data from the collaboration rubric, mini-grant reports, and metrics that show how collaborative activities have increased over the duration of the NGCP projects. As NGCP expands over the next few years to provide regional collaboratives across the entire United States and Puerto Rico, we will continue our assessment of its impact and hope to be able to report its influence on building capacity to attract and retain girls in STEM.

I support programs encouraging STEM activities for girls – and boys. NSF data shows for 2005 shows women outnumbered men in undergraduate degree in science and engineering. For post-graduate degrees men still outnumbering women but that gap has been reducing and seems like it will continue to. And the representations in the workplace seem poised to continue to show a reducing number of men and increasing number of women. Engineering is an example of an area with far more men than women graduating – the imbalance is equivalent to the imbalance the other way for psychology.

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.

High School Student Isolates Microbe that Eats Plastic

Posted on May 24, 2008  Comments (2)

WCI student isolates microbe that lunches on plastic bags

Daniel Burd’s project won the top prize at the Canada-Wide Science Fair in Ottawa. He came back with a long list of awards, including a $10,000 prize, a $20,000 scholarship, and recognition that he has found a practical way to help the environment.
…
First, he ground plastic bags into a powder. Next, he used ordinary household chemicals, yeast and tap water to create a solution that would encourage microbe growth. To that, he added the plastic powder and dirt. Then the solution sat in a shaker at 30 degrees.

After three months of upping the concentration of plastic-eating microbes, Burd filtered out the remaining plastic powder and put his bacterial culture into three flasks with strips of plastic cut from grocery bags. As a control, he also added plastic to flasks containing boiled and therefore dead bacterial culture.

Six weeks later, he weighed the strips of plastic. The control strips were the same. But the ones that had been in the live bacterial culture weighed an average of 17 per cent less.
…
The inputs are cheap, maintaining the required temperature takes little energy because microbes produce heat as they work, and the only outputs are water and tiny levels of carbon dioxide — each microbe produces only 0.01 per cent of its own infinitesimal weight in carbon dioxide, said Burd.

“This is a huge, huge step forward . . . We’re using nature to solve a man-made problem.” Burd would like to take his project further and see it be used. He plans to study science at university, but in the meantime he’s busy with things such as student council, sports and music.
