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.

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.

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.

Germany’s shortage of engineers has become so acute that some of its leading companies are turning to kindergartens to guarantee future supplies.

Groups such as Siemens and Bosch are among hundreds of companies giving materials and money to kindergartens to try to interest children as young as three in technology and science.

Many European countries from Switzerland to Spain suffer shortages of graduates. But the problem is especially acute in Germany, renowned as a land of engineering. German companies have 95,000 vacancies for engineers and only about 40,000 are trained, according to the engineers’ association.

“It is a new development in that we have seen we need to start very early with children. Starting at school is not good enough - we need to help them to understand as early as possible how things work,” said Maria Schumm-Tschauder, head of Siemens’ Generation21 education programme.
…
Siemens has provided about 3,000 “discovery boxes” filled with science experiments for three- to six-year-olds to kindergartens throughout Germany, at a cost to the company of €500 (£395) a box. It also trains kindergarten teachers on how to use them as well as providing similar boxes around the world to pre-schools from China and South Africa to Ireland and Colombia.

The Science Barge is a prototype, sustainable urban farm and environmental education center. It is the only fully functioning demonstration of renewable energy supporting sustainable food production in New York City. The Science Barge grows tomatoes, cucumbers, and lettuce with zero net carbon emissions, zero chemical pesticides, and zero runoff.

From May to October 2007, the Science Barge hosted over 3,000 schoolchildren from all five New York boroughs as well as surrounding counties as part of our environmental education program. In addition, over 6,000 adult visitors visited the facility along with press from around the world.

Limited growing space means growing upwards, with stacked pots for strawberries, and vines that grow up to the ceiling and are then folded over to grow back down. Instead of using pesticides, pests are kept in check using ladybugs, parasitic wasps, and other predators as needed. Environmentally friendly substrates such as rice husks, coconut shells, and Earth Stone (recycled glass), are used to aerate the root systems for the plants.

Most fascinating of all was the Aquaponic system for providing nutrients to the plants using catfish. Nutrients from the plants and worms feed the catfish, who produce nitrogen-rich waste, which feeds the plants. Tilapia were originally used, but eventually replaced with catfish, which were better suited to the climate. The result of all this effort is a bounty of fresh fruits and vegetables given out to all the children who visit the barge.

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.

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.

As fat people have an abundance of fat tissue, the natural assumption is that fat people have more fat cells, or ‘adipocytes’. That’s only part of the story - it turns out that overweight and obese people not only have a surplus of fat cells, they have larger ones too.
…
During adulthood, about 8% of fat cells die every year only to be replaced by new ones. As a result, adults have a constant number of fat cells, even those who lose masses of weight. Instead, it’s changes in the volume of fat cells that causes body weight to rise and fall.

we couldn’t have a clearer indication of the importance of childhood as a window for preventing obesity and the chronic diseases affected by it - cancer, heart disease, diabetes and more.

The message is especially stark following the recent Foresight report, which estimated that if current trends are left unchecked, by 2050 a quarter of all UK children under the age of 16 will be obese. The knowledge that their fat cell count will then be set for life makes the cost of inaction even higher. Fortunately, it seems that the UK Government is taking appropriate steps and recently pledged over a third of a billion pounds on a concerted strategy to tackle childhood obesity.

For the 2007 awards, 99 middle school and high school math and science teachers are receiving this recognition. In the citation from the president, winners are commended “for embodying excellence in teaching, for devotion to the learning needs of the students, and for upholding the high standards that exemplify American education at its finest.”

Each winner receives a $10,000 award from NSF, as well as a trip for two to Washington, D.C., for a week of celebratory events and professional development activities.

Among the activities during that week are a day with scientists and science educators at NSF; meetings with members of Congress and federal agency leadership; and a reception and dinner at the U.S. Department of State featuring guest speaker Dorothy Metcalf-Lindenburger, a NASA Astronaut-Mission Specialist.
