(牛顿中文学校支教工作小组, 周津平执笔)
伴随着新年的钟声和春节的欢庆,牛顿中文学校的支教活动也已经进入了第六个年头的募捐及筹集活动的繁忙阶段。 此时, 支教小组欣然闻知,我们赞助的中国贫困学生不仅如愿完成高中学业, 有许多孩子还顺利的考上了大学, 踏上了丰富人生经历为社会做出贡献的新的人生旅程。
过去五年中,牛顿中文学校先后支持了中国四川大桥中学,江西昌江一中和云南永胜中学三个学校近百名贫困学生。 对于这些受赞助的学生来说,我们给予的资助数额虽小,却是足以改变他们整个人生的巨大能源。我们带给每个受赞助的贫困学生不仅是学费,更多的是牛顿中文学校全体师生以及广大在美华人对他们的关注和爱心,让他们感受到的是温暖和希望。因为如果没有这些支持,他们许多人就会因贫困而不能完成高中学业,更谈不上追求高等教育的梦想。对于在美国的华人孩子来讲,上大学就算不是天经地义,也几乎是自然而然的人生道路。更多的家庭只是在为孩子上什么大学,怎么上更好的大学而操心。可是,对于支教活动赞助的中国学生的家庭来讲,因为贫穷,支付不起仅几百元学费而使孩子缀学放弃高中学业却是难以避免的严酷现实。牛顿中文学校的支持就是给予这些孩子们一丝阳光,一个机会,一分希望,一度梦想。
我们看到这些从中国反馈来的信息,心中无比的激动和高兴。这份硕果属于牛顿中文学校全体家长,老师, 同学,校行政和董事会。

AP Chemistry Exam on May 7, 2012, Monday

On Exam Day

What to Bring

  • Several sharpened No. 2 pencils with erasers for all responses on your multiple-choice answer sheet.
  • Pens with black or dark blue ink for completing areas on the exam booklet covers and for free-response questions in most exams.
  • Your six-digit school code. Home-schooled students will be given a code at the time of the exam.
  • A watch.
  • AP-approved calculatorwith the necessary capabilities if you are taking the AP Calculus, Chemistry, Physics or Statistics Exams.
  • A ruler or straightedge only if you’re taking an AP Physics Exam.
  • A government-issued or school-issued photo ID if you do not attend the school where you are taking the exam.
  • Your Social Security number* for identification purposes (optional). If you provide your number, it will appear on your AP score report.
  • If applicable, your SSD Student Accommodation Letter, which verifies that you have been approved for extended time or another testing accommodation.

What Not to Bring

  • Cell phones, digital cameras, personal digital assistants (PDAs), BlackBerry smartphones, Bluetooth-enabled devices, MP3 players, email/messaging devices, or any other electronic or communication devices.
  • Books, compasses, mechanical pencils, correction fluid, dictionaries, highlighters,**notes or colored pencils.**
  • Scratch paper; notes can be made on portions of the exam booklets.
  • Watches that beep or have an alarm.
  • Portable listening devices** or portable recording devices (even with headphones) or photographic equipment.
  • Computers.**
  • Clothing with subject-related information.
  • Food or drink.**

* Some colleges and universities use Social Security numbers as student identifiers when assigning AP credit or advanced placement for qualifying AP scores. While the College Board does not require you to provide your Social Security number, you may want to check with the college or university where you are sending scores to see if they prefer for you to provide a Social Security number on your AP Exam answer sheet.

**Unless this has been preapproved as an accommodation by the College Board Services for Students with Disabilities office prior to the exam date.

Topics covered

The exam covers common chemistry topics, including:

The exam

The annual AP Chemistry examination, which was administered on May 2, 2011, is divided into two major sections (multiple-choice questions and free response essays). The two sections are composed of 75 multiple-choice questions and 6 free-response essay prompts that require the authoring of chemical equations, solution of problems, and development of thoughtful essays in response to hypothetical scenarios.

  • Section I, the multiple-choice portion, does not allow the use of a calculator, nor does it provide any additional reference material, other than a periodic table. 90 minutes are allotted for the completion of Section I. Section I covers the breadth of the curriculum.
  • Section II, the free response section, is divided into two sections: Part A, requiring the completion of three problems, and Part B, containing three problems. Part A, lasting 55 minutes, allows the use of calculators, while Part B, lasting 40 minutes, does not. The first problem in Part A concerns equilibrium related to solubility, acids and bases, or pressure/concentration. The first question of Part B is a chemical equation question in which 3 scenarios are presented and the student is required to work all 3 scenarios, authoring a balanced net ionic chemical equation for each scenario and answer questions about the equations and scenarios. If time permits, students may edit their responses from Part A during the time allotted for responding to Part B, though without the use of a calculator. The student must complete all six questions.

While the use of calculators is prohibited during Section I and Section II Part B, a periodic table, a list of selected standard reduction potentials, and two pages of equations and conventions are available for use during the entirety of Section II.

Chemistry-Focused Contest Launched

Entries must be received by 7 PM PDT on April 1.
Organizations hope to inspire young female scientists with contest named for Rosalind Franklin
Department: Education | Collection: Women in Chemistry
Keywords: science

Middle school and high school students have an opportunity to compete for cash prizes in a new chemistry-focused contest. Science Buddies—a nonprofit organization that provides science fair resources for students, teachers, and parents—and the Astellas USA Foundation have teamed up to sponsor the Rosalind Franklin Chemistry Contest.

Although the contest is open to all U.S. students in grades six to 12, the organizers especially hope to attract aspiring young female scientists. With that goal in mind, the organizers named the contest after Franklin, the crystallographer whose X-ray diffraction data helped lead to the identification of the double-helical structure of DNA.

In naming the contest, “we were looking for a female chemist who had achieved great things,” says Courtney Corda, vice president at Science Buddies. “There are many to choose from, but what’s interesting about Rosalind Franklin is that she probably did not get as much recognition—at least in her lifetime—as she probably deserved.”

The main focus at Science Buddies is helping students who are working on projects for science competitions—any competition. “We’re kind of Switzerland—that is, neutral—when it comes to which competition,” Corda says. And in the new contest, students are welcome to let their projects pull double duty. “It’s perfectly fine for them to send us a project they did for another competition,” Corda says.

Students can come up with their own project, but if they need inspiration, they can start with an idea from the Science Buddies website. The project ideas vary in complexity, but each one provides a scaffold on which students can build their own research. Students need to come up with their own testable hypothesis. Last year, chemistry was the most popular area on the Science Buddies website, which had 12 million visitors, Corda says. “Lots of kids out there have a budding interest in chemistry,” Corda says. “We want to nurture that.”

Jeffrey I. Seeman, visiting senior research scholar at the University of Richmond and creator of the Archimedes Initiative, a website focused on improving science literacy through high school science fairs, says: “Having a science fair focused exclusively on chemistry may well encourage students to do a project in that field rather than in another discipline. What could be better for those of us in the broad field of the molecular sciences than to have more youth interested in joining us?”

Corda encourages chemists who are interested in mentoring students on science fair projects to contact Science Buddies about its expert forum.

For the contest, students must complete a display board describing their projects, and the judges—staff scientists at Science Buddies—will assess entries on the basis of creativity, scientific thought, thoroughness, skill, and clarity of presentation. Entries must be received by 7 PM PDT on April 1.

The top submissions will receive cash awards. The winning high school students will each receive $500; the top middle school students will receive $250. In each grade range, one boy and one girl will be selected. Winners will be announced in May.
