Remarks by President Obama on the “Educate to Innovate” Campaign and Science Teaching and Mentoring Awards, January 6, 2010

To all the teachers who are here, as President, I am just thrilled to welcome you, teachers and mentors, to the White House, because I believe so strongly in the work that you do. And as I mentioned to some of you, because I’ve got two girls upstairs with math tests coming up, I figure that a little extra help from the best of the best couldn’t hurt. So you’re going to have assignments after this. (Laughter.) These awards were not free. (Laughter.)

We are here today to honor teachers and mentors like Barb who are upholding their responsibility not just to the young people who they teach but to our country by inspiring and educating a new generation in math and science. But we’re also here because this responsibility can’t be theirs alone. All of us have a role to play in building an education system that is worthy of our children and ready to help us seize the opportunities and meet the challenges of the 21st century.

Whether it’s improving our health or harnessing clean energy, protecting our security or succeeding in the global economy, our future depends on reaffirming America’s role as the world’s engine of scientific discovery and technological innovation. And that leadership tomorrow depends on how we educate our students today, especially in math, science, technology, and engineering.

But despite the importance of education in these subjects, we have to admit we are right now being outpaced by our competitors. One assessment shows American 15-year-olds now ranked 21st in science and 25th in math when compared to their peers around the world. Think about that — 21st and 25th. That’s not acceptable. And year after year the gap between the number of teachers we have and the number of teachers we need in these areas is widening. The shortfall is projected to climb past a quarter of a million teachers in the next five years — and that gap is most pronounced in predominately poor and minority schools.

And meanwhile, other nations are stepping up — a fact that was plain to see when I visited Asia at the end of last year. The President of South Korea and I were having lunch, and I asked him, what’s the biggest education challenge that you have? He told me his biggest challenge in education wasn’t budget holes, it wasn’t crumbling schools — it was that the parents were too demanding. (Laughter.) He’s had to import thousands of foreign teachers because parents insisted on English language training in elementary school. The mayor of Shanghai, China — a city of over 20 million people — told me that even in such a large city, they had no problem recruiting teachers in whatever subject, but particularly math and science, because teaching is revered and the pay scales are comparable to professions like doctors.

President Obama Speaks on Getting Students Excited About Science and Engineering

The President announces the “Educate to Innovate” initiative, a campaign to get students excited about pursuing careers in science, technology, engineering and mathematics. Quotes from President Obama from his speech – (see webcast above):

“As President, I believe that robotics can inspire young people to pursue science and engineering.”

“Now the hard truth is that for decades we’ve been losing ground. One assessment shows American 15-year-olds now rank 21st in science and 25th in math when compared to their peers around the world.”

“And today, I’m announcing that we’re going to have an annual science fair at the White House with the winners of national competitions in science and technology. If you win the NCAA championship, you come to the White House. Well, if you’re a young person and you’ve produced the best experiment or design, the best hardware or software, you ought to be recognized for that achievement, too. Scientists and engineers ought to stand side by side with athletes and entertainers as role models, and here at the White House we’re going to lead by example. We’re going to show young people how cool science can be.”

“improving education in math and science is about producing engineers and researchers and scientists and innovators who are going to help transform our economy and our lives for the better.”

Learning Design of Experiments with Paper Helicopters

Paper helicopter stairwell dropPhoto showing the helicopter test track by Brad

Dr. George E.P. Box wrote a great paper on Teaching Engineers Experimental Design With a Paper Helicopter that can be used to learn principles of experimental design, including – conditions for validity of experimentation, randomization, blocking, the use of factorial and fractional factorial designs and the management of experimentation.

I ran across an interesting blog post on a class learning these principles today – Brad’s Hella-Copter:

For our statistics class, we have been working hard on a Design of Experiments project that optimizes a paper helicopter with respect to hang time an accuracy of a decent down a stairwell.

We were to design a helicopter that would drop 3 stories down within the 2ft gap between flights of stairs.

[design of experiments is] very powerful when you have lots of variables (ie. paper type, helicopter blade length, blade width, body height, body width, paperclip weights, etc) and not a lot of time to vary each one individually. If we were to individually change each variable one at a time, we would have made over 256 different helicopters. Instead we built 16, tested them, and got a feel for which variables were most important. We then focused on these important variables for design improvement through further testing and optimization.

Test it Out, Experiment by They Might Be Giants

Put It to the Test is one of the songs on the great new Album and animated DVD from They Might Be Giants: Here Comes Science.

Are you sure that thing is true, or did someone just tell it to you.
Come up with a test. Test it out.
Find a way to show what would happen if you were incorrect. Test it out.
A fact is just a fantasy unless it can be checked.
Make a test. Test it out.

A fun song on fundamentals of experimenting to the scientific method.

Lego Mindstorms Robots Solving: Sudoku and Rubik’s Cube

LEGO Mindstorms Rubik’s Cube Solver

Tilted Twister solves Rubik’s cube fully automatically.
Just place the scrambled cube on Tilted Twister’s turntable. An ultrasonic sensor detects its presence and starts to read the colors of the cube faces using a light sensor. The robot turns and tilts the cube in order to read all the faces. It then calculates a solution and executes the moves by turning, tilting and twisting the cube.

The challenge was to build the robot using only the Lego Mindstorms NXT Retail-kit. And to make it completely independent, without need of being connected to a PC.
The Lego Mindstorms NXT Retail-kit contains three servo motors and four sensors (touch, light, ultrasonic and sound). How should I build the robot using only these items?
After a lot of experimenting I came up with a solution – If I tilted the whole robot, it would be possible for it to tilt the cube using only one motor, leaving the other two motors for turning the cube and for positioning the light sensor. Thus Tilted Twister.

Scanning the cube: 1 minute
Calculating a solution: 20 – 40 seconds
Executing the moves: 1 – 5 minutes. Average 4.5 minutes (60 faceturns)
Average total time: 6 minutes

Very cool. Related book: Building Robots With Lego Mindstorms

Young Engineers Take LEGO ‘Bots For a Swim

Young Engineers Take LEGO ‘Bots For a Swim

The Stevens Institute of Technology hosts this competition annually on its campus here, gathering students earlier this month from more than 40 middle and high schools to pit their designs against one another in kiddie pools on the banks of the Hudson River. In dozens of such competitions around the world, young people build, program and drive vehicles made of Legos and other more rugged materials. These events are a bid to interest a new generation in careers in engineering and robotics, and they are becoming more sophisticated.

Upping the ante this year, Build IT introduced Lego’s NXT programmable control box. At least one student on each team learned to program the NXT. The programmer determined which of the vehicle’s propellers would spin and in which direction when the driver moved the levers.

Holding up the device, Abigail Symons from Lincoln Park Middle School demonstrated her work. “Those are the controls and those are the touch sensors and this is a rotation sensor,” she said. She had never used such technology before she joined the team.

“I thought I was going to be bad at it because I wasn’t sure if the right motor would go with the right propeller, but in the end I got it so, it was good,” she said.

The Build IT program is funded by a $1.2 million grant from the National Science Foundation with further funding by the Motorola Foundation. It is one facet in the NSF’s scheme to entice students into future careers in engineering and other sciences.

4 and 8 Year Old Sisters Impress with Squeak

Young programmers win big

XtremeApps is a competition based in Singapore where competitors program computer applications from scratch.

Armed with just the basics in the Squeak programming language, as well as encouragement – but no help – from mum and dad, the Chan sisters came up with an application called Health Fairies.

It is an interactive, educational story with an anti-smoking message: The main protaganist is a beautiful young girl who loses her youth, and good looks, because she puffs away like there’s no tomorrow.

The sisters took the bulk of the June holidays to complete their entry. They had to come up with the storyline, draw the characters, and write programs that animated the characters, among other things.

Their effort paid off: Health Fairies landed a merit award in the junior category of the contest, beating 68 other contestants, mostly 11 and 12 year olds.

Presidential Awards for Excellence in Science, Mathematics and Engineering Mentoring

Project Exploration wins a presidential award for science education

This week, Project Exploration received one of 22 Presidential Awards for Excellence in Science, Mathematics and Engineering Mentoring, a prize that carries a $10,000 grant and an award ceremony this fall at the White House.

So Project Exploration started summer and after-school programs to expose students underrepresented in the sciences, primarily girls and minorities, to scientists and their real-life work. Students design research projects and test them in the field, or work summers at museums demonstrating science to young children.

One group of girls is currently tracking coyotes in Yellowstone National Park, Lyon said. “Over time, they find they’re making discoveries not just about science but about themselves,” she said.

SUNY Plattsburgh professor earns presidential honor

Her students have been working to unlock the mysteries of the past as they analyze the DNA from skeletons of ancient Maya. They are trying to answer questions like did the disorder Beta-Thalassemia, a type of anemia, really exist in the Americas before Columbus set sail? What accounts for differences in burial among some of the Maya? Were some from more aristocratic family lines? What route did the Maya take across the Bering Strait? And are there other Native American tribes that share a common ancestry?

Her students are also working to unlock mysteries of the present, studying a newly found gene that exists in paramecium (single-celled organisms) that may tell them more about evolution.

Others have just completed a joint project, working with Elwess, Adjunct Lecturer Sandra Latourelle and members of the college’s psychology department – SUNY Distinguished Teaching Professor Jeanne Ryan and Professor William Tooke. They searched for links between an individual’s genes, aggressive behavior and the ratio of one finger to another. Their results will be released soon.

This sort of work has led to SUNY Plattsburgh undergraduates winning top honors for poster presentations at both the National Association of Biology Teachers and International Sigma Xi conferences four years in a row. In addition, many of Elwess’ students have also gone on to pursue higher degrees in the field, being accepted into schools like Yale and the University of Oregon.

President Obama today named more than 100 science, math, and engineering teachers and mentors as recipients of two prestigious Presidential Awards for Excellence. The educators will receive their awards in the Fall at a White House ceremony.

The Presidential Award for Excellence in Science, Mathematics and Engineering Mentoring, awarded each year to individuals or organizations, recognizes the crucial role that mentoring plays in the academic and personal development of students studying science or engineering and who belong to minorities that are underrepresented in those fields. By offering their time, encouragement and expertise to these students, mentors help ensure that the next generation of scientists and engineers will better reflect the diversity of the United States.

Botball 2009 Finals

Webcast of the double elimination rounds of the Botball 2009 competition of the winning Alcott Middle School Botball team. Norman teens win robotics contest:

The challenge of building the robot and seeing it do what it’s programmed to do is very exciting, said Goree, 14. “I like figuring out what’s wrong with the robots, fixing them and then seeing them work after you fix them,” he said.

The team was shocked, excited and proud of their first-place finish, they said. “Almost all the teams we played against were high school teams, so that was pretty exciting for us, beating high schoolers,” Goree said.

Teen diagnoses her own disease in science class

Teen diagnoses her own disease in science class

Her doctors, no matter how hard they tried, couldn’t figure out the cause of Jessica’s abdominal distress. Then one day in January, Terry, 18, figured it out on her own.

In her Advanced Placement high school science class, she was looking under the microscope at slides of her own intestinal tissue — slides her pathologist had said were completely normal — and spotted an area of inflamed tissue called a granuloma, a clear indication that she had Crohn’s disease.

“It’s weird I had to solve my own medical problem,” Terry told CNN affiliate KOMO in Seattle, Washington. “There were just no answers anywhere. … I was always sick.”

Crohn’s disease is often misdiagnosed or diagnosed very late, says Dr. Corey Siegel, director of the Inflammatory Bowel Disease Center at Dartmouth-Hitchcock Medical Center in Lebanon, New Hampshire. “Granulomas are oftentimes very hard to find and not always even present at all,” Siegel said. “I commend Jessica for her meticulous work.”

Rutgers Initiative to Help Disadvantaged Children

Praise for ambitious Rutgers initiative to help disadvantaged youths

It’s been a year since Rutgers University launched one of the country’s most ambitious education experiments, a campaign to change the fortunes of urban teenagers

Adolescents, their parents and public school administrators uniformly praise the Future Scholars Program. Last June, the initiative started 200 disadvantaged seventh-graders along a five-year path of summer workshops, tutoring, social support and cultural outings. Their reward if they keep a B average and meet other requirements: a full ride to Rutgers.

The Rutgers Future Scholars Program is not targeting science, it focuses on all academic areas.

The goal of the Rutgers Future Scholars program is to increase the numbers of academically ambitious high school graduates who come from low-income backgrounds, help them meet the standards to be admitted to colleges and universities, and then provide tuition funding to those who are admitted and choose to attend Rutgers University.

By improving educational opportunities, in general, more disadvantaged children will have the opportunity to become scientists and engineers. They are highlighting what recent high school graduates from the Camden school are doing, such as Aspiring Physician, Stem Cell Researcher, Rutgers-Camden Student

Most students don’t conduct stem-cell research and sit on a national board with a $3 million budget. Tej Nuthulaganti isn’t like most students.

After earning his undergraduate degree in biology from Rutgers-Camden in 2007, Tej is on track to earn his graduate degree in biology this May, thanks to the five-year combined bachelor and master degree program in biology at Rutgers-Camden.

For the past two years the 2003 graduate of Highland High School has been working with Daniel Shain, an associate professor of biology at Rutgers-Camden and one of the nation’s leading experts on leech research. Nuthulaganti has furthered Shain’s research on identifying key genes that are pivotal in the stem cell formation in the leech, which gives a simple model system for more complicated research. Their research could be beneficial in the early detection of cancerous cells.

In addition to presenting his research at major conferences, including one at the University of California-Berkeley, Nuthulaganti has also made sure that his fellow students who are considering careers in medicine also have a forum to ask questions and think deeply about what kinds of doctors they’d like to be.

There are many great programs underway that are aimed at improving education performance. And this seems like another good effort.

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.

The Engineer Girl website has done a smart thing and posted all the essays online. It is a simple act but one so often other organizations fail to do in similar circumstances.

Teen Tackles Centuries-old Numbers challenge

teen tackles centuries-old numbers challenge

A 16-year-old Iraqi immigrant in central Sweden has single-handedly figured out a formula with Bernoulli numbers that is normally reserved for much more seasoned mathematicians, earning him praise from professors at prestigious Uppsala University.

While it’s not the first time that someone has shown such Bernoulli number relationships, it’s highly unusual for a first year high school student to make his way through the complicated calculations, according to Uppsala University senior maths lecturer Lars-Åke Lindahl. “He’s a very clever guy,” Lindahl told The Local.

“What he did isn’t necessarily new, but it is quite remarkable for a first year high school student to take on these types of problems all on his own. It’s certainly an achievement.”

Altoumaimi plans to continue studying advanced math and physics over the summer. “I wanted to be a researcher in physics or mathematics; I really like those subjects. But I have to get better at English and social science,” he told Falu-Kuriren.

Intel Science and Engineering Fair 2009 Webcasts

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.

The Great Sunflower Project

photo of sunflower (Helianthus Annuus Taiyo)Sunflower photo from WikiMedia – Helianthus Annuus ‘Taiyo’

The Great Sunflower Project provides a way for you to engage in the ongoing study of bees and colony collapse disorder. The study uses the annual Lemon Queen sunflowers (Helianthus annuus), that can be grown in a pot on a deck or patio or in a garden (and they will send you seeds).

How do bees make fruits and vegetables?

Bees help flowers make seeds and fruits. Bees go to flowers in your garden to find pollen (the powder on the flower) and nectar which is a sweet liquid. Flowers are really just big signs advertising to bees that there is pollen or nectar available – though sometimes a flower will cheat and have nothing! The markings on a flower guide the bee right into where the pollen or nectar is.

All flowers have pollen. Bees gather pollen to feed their babies which start as eggs and then grow into larvae. It’s the larvae that eat the pollen. Bees use the nectar for energy. When a bee goes to a flower in your garden to get nectar or pollen, they usually pick up pollen from the male part of the flower which is called an anther. When they travel to the next flower looking for food, they move some of that pollen to the female part of the next plant which is called a stigma. Most flowers need pollen to make seeds and fruits.

After landing on the female part, the stigma, the pollen grows down the stigma until it finds an unfertilized seed which is called an ovary. Inside the ovary, a cell from the pollen joins up with cells from the ovary and a seed is born! For many of our garden plants, the only way for them to start a new plant is by growing from a seed Fruits are just the parts of the plants that have the seeds. Some fruits are what we think of as fruits when we are in the grocery store like apples and oranges. Other fruits are vegetables like tomatoes and cucumbers and peppers.
