Young Engineers Build Bridges with Spaghetti

Young engineers build bridges with spaghetti:

Proving that spaghetti is not just for dinner, the students of Johns Hopkins University’s Engineering Innovation summer program used the noodles to build intricate, miniature bridges and then wrecked them — all in the name of science. On Friday afternoon, the eight high school students participating in the competition pitted their engineering know-how against one another to see whose bridge could hold the most weight before splintering into pieces. The competition closed out four weeks of study under the summer program, which was taught by Muhammad Kehnemouyi, a full-time physics professor at Montgomery College, and Fred Katiraie, a full-time math professor at Montgomery College.

The last team to go consisted of Sruti Bharat, 17, of California, Rohan Bhale, 15, of Olney, and Justin Yin, 17, of Wheaton. The group put weight after weight on the bridge and attached another chain to add more weights, but the bridge remained in one piece.

After adding all the weights available to them, Katiraie ran into another room to retrieve more. The team’s bridge held almost 60 times its actual weight before splintering.

Creating a Nation of Wimps

I certainly don’t know if this is true, or the even the consensus of the scientific thought today, but it happens to feel right to me. Not exactly a scientific conclusion but there you go. From, Psychology Today says, A Nation of Wimps:

Parents are going to ludicrous lengths to take the bumps out of life for their children. However, parental hyperconcern has the net effect of making kids more fragile; that may be why they’re breaking down in record numbers.

In his now-famous studies of how children’s temperaments play out, Harvard psychologist Jerome Kagan has shown unequivocally that what creates anxious children is parents hovering and protecting them from stressful experiences. About 20 percent of babies are born with a high-strung temperament. They can be spotted even in the womb; they have fast heartbeats. Their nervous systems are innately programmed to be overexcitable in response to stimulation, constantly sending out false alarms about what is dangerous.

As infants and children this group experiences stress in situations most kids find unthreatening, and they may go through childhood and even adulthood fearful of unfamiliar people and events, withdrawn and shy. At school age they become cautious, quiet and introverted. Left to their own devices they grow up shrinking from social encounters. They lack confidence around others. They’re easily influenced by others. They are sitting ducks for bullies. And they are on the path to depression.

Well for whatever it is worth I think the article is interesting (I am not exactly sure about the introversion part that doesn’t seem to have a strong ring of truth but I do think it is better to experience real failure and overcome it than be too sheltered and without that you don’t learn confidence you just are kept from having to feel discomfort as long as the adults protect you…) even if it is just because it attacks something I find a bit annoying the increasing tendency to act like mistakes are not mistakes, failure to achieve an objective doesn’t matter, kids should not be challenged… I don’t think coddling is a good way to create confident people that function well in the world.

People need to learn that things often don’t work the way you might think or hope, things are not fair, things can hurt you, you can loose things you care about, if you make a decision you have to live with the consequences… It is not that hard to understand these things. Kids might well prefer to just be handed everything they want without an risk or effort on their part. But I believe they will learn how to cope and take pride in actually doing good stuff. Which will work much better than trying to convince them they should take pride in something even they can probably tell is fake, coddling. Of course I don’t have any kids either so my opinions are not only not put into practice by me. Oh well go read the article if you are interested.

Evolution at Work - Blue Moon Butterfly

Butterfly shows evolution at work

The tropical Blue Moon butterfly has developed a way of fighting back against parasitic bacteria. Six years ago, males accounted for just 1% of the Blue Moon population on two islands in the South Pacific. But by last year, the butterflies had developed a gene to keep the bacteria in check and male numbers were up to about 40% of the population.

Scientists believe the comeback is due to “suppressor” genes that control the Wolbachia bacteria that is passed down from the mother and kills the male embryos before they hatch. “To my knowledge, this is the fastest evolutionary change that has ever been observed,” said Sylvain Charlat, of University College London, whose study appears in the journal Science.

“We’re witnessing an evolutionary arms race between the parasite and the host. This strengthens the view that parasites can be major drivers in evolution,” Mr Charlat said.

It makes a great deal of sense that evolution would have such bursts under the right conditions. This seems an nearly perfect example of such conditions - if males can be produced they are going to have a large opening to reproduce and rapidly pass on a new tool to fight the bacteria. The University of California - Berkeley has a good site on understanding evolution (with lesson plans for k-16 and information for anyone interested in science).

Intel International Science and Engineering Fair 2007

Top 3 students - Intel ISEF 2007

Can These Kids Save American Science?

Jose Manuel Otero realized that science was his goal in 1996, when he went to ISEF with a project on filtering diesel from water using charcoal that he made from leaves and grass. Otero, the son of Spanish immigrants who never finished high school, took first place in the Connecticut state fair and went on to the internationals, winning third place in his division. “I didn’t know I wanted to be a scientist until I got to ISEF,” he says.

Where students in previous generations built robots in their basements or sampled pond water in the local park, the majority of today’s winning projects showcase research done in a lab under the supervision of a mentor, an academic at a university or corporate research institute. Students get their own portion of the lab’s investigation. If they discover anything of significance, they might be rewarded as a co-author of a paper the professor submits to a journal, or they might share in a patent that the lab takes out on their work. One team project from Stony Brook’s summer program on detecting individual cancer cells by how hard or soft they are is up for a patent and has been submitted to the journal Science.

The top three winners of the ISEF receive a $50,000 scholarship and $4 million in cash and scholarships are awarded. Related: Intel ISEF Awards 2006 - Science Fair Project on Bacterial Growth on Packaged Salads - Amber’s Science Talent Search Blog - Science Fair Directory

Einstein Fellowship for Teachers

Ruth McDonald selected for Einstein Fellowship program:

“As a middle school science teacher, I love science, but I’m no engineering expert,” said McDonald, who has also taught math, social studies, and language arts during her career. “But I can bring in the experts using technology.” Her innovative use of technology - handhelds, laptops, videoconferencing with engineers and scientists - was among the elements leading to her selection.

The fellowship program offers current public or private elementary and secondary mathematics, technology, and science classroom teachers with “demonstrated excellence in teaching” an opportunity to make an impact in the national public policy arena. Fellowships enhance understanding, communication, and cooperation between legislative and executive branches and the science, mathematics, and technology education community.

McDonald’s 11-month fellowship assignment is with the National Science Foundation. She will receive a stipend for her work from September 2007 through July 2008. “It’s not really a job,” she explained. “It’s a professional growth and development opportunity, with a focus on science, math, and technology. I’m excited about the resources this experience can bring to our district.”

McDonald, who said the district’s willingness to let her take time off to pursue the opportunity “shows how much they value teacher development and achievement,” said she plans to return to LCSD following the fellowship. Until then, she will provide insight into her experience via blogging and videoconferencing, continuing the use of technology that helped land her in Washington D.C. in the first place.

Computer Game and Real World Education

Planning ahead: UW game teaches kids, mixes virtual, real worlds

14 middle schoolers have been participating in “Urban Science” and working in a computer lab at Wendt Library on the UW’s engineering campus. They spend their summer mornings immersed for four weeks in a highly sophisticated computer game that takes them deep into a world where the lines between fantasy and reality are deliberately blurry.

The students work for a fictitious firm called Urban Design Associates, are assigned the title of planner, carry business cards and do field research in actual neighborhoods, armed with digital cameras and notebooks, under the guidance of graduate students in the educational psychology department. As part of the game, the grad students are known as planning consultants.

I like the real world and technology interaction for education. I believe getting kids involved with real world problems is a good way to get them interested in learning.

National Underwater Robotics Challenge

See the National Underwater Robotics Challenge web site for information on the event in Arizona June 8th through 10th. They offer a remote underwater vehicle kit for $250.

The ROV-IN-A-BOX is intended to help get teams involved that are new to underwater robotics. Buy purchasing this kit, it helps put an inexperienced team, or a team with young students like elementary school kids, into a comfort zone to allow them to take on the Underwater Challenge. It reduces the stress, time and resources needed to acquire all the parts to complete an ROV for the competition. The kit can also be used by a more mature team as a starting point for the ROV they may want to build.

There will be a live video stream June 9 at 8pm MST and will continue to until about 2am MST June 10. The video will come from both the ROV and in the pool with event cameras in and around the submarine. Once the video has been processed and mixed poolside by Arizona State University’s Applied Learning Technologies Institute, it will then be channeled to Chandler High School’s television studio, where it will be broadcast to a view gallery and simultaneously sent to a server at ASU where it will be webcast to the world.

Awesome Cat Cam

CatCam - photo of the famous cat photographer CatCam - cat photographer on the run CatCam - cat photographer get picture of another cat

subscribe to Curious Cat Engineering Blog

CatCam by Juergen Perthold - this great project involved taking a digital camera and some additional equipment to create a camera that his cat wore around his neck which took pictures every 3 minutes. The pictures are great. The cat got photos of several other cats and seemed to like cars.

See more cool gadgets, See our other popular posts and our cat related posts.

Sometimes I have some challenging ideas, or crazy like some other people would say. This time I thought about our cat who is the whole day out, returning sometimes hungry sometimes not, sometimes with traces of fights, sometimes he stay also the night out. When he finally returns, I wonder where he was and what he did during his day. This brought me to the idea to equip the cat with a camera. The plan was to put a little camera around his neck which takes every few minutes a picture. After he is returning, the camera would show his day.

The VistaQuest made it very easy for me, because it is able to supply my circuit also if switched off. This is because of an internal DC/DC converter which boosts the voltage from the 1.5V battery to 3.3V. The DC/DC converter is always working because of the internal SRAM which holds the pictures. I just had to hook the microcontroller to the internal camera supply.

Well, I thought the hardest part is done by developing the software and soldering the controller board. But it is more the housing to protect the camera. You can not imagine what kind of requirements have to be fulfilled if you want to equip your cat with a camera. I built a small housing out of plastic plates and put it on the collar of the cat for evaluation purpose. This housing was last seen as the cat walked out of the door… Probably the wires I used for attaching were not strong enough. Or someone released the cat from the interesting looking piece.

For the second try I used the plastic package of a child toy (Kinderueberraschung), put a stone in it for loading it with some weight and attached it again to the cat collar. This time the part returned - dirty and scratched outside, water inside. What the hell is the cat doing !? This raised the requirements for the camera protective housing a lot

Big moment no. 1: attach the collar with the camera to the cat. The reaction was not very happy but finally accepted. Reality check passed :-)

This is my favorite home engineering project. The concept is great. The explanation of the technology is great. The adjustment to real life situations is great. The end result (the photos) is great. This wins the non-existent Curious Cat Cool Contraption award. If someone doesn’t start selling prefabricated cat cameras I will be very surprised (if I was more enterprising I would do it myself). Maybe J. Perthold will, in any event he should inspire many to try making their own.

Open Source Education Curricula

Curriki Global Education and Learning Community

Our mission is to improve education around the world by empowering teachers, students and parents with user-created, open source curricula, and it’s all free! We believe that access to knowledge and learning tools is a basic right of every child. Our goal is to make curricula and learning resources available to everyone.

Another promising looking effort, though they do need to improving the editing of content. They also need to add tools to make it easy to find the content others have found most beneficial. And they should improve the accessibility of the content - all of it should be available using a browser (now some content is presented only as zipped files, some are word documents…). 200 science and 150 math documents are available now including: Big Cats and Intro to Electricity . The site includes content hosted itself and links to content hosted on other sites.

High School Students Interest in Computer Programing

Interesting post on Keeping students interested in Computer Science by an 11th grader:

Most students coming into a high school computer science course are expecting to be able to program mind blowing 3D games within a semester. When most find out that they won’t be able to come close to doing so within their single course of computer science class, most bid adieu to it and move on. Students learn that playing video games is a very small subset of computer science, and find this fact discouraging. This is where many students also lose a lot of interest in computer science. They don’t care about sorting through arrays or lists of data, or coming up with algorithms to solve problems. For this reason, a balance must be found between teaching computer science concepts, and applying the learned concepts in an engaging manner.

Very true. Engaging students, as with all teaching, is critical to making learning not just tolerable but fun.

Lego Autopilot First Flight

Chris Anderson continues his progress with the sub $1,000 autonomous flight vehicle (using lego mindstorms at the core). He has created a site to track the progress and provide information resources to others: DIY Drones. Very cool.

Lego autopilot first flight:

My kids and I actually had the first successful test flight of the sub-$1,000 UAV two weekends ago, but I haven’t had time to edit the video properly until now. The good news is that a) it didn’t crash, and b) it works. We tested stabilization, autonomous navigation (only using compass headings this time, although GPS is in the works), and the real-time video downlink. Everything worked well enough that we’re able to see what we have to improve, which is the definition of a successful test.

The main aim of this project is to both make the world’s cheapest full-featured UAV and the first one designed to be within the reach of high school and below kids, as a platform for an aerial robotics contest. Like the Lego FIRST league, but in the air.

International Student Collaboration

Contest links high school students worldwide:

During the school year, 58 teams of American students coupled with students from China, India and Japan tackled technological solutions to global warming. They chatted online, divided jobs based on skill, consulted with advisers, and in the final grueling weeks, wrote a professional business plan.

“The most important goal is to engage U.S. students in international collaboration using science and technology,” said David Gibson, executive director of the Global Challenge and a research assistant professor in computer sciences at the University of Vermont. The idea for the contest came to management consultant Craig DeLuca two years ago as one of his clients planned to outsource design and manufacturing, and his community in Stowe considered putting off buying science textbooks.

“I’ve got to do something so that our kids have a shot in the global economy,” he said then. He launched the contest in Vermont, and last fall it was awarded a $900,000 National Science Foundation Grant and expanded worldwide. Winners will be announced in June.

Not only does the contest encourage interaction between students across the globe to solve problems, it also exposes them to opportunities in science, technology, engineering and math, Gibson said. “We need projects like this across the nation, so we can scoop these kids up because schools don’t do it for them,” he said.

Science Topics Explained on One Page

Seed Magazine has one page crib sheets on science topics as guides for living in the 21st century. For example, String Theory:

To unite the seemingly incompatible worlds of the very large and the very small, physicists propose string theory, a model of the universe in which tiny strings vibrate in more than three dimensions. This Cribsheet covers the basics of string theory: what it says, why we think it might give us a unified theory of physics, and whether experiment supports it. In addition, we tell you how the strings are shaped and why string theory may not be the final “theory of everything.”

Other topics: stem cells, climate change, avian flu, hybrid cars, nuclear power, hurricanes, extinction and the elements. Great stuff.

Home Experiments: Quantum Erasing

Do your own experiment on quantum erasing - Quantum Erasing in the Home (for instructions). From the accompanying article, A Do-It-Yourself Quantum Eraser:

The light patterns that you will see if you conduct the experiment successfully can be accounted for by considering the light to be a classical wave, with no quantum mechanics involved. So in that respect the experiment is a cheat and falls short of fully demonstrating the quantum nature of the effect.

Nevertheless, the individual photons that make up the light wave are indeed doing the full quantum dance with all its weirdness intact, although you could only truly prove that by sending the photons through the apparatus and detecting them one at a time. Such a procedure, unfortunately, remains beyond the average home experimenter.
