Upcoming Materials In Stem (M-STEM) Workshop At University Of Alabama at Birmingham

Rockets and toothpicks do not seem to be related, but at this year’s upcoming M-STEM Workshop, hosted at the University of Alabama at Birmingham, STEM educators will find out how each one of these topics, plus many others, can help educators share how materials science can weave into every aspect of learning.

Over three decades, Materials in STEM (M-STEM), has served as a resource and aid to educators looking to add new ideas, hands-on projects and experiments, demonstrations and keynotes from professionals and other educators. During this two day, intensive workshop, on November 5 and 6, 2018, participants will gather to interact and connect with a wide range of experts. Three of the most popular past sessions will return for the 2018 event:

  • The Toothpick Factory
  • Teachers with Torches
  • Engineering Rockets

Each session is packed with ideas educators can take directly back to their classrooms and put into action to help students fall in love with STEM topics.

  • Motivating the Unmotivated Learner with STEM
  • Designing Features for Datums (related to 3D printing parts and projects)
  • Damping and Insulative Properties of Natural Fiber Composites
  • Practical Polymers
  • Nano Materials, Light and Water

The program is ideal for secondary and post-secondary faculty. In addition to the keynotes and sessions, there will be a Student Posters exhibit highlighting UAB student work in materials.

M-STEM is funded by the National Science Foundation (NSF) under a larger grant project known as the The National Resource Center for Materials Science Technology Education (MatEdU) based at Edmonds Community College in Washington State.

  • Vulcan Park and Museum with the world’s largest cast iron statue

 

Advanced Technological Education (ATE) Celebrates 25 Years

The 25th Anniversary of the National Science Foundation’s (NSF) Advanced Technological Education (ATE) program is a reason to celebrate in STEM (Science, Technology, Engineering, and Mathematics) education circles.

For 25 years, the ATE program has invested in and grown technician education opportunities around the nation to prepare a “STEM-capable workforce.” That includes many different types of classes, modules, and certificate programs, in addition to traditional two-year degree programs that are already a strong part of the community college system.

Here are just a few of the statistics:

  • $1.1 Billion is the total NSF ATE Investment to date
  • 715 organizations have received ATE funding
  • 61 ATE Centers and 1,294 Projects have been funded by ATE
  • In FY2017, $66 Million Went To 300-plus Active Grants

All of these efforts focus on technician education, across the USA, to help students graduate, but also to help high tech employers in the workforce. Many of the programs highlighted in the annual report called “Impacts” are part of the TEAMM network, which is the sponsor of AM News. Throughout this coming 2018-2019 academic year, we are going to highlight the network member programs as found in Impacts and through direct interviews, when possible.

ATE Impacts explores and reports on seven major categories:

  1. Advanced Manufacturing Technologies
  2. Agricultural and Environmental Technologies
  3. Bio and Chemical Technologies
  4. Engineering Technologies
  5. General Advanced Technological Education
  6. Information and Security Technologies
  7. Micro and Nanotechnologies

Today we will look at one featured Project and one ATE Center:

Featured Project: AM-WATCH (Additive Manufacturing – Workforce Advancement Training Coalition and Hub)

According to Impacts:  “AM-WATCH provides opportunities for secondary school and two-year college students and educators to learn additive manufacturing technologies. More than 700 students were impacted positively by the project from fall 2017 to spring 2018.” It plans to add more locations to its existing 25 learning sites in Tennessee and Washington.

In a recent Train-the-Trainer Studio, educators were taught how to build 3-D printers to help them prepare technicians for additive manufacturing careers.  Results found that educators:

  • 77% increased their ability to design a system, component, or process
  • 80% increased their technical and nontechnical communication skills
  • Educators report AM-WATCH’s Train-the-Trainer Studios improved their performance on specific ABET accreditation skill sets

ATE Center: MatEdU – National Resource Center for Materials Technology Education

MatEdU is well-known as a materials technology education repository for educators and students. It appears in the number one spot for search engine results for a wide variety of materials science terms and directs students and educators to useful resources.

Students can learn about a variety of career pathways in materials science. Educators can find content that helps them plan a variety of lessons, entire courses as well as core competencies documents outlining required depth of proficiency for a range of related subjects, such as, manufacturing technology, corrosion technician, nanotechnologist, and more. Instructional resources include course designs, materials videos, and recommended book lists, to name just a few items from the Instructional Resources page.

Each year, MatEdU organizes a Materials in STEM conference (two days) known as M-STEM that attracts educators and students around the country. This year is hosted by the University of Alabama – Birmingham on November 5 and 6.

The Facility Is Creating A Sustainable Makerspace Model To Aid Student Job Potential

According to the Credit reporting site WalletHub, Washington State’s economy ranked No. 1 in the nation, driven by strong gross domestic product growth, exports, and the percentage of high-tech jobs. Those high tech jobs include careers in STEM (Science, Technology, Engineering, and Math).  Of course, that would mean that advanced science fields, such as materials science and additive manufacturing rank high, as well.

Student education and workforce training programs contribute to that job growth and overall career opportunities. So, it comes as no surprise that Edmonds Community College enthusiastically supported the idea of creating a makerspace for students and the community. The makerspace is called The Facility and is housed in Monroe Hall, which is already a well-equipped materials science lab.

The Facility is different than many college makerspaces, however, because it is a hybrid model that allows student use and also invites the community, residents who are not students, to come and use the space at low cost. As you will hear in this short video, David Voetmann, Makerspace Program Manager of The Facility, explains how the process works for joining and participating in the space.

What is a Makerspace?

Briefly, a makerspace is like a woodshop or metal shop or automotive class that many area residents would remember. A place, as Voetmann says, to share tools and innovation. Except instead of only power saws or welders or impact wrenches, you would have 3D printers, laser cutters, or 5-axis CNC machines – computer-controlled milling machines that cut on multiple angles. In addition, Monroe Hall is unique in that it is home to equipment that can make something out of carbon fiber (materials science) via vacuum bagging and an autoclave, not your usual makerspace gear.

You can check out other TEAMM videos or look at the Materials Education channel on YouTube.

Resources for Starting Your Own Makerspace

Since two of the most popular machines in a makerspace are 3D printers and laser cutters (or laser engravers), it is logical that companies that provide those tools would have good resources.

3D printer manufacturer, Ultimaker, has a number of posts, books, and resources for school teachers, administrators, librarians (public and school), who might be interested to build a makerspace. One is called the Makerspace Bookshelf and the other helpful post is Fablab, makerspace, or hackerspace? –that highlights how to decide which one is right for your situation.

LulzBot, one of the dominant 3D printer brands in education, has a case study on the Loveland CreatorSpace: Come for the Tools, Stay for the People.

FormLabs, a resin-based 3D printer company, published Incentives and Ingredients for Building a Makerspacethat is instructive.

If you have been contemplating a laser cutter, and a variety of other equipment, Epilog Laser, based in Colorado, offers a number of posts and a downloadable guide for lasers in education to help you determine what you need as well as steps to take to get your space up and running. This post (though it presents a slight bias given what they sell) Why Will a Laser be the Most Popular Tool in My Makerspace? presents four reasons why a laser will be a hit in your makerspace, hackerspace, or fab lab.

Laura Fleming, an educator and media specialist, has written two excellent, best-selling books (also mentioned on the Ultimaker site). You can find both of them on her website: Worlds of Making. Both of them are about creating a makerspace in your school. They are also available on Amazon. She offers a steady stream of ideas and maker tips on her Twitter account – @LFlemingEDU.

The study mentioned earlier in the post: WalletHub study: 2018’s Best & Worst State Economies. This article on the Edmonds Community College website gives additional details of how the school intends to use the makerspace: The Facility and the Rapid Proto Lab at Edmonds Community College.

Berkeley Lab Develops 3D Print Structures Composed Entirely Of Liquids

Just as people have begun to understand and use 3D printing, here comes a new technology: Liquid 3D printing from one of the top government labs. With 13 Nobel prizes, 70 scientists who are members of the National Academy of Sciences (one of the highest honors for a scientist in the U.S.), numerous National Medals of Science under their belt, the Lawrence Berkeley National Laboratory (Berkeley Lab) knows a bit about how to adapt and tweak materials properties to get what they want.

Recently, the Berkeley Lab has developed a way to print 3D structures composed entirely of liquids (Full details linked at end of post). There are existing 3D printers that can do this, so, naturally, the Berkeley Lab team modified an existing 3D printer to do what they wanted: inject threads of water into silicone oil. This allowed them to sculpt tubes made of one liquid within another liquid. This YouTube video from the team at Lawrence Berkeley National Laboratory elegantly demonstrates and explains how they got it to work.

The Berkeley Lab team believes their all-liquid material could be used to construct liquid electronics that power flexible, stretchable devices. If you have seen the new Samsung flexible, foldable phone screen, you have a rough idea of the concept in action.

According to the official post, “the scientists also foresee chemically tuning the tubes and flowing molecules through them, leading to new ways to separate molecules or precisely deliver nanoscale building blocks to under-construction compounds. The researchers have printed threads of water between 10 microns and 1 millimeter in diameter, and in a variety of spiraling and branching shapes up to several meters in length. What’s more, the material can conform to its surroundings and repeatedly change shape.”

Read more details about how the Lab created a nanoparticle “supersoap” – a surfactant that locks the water in place as they create tubes.

Materials Scientists Working On Dental Enamel That Could Regenerate

You never know where an opportunity will present itself for a materials science technician. Your local dentist or dental lab may need help in the near future if this research from Queen Mary University of London, United Kingdom develops.

Earlier this month, researchers announced they were working on a new way to grow “mineralized” materials that mimic hard tissues – dental enamel or bone.

The study, originally published in Nature Communications, show how new materials can be recreated to look and work like natural dental enamel. The researchers believe that it could help prevent tooth decay and sensitivity and also provide a way to treat those conditions.

According to the paper:

“Enamel, located on the outer part of our teeth, is the hardest tissue in the body and enables our teeth to function for a large part of our lifetime despite biting forces, exposure to acidic foods and drinks and extreme temperatures. This remarkable performance results from its highly organised structure.”

The paper cites “lead author Professor Alvaro Mata, also from Queen Mary’s School of Engineering and Materials Science, who said: ‘A major goal in materials science is to learn from nature to develop useful materials based on the precise control of molecular building-blocks. The key discovery has been the possibility to exploit disordered proteins to control and guide the process of mineralisation at multiple scales. Through this, we have developed a technique to easily grow synthetic materials that emulate such hierarchically organised architecture over large areas and with the capacity to tune their properties.'”

Mimic other hard tissues

As the researchers understand and control how the process of mineralization works, they believe they will be able to mimic other hard tissues. That potential makes it interesting and valuable to other specialties within the medical and dental communities, particularly in regenerative medicine.

An understanding of how materials work is going to be increasingly valuable in our materials research-based world. Whether it is dental enamel, human bones, or carbon fiber, materials science technicians have a bright future.
