Materials Science: The Gateway to Science! : Materials Science: The Gateway to Science! Tom Stoebe Professor Emeritus Materials Science and Engineering University of Washington Presented by John M. Rusin Engineering Instructor, Retired Edmonds Community College


Outline : Outline Current status: K-12 Science Education Proven means for enhancing Science Education with examples The Bigger Picture What can WE do? Contacts/References


Current status: K-12 Science Education : Current status: K-12 Science Education Time Magazine: Are we flunking science? The World is Flat Science can be done any place where there are scientists Rising above the Gathering Storm National Academy report WA League of Women Voters Only 18% of WA HS freshman receive college degrees, few of these in science or engineering


Is this a crisis? : Is this a crisis? Probably NOT relative to the development of new ideas in science and engineering Possibly in terms of personnel to carry out the development of new ideas Probably YES in terms of basic science education and understanding


Why is there a problem? : Why is there a problem? Media focus has been away from science and engineering Engineering achievements not well known/taken for granted Computers Cell phones Flat panel TV sets Even scientists don’t give credit to engineering and technology (Peters ref.)


American Education System : American Education System Student-oriented inquiry learning, especially in early grades Focus on thinking and problem solving Students can choose subjects of greatest interest to them Science instruction mostly theory with some practical applications Too much theory, not enough application


Other countries : Other countries More focus on national need for scientists and engineers Direction to schools (national curriculum) Direction to parents and students BUT More rote learning Less innovation


Why is Science Education Important? : Why is Science Education Important? General public needs to understand more science Environmental issues Energy issues Technological issues Public needs to be able to make informed decisions!


Future scientists do great : Future scientists do great NSF enhanced K-12 science education programs Advanced math and science courses in high school But Not Many of them 2% of HS freshmen eventually get degrees in science or engineering


The average student does NOT like science! : The average student does NOT like science! Science is boring Chemistry is too much memorization Physics is too abstract Science is too hard, too much math…. And students with scientific aptitude go into business, medicine, history, economics, etc !


How can we approach this problem? : How can we approach this problem? Focus on real science that students understand Use examples that turn students on to science Get teachers excited about the subject!


Proven programs to introduce students to materials science: : Proven programs to introduce students to materials science: Materials Science and Technology, Battelle Pacific Northwest Labs Materials World Modules, Northwestern U. Materials Teach, U of Florida Materials Technology Institute, U of Washington Enhanced Materials Technology Project, Edmonds Community College ASM Teachers Camp program


Materials Science and Technology (MST) : Materials Science and Technology (MST) The science of “stuff” Hands-on activities, teams approach (75% lab-oriented) All classes of materials Focus on metals, ceramics, polymers, composites


Prevailing Concepts : Prevailing Concepts Build on student knowledge of everyday materials Apply basic concepts throughout all units Look at “stuff” from micro to macro Learn why and how “stuff” does what it does…by understanding the properties of the “stuff”


How is it Offered? : How is it Offered? Dedicated “stand-alone” class Incorporate into traditional science or technology class Modules


MST Modules : MST Modules Introduction: general properties of materials Metals Ceramics and glass Polymers Composites


Solids : Solids Importance of materials science and technology. Solids are typically separated into four categories. Simple chemistry including chemical bonding, the periodic table, and oxidation-reduction. Crystal structures, physical properties. How metals are claimed from their ores. Importance of maintaining a student journal and keeping good records is stressed.


Solids Activities : Solids Activities Material safety data sheets Identification of materials Formation of crystals Destructive testing Reactivity series of metals Oxidation/reduction of copper


Metals : Metals Properties and historical developments of metals. Mechanical properties of metals and heat-treating. Alloys and phase diagrams. Metals testing and manufacturing processes. Major project: making of sterling silver jewelry using the process of lost wax casting.


Metals Activities : Metals Activities Rolling a coin Drawing a wire Alloying copper and zinc Cost of a penny Making a light bulb Making lead-tin solder Annealing copper Powder metallurgy Lost wax casting


Sterling Silver Rings : Sterling Silver Rings


Ceramics & Glass Activities : Ceramics & Glass Activities Forming, firing, and glazing clay Thermal shock Glass bending and blowing Glass batching and melting Dragon dribble & dragon tears Coloring glass Stained glass project Making Raku Ceramic slip casting


Colored Glass : Colored Glass


Fused Glass : Fused Glass


Polymer Activities : Polymer Activities Cross-linking a polymer (slime) Polymer identification Making nylon 6-10 Latex rubber ball Memory in polymers Epoxy resin cast Polymer foam creations


Resin Cast Clothespin : Resin Cast Clothespin


Composite Activities : Composite Activities Stressed-skin composites Plaster of Paris matrix composite Compression and tension in a bending beam Laminated wood beams Using Portland cement to make & test concrete Hand lay-up of a glass fiber reinforced polymer

MST is FUN!!! : MST is FUN!!!


MST Training Resources : MST Training Resources PNNL MST Teachers Handbook: paper copies and CD 45 MST labs installed by Energy Concepts Inc. Over 1000 teachers trained in MST 500 schools are using Materials World Modules


ASM Materials Camp : ASM Materials Camp Teachers camp program Trains teachers in MST 18 camps in 2006 Sponsored by ASM Materials Education Foundation


States that have MST Classes : States that have MST Classes California Colorado Florida Illinois Iowa Kansas Massachusetts Michigan Mississippi Missouri Ohio Oregon Pennsylvania Tennessee Virginia Washington Wisconsin


Impact on Teachers : Impact on Teachers Concepts and labs apply to many science courses Raises interest and excitement among teachers Raises interest in science among their students to enhance learning “I think I learned more in a week of camp than I have in all of my science experience at school….I know that this is the most educating and fun experience I have ever had.” Jessica Gladysz, Albuquerque ASM Teachers Camp


Student Comments : Student Comments "I love working with materials. I learn so much easier by working with my hands." "It was a non stop action class. Almost everyday we are doing something new. I got to make a lot of cool stuff that I can keep forever." "My friends used this class as a stepping stone to get into the Manufacturing Boeing Internship in Auburn."


Student Survey (250 Students) : Student Survey (250 Students) When asked if they would recommend this class to other students: 76% said yes 19% said probably 5% said no “Materials Technology Education Program Impact on Secondary Teachers and Students,” T. Stoebe, G. Whittaker and K. Hinkley, Journal of Materials Education 24, 23-30 (2002).


Slide37 : HS Class Evaluation When asked to complete the following sentence, " I like materials science because,” students finished the sentence with three general themes: We learned about different materials and then were able to use them to make a project It involves hands-on work Lab activities were fun!


Slide38 : “Materials Technology Education Program Impact on Secondary Teachers and Students “ Thomas Stoebe, Guy Whittaker, Karen Hinkley, Journal of Materials Education, 24, 23-30 (2002)


Other Findings : Other Findings Students become more interested in further science study after taking this course Chemistry and physics courses became more popular as a result of the MST course. Significant enhancement in the understanding of science and in career opportunities in science and technology Provides a means for motivating teachers to engage students more in real science and to motivate students toward more understanding of science and engineering.


Other approaches : Other approaches Materials camp for high school students ASM Materials Education Foundation 25 camps in 2006 Focus on exciting kids in science Evaluation shows kids refocus on science, engineering, technology


The Bigger Picture : The Bigger Picture Middle school (ages 11 - 14) is where kids loose focus on science Courses not interesting Kids turned off to math Science teachers have only general science training (if any) SO---Why not a curriculum that uses MATERIALS as the base for ALL of K-12 science?


What would be needed for a materials-based school curriculum? : What would be needed for a materials-based school curriculum? Educators Curriculum designers Materials experts FUNDING Most important: A change in philosophy in science teaching!


What is currently available? : What is currently available? High school level curricula MST, MAST, MWM, etc Albuquerque materials chemistry example Innovative college-level curricula MRSEC programs
