During the Fall of 2013 SCME is hosting a series of workshops related to microtechnology. These workshops focus on classroom activities related to STEM and microtechnology concepts that can easily be incorporated into your existing curricula. All workshops are on a Saturday from 9 a.m. to 3:30 p.m. at the University of New Mexico's South Campus, 800 Bradbury SE, Albuquerque, New Mexico.
Each workshop includes the following:
- Detailed instruction in microtechnology topics
- Specific information on using classroom kits to teach microtechnology topics
- Complete coverage of the kit material and supporting learning modules
- Time to discover how the kits and learning modules meet the STEM and NGSS standards
- Strategies for incorporating the topics and activities into your curricula.
Following are brief descriptions of the workshops:
Comparison of Scale: Saturday, September 14, 2013
This workshop covers a variety of topics ranging from the history of weights and measures to the applications of weights and measures in microtechnology. Activities include methods for converting from one unit to another, and one measurement system to another. Participants apply this method to a variety of microtechnology applications (e.g., inkjet printers, gold metallization fabrication). Other activities include creating illustrations and logarithmic scales of objects that range from the macro-scale to the nano-scale. Participants also have the opportunity to view a variety of objects using a virtual scanning electron microscope.
The Science of Micro-films (Rainbow Wafer), Saturday, September 28, 2013
This workshop covers a variety of material related to the thin films used in microtechnology. Topics include oxidation of silicon dioxide, wet vs. dry oxidation, silicon dioxide etch, interpreting silicon dioxide thicknesses, and light interference of thin films. Activities include comparing and contracting wet and dry oxidation processes, visually estimating various silicon dioxide thicknesses on silicon wafers, calculating etch rates, creating graphs using collected data, and determining the various relationship between silicon dioxide thicknesses, time, and etch rates. This workshop introduces the Rainbow Kit that can be used in the classroom to support all of these activities.
MicroPressure Sensor (Pressure Sensor Model), Saturday, October 12, 2013
This workshop cover topics related to MEMS pressure sensors. Topics include simple series and parallel electronic circuits, the series-parallel Wheatstone bridge circuit, strain gauges, how a MEMS pressure sensor works, its applications, and how it is fabricated. Activities include measuring resistance, voltage and current, comparing the resistivity characteristic of various materials, building a macro-sized pressure sensor, and testing your pressure sensor for changes in applied pressures. This workshop uses SCME's Pressure Sensor model kit to provide hands-on learning of many of these activities.
DNA Microarray (GeneChip Model), Saturday, October 26, 2013
This workshop covers many topics related to the DNA microarray. Topics include DNA transcription, DNA hybridization, DNA microarray types, applications, fabrication and interpretation. The SCME GeneChip model kit is used to give participants the experience of simulating the fabrication process, an application process, and interpreting a microarray's results. Additional activities reinforce the understand of DNA transcription and hybridization.
MicroCantilevers, Saturday, November 9, 2013
This workshop covers a variety of topics related to MEMS Cantilevers. Topics include applications, fabrication, and operation. The workshop activities allow the participants to analyze both the static and dynamic modes of cantilever operations. Participants simulate a cantilever's operation under various "loads" (different masses). Cantilevers with different lengths, widths, thicknesses and of different materials are used to illustrate how these cantilever characteristics affect its operation. The SCME Dynamic Cantilever Kit is used to support these activities.
Crystallography, Saturday, November 23, 2013
This workshop covers topics related to polycrystalline and monocrystalline materials and the importance of crystal structures for the fabrication of micro-sized structures. Topics include the type of crystals, crystal planes and the Miller Index, and crystal planes and micro-fabrication. In the workshop activities participates become proficient in denoting different crystal planes and vectors using Miller Index notation, construct a paper-based crystal, and determine the crystal orientation of different silicon wafers. The SCME Crystallography kit is used to support these activities.
