Wet vs. Dry Oxidation Processes
No full textIn this YouTube video, created by Southwest Center for Microsystems Education (SCME), viewers can watch an animation on the the difference between wet and dry thermal oxidation processes. This animation "shows a side by side comparison of a wet oxidation process vs. a dry oxidation process. Both processes use an oxygen source to grow silicon dioxide (SiO2) on a silicon wafer heated furnace. Wet thermal oxidation uses water vapor. Dry thermal oxidation uses oxygen gas." Viewers can learn more on this topic in the Deposition Overview for MEMS Learning Module which can be found on the SCME website along with supplementary materials.Â
Weights and Measures Part III
No full textThis YouTube video, created by Southwest Center for Microsystems Education (SCME), is the third in a series created to educate viewers about weights and measures in the context of nanofabrication. This segment, which is 21:10 minutes long, covers prefixes used in units of measurement- from the history of units of measurement to the SI system. Viewers can learn more about this topic on the SCME website and other supplementary materials on measurement.Â
Micropumps Overview
No full textThis page from the Support Center for Microsystems Education covers an overview of Micropumps. Viewers will find both an Instructor and a Student Guide which contain information on micropumps, macropumps, the differences between mechanical and non-mechanical pumps, and the application of pumps in general in microtechnology.Â
Caribou Conservation Conundrum
No full textThe National Center for Case Study Teaching in Science has worked with dozens of scientists over the years to bring forth a range of wonderful teaching resources. The case study method is well-known in the field, and the offerings on the main website cover biology, ecology, zoology, and other disciplines. This particular case study was authored by Kyla Flanagan of the University of Calgary and Jalene M. LaMontagne of DePaul University, and it looks at how scientists and others might work to preserve the habitat of the caribou in northern Alberta. On the site, visitors can read an abstract of the case study, peruse its objectives, and then dive right in. Users will find a set of Teaching Notes, Supplemental Materials, and comments from those who have utilized the materials. It's a rather useful teaching tool, especially for those in the biological sciences
Basic Electronics Tutorials
No full textThis site gives a number of tutorials and information to help students and instructors develop a knowledge and understanding of the basics of Electronics. Topics include amplifiers, inductors, capacitors, electromagnetism, transformers, transistors and more
NASA's Earth Observing System
No full textNASA's Earth Observing System (EOS) is "a coordinated series of polar-orbiting and low inclination satellites for long-term global observations of the land surface, biosphere, solid Earth, atmosphere, and oceans." On their website, visitors can learn about the EOS's various projects and initiatives via their in-house newsletter, âThe Earth Observer,â and by looking at their vast collection of images captured by satellites. Users can select the Images by Mission drop-down menu to peruse images from fifteen different missions, including Aquarius, ICESat, and SeaWinds. The site also contains a Communications area, which offers up key publications, educational posters, calendars, booklets, and facet sheets
National Institute of Environmental Health Sciences: Lesson Resources for Teachers
No full textScience teachers around the country and the world have a good friend in the National Institute of Environmental Health Sciences. They have brought together dozens of helpful teaching aids in this fine corner of their website. There are booklets, fact sheets, websites, and flyers all arranged into neat and tidy sections. The Booklets area includes "You and Your Genes-Making it in a Tough Environment" and "Guide to Keeping Laboratory Notebooks." The Fact Sheets section includes overviews of endocrine disruptors, allergens, and environmental factors and breast cancer risk. Additionally, the Interviews with Scientists/Researchers section is quite inspiring and features conversations with a lung doctor, an environmental analyst, and a microbiologist
The Effects of Gold and Silver Nanoparticles on Brine Shrimp: A Toxicology Study
No full textIn this lab students will study nanoparticles, specifically dilutions of gold and silver. Students will study brine shrimp and explore "...the effects of exposing living organisms to different nanoparticles at various concentrations." There is a twenty-one page teacher's preparatory guide, containing: lists of equipment and materials needed, activity procedure, and student guide with answer key. The student guide is also available as a separate PDF document. Â
Additive Manufacturing: Materials and Processes
No full textThis classroom module will give students "an overview of the materials used in Additive Manufacturing printers, including the properties, process, Strength, production time, uses, post processing requirements and relative cost for use." At the end of the lesson, students will have a general understanding of the materials and processes utilized in additive manufacturing, as well as which materials and processes are appropriate for 3D printing. The lesson is intended to be delivered in lecture format and should take approximately 1 hour. Evaluation questions are included, and the information can be adapted for students from late middle school through early community college education
Scitable
No full textScitable is a completely free science library and personal learning tool created by the Nature Publishing Group. The work is currently focused on genetics and cell biology and covers topics such as evolution, gene expression and "the rich complexity of cellular processes shared by living organisms." At the Inside Scitable area, visitors can browse and search hundreds of science articles, use the discussion board, build an online classroom, and also contribute and share content. First-time visitors should head on over to the Spotlight area, where they can read quality pieces on World Teacher's Day, nanotechnology, and other topics. Also, visitors shouldn't miss the Labcoat Life area, which contains musings on topics like "Tackling Mental Illness in Africa" and "Is Global Warming Chiefly Manmade?"
