Dark matter is the thread connecting galaxy clusters Simulations of the Universe on the largest scales show an unexpected resemblance to nerve cells in the human brain, with galaxy clusters playing the role of the cell body and thinner filaments of matter linking them like axons. Galaxy surveys (such as the Sloan Digital Sky Survey, or SDSS) show that galaxies do cluster like our simulations predict. But the filaments that should connect them have been harder to find. Most of the mass in the Universe is dark matter—material that neither emits nor absorbs light—and filaments are predicted to be mostly dark matter: no galaxies, little hot gas. Einstein's general theory of relativity, however, tells us mass affects the path of light, and a group of astronomers have identified a dark matter filament by measuring this effect.
Higher Education Academy Engineering Subject Centre The Engineering Subject Centre has produced a series of peer reviewed guides looking at various aspects of teaching and learning aimed at all those involved in engineering education. The guides have been written by Engineering Subject Centre staff, Associates and other experts in the field. Available in print, pdf and online formats, it is hoped that the online version will encourage participation and feedback from the community and that the resources will then develop interactively over time, ensuring that content is current and relevant.
10 Incredible Chemical Reaction GIFs Explained We encounter thousands of chemical reactions every day: plants use them in photosynthesis, metals rust over time, and combustion reactions provide us with heat and light, among thousands of other daily uses. Chemical reactions occur when reactants transform into new substances, called products, through creating and breaking bonds between atoms. Sometimes the process creates some pretty wild effects. Engineer Your World: Engineering Design and Problem Solving for High Schools BackgroundEngineering design is not simply a useful tool for teaching science and mathematics content, but it is also a unique discipline in which science and mathematics are employed as tools for solving design challenges. With generous support from the National Science Foundation (NSF) and in partnership with national organizations including NASA, the UTeachEngineering program at the University of Texas, Austin, has undertaken to demonstrate how rigorous engineering content can be deployed in secondary classrooms. Together, we have developed, piloted, refined, and deployed a year-long high school engineering course built on a foundation of solid research in the learning sciences, couched in the context of a rigorous engineering design process, and scaffolded to build engineering skills and habits of mind. We have also tested a variety of teacher preparation and support models that continue to evolve in response to the needs of our diverse teacher population.

History Clear evidence of the distillation of alcohol comes from the School of Salerno in the 12th century. Fractional distillation was developed by Tadeo Alderotti in the 13th century. A retort Distillation Integrated Design Engineering Activity Series IDEAS Engineering in the Middle School Classroom! IDEAS is the result of a project funded by The Engineering Foundation and organized by two of the worlds major engineering societies, the American Society of Mechanical Engineers (ASME) and the American Society of Civil Engineers (ASCE). Our goal when soliciting project activities was to identify low-cost, "hands-on" engineering projects for use in middle schools math, science and technology classes.
The Molecular View of Equilibrium Text below taken from Kinetic Theory of Gases: Molecular Speeds Other sections state that increasing the temperature increases the speeds at which molecules move. We are now in a position to find just how large that increase is for a gaseous substance. Combining the ideal gas law with Eq. (1) from The Total Molecular Kinetic Energy, we obtain or Engineering and Science Activities This page serves as a directory of ready-to-use activities and curricula for informal science educators to engage students with engineering and science.

Build an Atom - Phet Topics Atoms Atomic Structure Isotope Symbols Atomic Nuclei Description Build an atom out of protons, neutrons, and electrons, and see how the element, charge, and mass change. Rethinking the Way College Students Are Taught It's a typical scene: a few minutes before 11:00 on a Tuesday morning and about 200 sleepy-looking college students are taking their seats in a large lecture hall - chatting, laughing, calling out to each other across the aisles. Class begins with a big "shhhh" from the instructor. This is an introductory chemistry class at a state university. Chemistry Labs - OnlineLabs.in - Virtual laboratory simulations for science education Below is a list of freely available online chemistry lab resources, including general chemistry and organic chemistry simulations. Virtual Lab Simulator – From The ChemCollective. It started as the IrYdium Project’s Virtual Lab. There is extensive documentation for the lab, including an instruction video. The Java lab applet is translated into Spanish, Portuguese and CatalanVirtlab: A Virtual Laboratory – Registration required, but you can join Virtlab for freeVirtual Chemistry Experiments – Chemistry and Physics applets and phylsets from Davidson University.
American Modeling Teachers Association The Modeling Method has been developed to correct many weaknesses of the traditional lecture-demonstration method, including the fragmentation of knowledge, student passivity, and the persistence of naive beliefs about the physical world.
