MacVicar was an outstanding educator and scientist who founded MIT's famous Undergraduate Research Opportunities Program (UROP) and went on to serve as MIT's first Dean for Undergraduate Education until her untimely death in 1991 at the age of 47. She was nationally recognized for her leadership in shaping policies both for undergraduate education and for science education in public schools. The MacVicar Faculty Fellowship program was established in her memory and has become one of MIT’s highest teaching honors. This video was created on the 10-year anniversary of her death to remember Professor MacVicar and her many contributions at MIT. 318 tag:techtv.mit.edu,:Array/220966280 2008-06-20 16:53:07 -0400 MIT Department of Physics Technical Services Group <p>A light bulb is placed in series with two copper plates immersed in de-ionized water. Touching the plates closes the circuit, lighting the bulb.</p><p>When kosher salt is dropped into the de-ionized water, the salt dissolves, causing ions to be dispersed throughout the liquid. The free ions allow current to flow through the water, which completes the circuit and lights the bulb.</p><p>Most water we encounter in everyday life is not de-ionized and contains impurities with dissolved ions. This is why we know water as a good conductor, and why we shouldn't use electronic devices around a bathtub, for example.</p> 54 tag:techtv.mit.edu,:Array/220942180 2007-10-21 13:51:18 -0400 Scratch Video by Jay Silver and Karen Brennan 36 tag:techtv.mit.edu,:Array/220919640 2007-10-21 09:58:14 -0400 Scratch Children programming user-generated content.

From coral reef regeneration to energy resources to medical technologies to new science programs for schools, MIT students gain confidence, competence, knowledge, and experience that enables them to recognize their place as leaders of positive change. 215 tag:techtv.mit.edu,:Array/220874040 2009-02-06 13:03:11 -0500 nextlab NextLab is a hands-on design course in which students research, develop and deploy mobile technologies for the next billion mobile users in developing countries. Guided by real-world needs as observed by local partners, students work in multidisciplinary teams on term-long projects, closely collaborating with NGOs and communities at the local level, field practitioners, and experts in relevant fields. 314 tag:techtv.mit.edu,:Array/220844980 2009-02-20 09:52:36 -0500 MIT Department of Physics Technical Services Group First, an adjustable parallel-plate capacitor is held at a constant voltage. As the separation between the plates is widened, the electrometer shows charge (or current) flowing off of the plates, while the electroscope shows no change in voltage. Notice (by the deflection of the needle) that more charge flows off of the plates when they are closer together, and less when further apart. When the plates are brought back together, we see charge flowing back onto of the plates. <br><br> Next, we deposit a fixed amount of charge onto the left plate. Now, when the separation is widened, the electroscope shows a rising voltage, even as the amount of charge stays constant. When a block of plexiglass (a dielectric) is inserted between the plates, the voltage drops. However, when the plexi is removed, the voltage rises back up again, showing that the charge is still there. <br><br> This is one of the main reasons capacitors are built with dielectrics between their plates; more charge can be stored at a lower voltage. 126 tag:techtv.mit.edu,:Array/220825000 2009-04-16 11:06:25 -0400 MIT Department of Physics Technical Services Group A laser is directed at an adjustable single slit and then a pinhole and the resulting diffraction patterns can be seen on a screen. <br><br> A laser directed at two slits spaced closely next to each other creates an interference pattern within the diffraction pattern. Shining lasers of different wavelength light shows how the wavelength affects the interference and diffraction patterns. 146 tag:techtv.mit.edu,:Array/220804580 2009-04-23 11:35:51 -0400 New Media Literacies Henry introduces NML's ideas on mapping at our Mapping Think Tank in January 2009 182
