TRS Drawbot Once you get the hang of using TRS Drawbot, experiment with the different effects you can create by changing pens, substituting in other marking tools like pencils or crayons, working on different types of paper, adjusting the hardware, and tweaking the WAVE synthesizer parameters. Pens that "bleed" into the paper can create interesting effects at slower drawing speeds. For instance, dramatically increasing the endpoint "dwell" time in the WAVE Synthesizer code to a second or longer causes an interesting "connect-the-dots" effect with a felt-tip marker. Likewise, the amount of sliding friction under the forearm will affect line quality. If the forearm does not make contact with the page surface at all, and is resting only lightly on the pen tip, the pen's movements will be faster but less stable; sometimes a "shaking" phenomenon occurs that creates an interesting sketch-like effect.

Science & Cooking: From Haute Cuisine to Soft Matter Science *Note - This is an Archived course* This is a past/archived course. At this time, you can only explore this course in a self-paced fashion. Certain features of this course may not be active, but many people enjoy watching the videos and working with the materials. Make sure to check for reruns of this course. During each week of the course, you will watch as chefs reveal the secrets behind some of their most famous culinary creations — often right in their own restaurants. Topics will include: soft matter materials, such as emulsions, illustrated by aioli; elasticity, exemplified by the done-ness of a steak; and diffusion, revealed by the phenomenon of spherification, the culinary technique pioneered by Ferran Adrià. To help you make the link between cooking and science, an “equation of the week” will capture the core scientific concept being explored. Before your course starts, try the new edX Demo where you can explore the fun, interactive learning environment and virtual labs.

Paper Generators: Harvesting Energy from Touching, Rubbing and Sliding Disney Research, Pittsburgh We present a new energy harvesting technology that generates electrical energy from a user’s interactions with paper-like materials. The energy harvesters are flexible, light, and inexpensive, and they utilize a user’s gestures such as tapping, touching, rubbing and sliding to generate energy. The harvested energy is then used to actuate LEDs, e-paper displays and other devices to create interactive applications for books and other printed media. Research Paper Paper Generators: Harvesting Energy from Touching, Rubbing and Sliding Karagozler, M. Technical Details Paper Generators are based on electrets: materials that hold quasi-permanent electric charge. The operation of the Paper Generators relies on the movement of the two conductive sheets relative to each other and the electret, PTFE. The same principle of operation applies to the horizontal movement of the top electrode (sliding). Team and Credits Contact Email: emre.karagozler [at] disneyresearch [dot] com
Science Museum of Minnesota - Shimmr Glittr The Learning Technologies Center is an applied educational research and development center of the Science Museum of Minnesota. Our mission is to support informal science learning through creative and meaningful applications of classic and emerging technologies. Take a look at the LTC history Through our work LTC has developed an engineering-design continuum to support our mission: Play » Tinker » Make » Engineer » This continuum is supported by a pedagogical approach to develop resources and environments that support the facilitation of inquiry moving into design experiences for learners Inquiry » Design » Engineering Design Washington County Library is hosting its first Maker Fest on Saturday, October 24, from 10 a.m. to 3 p.m. at Woodbury Central Park, 8595 Central Park Place.

Pescepollo - Lavoretti manuali con materiale riciclato, il robot Che bello questo robot, vero? Per realizzarlo prendete due scatole di dimensioni diverse, una per la testa ed una per il corpo. Per avere una scatola pulita e priva di scritte potete staccare le parti della scatola incollate tra loro e rimontarla al contrario (con l'interno pulito ora diventato esterno). Ho costruito il collo come nel disegno prendendo un rotolino di carta igienica a cui ho tagliato delle parti lasciando due linguette che inserendo nella scatola del corpo ho piegato e incollato. Ritaglia tre forme per gli ingranaggi e fissale alla scatola con un fermacampione così potranno girare. PESCEPOLLO lavoretti manuali per bambini
Sticky Actuators Making robots that move is not an easy task. That’s why we leave that to trained engineers and other really smart people. But what if animating robots became as easy as printing an actuator, sticking it to an inanimate object, and using air to compress and decompress the actuator to spur movement? A team comprised of Ryuma Niiyama from the University of Tokyo and several colleagues from MIT are behind the creation, which genuinely simplifies the way we can animate objects in real-life. The Sticky Actuators are plastic pouches with an adhesive backing that you stick to the joints of the objects you want to set in motion. For their experiments, the team built a custom fabrication machine that simply moves a soldering iron over two sheets of thermoplastic in order to bond them, leaving pouches in the middle where air can enter.
Exploratorium Institute for Inquiry: About the Institute Good science education requires both learning scientific concepts and developing scientific thinking skills. Inquiry is an approach to learning that involves a process of exploring the natural or material world, and that leads to asking questions, making discoveries, and testing those discoveries in the search for new understanding. Inquiry, as it relates to science education, should mirror as closely as possible the enterprise of doing real science. The inquiry process is driven by one’s own curiosity, wonder, interest, or passion to understand an observation or to solve a problem. The process begins when the learner notices something that intrigues, surprises, or stimulates a question—something that is new, or something that may not make sense in relationship to the learner's previous experience or current understanding. The next step is to take action—through continued observing, raising questions, making predictions, testing hypotheses, and creating conceptual models.
