Squishy Circuits | The Tinkering Studio | Exploratorium Using a concentric design and resistive dough, cool parallel circuits are possible All the ingredients that you need to make your own conductive and resistive Play-Doh Wrap the dough in plastic film and store in ziploc bags to keep it moist longer Integrating LED lights and power source into a sculptural design Exploring complex circuitry becomes natural We use food coloring for conductive dough, and leave the resistive kind white, so you always know which one you're using We like to use 9V batteries. Sometimes conductive Play-Doh is just Play-Doh Troubleshooting with a partner Using the dough to make a direct connection between the battery and an LED light
TEDtoChina Shanghai: The Upcoming Sixth Sense Talk Pranav Mistry is a ‘human interaction interface innovator’ from MIT. Back in 2009 he gave his first talk at TED about his Sixth Sense technology which is a holographic touch sensitive projector that’s workable on any surface. It’s an augmented reality technology that allows you to compute anywhere anytime with gesture controls for everything. For the first time Pranav will be talking about his Sixth Sense projector in Shanghai at TEDtoChina this Sunday 18th September. 100 participants will be invited to the event, you can apply for your invitation here. About Pranav Mistry: Currently Research Assistant and PhD candidate at MIT Media Lab.Previously UX Researcher at MicrosoftMasters in Media Arts and Sciences from MITMaster of Design from IIT Bombay For those you who haven’t seen this Sixth Sense technology, watch this video of Pranav’s TEDtoIndia talk in November 2009. TEDtoChina is a community of volunteers who are committed to the idea of TED, and are active in spreading the TED meme.
How a Smoke Detector Works Part of the show Nuclear Power What you Need A smoke detector Geiger counter - we needed to check that the radiation levels aren't going to do us any damage! Some tools Candle and something to burn What to do You should NOT try this experiment at home because radiation is dangerous. 1 - Open up the smoke detector and take a look inside. 2 - Carefully remove the casing covering the radioactive metal. What may happen When the Geiger counter is put close to the radioactive source, the counter went crazy! Why does it happen? If you take a look inside a normal smoke alarm, you'll see a loud speaker, a battery, electronics, and a silver coloured cover. But what role does this radiation play inside a smoke detector? This is where the radioactive americium comes in. In the event of a fire, tiny smoke particles move into the gap and mop up the free electrons, which stops the current flowing and breaks the circuit.

Science through LEGO Engineering The following four curricula are designed to introduce students (in Grades 3 to 5) to various science concepts through design-based LEGO projects. The first several lessons of each unit engage students in scientific explorations sometimes using the LEGO tool-set as a resource. The students are then charged with an open-ended design challenge where they use the science they learned alongside the engineering design process to design and build LEGO creations that meet criteria that the students can observe and test. Intro Unit This series of introductory lessons should be completed before beginning a Science Through LEGO Engineering curriculum unit. Download Introduction Unit (PDF, 2.3MB) Design a Musical Instrument: The Science of Sound This curriculum engages students in explorations about the science of sound, which culminates with students designing and building a musical instrument that plays at least three different pitches.

Sparks | Search Institute Educators and youth leaders know how motivating it can be for young people to discover their "sparks"--those activities and interests that truly engage kids to be their best. Discovering those sparks can help students express their personalities and make unique contributions to the world. Search Institute research shows that kids who thrive have two important supports: knowledge of what their sparks are and adults who support the development of those sparks. Several research studies show that creative arts, athletics, and learning are the top interests that kids identify as their personal sparks. Read the research and help us make sure kids know their sparks, grow them, and share them.

TEDxUofM’s Robert Bartlett talks about the importance of translation research — research that can have an immediate and life saving impact. Genevieve Bell worries that with the increasing use of cellphones and laptops humans will never be bored again, and makes the case for why boredom and unstructured downtime is important for individuals and relationships.
Marble Machines Multiple paths are possible and encouraged! Catching marbles at precise points in the path becomes a great challenge Getting a marble out of a stuck position might require a little ingenuity… Discussing possible solutions and approach is part of the collaborative nature of tinkering Using a spring as a track for the marble Visitors building Marble Machines in our dedicated space at the Exploratorium
