Portable Light Project Intro Slides (for teachers)

  1. 1. The CSSI Curriculum :<br />Constructing Science for Social Impact<br />
  2. 2. Curriculum Overview<br />Interact<br />Reflect<br />
  3. 3. The Portable Light Project is a non-profit research, design and engineering initiative established by KVA MATx that creates new ways to deliver de-centralized renewable power and light to the developing world. Each Portable Light unit is a simple, versatile textile with flexible photovoltaics and solid state lighting that can be adapted to local cultures and customized by people using traditional weaving and sewing technologies in an open source model. This creates the opportunity for greater levels of cultural acceptance and stewardship of this technology, particularly for women who are often among the most vulnerable in developing countries.<br />Engage<br />
  4. 4. The Reading Mat Prototype<br />High brightness solid state lighting<br />Flexible photovoltaic technology<br />12V of DC electrical power<br />160 lumens of light<br />Five hours charge time<br />Engage<br />
  5. 5. The Challenge<br />Using the Gogoboard & any sensors, design an experiment to detect how much solar power can be harvested from such garments<br />Design your own Portable Light Project prototype<br />Using Netlogo, create a model to show the social impact of the Portable Light Project<br />Engage<br />
  6. 6. GogoBoard & Sensors<br />Ignite<br />
  7. 7. 3D Printer<br />Ignite<br />
  8. 8. Laser Cutter<br />Ignite<br />
  9. 9. Construct<br />Students construct models and prototypes<br />
  10. 10. Construct<br />Students convert sensor information into concepts of electricity, current, power <br />
  11. 11. Essential questions and Links to California Science Standards<br />Questions to Ask<br />Link to Standards<br />What is DC?<br />What is voltage & current?<br />How to construct a simple circuit? – what are resistors and capacitors?<br />What is solar power? What is power?<br />How much solar energy does the earth obtain?<br />What happens to the solar radiation that comes to earth?<br />Electric Phenomena<br />Ohm’s Law<br />Voltage/current predictions in simple circuits<br />Resistors & transistors<br />Power calculations<br />Energy in the Earth System<br />Solar radiation as the earth’s primary energy source<br />Construct<br />
  12. 12. Unite<br />Possible Prototypes & Products<br />
  13. 13. Shirt with multiple light sensors, attached to Gogo Board<br />Unite<br /><ul><li>Student wears the shirt and walks around all day
  14. 14. GogoBoard collects data on light intensity through the day
  15. 15. Can ascertain position of the solar panel for maximum light absorption</li></li></ul><li>Shirt with solar cell attached to battery charger<br />Unite<br /><ul><li>Student wears the shirt and walks around all day
  16. 16. Can ascertain how long it takes to charge up some batteries</li></li></ul><li>House with variable roof angle; solar panel and light sensor attached to roof<br />Unite<br /><ul><li>Can ascertain the amount of light obtained at various roof angles; compare with data from the shirt
  17. 17. Solar panel vs light sensor : information can be used for calibration of sensor.</li></li></ul><li>Social Interactions & Personal Reflectionswww.cssi.weebly.com<br />Interact<br />Reflect<br />
