Portable Light Project Intro Slides (for teachers) Portable Light Project Intro Slides (for teachers) Presentation Transcript

  • The CSSI Curriculum :
    Constructing Science for Social Impact
  • Curriculum Overview
    Interact
    Reflect
  • 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.
    Engage
  • The Reading Mat Prototype
    High brightness solid state lighting
    Flexible photovoltaic technology
    12V of DC electrical power
    160 lumens of light
    Five hours charge time
    Engage
  • The Challenge
    Using the Gogoboard & any sensors, design an experiment to detect how much solar power can be harvested from such garments
    Design your own Portable Light Project prototype
    Using Netlogo, create a model to show the social impact of the Portable Light Project
    Engage
  • GogoBoard & Sensors
    Ignite
  • 3D Printer
    Ignite
  • Laser Cutter
    Ignite
  • Construct
    Students construct models and prototypes
  • Construct
    Students convert sensor information into concepts of electricity, current, power
  • Essential questions and Links to California Science Standards
    Questions to Ask
    Link to Standards
    What is DC?
    What is voltage & current?
    How to construct a simple circuit? – what are resistors and capacitors?
    What is solar power? What is power?
    How much solar energy does the earth obtain?
    What happens to the solar radiation that comes to earth?
    Electric Phenomena
    Ohm’s Law
    Voltage/current predictions in simple circuits
    Resistors & transistors
    Power calculations
    Energy in the Earth System
    Solar radiation as the earth’s primary energy source
    Construct
  • Unite
    Possible Prototypes & Products
  • Shirt with multiple light sensors, attached to Gogo Board
    Unite
    • Student wears the shirt and walks around all day
    • GogoBoard collects data on light intensity through the day
    • Can ascertain position of the solar panel for maximum light absorption
  • Shirt with solar cell attached to battery charger
    Unite
    • Student wears the shirt and walks around all day
    • Can ascertain how long it takes to charge up some batteries
  • House with variable roof angle; solar panel and light sensor attached to roof
    Unite
    • Can ascertain the amount of light obtained at various roof angles; compare with data from the shirt
    • Solar panel vs light sensor : information can be used for calibration of sensor.
