  1. Science EngagementIn and Out of the Classroom Mike Davis Interim Vice President for Academics Wilbur Wright College

  2. Science Demonstration Liquid Nitrogen Content / Context • Very cold liquid • 77K (-196 C) • Boiling at room temperature • Rapid converts from a liquid to a gas • Causes rapid condensation from atmospheric water.

  3. Science Demonstration Liquid Nitrogen Demonstrations Liquid nitrogen in a clear plastic bag. Liquid nitrogen in a black plastic bag. Liquid nitrogen in a sealed container. Liquid nitrogen and graham crackers.

  4. Science Demonstration Chemical Luminescence Content / Context Same concept used in glow sticks. Production of light from chemical reaction. Exothermic reaction Conservation of energy through fading.

  5. Chemical Luminescent Fountain Glowing Fountain Demonstration Combination of two liquids. Use of atmospheric pressure. Pressure Balancing.

  6. World’s Largest Periodic Table of the Elements

  7. Periodic Table Sold sponsorships for individual elements. Iodine Curium Krypton Gold Installed the table in one night. Stayed up for one week. Launched the 2006 Chicago Science Expedition “2 Weeks Worth of Wow!”

  8. Next Big Thing Raspberry Pi STEM Social • ScienceFIST & Google • Gave away 60 RPi computers • Teachers • After School Providers • Cost $25 and can be very configurable. • Open source software and hardware.

  9. Why was this impressive The table was up for one week, and was featured in Chemical & Engineering News, and all local news outlets. Launched city-wide science celebrations in 2007 and the 2008 Year of Science from MSI. Check out this guy.

  10. Science Demonstration Atmospheric Pressure Content Context • Air pressure • 14.7 lbs/in2 • Counter intuitive demonstration. • Exactly the same as the luminescent fountain.

  11. Index Matching Hydrospheres Disappearing Spheres Context / Content • Index of refraction • Water absorbant • Absorb other molecules! • Sugar • Base

  12. Performing Science Demonstrations The Audience American Science & Surplus Middle School Students Parents / Teachers Television AAAS Family Days Museums Libraries
