"Saturday Discovery" Youth Programs in the Planetarium

For many years the Workforce Development & Continuing Education division of Montgomery College has been offering  "Saturday Discovery" youth programs.

On Saturday, March 24, 2007 4 sessions of 1 hour and 15 minutes each were held in the planetarium.   A star show and PowerPoint presentation titled "The Dwarf Planet Pluto & New Horizon" and we built a comet analogue outside using: 1) Dry Ice, frozen Carbon Dioxide, CO2; 2) Water, H2O; 3) Builders sand, Silicates mainly SiO2; 4) Charcoal, largely Carbon, C; 5) Dark Karo Syrup, complex hydrocarbons; 6) Little Ammonia, NH4; 7) Frozen Methane, CH4, not used for safety sake (it burns and explodes in air), but it looks like  CO2 and has similar material  strenghts.
 
On Saturday, March 18, 2006 4 sessions of 1 hour and 15 minutes each were held in the planetarium.   A star show, and we built equatorial sundials from scratch with a protractor from a file folder.  We will also assemble a horizon sundial and an analmatic sundial on the same card.   With a horizon sundial and an analmatic sundial on the same card designed for the latitude correctly, around 39 degrees here in the Washington DC metro area, you just rotate it and when the two shadow casting gnomes of each sundial read the same time, you have found the time and the cardinal directions, north, east, south, and west.  So this device is both a clock and a direction finder. Simple Sundials the Microsoft PowerPoint presentation.

On Saturday, November 12, 2005.  4 sessions of 1 hour and 15 minutes each were held in the planetarium.   A star show, a walk of the planets (scale model of the Solar System, the "Earth as a Pepercorn or the Thousand Yard Model of the Solar System"), and a Power Point presentation were presentation on the "Scales in Space and Time in the Cosmos" was held.
