"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.
