PreviewFor Volunteers Balloon Fest is a Regional Interscholastic STEM EventTeachers and teams of 3 to 6 students are invited to launch helium-filled, tethered balloons with student-designed instrumentation in order to measure different characteristics of our atmosphere, or to test alternative engineering designs.After weeks of preparation, at an exciting all-day event, students will gather data, analyze it, and present their findings to peers, parents, and professionals.Enthusiastic adult mentors, judges, and event volunteers provide encouragement and active support for these student teams.Levels of ParticipationLevel 1                               Introductory   Designed for first time experimenters, ES or MS.

  • Two Options
  • Science
  • Engineering
  • Examples: Science
  • • Altitude Profiles:
  • a. Barometric Pressure
  • b. Air Temperature (Temp. Inversions)
  • c. Humidity
  • d. Ultraviolet exposure
  • e. Cricket activity levels
  • f. CO2 or O2 %
  • g. Magnetic Intensity
  • h. Electric Field strength
  • i. Cosmic Ray Flux
  • j. Sound frequency attenuation vs altitude
  • Constant sound generator, microphone, oscilloscope with fourier analysis, printer and computerExamples: Engineering
  • • Find the point directly below the balloon
  • • Parachutes, Egg drop, Glider design
  • • Minimum Aneroid Barometer device to determine maximum altitude One-way valve to allow air out will sample lowest pressure if T is const.
  • • Trigonometric Altitude measurement Two or three base stations, solid geometry, simultaneous measurements
  • • Aerial Pictures or wireless Video for altitude measurement
  • Interesting perspective but also ability to measure altitude by apparent size of image
  • • Remote Sensing
  • AIRSS: Crop Vigor
  • • Comparison of altitude measurements by barometric pressure, line
  • length & angle, Laser rangefinder, GPS, Trig, and plate scale. Precision & accuracy. • Release and track a balloon to measure air movement vs altitude.Small Satellites for Secondary StudentsKevin JohnSonoma State UniversityEducation and Public Outreach GroupThis work has been supported by NASA Grant NNX12AB97GStandard payload designPower ConnectionServoAccelerometerGPSHumidityWiFi SD Data LoggerArduinoPressure and Temperature MagnetometerTop ViewBottom ViewBalloon Fest 2012 payload testsAntenna configuration tested during Balloon Fest in December 2012 at Allan Hancock CollegeBalloon Fest 2013 payload test
