Objectives
Provide space weather resources and professional development for grades 6-14 teachers
Integrate CISM research and education
Leverage off Center concept and engage CISM scientists with the educational program
Respond to diversity needs
4
The Plan
Team community college & high school educators with scientists to:
Design, develop, & classroom-test VLF radio receivers that track changes to the Earth’s ionosphere caused by solar activity
Provide Standards-based, hands-on, inquiry-driven science experience for teachers and students
Return data useful to researchers Involve high school, undergraduate (incl. community
college), and graduate students
Involve researchers
5
How?
Based on AAVSO original concept 2 versions:
SID – inexpensive (~$150) AWESOME – research quality (~$3000)
Preassembled, but students build their own antenna (~$10)
Centralized data repository & chat site
6
Are placing 100 SIDs and 15 AWESOMES in under-represented high schools,
community colleges, & science museums
Leverage from CISM Education Partners Teacher workshops (NCAR) University application (Alabama A&M) Integration into teacher-training courses (Rice U.) Development of web-based training (Exploratorium, NCAR, Stanford)
Engagement from CISM Science Partners: Distribute in a Partnership model, to encourage scientist-teacher-student
collaborations Return data to CISM and other researchers
All materials standards-based
Professional formative & summative assessment
Obtained supplemental funding from NASA

It takes a Center…
Space Monitor program leverages off Center concept
Provides coherence – interconnection with multiple partners and varied programs
Integrates research and education
9
Educator Professional Development
NCAR provides professional development workshops, in person and online, about space weather topics to teachers – these will be modified to include the Space Weather Monitors
Rice U. will be integrating the monitors into their Physics of Ham Radio course for teachers.
Alabama A&M will be integrating the monitors into their space science program

IHY 2007
The United Nations and organizers of the International Heliophysical Year, 2007, have designated these Space Weather Monitors as official IHY instruments, to be placed in 191 countries around the world.

Overview of the Monitors
The Sun & Earth’s Ionosphere VLF Transmitters About our monitors Data & tracking Connecting monitor data with GOES Connecting data to solar active regions
13
The Sun, ionosphere, and radio waves
14
VLF Transmitters
200’ Towers
Antenna Wires24 around the world
“NLK” 24.8 KHz Navy Radio Station, Jim Creek, WA1 cycle = 7.5 miles (12 km)
VLF signals can be received all over the world, because of the ionosphere!
Primarily U.S. Navy stations for communicating with submarines
15
Our Monitors
SID Low Cost (~$150) Single band 1 sample/5 seconds Preassembled & tuned Students build antenna Available free to
underserved schools
AWESOME Moderate cost (~$3000) Broadband; sample rate of
100kHz on each channel Capture ELF/VLF frequencies ~30 Hz - 50kHz Dual use system: Daytime: monitor solar activity Nighttime: monitor atmospheric
phenomena (e.g. lightning) So sensitive that nearly any
signal above the ambient Earth noise floor can be detected
Data useable for ionospheric and solar researchers
