If you want keep up with what is happening at the ASP’s Annual Meeting on astronomy education and outreach running from today to 16 Sep at Millbrae, near San Francisco there should be a few blogs providing updates. I’ll try and do at least a daily post. Pamela Gay of Star Stryder already has a post up. Hopefully the Half-Astrophysicist will post some updates too. Please let me know of any others. For those on twitter search for updates on #asp2009.
Galileo Teacher Training Program Workshop – Day One September 14, 2009

I’m in San Francisco for the ASP’s Annual Meeting on astronomy education and outreach. Prior to the three-day meeting I’m participating in a 1 1/2 day workshop for teachers, one of the first Galileo Teacher Training Program (GTTP) workshops held in the US. The workshop participants are mostly school teachers, some at elementary (primary), some middle school and some at high school. A few teach at community colleges then there were also a few of us astro ed professionals or spies as we were introduced as.
The day one presenters were a highly experienced bunch; Dennis Schatz from the Pacific Science Center, Andrew Fraknoi from the ASP and Foothill College and Rob Sparks from NOAO (read his blog here). Andrew started with and icebreaker activity where we all introduced ourselves then gave us an intro to Galileo followed by an overview of the realms of the Universe, working out from the Solar System to the Milky Way then beyond. We then tackled a fun activity: Bill Gates’ Great Great Grand-daughter’s Honeymoon Trip” 10 Tourist Wonders of the Solar System. Lots of discussion about the best tourist sites in the Solar System.

Dennis then gave asession on elements of effective instruction. He showed a segment from the influential film A Private Universe highlighting misconceptions by Harvard graduating students, faculty and alumni and with school students. He stressed the importance of identifying students’ preconceptions, using advance disornaizers, and analogies. Connect into real-world experiences, embed on-going assessment experiences and encourage them to reflect on their understanding with others. After morning tea Dennis continued with a session on modelling lunar phases. I found his demonstration using hula hoops of why eclipses don’t occur each month really handy and one I will try to use from now on.
After lunch Andrew introduced an activity for students to replicate Galileo’s observations of the moons of Jupiter then Dennis showed how to build a starwheel and use it within a classroom with constellation images on butchers paper on classroom walls, another great idea.
Using laser levellers and a vellum screen.
The final part of the day was presented by Rob Sparks. Every participant received their own Galileoscope! Rob showed us some effective optics demonstrations using large lenses, vellum screens and laser levellers. Spray fog reveals laser beams clearly as you can see in the photo below. We used the new construction instructions available from the Galileoscope website to build our scopes. Along the way we were able to measure the focal length of the 50mm f/10 objective lens. It was interesting to compare the difference between the 4-element eyepiece and the two-element Galilean eyepiece. The narrow field-of-view of the Galielan eyepiece makes you appreciate his skill as an observer.

Overall it was a really useful and stimulating day! Lots of ideas and activities for me to incorporate into my workshops back home.

The Big Aussie Star Hunt website now shows the winning entries in the rename a constellation competition.
Go have a look for the two winners. Very nice!
Astronomy Education at the ASP Meeting September 10, 2009

I’m off to San Francisco tomorrow for a week of astronomy outreach, education and teacher workshops. The main event is the Annual Meeting of the Astronomical Society of the Pacific with the theme: Science Education and Outreach; Forging a Path to the Future. Workshops and discussion will focus on building on the success of the International Year of Astronomy and planning for the future. Focus questions are:
- IYA: Can We Keep the Party Going?
- Year of Science: Will Science “Speciation” Endanger Science Learning or Enhance it?
- Refining our Practice: Can we Really Make an Impact?
- The Future is Here: Can EPO Navigate the Digital Age?
A variety of workshops and some great keynote speakers should provide plenty of stimulation. I hope to be able to post some updates during the meeting. I’m presenting a poster about IYA activities during National Science Week in Australia then an oral presentation: Building Education Programs for ASKAP.
Prior to the meeting itself I’ll be attending two days of teacher workshops. The bulk of this will be for the Galileo Teacher Training Program which I hope to implement here in Australia. The Sunday afternoon is a special session; “SETI Speaker Series featuring scientists and researchers from the SETI Institute in Mountain View, California. Speakers include Drs. Frank Drake, Seth Shostak, Margaret Race, and John Jenkins”. Should be interesting!
Great Movie of ATCA Reconfiguration September 2, 2009

Here’s a great question for trivia competitions.
Q: What is Australia’s widest gauge track?
A: Forget those massive iron ore trains in WA, Australia’s widest gauge track is actually in Narrabri, northern NSW at the Australia Telescope Telescope Compact Array (ATCA), part of the CSIRO Australia Telescope National Facility.
ATCA is a radio telescope, an interferometer comprising 6×22m dish antennas. Five of these are on a 3km long E-W track with the sixth antenna a further 3km away. Five antennas can be placed at different locations along the track to vary the baselines between all the antennas. An advantage of radio telescopes is that separate antennas can be linked together electronically to simulate a telescope equal in size to the maximum baseline distance. This increases the resolution of the telescope, that is the ability to see fine detail. Having multiple antennas provides great collecting area, hence higher sensitivity, than just two antennas. It also improves what radio astronomers call u-v coverage. Over a long observing run, typically 12 hours, the signals from each antenna can be correlated to from an image in a process known as Earth-rotation synthesis.
Every month or so the antennas of ATCA can be reconfigured to new spacings. One or more of the five antennas on the track are driven to a new position then jacked up off the track to mounts. The electrical systems and fibre optics are then reconnected and the telescope is ready for operation with a new configuration. To see what happens in a reconfiguration have a look at this great movie below showing a 1 1/2 hour operation in just over 2 minutes!
The movie was made by one of the ATNF astronomers, Dr Emil Lenc during a recent reconfiguration. It was compiled from 2877 photos taken over 1.5 hours.

Due to cloudy weather over much of Western Australia this week the ABC has just announced an extension to the Big Aussie Star Hunt. You can now observe Scorpius and enter your results and competition form on the website before midday Monday 31 August. Every observation logged puts you in the draw for $2,000 of goodies from the ABC Shop.
Fortunately my viewing night in WA last night was clear of clouds and absolutely stunning. Hopefully I’ll have some pics to post soon.

Seems I was rather slow posting about Carnival of Space #115 last night. Carnival of Space #116 is now live at Habitation Intentions. Lots of interesting things to read and view.
Science Week in Geraldton August 17, 2009

I’ve got a busy week ahead of me. I’m flying over to Geraldton in Western Australia for a series of events as part of National Science Week. Tomorrow I’m giving several talks to students at Nagle Catholic College in the afternoon followed by some professional development for teachers in the region and, hopefully, a viewing night.
The following morning I’ll be up bright and early as I have an on-air lesson about telescopes with students from the Meekatharra School of the Air. After that I drive out a few hours to Yalgoo (the first town in the Outback) where I’ll be taking part in a viewing evening for students from three schools, Yalgoo, Pia Wadjarri and Sandstone, who have come together for a few days for their athletics carnival. I’ll be joined by Megan Argos from Curtin (AstroMeg). We plan on getting the students to take part in the Big Aussie Star Hunt, the national project for Science Week.
On Thursday I’m giving a public talk about the life and work of Galileo at 7.30pm in the Queen Elizabeth Theatre prior to Theatre Eight’s production of Brecht’s The Life of Galileo.
It should be a busy but fun and rewarding week. Hopefully I’ll get some photos and more information up about the various events later.
