A year ago today everyone was talking about and viewing the eclipse

Observing science "live" is an important piece of learning, asking questions, being curious

A year ago today I was very fortunate to be part of a NASA sponsored team launching high altitude balloons in Idaho to record data about the total eclipse.

This is the shadow of the Moon from about 23,000 meters (75,000 feet) above Camas, Idaho

Meantime back in northern Nevada where I work, thousands of students and members of the general public were using the tens of thousands of eclipse glasses science educators had acquired and passed out to local schools. The eclipse in Nevada was not total, but it was still a site to see.

The eclipse took the nation by storm and millions took to staring into the sky and learning about what was really happening. When we got back from our Idaho trip we processed the photos, video and data and made it available to anyone that wanted it. We also shared the experience with students and teachers when we did teacher trainings or classroom visits. Students and teachers would not only express awe at watching our video of the Moon’s shadow moving across the Earth’s surface, but eager hands would shoot up begging to share their own experiences watching the eclipse and the various ways they monitored it.

Providing access to experiences like eclipses, but also snow falling, or a thunderstorm or leaves changing color in fall and then allowing students to unpack them, express their awe and interest and even giving the time to research on their own are great ways to have students utilize technology to learn. Having students then publish their learning and photos and other media through blogs, photo sites, web pages and other places is where edtech is at its best. If your students are mainly doing everything Google and only publish in house or to your classroom walls you might want to consider publishing to the world to leverage the motivation to learn and polish what they publish in creative, expressive ways.

Learning is messy!

Photos, Video and DATA from the Eclipse Balloon Project

I’ve been back for awhile from our Eclipse Balloon Project launches. We’re still processing data we recorded from cameras and data loggers from 3 HAB balloon launches outside of Twin Falls, Idaho, (really from Camas, Idaho), but wanted to share some of the incredible visuals. Click on any photo to see enlarged.

The prediction was very accurate – this is actually 10 predictions on one screenshot – yellow dots are predicted burst and blue predicted landing spot:

I did send up a small solar panel attached to a voltage data logger. We usually do this to record data on what happens to the voltage as the panel gets higher and much colder. But this is interesting for obvious reasons:

 

Note the voltage goes up as the altitude rises over time … then “something happens” that causes the voltage to drop to almost zero.

This balloon came down within sight of a temporary command center of sheriffs and other emergency personnel that had been set-up to help with the crowds and any issues that may have arisen. You’ll note that at the end of the data it seems to have gotten dark again. The sheriff investigated what had landed  nearby and picked up our payload and placed it in their command vehicle until we showed up. Once we had described it they briefly handcuffed Dr. Wang and I for endangering the public … then had a good laugh and took the handcuffs off.

Dr. Eric Wang and I handcuffed with our payloads in hand.

 

 

 

 

 

 

 

 

 

Nothing too surprising about our temperature readings – at 28,000 meters (92,000 feet) it was about -42C :

 

 

 

 

 

 

 

 

I have other data as well I might post later.

We successfully launched 3 balloons – one got to over 110,000 feet, but we also had 2 balloons pop on the ground during and just after inflation – one seemed defective, the other probably got stressed in the relatively high winds at the launch site and popped just as we were connecting payloads. Fortunately we had enough gas to fill 2 more balloons.
