Using Mathematical Models to Investigate Planetary Habitability: Activity C The Role of Actual Data in Mathematical Models
Students explore how mathematical descriptions of the physical environment can be fine-tuned through testing using data. In this activity, student teams obtain satellite data measuring the Earth's albedo, and then input this data into a... (View More) spreadsheet-based radiation balance model, GEEBITT. They validate their results against published the published albedo value of the Earth, and conduct similar comparisons Mercury, Venus and Mars. The resource includes an Excel spreadsheet tutorial, an investigation, student data sheets and a teacher's guide. Students apply their understanding to the real life problem of urban heat islands and deforestation. The activity links builds on student outcomes from activities A and B: "Finding a Mathematical Description of a Physical Relationship," and "Making a Simple Mathematical Model." This is Activity C in module 3, Using Mathematical Models to Investigate Planetary Habitability, of the resource, Earth Climate Course: What Determines a Planet's Climate? The course aims to help students to develop an understanding of our environment as a system of human and natural processes that result in changes that occur over various space and time scales.

Materials Cost: Free per student
In this online, interactive module, students learn how enhanced Earth remote-sensing capabilities are used by dozens of satellites that are continuously collecting data from multiple vantage points. This allows scientists from different countries to... (View More) transcend political and geographical boundaries by sharing data and ideas towards the common mission of caring for planet Earth. The module is part of an online course for grades 7-12 in satellite meteorology, which includes 10 interactive modules. The site also includes lesson plans developed by teachers and links to related resources. Each module is designed to serve as a stand-alone lesson, however, a sequential approach is recommended. Designed to challenge students through the end of 12th grade, middle school teachers and students may choose to skim or skip a few sections. (View Less)

The 'cross train keeps on rollin' here in the sunny Pacific Northwest. That's right, I said sunny, it doesn't rain everyday as most people suspect. Okay, it does rain most of the winter, but weeks of insanely nice summer weather make up for it. Don't tell anyone though, it's already getting crowded here...
Enough weather talk, let's get down to business. Cyclocross business. Today, race # 2 of the Seattle Cyclocross series - not to be confused with MFG series, also underway - went down in a blaze of sunshine. I'm also fibbing a bit, race actually occurred September 30th. I'm just writing about it today, delay being working for living, family festivities - and wasting too much time on Facebook. Better late then never.
Race venue was near a small airport in Arlington, same area as the state championship held last December. Dead flat course with an interesting sand section tossed in for fun. But what do I know? I didn't even ride it - just ran around and took pictures - which has been the story this 'cross season, and will probably remain that way. I'll just say I'm semi-retired instead coming up with a list of lame excuses.
For your home viewing pleasure, assorted Pics 'N' Words to describe the day...
It's gonna be a bright, bright, sun shiny day.
My #1 son, Racer Boy Ian, looking pro in the sand section.
Ian rode the sand section every lap - nice job. While pre-riding the course and warming up, said he didn't feel too good, felt super tired, wasn't too jazzed on racing. I made the parent decision to nudge him a bit - we're already here, give it a go and maybe you'll feel better.
Good call, after the race said he felt okay and had a good time, placing 9th out of 13 kids in his class - fast kids - not easy. For this series, he races in the Junior Boys 13 - 14 class, some of which also race Mens CAT4 and do fairly well.
Teammate and junior girl racer, Ella, runs the sand section.
Junior racer recovers after crossing the finish line. Fantastic watching these kids go for it.
Furry visitor to the team tent.
'Cross requires some barrier jumpin'. Nobody said this was gonna be easy.
Under a September sun.
This dude appears to be the Seattle area race fixture, see him at every race. People call him Cosmic - hope I got that right. In any case, seems like a cool character, one of many in the local 'cross scene.
Standing on large mounds of sand gets you some interesting angles - and shoes full of sand. Here, single speed dude throws up a roost.
Junior racers do a little dirt digging after racing duty. This turned in a full scale dirt clod war that lasted forever. Good clean fun. Race turned out to be an overall fun day for Ian.
Freight train delivering the mail on the backside of the course.
Later, I constructed a scale model of the entire course in my yard...
High school racer and teammate, Theo, styling in the sand mounds.
Another high school age teammate, Harrison, plows into the sand.
Andrew powers though the sand looking pro. Later used this pic for his Facebook profile. I've had a few folks do this, which to hack photographer me, I find flattering. Much better then having a zillion pics fermenting on a hard drive somewhere.
Count the grains. Submit all entries for cash and prizes...
Cyclocross is tough. No doubt about it.
Theo in action once again. After sorting through all the pics, difficult to pick which ones to post. I guess that's a good thing. Even with the sun washed out kit, I dig this shot.
Under a glaring late afternoon fall sun, Garth blurs towards the finish.
Junior racers Mitchell, Ian, and Jarrett after a full day of dirt action fun. That's Theo lurking in the background. Cyclocross is fantastic for kids, and adults as well. Trust me on that.
Another race down in the books. Another positive experience for all. Another post for the ol' blog. Adios and good night...

Warner Bros. Wants You To 'Buy' Movies Instead Of Rent... And By 'Buy' It Means Spend More To Still 'Rent'
from the that's-not-buying dept
Rob Pegoraro, in commenting on the article, notes that oddly, the article doesn't even mention DRM in talking about why people don't want to buy from the studios or the fact that it's still much more convenient to get the content by unauthorized means. But that concept still hasn't reached the brain trust at Warner Bros., who seems to insist that as long as you can access the movies you "bought" from anywhere, people will prefer that to file sharing. While it's great that they're at least trying to add benefits, to make it more valuable and worth paying for, the whole thing smacks of someone's father trying to "act cool" for his kids' friends. Warner Bros. still doesn't seem to understand why people like things like Netflix: the convenience. Everything about Ultraviolet sounds inconvenient, and that hardly makes anyone want to "buy."
