Popular music lyrics have been used to introduce students to poetry (Brenda Guerra has a nice lesson plan on the subject). We recently had an overnight at the school and the students elected to play Rock Band. It was clearly indicated that the songs they played would have to have language acceptable to the Middle School. Among the song choices they made was Bon Jovi’s “Living on a Prayer”.
I’d considered “Living on a Prayer” as one option for poetry reading but rejected it because I wasn’t sure that lines like, “she brings home her pay for love” would be quite appropriate. What I found most interesting was that even though they sung the song, they did not actually know the words. The game appears to only require them to make sounds of the right length and maybe pitch. So the singing sounded like, “Tommy used to blah blah blah blah.”
So now I think I’ll use the song, but I’m curious to see the response. Will the fact that it’s something they are aware of and play in a game make it more interesting to them? Or will it work the opposite way? We’ll find out.
This song also introduces issues of unions and the way the arts reflect society, both overtly and, in this case apparently, hidden in the music.
We read that temperature is the average kinetic energy of a substance but you can (especially if you’re a visual learner) nicely internalize this from simple videos or animations. UCAR has a little animation with their definition of temperature. I however, adapted an interactive, 3d animation that I think does a nice job, and also introduces a couple of other interesting concepts too.
I’ve also used this model, at different times, to show:
The relationship between temperature and color emitted by objects. The main way we know the temperature of stars is because blue stars are hotter than red stars. Blue light has a shorter wavelength than red light, and things that are at higher temperatures emit shorter wavelengths.
Absolute zero (0 Kelvin) – where (almost) all motion stops and the objects stop emitting light.
Pressure in a gas – you really get a feel for the force exerted by the particles on the side of the box (although it might be even more interesting once I figure out how to add sound).
It is an interactive model, but it’s pretty simple because the only control is a slider that lets you set the temperature.
Finally, in the age of 3d movies, like Avatar, the models can be easily shown in 3d if you have the glasses (redcyan).
The model is easy to install and run on Windows, but you have to install the programming language VPython separately on a Mac (but that isn’t very hard). I have this, and a bunch of other models, at http://earthsciweb.org/GeoMod/.
I discovered science fiction in my early teens but it was always hard to find the great stories in the midst of a lot of drivel. This list of 100 good science fiction and fantasy books seems to be a good start. Most of the books on the list are worthy, but it completely misses John Wyndham (The Chrysalids among others) and Brian Stableford (e.g. War Games). There are also a few that bored me to tears (Bradley’s Avalon) and some that I did not think were very well written (Crichton’s Sphere).
I like science fiction because it tends to deal with some of the big issues that adolescents are facing. Who am I, what’s the future going to be like, what does it mean to be human, what’s my place in society, and of course, wouldn’t it be nice it everyone just disappeared and I had the world all to myself? You also get to tie it in to the Natural World and Social World curriculum.
The Chrysalids is a great example. A post-apocalyptic novel, it looks at, among other things, institutional discrimination, the conflict between science and religion, and evolutionary theory (with it’s darker side eugenics). Wyndham addresses these issues with interesting characters and wonderful, intelligent storytelling (with a heroic journey). I’ve used this book as part of the life sciences curriculum for the tie-in to evolution, and to the history of the Cold War. But I also bring it up when we discuss human rights and discrimination.
The Voyager spacecraft, launched in 1977, are still going and making new discoveries. They are after all the man-made objects that are furthest away from the center of the solar system, beyond the orbit of Pluto, and are now approaching interstellar space.
Where does the solar system end and interstellar space begin? Well, the Sun gives off light, but it also emits a plasma of charged particles (protons and electrons typically) that’s called the solar wind. These charged particles are launched from the Sun pretty fast, but as they get to the edge of the solar system they start to slow down, because the solar system is moving through a magnetic cloud, and, as we all know, charged particles are affected by magnetic fields.
The solar wind, assisted by the Sun’s magnetic field, pushes against the interstellar magnetic cloud, creating a bubble, called the heliosphere (helio=sun, sphere=sphere) that is pretty much the edge of the solar system.
Both Voyager spacecraft are approaching the heliosphere, and we’ve recently discovered that as the solar system moves through the interstellar magnetic cloud, the heliosphere is pushing against the cloud and the cloud is pushing back quite a bit. As a result, the heliosphere is shaped like the bow wave of water around a speeding boat.
It is difficult not to personify these two lonely spacecraft as the get further and further away from home, with no way to get back, but sending signals that tell of their discoveries and ensure their immortality.
The plight of Haiti is on the front pages with the latest disaster. Starting with the first and only, I believe, successful slave rebellion, the nation was founded with such promise. Sadly, however, most of Haiti’s history since then has been tragic. A series of disfunctional, corrupt governments were not helped by almost continuous intervention by the European and American powers. The result, the poorest nation in the Western hemisphere. David Rudder, a Caribbean song writer and singer, captures the sadness of this history and the current abdication of responsibility of its neighbors in the song Haiti.
… this was the first Republic in the New World. The first free Republic and led by a slave. You can’t get more intense than that and look where it’s at now. … it’s also saying to people in the Caribbean that we were brought here on the same ship, but the English speaking Caribbean does not know what is going on in the Spanish speaking Caribbean and vice versa or the French speaking Caribbean. We are looking outwards to different places and at the end of the day all we have is ourselves. The wider societies don’t really have time with us again.
Io over Jupiter taken by NASA's Cassini spacecraft.
400 years ago, on January 7th, Galileo Galilei made his first observations of Jupiter. You can see his notes below. The big circle is Jupiter and the small dots are the specks of light he observed adjacent to the planet. Later observations showed that the specks did not stay in the same place, and lead him to realize that he was seeing moons orbiting the planet.
Galileo's notes from Jan 7, 1610.Translation of Galileo's notes (from NASA).
Galileo used a 33x telescope, which is pretty weak by modern standards, in fact you should be able to see Jupiter and it’s moons with a good pair of binoculars. Since the Catholic church at the time preferred the view that the Earth was the center of the universe, when Galileo published his observation he got into a bit of trouble. In his publication Galileo wrote:
On the 7th day of January in the present year, 1610, in the first hour of the following night, when I was viewing the constellations of the heavons through a telescope, the planet Jupiter presented itself to my view, and as I had prepared for myself a very excellent instrument, I noticed a circumstance which I had never been able to notice before, namely that three little stars, small but very bright, were near the planet; and although I believed them to belong to a number of the fixed stars, yet they made me somewhat wonder, because they seemed to be arranged exactly in a straight line, parallel to the ecliptic, and to be brighter than the rest of the stars, equal to them in magnitude . . .When on January 8th, led by some fatality, I turned again to look at the same part of the heavens, I found a very different state of things, for there were three little stars all west of Jupiter, and nearer together than on the previous night.
Jupiter is much blamed by the poets on account of his irregular loves. Three maidens are especially mentioned as having been clandestinely courted by Jupiter with success. Io, daughter of the River, Inachus, Callisto of Lycaon, Europa of Agenor. Then there was Ganymede, the handsome son of King Tros, whom Jupiter, having taken the form of an eagle, transported to heaven on his back …

With open classrooms allowing lots of movement, we don’t often have to deal with issues of seating arrangements. But, an interesting study (from back in 1993) found that students (adults in this case) who sit on the right side of the room are more right-brain oriented. They tend to be more the artistic types, less cautious in responding and less analytical. Right side sitters also scored higher on femininity on a Masculine-Feminine scale.
Since we’re creatures of habit, I wonder if we can see this pattern in the seating arrangements for lessons and community meetings. On balance though, I’d think this would be another argument (if another was necessary) for allowing students and lots of movement so there is more mixing and sharing of talents.
Why have I not found this site before, Evil Mad Scientist Laboratories. A place where people will put serious thought, rigorous design and atrocious single-mindedness to create, well I’m not sure I can call it anything other than, “very interesting” projects. Applications of robotics that would make Asimov cry (probably with joy at human ingenuity, probably).
They carefully detail how to create such wonderful projects as:
