From the Hubble Space Telescope
Activity 4A - Writing Across the Solar System
ObjectiveStudents will demonstrate their ability to synthesize what they've learned du ring the project by creating literary works of fact, fiction and/or poetry.
Ask students about various ways people learn about the sky and objects in space. If they mention only books or programs about science, help expand their horizons. Read them a few poems about the stars, or a science fiction short story, or perhaps a Native American legend about the sky. (See Resources for several easily accessible examples.) Ask them to think about how such writings complement what science tells us. Ask them to think about the social role played by story-telling under the stars, at night around a camp-fire, before there were movies and television to entertain us. Share with them some of the examples of student writing about the stars spread throughout this Guide, and on-line resulting from Live from the Stratosphere.
Tell the class that they are going to explore space using the tools of written and/or oral expression. Challenge them to reach inside themselves for feelings they experience as they look up at a starry sky or gaze at exotic pictures of other worlds in books or magazines. Don't encourage sentimentality: if you live in an urban area, and they look up and see just sky glow, ask them to write about the contrast between what they know must be out there, and what they can actually observe. If they've been moved by an Imax movie, such as Destiny in Space, or a planetarium show they can certainly jump off from there. Tell them that the only limit is their imagination.
Procedure Assign students to discussion and work teams, or have them work solo. Have them research the planets of our solar system, or other objects in the universe, using the resources suggested for Activity 1B, but adding works of science fiction (especially short stories), poetry, or legends and tales from ancient mythology (Greco-Roman, Chinese, etc.), as well as various modern and near-modern cultures.
Ask them to choose and develop a subject and a form of expression. They may wish to write a short story set in the future, or a poem about a starry night last summer. If they are interested in story-telling as oral tradition, have them make-believe they are the chief storyteller of an ancient tribe, who tonight will gather the people and tell them a story of the sky. (Hint: the names of the Constellations are an obvious starting point for stories explaining the "pictures in the sky.")
When all the students have completed their assignments, have them present or perform their works in front of the class. Class discussion can follow about how such forms of expression complement what we know, through science, about the universe. Students wishing to write a short story may set it at some point when humans have reached out to one of the HST's target planets. If so, have them incorporate what they've learned about that planet from this Live from... project. Challenge them to take into account the scientific wonders they will see, as well as the hazards they might face (intense radiation or the tedium of long-term space flight).
Some students might want to take on the challenge of writing a science fiction story in which the HST is the main character (like HAL in 2001) and the reader sees and "feels" the excitement of exploration and discovery through the camera eyes and computer brain of the HST itself. How does the Hubble "feel" when these humans periodically come and go, doing eye-surgery, prodding and poking, and then leaving until the next servicing mission? How does Hubble feel, sharing the starlight with these puny, so-called astronauts, when it's he/she (there's a discussion to be had right there!) who's the true seer for the humans down on Earth?
Sharing student work via on-line Kids' Corner
Many of the Activities in this Guide provide opportunities to integrate technology in teaching and learning through the use of computer-based art, word processing, desktop publishing, and multimedia applications. Passport to Knowledge invites educators to submit student work to be shared on-line via Kids' Corner, a gallery of student creativity from participating classrooms. Be sure to save your students' work to Mac or IBM diskette, and clearly label file names, content, teacher, grade, school, full address, phone number, and other relevant background information. Send the diskette(s) to:
Marc Siegel, NASA Ames Research Center, Mailstop T-28H, Moffett Field, CA 94035
Student-created image and text files will be added to Kids' Corner as appropriate. Individual student e-mail addresses will not be included. Student name, school names, location, grade level will be cited, unless requested otherwise.
Activity 4B: "Lights... Camera... the Universe"
ObjectiveStudents will collaborate and demonstrate the ability to use research, writing and presentation skills to create a multimedia report based on HST observations of the solar system or the Universe at large.
Ask students to think of ways that images and sound work together (TV commercials, videos on MTV and VH-1, animated and feature films). Ask them to think about how and why directors and writers compose words, music and pictures as they do. Say their homework is to become students of the media, to become media-literate. Tell them they will then have a chance to become multimedia authors, producers and directors, rather than passive consumers.
Do such works sometimes take their audience to places that are impossible to visit by any current technology, to a "Land before Time," on voyages of the Starship Enterprise in a future yet to come? Help them differentiate between fact and fiction, between science documentaries and dramatic imagination. Tell students of the impact made by works of fiction, such as H.G. Wells' War of the Worlds and Jules Verne's fictional trips to the moon, on the inventors of modern rocketry. Like art and science, fact and fiction are sometimes complementary. The trick, however, is always to know one from the other when it counts!
/Encourage students to research the subject by looking at illustrated articles in magazines such as Odyssey, Astronomy and Sky & Telescope, as well, perhaps, as TV shows such as Star Trek or Babylon 5. Have them write and present an analysis of a piece they find compelling. Remind them that they are watching TV to learn ways in which images articulate the story. You can order slide sets by famous space artists for your class: see Resources for other suggestions.
Have them select a genre for their work. If they choose realism, challenge them to research the science behind the scenes they're going to create. What physical processes are at work? Does their planet have huge storms, gigantic lightning bolts or other interesting features? (see Activity 3C for a list of interplanetary weather.) How can this be effectively shown? If they choose fiction or fantasy, challenge them to develop a coherent, detailed vision of a world. What is this place like? How does it resemble or differ from our own world? (Space artist Adolf Schaller conjured up "Hunters, Floaters and Sinkers," hypothetical life-forms which might exist in the clouds of Jupiter, and an entire ecosystem of hunters and prey: fantasy, sure, but based on substance. Encourage similar creative leaps.)
Procedure Have the students form creative teams. Each team will create a presentation utilizing no more than 2 minutes of music, and no more than 24 slides. Ask each team to pick a planet, and search books, magazines, and Internet sites, for pictures of that planet and its satellites.
Show students how to make slides of these pictures and images by properly pointing and focusing the camera. Don't use flash. Do use a tripod! Suggest they photograph books and magazines outside, or near a daylit window in indirect light if they are using film that is marked for daylight use. Photograph images from a computer screen in a darkened room to reduce glare.
As they are considering the pictures they'll use, have the students also listen to music for their presentation. Ask them to think about what type of music comes to mind when they look at the pictures, but encourage them to experiment with different kinds of music. Expose the techno fans to Holst, and the violinists to rock. But let them end up feeling that the choice is fully theirs.
When the Big Day arrives, have the teams of students introduce and perform their presentations. Depending on the social dynamics of your class, you might want to have a "Golden Planets-Students' Choice Award" for the "best" in the various categories.
If some students enjoy playing musical instruments, or creating music, allow them to tape their own music for the audio portion of a presentation.
Suggest to the Principal that your students might present to the school, to lower grades, to a PTA meeting (especially if your department needs extra support funds!), to the school board, if it has questions about just what those modems and computers do, or to local citizens on election day. Your students will gain confidence in themselves as authors, as teachers, as well as learners.
Have your students investigate the world of Space Art in greater depth including the International Astronomical Artists' Association and NASA's Artist in Space program. Discuss the role that art plays in our exploration of space and our attempts, as human beings, to better understand how we fit into the "big picture" called the Universe. Review your students' work for Activity 4A or 4B. What knowledge, concepts, processes, skills, attitudes, do you see evidenced there which you can attribute to their involvement in Live from the Hubble Space Telescope? How does this relate to your school, district, state mandates, or course of instruction. Now turn to the Teacher Evaluation Forms, fill 'em out and send 'em in... and 500 of you will receive a free copy of NASA's Astronomy Village CD-ROM.
Lastly, assemble copies of your students' work, on paper, videotape, or computer disc, and ship to Passport to Knowledge, P.O. Box 1502, Summit, New Jersey 07902-1502, clearly indicating whether you need the materials back, and whether we have permission to use them for project evaluation. PTK hopes to create its own multimedia report on the new territories of knowledge and imagination your students have been exploring.
Activity 4C - Hubble in the Headlines
ObjectiveStudents will demonstrate the ability to discuss and debate the value to society of major scientific and technological enterprises such as HST.
Passport to Knowledge feels privileged to have helped construct this unprecedented bridge between students and the Hubble Space Telescope. (Review LHST Program 1, "The Great Planet Debate") Explain what a truly world-class facility the Hubble is. As you'll learn from LHST, the Hubble was much in the news in early 1996, with a whole range of discoveries. Incredible numbers of faint galaxies were detected where none had been seen before. Spectacular regions of star birth were visualized in astonishing detail (as on the co-packaged poster); and planets were detected around distant stars. By getting their "virtual" hands on the Hubble, your students become members of a very select group of astronomers and scientists.
Tell students that when Hubble was first launched, astronomers were horrified to learn an imperfection in the construction of the mirror meant images were out of focus. Some in the press and public wrote off the Hubble and "big science" as too expensive, risky, and complex. Efforts by workers at many institutions in NASA and outside the agency-some of whom your students will "meet" on-camera or on-line-placed corrective optics and a new camera system (which we are using to image Neptune) aboard the Hubble, in the first of several always-planned servicing missions. Now Hubble's eye is crystal clear, and the science it had already accomplished took off.
Procedure Have students research the 1995-1996 Hubble discoveries, especially those not yet in textbooks: use on-line services, and current magazines. Tap libraries for books about HST which describe its initial problems, and the technical fixes which have made it the superb tool it is today. If you have access, download some of the discuss-hst archive, and see students' initial reasons for wanting to observe specific planets. Review our Planet Advocates' eloquent comments: how studying impacts on Uranus can give clues to the evolution of life on Earth, or how weather on Jupiter or Neptune can reveal new information about our own planet. Marc Buie is concerned with vision and human destiny, as well as scientific knowledge. He argued that our species always looks to new frontiers, such as Pluto, the only planet in our solar system not reconnoitered by our spacecraft, and that this is what keeps young minds and imaginations ("lifelong learners of all ages") engaged and growing.
Brainstorm these issues with students: elicit their opinions, provoke their comments. Group them into teams, based upon natural inclinations ("pro" or "con" Big science and projects like the Hubble), and have them research their opinion for a formal in-class discussion or debate. Remind them that in debate, success often comes to those who understand the best arguments of their opponents, not just their own.
Stage the debate. Record the arguments on audio or videotape. Have students edit the "official transcript" for the school, or local newspaper. As with Activity 4B, look over your students' arguments. What knowledge, concepts, processes, skills, attitudes, do you see evidenced which you can attribute to their involvement in Live from the Hubble Space Telescope? How does this relate to your school, district, and state mandates, or course of instruction. (Again, please turn to the teacher and student evaluation pages and fill 'em out and send 'em in.)
