If your school has one or more computers located outside your classroom, students may experience the lesson individually or in small groups as a learning station. Some students might have computers at home with access to the Internet. If that's the case, you might consider assigning sections of the Comets activity as homework or extra credit. NASA offers FREE comet and Solar System-related lithographs and posters, which are available at your closest NASA Educator Resource Center. They can be used as teaching tools in the classroom.
Parents can preview the different lesson modules and examine the teacher pages ahead of time.
A wealth of information related to astronomy also can be found at the home page of the Space Telescope Science Institute . Here you can find background information on the Hubble Space Telescope, pictures, news releases, educational activities, and other science resources. The Homeschooling Handbook.
