• Description / overview of the lesson:
  Join Professor WifPic in examining the Hubble Deep Field image and simulate the process astronomers have gone through to count, classify, and identify objects in the image as well as estimate their distances from Earth. The lesson is modular so that all or part of it may be completed using computers and the Internet.

  A hard copy version of the lesson will be available in the Grab Bag for those who do not have Internet access.

• How to Prepare for an “Online Exploration”

  Decide if the activity meets your needs.

  1. Check out the activity ahead of time by working through it as your students will. As you go through the activity, pay attention to the following:
  • How to navigate from one place to another.
  • The ability level. Can students work this activity successfully?
  • Natural breaks within the activity. Is there enough flexibility that students can complete all or selected parts within the time restraints of the daily schedule?
  2. Check out the “Teaching Tips” for the following information.
     • Overview: Serves as a broad, comprehensive summary of the activity, including a description, the concepts covered, prerequisites, and the target audience.
     • Science Background: Provides information about the science behind the activity. It clarifies important concepts used in the activity and contains a message from the scientist who worked with the team to develop it.
     • Lesson Plan: Addresses specific recommendations for using the activities, including learning outcomes, new vocabulary, misconceptions, engagement activities (under the heading procedure/directions), and follow-up activities. Includes suggestions for using the activity in one-computer classrooms and those without computers.
     • National Standards: Provides alignment between the activity and the National Science Education Standards, the National Council of Teachers of Mathematics Curriculum and Evaluation Standards, and the Project 2061 Benchmarks for Scientific Literacy Standards. Many state and local standards were developed from these so it should be easy to check for correlations.
     • Grab Bag: Provides resources for educators who wish to customize the activity. Includes images from the activity, which can be used to develop your own interactive lesson. Also identifies resources used in the activity and others related to the topic, which can be used by students and educators to do further research.

  Before using the activities...

  1. Check out your computers.
  • Review the Computer Needs section of the activity.
  • Reserve a time to use the computer lab.
  • Bookmark the activity on the Web browser (Netscape Navigator or Microsoft Explorer) of each student computer.
  2. Determine a strategy for organizing your students. Options include the following:
  • Use a whole-class approach with one computer.
  • Use a team approach in a computer lab, with different students having specific responsibilities during the activity (such as “mouse user,” “note taker,” and “oral reader”).
  • Use a one-computer-per-student approach.
  3. Think about how this online activity matches up with teaching materials that are already available to you. These might include:
     • Curriculum guides
     • Textbooks
     • Videos
     • Posters
     • Labs

  Preparing students

  1. Share the objectives and the key vocabulary words used in the activity.
  2. Use a large monitor, LCD, or transparencies to give a preview of the activity and to demonstrate how to navigate within it.
  3. Give your students a computer/Web pre-assessment to determine their computer experience and/or competence.
  4. Organize your students in such a way that more experienced users are matched up with less experienced ones.
  5. Try one of the Suggested Engagement Activities, which can be found under Procedure/Directions in the Lesson Plan section of the activity’s Teaching Tips.

  While students are doing an activity…

  1. Help individual students navigate through the activity.
  2. Provide options for those who finish the activity early:
     • Have them review the activity again to define key vocabulary words.
     • Have them visit related Web links to conduct additional research.
     • Have them completing some type of assessment activity. A number of these can be found under Follow-up Activities/Extensions in the Lesson Plan section of the activity’s Teaching Tips.

  Using the activities without an Internet connection

  1. Order a CD of the activities.
  2. For activity-specific suggestions, consult the Classrooms Without Computers section (in the Lesson Plan section of the activity’s Teaching Tips).
  3. Print the information provided in the Science Background, which might be useful for content reading.
  4. Download the activity in advance from the Amazing Space Web site. Instructions are in the Computer Needs section accessed from the activity’s title page.
  5. Go to the activity’s Grab Bag section and select text, student activities, or other Internet links that direct you to related topics.
