Be sure Squeak is installed successfully on your computer. It may take about 45 seconds for the project to load for a fast connection (up to 15 minutes for a slow modem connection). Wait until you see an orange flap at the lower left labeled Navigation. Click the flap to open and close it and access some neat tools. If you click Escape Browser, you will have more space. Click Browser Reentry to get back your Browser controls.
Norbania: Norbert and Zot are from Norbania (astronomers call this an extrasolar system). Norbania has planets like our solar system orbiting around a far away star or sun, but the planets are very exotic. It would take Norbert and Zot too long to return to Norbania so they need your help to make a model of (or simulate) Norbania so they don't feel homesick.
Plotting Tool: There are several challenges in this project. You may want to review plotting data before you do Challenge 2. If you are already in the extrasolar activity, click Browser Reentry and then click the browser back button to return to this page. Click the PLOTTING button at the left to review plotting.
Challenge 4: First watch the recording of how to use Squeak to make the objects on the page perform for you. Playing is a great way to learn. You must click Escape Browser and your resolution must be set at 1024x768 to view the recording properly. Click the PLAYING button at the left to start the recording. Then return to NORBANIA and challenge yourself to add a fourth planet. Submit your Squeak projects for challenges 3, 4, and/or 5 to the NASA CONNECT web site. We will post all the good entries that we receive to acknowledge your good work and let others learn from your solution.

After you are familiar with the Squeak Extrasolar project, try these additional challenges. Explore, create, and have fun learning.
