Be sure Squeak is installed successfully on your computer. It may take about 15 seconds for the project to load for a fast connection (up to 5 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.
Norbesaur: Our ficticious Norbesaur was a theropod that was capable of running and walking. How do scientists know dinosaurs could run when they weren’t there? They study dinosaur tracks. You can make measurements on a fictitious Norbasaur and his cousins to show that there is a relation between their stride lengths and how fast they are moving. You will also see how your walking and running stacks up with Norbesaur and his cousins. Click on the NORBESAUR button to start.
Tracks: After plotting and analyzing your data you will be able to determine how fast one of Norbesaur’s other fictitious cousins was moving. Click on the TRACKS button to start.
Plotting Review: You will need to plot data to complete Challenges 2 and 3 of this project. You may want to review plotting data before you start. If you are already in the Norbesaur 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 800x600 to view the recording properly. Click the PLAYING button at the left to start the recording. Then return to NORBESAUR and challenge yourself to create a SaberZot. See details in the book on the NORBESAUR activity or in the additional challenges link below. Submit your Squeak projects for the Challenge 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 Norbesaur project, try these additional challenges. Explore, create, and have fun learning.
