Do not close this window!
Closing this window or going to a different page in this window will, on most computers, cause the LeafLab applet to close with no warning.
The LeafLab applet will open up in a separate window. You can resize the applet window if you wish. Before the applet shows up it must download several data files and images, so please be patient for a few minutes if it appears that nothing is happening.
What should I do if the applet fails to load?
If this is your first attempt to access this applet, you may not have a Java-enabled browser. Check the Technical Requirements for the lab to make sure that your browser is correctly configured for this applet.
If you have run the applet before, but it fails to reload, your browser has probably run into java memory overload. Quit your browser and restart it.
