These classroom activities are in PDF format. You will need Adobe Acrobat Reader to view them. To use the vocabulary links, you will need the glossary, and the addendum glossary. The following activities were provided by various educational organizations and educators for inclusion on the Visit to an Ocean Planet CD-ROM. We thank all involved for their efforts in providing high-quality activities. Please see the CD-ROM for individual credits.
