For this history of life worksheet, students review 4 vocabulary words associated with the beginnings of life. Students place these terms into a crossword puzzle and then complete 2 fill in the blank questions.

In this science learning exercise, students look for the words that are related to the concept of zoology that is reviewed in the sheet. They also acquire new vocabulary.

Berkley offers an introduction to archaebacteria--ancient bacteria--including the history of the topic, scientific findings, and where to find archaeans. Includes images and links.
