In this activity, students travel back in time as explorers to collect scientific information on plant and animal life during various geological eras. The author uses the book, The Deep Time Diaries as way to bring literature into the science classroom and to introduce field journals. Students have two days to collect research from the internet, books, and maps to complete their field-journal entries. They then compile the information and create drawings of what they discovered. To add a creative element to the field journals, students also invent an imaginary story line of what could have happened during their jump back in time.
