Lesson Seeds: The lesson seeds are ideas for the indicator/objective that can be used to build a lesson. Lesson seeds are not meant to be all-inclusive, nor are they substitutes for instruction.

Standard 3.0 Life Science

Topic D. Evolution

Indicator 1. Explain that individuals of the same kind differ in their characteristics, and sometimes the differences give individuals an advantage in surviving and reproducing.

Objective d. Examine and compare fossils to one another and to living organisms as evidence that some individuals survive and reproduce.

Activity
Students research a fossil organism and compare it to its modern day descendent. Possible organisms to compare include ferns, cycads, sea stars, reptiles, and mammals. Students prepare labeled images of the organisms to show change over time. Students discuss the possible reasons for the changes in some organisms and the lack of changes in others. Outstanding references for the classroom can be found in the Life Has A History activities at the following URL. http://www.ucmp.berkeley.edu/education/explorations/tours/intro/index.html.
