Venn Diagram: Comparing Geology and Paleontology

(Instructional Master 7B-1) 15 minutes

• Show students the Venn diagram and explain that, as a class,
  you will use it to compare and contrast the work of a geologist
  and a paleontologist. Remind students that to compare is to tell
  how things are similar and to contrast is to tell how things are
  different.


• Ask students: “How is the work of a geologist and a
  paleontologist the same?” Write student responses where the
  two circles intersect. Possible responses include the following:
  
  
  • Both are scientists.
  
  
  • Both study the history of the earth.
  
  
  
  


• Ask students: “How is the work of a geologist different from the
  work of a paleontologist?” Write responses in the appropriate
  section. Possible responses include the following:
  
  
  • Geologists study non-living things related to the earth, such
    as rocks and what is inside the earth.
  
  
  • Paleontologists use fossils to study plants and animals that
    lived on earth.
