Type: Lesson/Unit Plan

Overview:

This lesson is the first of a two-part series on fossils. In the first part of this lesson, students will discuss what they know about horses. They will then do the same for a Stegosaurus. This comparison is subtle but demonstrates what they know as fact and what they know as theory, and more importantly, what sort of proof scientists need for facts to exist. As students discuss the Stegosaurus, they will realize that fossils tell a story about the animal. They describe facts, i.e. how tall, how wide, what kind of teeth, and they describe ideas, i.e. what the dino may have eaten, how fast it may have moved due to its leg structure, and how it may have hunted. Once students have an understanding of how to extrapolate facts and ideas from fossils, they will do some of their own digging in the second part of this lesson to practice using the thinking skills they've obtained.

Content Standard(s):
Science
SC2015 (2015)
Grade: 3
9 ) Analyze and interpret data from fossils (e.g., type, size, distribution) to provide evidence of organisms and the environments in which they lived long ago (e.g., marine fossils on dry land, tropical plant fossils in arctic areas, fossils of extinct organisms in any environment).

Scientific And Engineering Practices:
Analyzing and Interpreting Data
Crosscutting Concepts: Scale, Proportion, and Quantity
Disciplinary Core Idea: Unity and Diversity
Evidence Of Student Attainment:
Students:
  • Analyze data from fossils to provide evidence of organisms and the environments in which they lived long ago.
  • Interpret data from fossils to provide evidence of organisms and the environments in which they lived long ago.
  • Provide evidence of organisms and the environments in which they lived long ago.
Teacher Vocabulary:
  • Analyze
  • Interpret
  • Data
  • Fossils
  • Type (mold fossils, cast fossils, trace fossils, true form fossils)
  • Size
  • Distribution
  • Evidence
  • Organisms
  • Environment
  • Extinct
  • Relationships
Knowledge:
Students know:
  • That fossils represent plants and animals that lived long ago.
  • The relationships between the fossils of organisms and the environments in which they lived.
  • The relationships between types of fossils and the current environments where similar organisms are found.
  • That some fossil represent organisms that lived long ago and have no modern counterparts.
  • The relationships between fossils of organisms that lived long ago and their modern counterparts.
  • The relationships between existing animals and the environments in which they currently live.
Skills:
Students are able to:
  • Organize data about fossils of animals and plants.
  • Identify and describe relationships in the data to make sense of fossils.
  • Interpret data to make sense of fossils.
  • Provide evidence based on data from fossils.
Understanding:
Students understand that:
  • Fossils provide evidence of organisms that lived long ago.
  • Features of fossils provide evidence of organisms that lived long ago and of what types of environments those organisms must have lived in.
  • Science assumes consistent patterns in natural systems (based on relationships found in the data).
  • Environments can look very different now than they did a long time ago.

NAEP Framework
NAEP Statement::
E8.3: Fossils provide important evidence of how life and environmental conditions have changed in a given location.

NAEP Statement::
E8.4: Earth processes seen today, such as erosion and mountain building, make it possible to measure geologic time through methods such as observing rock sequences and using fossils to correlate the sequences at various locations.



Alabama Alternate Achievement Standards
AAS Standard:
SCI.AAS.3.9- Match a fossil to the organism from which it was formed.
