Develop a Model to Represent the Natural World
The student is expected to represent the natural world using models such as rivers, stream tables, or fossils and identify their limitations, including accuracy and size.
The student uses critical thinking and scientific problem solving to make informed decisions.
A Closer Look, Scientific Models: Annenberg Learner (website) - Important information about scientific models, what they are, how they are developed, how and why they change over time, and what their limitations are.
Models are the Building Blocks of Science: The University of Texas (website) - Online article discusses different types of models, and explains their purpose and importance in the scientific world and other disciplines.
Erosion and Deposition: NASA/Goddard Space Flight Center Education Programs (website) - Students will: 1) observe and identify agents of erosion and deposition by examining the features formed and the processes that influenced their formation; and 2) represent the natural world by constructing detailed models that illustrate human impact on the environment.

Elaboration Lessons and Extensions
Make a Model Fossil: Minnesota Science Teachers Education Project (website) - Students model the process of fossilization by creating molds and/or casts from natural objects found locally.
Have students bring recycling materials from home and use the materials to build a model water system or a fossil.
