Demonstrators should be read from bottom to top, but need not be demonstrated sequentially.

 

Elementary Demonstrators

 

•  Investigate models that represent objects, events, or systems.
•  Investigate models to determine how things work.
•  Represent a real event, object, or concept with a model.
•  Use models to depict the function of an object, event, or system.
•  Investigate the significance of perspective.
•  Evaluate appropriateness of components and scale to a real object being modeled.

             

Middle School Demonstrators

 

•  Formulate multiple perspectives through the use of a model.
•  Evaluate the functions, behaviors, and limitations implied by a model.
•  Investigate properties that change or remain constant with changes in scale.

             

High School Demonstrators

 

•  Use a model to analyze or predict behavior of objects, materials, or living things.
•  Evaluate the appropriateness of the scale of a model and its effects on the model's behavior.
•  Identify assumptions underlying a model and evaluate their effects on the appropriateness of the model.
•  Represent an idea, structure, or system with various types of models (e.g., physical, conceptual, mathematical).

 

 

Sample Teaching/Assessment Strategies

 

Collaborative Process: Cooperative Learning / Community-Based Instruction: Field Studies / Continuous Progress Assessment: Conferencing, Self-assessment \ Graphic Organizers: Advance Organizers, KWL / Problem Solving: Heuristics, Case Studies, Debate / Technology/Tools: Distance Learning, Telecommunications / Whole Language Approach / Writing Process

 

These sample strategies offer ideas and are not meant to limit teacher resourcefulness. More strategies are found in the resource section.

 

Ideas for Incorporating Community Resources

 

•  Visit a planetarium to study available models of the universe.

•  Locate local rocketry and/or airplane hobbyists who will demonstrate their models and explain how the different parts work together.

•  Explore the use of topographical maps by different agencies in the community (e.g., phone company, gas company, soil conservation, municipalities, agricultural extension agency).

 

Core Concept - Models and Scale

 

Sample Elementary Activities

•  Diagram the energy flow of a food web from the energy source to the final consumer. Include at least one producer, two consumers, and one decomposer in your diagram. PE, OE
•  Find alternate routers to a specific location (e.g., home, cafeteria, playground). Draw a map to scale showing at least one route. PE, OE
•  Construct a model of a building. Compare the model to a real structure. Identify the limitations and advantages of the model. P
