Activity Title   A Systems Model To Show The Limiting Reactant

 

Subject Area/Concept:  Chemistry,  Physical Science   

 

Grade Level:  Jr and Sr High School

 

 

Tool:          o  Image Processing                o GIS          o  Mol. Visualization                X   Stella

 

 

Objective(s):  Use technology to model a chemical system.

 

 

Data Source: none required

 

 

 

Procedure:  Design the stores, flows and converters required to show a student selected reaction.  Use various inputs of the reactants and show the resulting amounts of products.

 

 

 

Student Inquiry Questions:   What are the relationships of the reactants to products of a chemical reaction?  Can a model be build to show this relationship?

 

 

 

 

 

 

 

Notes to Instructor:  While the reaction is not a linear one over time the beginning and ending points are the same.  The fact of the non-linear nature of most reactions can be used later to explore kinetics and then the model can be modified to show reactant use over time.
