In this activity, students will be introduced to the base chemical reaction model of silver nitrate reacting with copper that is provided in this module.

• Watch the video introduction to the chemical reaction base model
• Run the base model and make observations
  
• Reflect on abstractions made in the model 
• Check your understanding
  

Watch the introduction to the Chemical Reaction base model 

Run the base model and make observations

Using the Model Observation form examine the base model, www.slnova.org/GUTS/projects/9879, to determine the agents, their behaviors and interactions between agents. Record your observations on the Model Observation form.

Reflect on the abstractions made in the model

In a balanced chemical equation format:

2 AgNO₃ (aq) + Cu (s) ---> Cu(NO₃)₂ (aq) + 2 Ag (s)

In the model, which atoms and compounds are represented? Also, how do the atoms and compounds move?

Quiz questions:



Reflection:
Reflect on the relationship between the model of the chemical reaction and the real-world demonstration.  What parts of the real-world demonstration were captured in the model?  What are some differences?  Post your reflections in your portfolio in the section "Reflections->Computer Modeling and Simulation" under the heading "Chemical reaction demo".
