Introduction to Physical Science Chemical Reactions

Disciplinary Core Concepts Differentiate between atoms and ions. Identify evidence of a chemical reaction. Learn the importance of water as a medium for some chemical reactions to occur. Cross cutting concepts The initial preview of the base model will suggest that cause and effect relationships may be used to predict both microscopic and macroscopic behavior. The conservation of matter is suggested but not explicitly stated in this first lesson. Modeling and Simulation Learn how computer models can be used to run simulations when dangerous or expensive materials are involved.

Identify aspects of the chemical reaction that are not included in the base model.  Complex Adaptive Systems What features of a complex adaptive system are exhibited in the model of silver nitrate and copper chemical reaction? Disciplinary Core Ideas What is the difference between atoms and ions? What evidence of a chemical reaction was seen in real life an in the computer model? Could the chemical reaction take place without water? Modeling and Simulation Why might we want to simulate chemical reactions on a computer rather than in real life? 

Disciplinary Core Concepts Differentiate between chemical and physical properties of substances. Identify atomic symbols and chemical formulas of the reactions in this module. Identify which reactant is limiting and which is in excess. Identify signs of a chemical reaction and when a chemical reaction stops. Modeling and Simulation The role of parameters and initial conditions are presented and students gain experience with the representation of entities within the model. The setup procedures and other code block are examined.

Automation is observed in this USE phase (student’s using a largely pre-built model). Computer Science Begin to understand the execution order of code and gain exposure to the CS concepts of “looping”, parameters and logic, expressions, variables and functions. Use various debugging and testing methods to ensure program correctness.  Disciplinary Core Ideas What is the difference between the chemical and physical properties of copper?

Describe how many silver nitrate molecules are needed to react with each copper atom? Which reactant is limiting the reaction? Which reactant is in excess in the reaction? How do we know that a chemical reaction has taken place? How do we know when a chemical reaction has stopped? Modeling and Simulation Assessment of whether student was able to implement modifications to the base model. Computer Science Use of CS concepts and constructs such as looping, logic, expressions, conditionals, functions and variables.

Disciplinary Core Concepts Identify the products of a chemical reaction. Identify the factors that stop a chemical reaction. Learn about concepts of limiting reactants and reactants in excess. Learn the importance of balancing chemical equations. Crosscutting concepts Patterns: Macroscopic patterns are related to the nature of microscopic and atomic-level structure.
