STANDARDS:
HS-PS3-1: Create a computational model to calculate the change in the energy of one component in a system when the change in energy o the other component(s) and energy flows in and out of the system are known.
HS-PS3-2: Develop and use models to illustrate that energy at the macroscopic scale can be accounted for as a combination of energy associated with the motions of particles (objects) and energy associated with the relative position of particles (objects).
HS-PS3-4: Plan and conduct an investigation to provide evidence that the transfer of thermal energy when two components of different temperature are combined within a closed system results in a more uniform energy distribution among the components in the system.
OBJECTIVES:
_ Students will be able to recognize common errors while writing CER and apply it to correct their own work.
_ Students will be able to calculate the bond enthalpy of given molecules.
_ Students will be able to calculate the change in enthalpy of given chemical reactions and determine whether the reaction is endothermic or exothermic.
THREE DIMENSIONAL FOCUSES:
Science and Engineering Practice:
_ Developing and Using Models: Develop and use a model based on evidence to illustrate the relationship between systems or between component of a system
Disciplinary Core Ideas:
_ PS3. B.2: Conservation of energy means that the total change of energy in any system is always equal to the total energy transferred into or out of the system.
_ PS3. B. 3: Energy cannot be created or destroyed, but it can be transported from one place to another and transferred between system.
Crosscutting Concept: Energy and Matter
_ Energy cannot be created or destroyed – only moves between one place and another place, between objects and/or fields, or between systems.
_ Systems and Systems Models: When investigating or describing a system, the boundaries and initial conditions of the system need to be defined and their inputs and outputs analyzed and described using models.
