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 calculate the total amount of heat substances need to change its temperature with the incorporation of energy required for phase change.
_ Students will be able to set up and calculate different quantities involved in a transfer of thermal energy between two objects within a closed system and make the connection to the Law of Conservation of Energy.
_ Students will be able to apply the principle of calorimetry into solving basic energy transfer applications.
THREE DIMENSIONAL FOCUSES:
Science and Engineering Practice: Develop and use model based on evidence to illustrate the relationships between systems or between components of a system.
Disciplinary Core Ideas: Conservation of energy means that the total change o energy in any system is always equal to the total energy transferred into or out of the system
Crosscutting Concept: Energy cannot be created or destroyed – only moves between one place and another place, between objects and/or fields, or between systems.

PART 1: MORE CALORIMETRY REVIEW AND PHASE CHANGE CALCULATION
_ For this week Monday and Tuesday, we will continue with more practice on calorimetry as well as incorporating some phase change calculation problems.
For those who still don't understand the concept, please watch the following videos:
_ Phase Change Calculation: https://www.youtube.com/watch?v=AhKRUA4_viY
_ Calorimetry: https://www.youtube.com/watch?v=BGcDUybbTW0
Note: The second video also consists of some phase change calculation as well not not as detailed as the first one.
For Monday zoom meeting, I will redo a phase change calculation with you
Example: Calculate the total amount of energy (in Joules or Kilo-joules) to bring 200 grams of ice at - 25 degree Celsius to 150 degree Celsius.
For the rest of the time, I will be answering questions regarding the topic of calorimetry.
ASSIGNMENT: Complete the worksheet below and submit it to Google Classroom by 9:00 PM on Tuesday April 28th.
