Journal Entry:

Put a pot of water on the stove. Before long, you cannot touch the metal pot, but you can still put your finger comfortably into the water. Propose at least two different hypotheses to explain why.

Learning Intentions

• We will learn the definition for specific heat capacity.
• We will learn how to complete simple specific heat capacity calculations.

Closing Task:

You can determine the calories of heat needed to heat a substance to a specific temperature.
 

Content Standards being covered in this unit:

Student can identify types of energy and explain energy changes.

Students can create a computational model to calculate the change in the energy of one component in a system when the change in energy of the other component(s) and energy flows in and out of the system are known (HS-PS3-1 and CCC Energy and Matter)

Students can develop a model to illustrate that the release or absorption of energy from a chemical reaction system depends upon the changes in total bond energy.(HS-PS1-4 and CCC Energy and Matter) .

Students can 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-PS3-2 and CCC Energy and Matter)

Students can 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 (second law of thermodynamics) (HS-PS3-4 and CCC Energy and Matter)
