Journal Entry:
1. Imagine that you are sitting near a campfire. You feel
warm. Explain how you think the warmth gets from the burning wood to your
body.2. The fire goes out. The next morning, you
find ashes that are the same temperature as the air. Explain why the ashes
are no longer hot.
Learning Intentions
- We will learn how to explain situations involving energy
transfer.
- We will learn how to define thermal equilibrium.
- We will learn the first and second law of thermodynamics
Closing Task:
You can
state the first and second law of thermodynamics.
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)
