Journal Entry:

What is something you are really good at? How did you get good?

Learning Intentions

• We will learn what temperature is a measure of, what the different units are that are used in science to measure temperature and what they are each based off.

• We will learn how to make predictions about the results of a transfer of thermal energy between systems at the particle level.

• We will learn how to apply the conservation of energy to relate the magnitudes of energy changes occurring in two or more interacting systems, including identification of the systems, the type (heat vs work) or the direction of the energy flow.

Closing Task:

You can apply law of conservation of energy  to answer questions about energy in a system.

Content Standards being covered:

Energy is transferred between systems either through heat transfer or through one system doing work on the other system. (EK 5.B.1)

Temperature is a measure of the average kinetic energy of atoms and molecules. (EK 5.A.1)

The process of kinetic energy transfer at the particulate scale is referred to in this course as heat transfer, and the spontaneous direction of the transfer is always from a hot to a cold body. (EK 5.A.2)

When two systems are in contact with each other and are otherwise isolated, the energy that comes out of one system is equal to the energy that does into the other system. The combined energy of the two systems remains fixed. Energy transfer can occur through either heat exchange or work. (EK 5.B.2)
