Objectives of Energy

Essential Question: Do you believe that? (theory explains observations)
Enduring Understanding: In = Out for Mass and Energy

The student should be able to:(bolded number are MA Framework Standard numbers)
Show all work in mathematical problems as stated in class.

Energy
1. Understand and give example of the Law of Conservation of Energy including giving example of kinetic and potential energies.[10.1](6.4)
2. Understand and be able to explain the 2nd and 3rd Law of Thermodynamics.

Recognize that there is a natural tendency for systems to move in a direction of disorder or randomness (entropy). Part 3rd Law of Thermodynamics

3. Explain the difference between heat and temperature.[6.2]
4. Memorize my definition of temperature and explain the difference between an absolute and relative temperature scale.
5. Explain the Kinetic Molecular Theory and how it applies to temperature and 2nd Law of Thermodynamics.[1.1], [1.3](1.3)
6. Using information from EndoExothermicReactionLab, explain the difference between an exothermic and endothermic reactions including activation energy and the difference between the PE_R and PE_P.[10.3](6.4)

For 2010-2011, Math Section
1. Show all work in mathematical problems as stated in class.
2. Use scientific notation in calculations.
3. Use dimensional analysis appropriate to solve problems including showing all work; units canceling, number before you round in correct scientific notation and two more sig fig than in answer, and answer in proper form (sig fig & scientific notation if needed).

Mass
1. Calculate denisty problems and understand which substance float on another due to density.
2. Understand the difference between the density of the different phases (state) of matter, how temperature affects density of substance (in phase), and density between solutions (e.g. saltwater) and solvent (e.g. freshwater).

Not for 2010-2011, Energy
1. Explain the three different modes of heat flowing including examples from your house.
