Integrated Physics and Chemistry Unit 7

Big Idea:

How energy can change forms, transfer from one object to another and radioactive decay.

Student Expectations:

Priority TEKS

I.5D Investigate the law of conservation of energy.

I.5E Investigate & demonstrate the movement of thermal energy through solids, liquids, & gases by convection, conduction, & radiation such as in weather, living, & mechanical systems.

I.5H Analyze energy conversions such as those from radiant, nuclear, & geothermal sources, fossil fuels such as coal, gas, oil, & the movement of water or wind.

I.5I Critique the advantages & disadvantages of various energy sources & their impact on society & the environment.

I.7E Describe types of nuclear reactions such as fission & fusion & their roles in applications such as medicine & energy production.

Student Learning Targets:

I will know that energy is not created or destroyed—it just changes forms.

• I can calculate specific heat.
• I can explain what happens to the heat in a reaction.
• I can show that energy is transformed from one form to another and it is not created or destroyed in a reaction.

I will use lab equipment to show conduction, convection, and radiation.

• I can use specific heat to determine the heat transferred in a physical or chemical change.
• I can use heat of fusion or heat of vaporization to find the heat absorbed or released during a phase change.
• I can illustrate conduction using solids or liquids in lab.
• I can show convection processes using liquids or gases in lab.
• I can demonstrate radiation of heat using solids or liquids.
• I can identify heating processes and how they affect weather or mechanical systems.
• I can use cooling processes to illustrate changes in mechanical or weather systems.

I will identify the energy transformations involved in heating processes.

• I can show that energy conversions are used to produce electricity.
• I can compare energy production processes to determine the more efficient process.

I will determine the advantages & disadvantages of various energy sources.

• I can assess the advantages & disadvantages of energy sources such as coal, oil, geothermal, wind, & solar.
• I can determine the environmental impact of energy sources such as coal, oil, geothermal, wind, & solar.

I will know how fission and fusion can be used for medicines and energy.

• I know the difference between fission and fusion.
