TEKS Objectives:

9)  Force, motion, and energy. The student knows that the Law of Conservation of Energy states that energy can neither be created nor destroyed, it just changes form. The student is expected to:

(A)  investigate methods of thermal energy transfer, including conduction, convection, and radiation;

(B)  verify through investigations that thermal energy moves in a predictable pattern from warmer to cooler until all the substances attain the same temperature such as an ice cube melting; and

(C)  demonstrate energy transformations such as energy in a flashlight battery changes from chemical energy to electrical energy to light energy.

Jan. 2-3, 2012 Discuss types of energy transfer: conduction, convection, and radiation and give examples of each.  Lab activity on conduction of heat.

Jan. 4-5, 2012 Continue to discuss energy transfer and the direction of thermal movement from warmer to cooler areas.  Lab activity on convection.

Jan. 6-9, 2012 Continue to discuss energy transfer including energy transfer through space.  Lab activity on heat radiation.

Jan. 10-11, 2012 Discuss energy transformations from one type to another. Review energy transformations in an electrical power plant.  Lab activity demonstrating energy transformation in common situations.

Jan. 12-18, 2012 Study Sheets and review over energy transfer and transformations.  Study Sheets will be due Jan. 17 and 18.

Jan. 19-20, 2011 Test over energy transfer and transformations.  Review all study sheets carefully.  Extra points will be given to students who get their study sheets signed.
