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.
