Thermal Energy Unit 2012

Day One--Heat vs. Temperature
 * Introduce Exit Slip question, "What is the difference between heat and temperature? Give an example." (2)
 * BrainPop: Temperature (and Review Quiz) (7)
 * BrainPop: Heat (and Review Quiz) (7)
 * Thermometer activity--hold with thumb/finger 1 min. and notice the change; create a bottle thermometer with colored water and observe the change throughout the day. Have several students (molecules) demonstrate what happens as particles of matter (in thermometers and other matter) heat up, vibrate more, and expand. (10)
 * Heat activity (START RIGHT AWAY AND CONTINUE DURING OTHER ACTIVITIES)--heat a small pan of water and a medium pan of water on two cooktops to see which one will boil first (small one); Discuss how "heat" doesn't necessarily mean "hot". Boiling pan of water vs. boiling pool of water (same temperature, but more heat in pool). Boiling pan of water vs. iceberg (different temperatures, but more heat in iceberg!). Fill a large bottle and a small soda bottle with water for a heat vs. temperature display in the room. (10)
 * Students complete Exit Slips and turn in. (5)
 * Discuss pretest questions that connect to instruction (1, 2, 3) (10)
 * Discuss pretest questions that connect to instruction (1, 2, 3) (10)

Day Two--Conduction
 * Thermometer follow-up (1)
 * Return Exit Slips and discuss (5)
 * Introduce today's Exit Slip question, "What is conduction? What is the difference between conductors and insulators of thermal energy? Give examples." (2)
 * Introduce the idea that heat can travel in three ways: conduction, convection, and radiation. (1)
 * Read ScienceSaurus pp. 288-294. Discuss the conduction paragraph together. (15)
 * Conduction, Spoons, and Dominoes activity; "Rapid-pinch" of a metal spoon and a plastic spoon taken out of boiling water. (15)
 * Students complete Exit Slips and turn in. (5)

Day Three--Convection with Liquids
 * Return Exit Slips and discuss (5)
 * Introduce today's Exit Slip question, "What is convection? Give examples for liquid and gas convection." (2)
 * Read ScienceSaurus p. 294 again; discuss the convection paragraph together. (5)
 * Hot and Cold water convection activity with student-made student page. (30) //Note: Do not dissemble the bottles after the last class; keep for next-day discussion.//
 * Homework--Online games.

Day Four--Convection with Gases
 * Pass out hot/cold bottle systems and discuss the change after 24 hours (colors and temperatures the same) (5)
 * Draw pictures with paragraphs together to illustrate what happened with the hot/cold water bottle convection. (20)
 * Begin Magic Spiral investigation/competition (20)
 * Homework--Online games.

Day Five--Finish Convection and Radiation
 * Remind students of the Exit slip question (1)
 * Magic spiral investigation/competition (25)
 * Complete Exit Slip (5)
 * Students complete printtestTHERMAL2011 as a review of key information (15)
 * Homework--Online games.

Day Six--Radiation and Review
 * Discuss printtestTHERMAL2011 (15)
 * Introduce Radiation. Discuss how it is the same/different from conduction and convection. (5)
 * Radiation vs. Conduction--Who Will Win? Heat 100 ml of water in a beaker for one min. and check temp. change. Repeat with a second beaker for one min. in a microwave. (5)
 * Discuss other examples of radiation--the sun, x-rays for cavities/broken bones. (1)
 * Online games review with iPads (20)
 * Homework--Online games.

Day Seven--Test
 * Students complete assessment (20)
 * Other (25)
