Grade 6 Unit 05: Thermal Energy (10 days)
TEKS
(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
Classwork
- Read 5.4 pp. 200 - 203. Define or describe the highlighted words.
- 1. We have talked about kinetic energy in a previous unit. Explain how kinetic energy relates to thermal energy.
- 2. Look at the thermometer on p. 201. At what temperature are fahrenheit and celsius equal? What is 80oF in Celsius?
- 3. What is absolute zero? How does absolute zero relate to the Kelvin scale?
- 4. Kelvin is a very good scale to use in science, since it has a real zero. What makes Fahrenheit and Celsius more useful for everyday life?
- 5. What is the difference between thermal energy and temperature? Which would have a higher temperature, a hot cup of coffee, or Balmorhea pool?Which would have more thermal energy?
- 6. Heat goes from an object with a ___________ temperature to an object with a _____________ temperature, until the objects have an ____________ temperature.
- 7. Most homes have insulation in the walls and ceiling to slow the transfer of heat. In the winter, is it more accurate to say the insulation keeps the cold out, or keeps the heat in? Explain your answer.
