Unit 10: Thermal Energy
Estimated Date Range: March 20 – March 31
Estimated Time Frame: 10 days
In this unit, students will determine if examples demonstrate conduction, convection, or radiation. Students will understand that
liquids and gases primarily transfer energy by convection and explain that solids do not transfer energy by convection, because of
the structure of the solid. IPC students should identify a substance as a conductor or insulator. Students will relate the
conduction/insulation property of a substance to its specific heat, and the color of a substance to its ability to absorb infrared
radiation. In grade 6
th
, students demonstrate that new substances are made when 2 or more substances are chemically
combined; in 7
th
grade, students examine everyday chemical phenomena, like rusting and tarnishing. Eighth grade students learn
to recognize balanced chemical equations but are not expected to balance equations by adding coefficients.
At home connections:
•
Students can create images that will help them remember and explain the meanings of each type of thermal energy
(conduction, convection, and radiation). After creating the images, students can identify, label, and explain objects that
act as insulators and conductors.

se a world map to show the locations of major rainforests and deserts
o Show how convection currents form around the Earth's equator
• Create a scenario to describe the movement of thermal energy in systems
such as weather, insulated rooms, heating systems, combustion engines,
refrigerators, and air conditioners
Estimated Date Range: April 3 – April 18
Estimated Time Frame: 10 days
In this unit, students will understand the Law of Conservation of Energy. Students will differentiate between open and closed
systems. Students will define energy transformation and give examples of the types of transformation or conversion processes
necessary for different energy sources to produce electricity such as the processes involved in the operation of a hair
dryer. Students will know that energy transformation or conversion takes place in heat engines. IPC students will evaluate
the efficiency of different transformation processes such as those that produce electricity from radiant, nuclear, and geothermal
sources as well as moving water, wind, and fossil fuels, and relate the advantages and disadvantages of several energy sources.
At home connections:
• Students can search the internet to find pictures to identify areas around the world where geothermal energy is used.
Students should explain why that form of energy is used in that area of the world.
