An earth science video starts with a basic explanation of convection currents and then how they occur in the molten rock of the mantle causing the lithosphere to travel with it.
Learners explore convection. For this lesson on heat and energy, students investigate how heat moves in convection currents. They use their finding to better understand how convection currents effect the movement of tectonic plates.
Young scholars explain the role of convection currents in the movement of air. In this earth science lesson, students investigate convection by observing a boiling water in the lab. They describe how fluids move when they experience convection.
Students draw a line graph, and use graphing as a tool to discover more about conduction, convection and radiation. They should design their own experiment using heat sensitive paper to show they explain these 3 processes.
Sixth graders work together to show convection currents in the air. They construct a paper propeller that be caused to spin due to the transfer of heat energy through the air.
Students use water, beakers, hot plates, paper dots, and goggles to participate in a hands on activity where they see how a convection current creates wind. For this convection current lesson plan, students participate in a hands on activity to see how the hot water molecules move substances.
Students explore weather by completing a worksheet in class. In this geology lesson, students discuss the traveling of heat through convection currents and complete a model activity using a beaker, water and hot plate. Students complete an Earth science worksheet and define vocabulary terms.
Sixth graders use jars of water, parsley and heating plates to observe convection currents. They discuss the demonstration and consider how their observations might apply to architecture and building design.

New Review Give and Take

Heat-sensitive liquid crystal sheets are available in a variety of sizes and temperature ranges. Purchase a class set of hand-held sheets and color half of each with a silver permanent marking pen. Learners of light can hold them under a lamp and see that light is converted into thermal energy and that there is no change under the silver half since light is reflected away. 
Students watch a demonstration using a plastic bag and a hair dryer to create a hot air balloon. After the demonstration, they discuss the results and whether or not hot water behaves the in the same manner as hot air. They conduct their own experiments using soapy water in a pie pan and heating it with a candle. After observations are recorded, they compare the experiments and discuss how this relates to what is going on in the mantle of the Earth.
Discuss the difference between conduction, convection and radiation of thermal energy, and complete activities with your class by investigating the difference between temperature, thermal energy and the heat capacity of different materials.
In this thermodynamics worksheet, students learn about insulators and conductors. Students compare the three ways thermal energy is transferred: conduction, convection, and radiation. This worksheet has 22 matching, 1 multiple choice, 3 fill in the blank, and 4 short answer questions.
Somebody in the Nevada Joint Union High School District has a talent for focusing the important, organizational skills, and a creative eye for creating sharp science presentations! Here is one on heat transfer.  Conduction, convection, and radiation are explained at the level of high school physicists, but in such an orderly and cohesive manner that viewers feel no heat! By the end of the slide show, learners are able to explain the three types of transfer, calculate transfer rates, and relate radiation to temperature.
Students explain the density of water as it relates to temperature. They describe the dynamics of ocean currents as they relate to temperature and density. They identify the forces governing convection in liquids.
Students investigate the physics of heating and cooling through conduction, convection, and radiation. Working in groups, they determine the best way to cool a can of water and warm a can of water. Temperature is taken at five minute intervals and they may use items provided to either cool the water or warm the water. Groups explain their heating and cooling devices to the class and report how successful the devices were.
In this thermodynamics worksheet, students read about conduction, convection and radiation. They answer 47 questions about heat transfer, thermal equilibrium, insulators, conductors and the states of matter.
High schoolers construct their own lava lamp using simple substances. In this physics instructional activity, students explain how difference in density causes convection. They solve for forces and buoyancy using mathematical equations.
Students work on problems in which they investigate conduction, convection, and radiation. They attempt to maintain the warmth in one can of soda while cooling the other as much as possible in a thirty minute period. They examine how engineers apply similar principles.
Students experiment to produce a visual convection current in the classroom and compare it to the images taken of convection cells in the Sun. They analyze the source of the Sun's energy and this type of energy transport.
Fire up your physics class by assigning a worksheet on heat transfer. They explain in words the differences among conduction, convection, and radiation. They reveal their knowledge of transfer rates, convection currents, and electromagnetic waves. If you can locate the PowerPoint presentation on thermal physics that was also posted by the Nevada Joint Union High School District, you will find that this assignment follows it to a tee. It can be used as a note-taking guide or homework assignment.
