Investigating Convection Currents

Pupils study tectonic plates by using the concept of convection.  In this investigative lesson students observe a demonstration then make their own convection current. 

Compare the density of different salt solutions and then observe currents that are caused by the difference. Set up a demonstration of dynamic equilibrium. The intent with these activities is to begin building understanding of density...

Students listen as the teacher explains convection currents in the ocean. They experiment with finding a smoking match in the classroom with their eyes closed. Students discuss what might effect their ability to pinpoint the smoke...

Review heat transfer with your seventh graders and guide them in making a practical application. Learners use a paper cutout spiral to locate convection currents in the classroom and throughout the school. They record the temperature at...

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. In this convection current lesson plan, students participate in a hands on...

Students 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 introduced to the interior structure of the Earth. They explore how the Earth's interior is broken down according to both it's physical properties and it's chemical composition. Students explore how convection currents within...

Students analyze how engineers study temperature inversions and convection currents to understand why pollution levels may be higher in some areas than others. They participate in an experiment that allows them to build simple models to...

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.

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.
