    Two bottles of different-colored water are placed vertically, one on top of the other with open ends together. They remain stable if the bottle with the hotter (red-colored) water is placed on top of the bottle with the…

  • Convection: Transfer of Heat From Earth’s Interior

    Book Chapter |

    In this activity, students conduct experimental trials involving a drop of food coloring moved by convection in a pan of water to observe convection cells. Students record their observations on this model and relate…

  • Modeling Convection

    Journal Article |

    Typically, teachers use simple models that employ differences in temperature and density to help students visualize convection. However, most of these models are incomplete or merely hint at (instead of model)…

  • Convection Connections

    Journal Article |

    Children are fascinated with large bodies of water, such as lakes and oceans. They feel the wind on their faces and observe lake and ocean water as it moves in waves. But do they know what makes the air and water move?…
