    Lab: Sweet, Salty and Cold as Ice

    In this lab, students conduct a micro-scale investigation to explore how various solutes affect the freezing point of water. Because of the small volume of liquid used, results are visible within minutes. Students observe what happens to the liquids as they are cooled and use their observations to infer what is going on at the particle level. They will use the results to explain the familiar phenomena of why we salt our roads and sidewalks in the winter and why freshwater lakes and ponds freeze over more easily than saltwater oceans in the winter.

    Lab: How does Salt "Melt" Ice?

    In this lab, students will consider why salt is used to aide in snow clearing and to help keep icy roads safe. They will investigate how salt ‘melts’ ice and determine the best type of salt to do so. Additionally, students will explore the advantages and disadvantages of the various different types of salt.

  • Freezing Point, Phase Changes, Freezing Point Depression | Middle School, High School

    Lab: Freezing Ice Cream

    In this lab, students will investigate changing states of matter, chemical reactions, and the properties of ice and salt while creating their own ice cream.
