1 – 8 of 8 Classroom Resources

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

    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.

  • Mixtures, Freezing Point, Phase Changes | Elementary School

    Lab: Coffee Creamer Ice Cream

    In this lab, students will investigate how dissolving salt (sodium chloride) in water changes the freezing point of the solution. While investigating this, they will make ice cream from small coffee creamer cups.

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

  • Freezing Point, Phase Changes, Physical Change, Temperature | Middle School

    Lab: Lemon Ice

    This activity explores the interaction between salt and water (ice) as a way to further investigate their impact on the state of matter of a substance. Students will use salt and ice to create a slushy lemonade drink without the use of a freezer. They will learn through this hands-on experiment how salt and ice can rapidly cool a liquid.

  • Melting Point, Freezing Point, Phase Changes, Physical Change, Acids & Bases | Middle School

    Lesson Plan: Stearic Acid

    In this lesson, students investigate how stearic acid undergoes a phase change from solid to liquid and back from liquid to solid. Temperature readings will be collected at one-minute intervals once the acid melts, the heat escapes, and the acid cools. Students are introduced to the idea that energy loss does not always result in a continuous temperature drop.

  • Physical Properties, Solubility, Freezing Point, Phase Changes, Physical Change, Solute & Solvent, Freezing Point Depression, Freezing Point | Elementary School

    Lesson Plan: Salting Roads in Winter

    In this lesson, students investigate how the freezing point of water changes when salt is added.

  • Freezing Point, Physical Change, Temperature, Exothermic & Endothermic, Boiling Point | Middle School, High School

    Demonstration: Energy

    In this demonstration, students will observe the exothermic and endothermic properties of state changes of substances with different freezing and boiling points.

  • Density, Physical Properties, Melting Point, Freezing Point, Phase Changes, Physical Change, Molecular Motion, Freezing | Elementary School

    Lesson Plan: Pothole Science

    In this lesson, students investigate how the density and therefore the volume, of water changes when it freezes.
