  • Colligative Properties, Boiling Point Elevation, Freezing Point Depression, Concentration, Solute & Solvent, Boiling Point, Freezing Point, Phase Changes, Molecular Motion, Graphing, Physical Properties, Heat, Temperature | High School

    Simulation: Colligative Properties

    In this simulation, students will investigate the effects of different solutes, and different amounts of those solutes, on the boiling point and freezing point of a solution. Students will see particle-level animations of boiling and freezing with different types and amounts of solutes, as well as graphical representations of the results of each trial.

  • Colligative Properties, Boiling Point Elevation, Freezing Point Depression, Concentration, Solute & Solvent, Boiling Point, Freezing Point, Phase Changes, Molecular Motion, Graphing, Physical Properties, Heat, Temperature | High School, Middle School

    Access is an AACT member benefit. Activity: Simulation Activity: The Effect of Solutes on Boiling and Freezing Point

    In this activity, students will use a colligative properties simulation to investigate the effects of different solutes, and different amounts of those solutes, on the boiling point and freezing point of a solution. Students will see particle-level animations of boiling and freezing with different types and amounts of solutes, as well as graphical representations of the results of each trial.

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

    Access is an AACT member benefit. 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, Mixtures | 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 | Middle School, High School

    Access is an AACT member benefit. 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, Temperature, Physical Change | Middle School

    Access is an AACT member benefit. 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.

    Access is an AACT member benefit. Activity: Simulation Activity: Heating Curve of Water

    In this simulation, students will investigate qualitatively and quantitatively what happens as water changes states.

  • Physical Change, Intermolecular Forces, Heating Curve, Phase Changes, Graphing, Heat, Exothermic & Endothermic, Temperature, Freezing Point, Melting Point | High School

    Access is an AACT member benefit. Lab: Heating & Cooling Curve

    In this lab, students will create a phase change graph by adding and removing heat to observe and record data during actual phase changes.

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

    Access is an AACT member benefit. 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.

    Access is an AACT member benefit. Lesson Plan: Fuel Line Antifreeze

    In this lesson students will explore the role of a gasoline additive, fuel line antifreeze (generally methanol or 2‑propanol), in reducing the potential of water to block fuel lines in freezing weather. Students will prepare test tube models of water-contaminated fuel tanks and explore the effect of adding different types of fuel line antifreeze. This lesson can be used to bolster concepts about miscibility, density, intermolecular forces, phase changes (freezing), and colligative properties (freezing point depression).

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

    Access is an AACT member benefit. Lesson Plan: Salting Roads in Winter

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