• 

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

  Activity: Simulation Activity: The Effect of Solutes on Boiling and Freezing Point Mark as Favorite (29 Favorites)

  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

  Lab: How does Salt "Melt" Ice? Mark as Favorite (50 Favorites)

  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 Mark as Favorite (42 Favorites)

  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.

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

  Demonstration: Energy Mark as Favorite (9 Favorites)

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

• 

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

  Lab: Lemon Ice Mark as Favorite (7 Favorites)

  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.

• 

  Heating Curve, Phase Changes, Intermolecular Forces, Freezing Point, Melting Point, Boiling Point, Heat of Fusion, Heat of Vaporization , Molecular Motion, Temperature, Heat, Specific Heat | High School, Middle School

  Activity: Simulation Activity: Heating Curve of Water Mark as Favorite (88 Favorites)

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

• 

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

  Lesson Plan: Stearic Acid Mark as Favorite (2 Favorites)

  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.

• 

  Molecular Motion, Heat, Phase Changes, Melting Point, Heating Curve, Freezing Point, Temperature, Graphing | High School, Middle School

  Lesson Plan: Modeling the Melting of Ice Mark as Favorite (33 Favorites)

  In this lesson, students will create a particulate model of matter that explains energy changes and transfer during a phase change.

• 

  Heating Curve, Phase Changes, Intermolecular Forces, Freezing Point, Melting Point, Boiling Point, Heat of Vaporization , Molecular Motion, Temperature, Specific Heat, Heat, Heat of Fusion | Middle School, High School

  Simulation: Heating Curve of Water Mark as Favorite (50 Favorites)

  In the May 2015 issue, students explore the heating curve for water from a qualitative and quantitative perspective. Students compare illustrations of each physical state depicted on the curve and calculate the energy required to transition from one state to another.
