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

  Lesson Plan: Salting Roads in Winter Mark as Favorite (3 Favorites)

  In this lesson, students investigate how the freezing point of water changes when salt is added. Many students know that water freezes at 0°C, and many believe that all substances freeze at 0°C. The investigations in this lesson help students understand why salt is spread on roads in cold and snowy conditions.

• 

  Phase Changes, Sublimation, Physical Change, Density, Observations, Temperature | Middle School

  Lesson Plan: Dry Ice Mark as Favorite (0 Favorites)

  In this lesson, students will investigate how dry ice undergoes a phase change from solid to gas, skipping the liquid phase under normal temperature and pressure.

• 

  Phase Changes, Physical Change, Observations, Temperature | Elementary School, Middle School

  Lab: Condensation Mark as Favorite (2 Favorites)

  In this lab, students will explore the process of condensation. Students will investigate how water vapor condenses, and then they will conduct a comparison test to see if cooling water vapor has an effect on the rate of condensation.

• 

  Observations, Combustion, Phase Changes, Experimental Design, Scientific Method | High School, Middle School

  Lab: Observing a Candle Mark as Favorite (16 Favorites)

  In this lab, students accumulate observations of a candle including a look at the combustion reaction's reactants and products.

• 

  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 (34 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 (52 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.
