Classroom Resources: States of Matter

1 – 9 of 9 Classroom Resources

• 

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

• 

  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

  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

  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.

• 

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

  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

  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.

• 

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

  Lesson Plan: Salting Roads in Winter

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

• 

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

• 

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

  Lesson Plan: Pothole Science

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