Classroom Resources: States of Matter

1 – 7 of 7 Classroom Resources

• 

  Mixtures, Melting Point, Freezing Point, Phase Changes, Freezing Point Depression | 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, 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.

• 

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

  Lesson Plan: Modeling the Melting of Ice

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

• 

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

  Activity: Simulation Activity: Heating Curve of Water

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

• 

  Freezing Point, Physical Change, Temperature, Exothermic & Endothermic, 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.

• 

  Acids & Bases, Melting Point, Freezing Point, Phase Changes, 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, 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.
