  Lab: Lemon Ice Mark as Favorite (0 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.

  Lesson Plan: Stearic Acid Mark as Favorite (0 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.
