A page from the University of Maryland Physics Lecture Demonstration Facility. Provides directions for a teacher demonstration on the phenomenon of regelation. Shows apparatus and set-up; provides suggestions. Easily adaptable as a...

In this activity, Students can use an EasyTemp temperature probe to determine the normal melting temperature of ice. They will then study how the addition of salt to the melting ice affects its melting temperature. They will finally...

In this activity, students can use a calorimeter to measure the amount of heat needed to melt ice and determine the heat of fusion for ice. EasyData is needed for this activity.

Observe how ice and salt crystals interact by using salt to help adhere a string to the top of an ice cube in a glass of water, then lift the cube out of the water.

Allow your students to explore states of matter as they learn what causes frost to form on the outside of a cold container. Students will observe how liquid water can change to ice or water vapor in this lab. Lesson includes background...
