Science Alive: Melting Point Simulation
Percy Julian and Josef Pikl used the fact that melting point-the temperature at which a substance changes from a solid to a liquid-is a characteristic property of a substance to prove that the British chemist Robert Robinson could not...

Texas Instruments: How Low Can You Go?
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...

Texas Instruments: Heat of Fusion
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.
PBS
Pbs Teachers: Rising Ice Experiment
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.
