Read the passage and study the graphics concerning Melting Point and Thermodynamics of Double-Stranded DNA and then answer the five question quiz.

Engage students in the study of the ocean and saltwater with these activities. Students will see that saltwater has different physical properties than freshwater - mainly density. This lesson can serve as a springboard into other...

A page from the University of Maryland Physics Lecture Demonstration Facility. Provides directions for a teacher demonstration of the effect of an ionic solute upon the freezing point of water. Shows apparatus and set-up; provides...

[Free Registration/Login may be required to access all resource tools.] What happens to matter when it melts and the definition of melting point.

That heat flows from hot to cold is an unfortunate truth of life. People have put a lot of effort into stopping this fact, however all they have been able to do is slow the process. Working in groups of three to four, students will...

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...

[Free Registration/Login Required] Explore how solutes can keep roads clear of ice in the winter by learning how different types and concentrations of a solute affect the freezing point of a solution.

Zander is on a camping trip. Join him, and help him learn about boiling and melting points.

Explore survival strategies of animals in freezing climates. Investigate the role of glucose (sugar solution) when used as an antifreeze and the relationship between temperature and metabolism.

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...

Answer the thermal energy transfer questions correctly, and advance around the baseball diamond.

A page describing (in part) the distinction between energy, temperature and heat. Includes a graphic illustrating the quantity of energy needed to transform water between various states. Methods of thermal energy transfer (convection,...

Students will look at what happens to different types of matter when they have a change of state.

Help solve the mystery and find the missing crystal. Following the activity, read more about chemical and physical changes, and then take a quick quiz to check for understanding.

Five chemistry lessons about phase changes between the states of mattter complete with handouts and animations.

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...

The concepts of melting point and freezing point are explained on this site.

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.

An indexing page for the HyperPhysics site. This page includes links to a variety of pages at the site which contain information related to phase changes. Each individual page consists of informative graphics and clear explanations.

This lesson will introduce a phase change diagram, and show how a substance changes from one phase to another. It is 1 of 3 in the series titled "Phase Changes."

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...

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.

This lesson will introduce a phase change diagram, and show how a substance changes from one phase to another. It is 3 of 3 in the series titled "Phase Changes."
