[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.

[Free Registration/Login may be required to access all resource tools.] In the following online tutorial students will learn to explain how an ionic bond is formed when electrons are transferred from one atom to another in terms of the...

Explore the phase change that occurs when ice is melting.

Freezing temperature, the temperature at which a substance turns from liquid to solid, and melting temperature, the temperature at which a substance turns from a solid to a liquid, are characteristic physical properties. In this...

The elements in Group 7 of the Periodic Table are called the halogens. They include chlorine, bromine and iodine. Learn about their properties and uses, then take a 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...

Young students are introduced to the complex systems of the Earth through numerous lessons on its natural resources, processes, weather, climate and landforms. Key earth science topics include rocks, soils and minerals, water and natural...

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...

Brief descriptions of physical properties, physical changes, and the process of sublimation. The three states of matter, melting point, and boiling point are described. There is one link on the page, which leads to an explanation of...

Observe the motion and temperature of water molecules in this simulation as heat is applied to a beaker containing an ice cube.

This lesson focuses on predicting chemical reactions using The Group 1 elements in the Periodic Table are known as the alkali metals. They include lithium, sodium and potassium, which all react vigorously with air and water. It provides...

In this lesson students will understand the difference between chemical and physical properties by studying the properties of water. Students will also understand how to perform the different laboratory techniques that go along with the...

In this interactive lesson, learn what the "physical properties" of matter are and how can they be measured and observed.

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

This lesson focuses on the physical properties of halogens, Group 7 elements on the Periodic Table. It includes the physical properties of the elements, provides a graph showing the melting and boiling points of the halogens, and links...

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 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.
