WATER CHEMISTRY

Here is a good worksheet for 5th grade scientists. In it, they look at a bar graph that shows the freezing point for a variety of liquids. Then, they are given a scenario of a certain liquid melting and freezing, and must determine which...

Have you ever wondered why cities in cold climates put salt on the roads to help keep ice from forming? In this chemistry video, Sal explains why the introduction of salt molecules suppresses, or delays, the formation of ice crystals...

Here is a fun display that will help your physical science fanatics understand freezing points and crystal formation. Use rock salt, sparkling water, and ice to create a -10¡C bath. Place full bottles of soda into the slurry to supercool...

Water is powerful! Because it expands as it freezes, if it does so in a closed system, tremendous pressure can be created. All it takes is a little break to cause the system to explode! It's unlikely that you would submerge a pipe full...

What are the issues surrounding water quality? Viewers of this short presentation gain information about the importance of clean water, the lack of fresh water, water contamination, and ways that engineers treat water. 

Students work with three stations to demonstrate the properties of water. They explore water's boiling point, freezing point, and its ability to store heat.

Challenge your sixth graders with this lesson about the freezing and boiling points of water. In these activities learners graph temperature data, read and analyze information, and identify the freezing and boiling points of water and...

Chemistry concepts come alive against the backdrop of the Sochi Olympic Winter Games! Here is a captivating clip to share with your chemistry kids. It teaches how the bonds in a water molecule contribute to the formation of a...

What a fresh approach to learning about water! Chef Jamika Pessoa explains the chemical composition of this vital compound, what happens when heat is added or removed, and how much water is contained in different organs and...
