What's the Difference Between Concentration and Solubility?
High schoolers discuss the difference between concentration and solubility as well as examine the difference in a hands-on activity. Using water and table salt, they experiment with solubility. They create different concentrations using...

To Be Salty Sea Ice Or Not
Students explore what type of solutions freeze. They design their own experiments to compare how fresh water and salt water freezes. In addition, they write their observations in a journal and complete analysis questions.

Exploring The Great Salt Lake
Second graders experiment with sand samples taken from a lake. They use this as part of an inquiry that is based on observations. The properties of the sand are observed in the lab and recorded in writing. Prior to the lab students...

Testing for Conductivity
Students test the conductivity of selected liquids and solids. They test the circuit by touching the two free ends of the wires together and add salt little by little recording the data after each addition. Finally, students predict...

Tracking the Salt Front
Students manipulate Hudson River salt front data from October 2004 -
September 2005 to locate the high and low points of the salt front for each month, They determine the range for each month, determine the modal range for each month,...

From Lake to Lake
Fourth graders investigate the formation of the Great Salt Lake. They conduct research using a variety of resources. The information is used to construct a timeline of the history. Each phase of history should include facts and...

What Do Salt Trucks Do?
Students predict what will happen to ice when salt is put on it. They make observations and discuss what actually happened to the ice. They relate their experiment to the salt trucks they see on the street.

Learning Lesson: Salt 'n Lighter
Students participate in a demonstration showing that as salinity increases density increases as well. They also examine the different densities of air. They discuss the amount of water displaced by large ships.

Salt: Up Close and Personal
Students view salt under varied magnifications so students can begin to construct the understanding that materials may be composed of parts that are too small to be seen without magnification.

Salt, To Use or Not To Use
Fifth graders develop a deeper understanding of chemical and physical changes. They explain how salt is made, used, and the affects it has on the body. They explain that salt in moderation is important to our health.
