Properties of Salt

Crystals are more than meets the eye! Can learners tell them apart simply by observation? As they examine five samples with a magnifier, they find that appearance alone is not enough. This serves as an introduction to a mini unit on...

Blue-tinted water is added to unknown liquids that have been tinted yellow to find out how they interact. This is a memorable activity that is part of an investigation on the properties of liquids, which is part of a unit on the...

Once investigators have learned how their mystery liquids interact with water during the preceding activity, they now use their observations to identify them. This is an ideal conclusion to the mini unit on the properties of water. 

Fifth graders study the properties of metals and use them to identify different properties.  In this metal properties lesson students complete a demonstration .

Students research background knowledge of the Great Salt Lake prior to a field trip. They identify specific wild life at the Great Salt Lake on the field trip and identify the islands in the Great Salt Lake. They present their...

Students discuss certain properties of salt and how it is used every day as well as harmful uses. They experiment with salt to see it conduct electricity, form crystals and water freezing temperature. They complete a worksheet to record...

Now it becomes crystal clear why the unit is called Mixtures and Solutions. The fifth installment of a six-part unit explores mixtures and solutions. After viewing a demonstration on mixing pebbles with water, salt with water, and...

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.

Students predict, observe, and explain the details of salt as they view it under a variety of magnifications. They observe salt with the naked eye, and then under a hand lens, microscope, and the electron microscope.

Crystalline structures have unique properties that are sure to wow classes. A hands-on lesson has learners form their own crystals using a variety of compounds. They then choose a variable to investigate to determine its impact on the...
