Journal Entry:

If you were to drop a spoonful of salt, NaCl, into a glass of water, what would happen? If you were to drop a gold ring into a glass of water what would happen? What do you think is different about the atoms of these two substances?

Learning Intentions

• We will learn what conductivity is and how to test conductivity of substances.

• We will learn what solubility is and how to test solubility of substances in water.

Closing Task:

You can make predictions about the conductivity and solubility of certain substances.

Content Standards being covered:

Students can use the periodic table as a model to predict the relative properties of elements based on the patterns of electrons in the outermost energy level of atoms.

Student understands why bonding occurs between atoms, what types of bonds form when different elements interact, how the bonds form and properties that arise as result of the bond forming.
