Learning Intentions

• You can organize elements from the periodic table according to properties.

• You can determine patterns between properties of elements from the periodic table.

• You can read and analyze various organizations of the periodic table to determine which is best to find an element based on its name and which is best to find an element based on its properties.

Content Standards being covered:

Use the periodic table as a model to predict the relative properties of elements based on patterns of electrons in the outermost energy level of atoms. (HS PS1-1)

Use a model to predict the relationships between systems or between components of a system (HS PS1-1)

Student understands how the periodic table is organized, how that organization can be used to determine an elements properties and trends of properties on the periodic table.
81. The periodic table is arranged by increasing atomic number.

Journal Entry:

What are some different ways the periodic table could be organized differently? How would the new organizations help people use it as an efficient resource?
