I post these guiding questions on the board with my daily objectives. They help students become more aware of what they will need to know by the end of a lesson/unit.
Guiding Questions for the Arrangement of the Periodic Table Unit include:
What are some patterns (trends) found in the periodic table of elements?
How are elements on the periodic table organized?
How is the chemical reactivity of an element determined?
How does the arrangement of elements on the periodic table allow for the prediction of undiscovered elements and their properties?
How are groups of elements similar/different?
How are periods of elements similar/different?
How do groups and periods of elements compare?
