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 Formulas, Equations and Conservation of Mass Unit include:
How are chemical formulas used to determine the number of atoms of each element found in compounds?
What is the purpose of a subscript in a chemical formula?
What is the purpose of coefficients in a chemical formula?
What evidences indicate that a new substance has formed as a result of a chemical reaction?
What are the components of a chemical equation?
After a reaction, how do the reactants and products in a chemical equation compare?
How are balanced chemical equations and the law of conservation of mass related?
What is meant by “balanced” equation?
