Chemistry, Fertilizer, and the Environment Lesson Matter of Fact

•What is matter?• How does nitrogen change in the

nitrogen cycle?• Activity: Nitrogen Cycle Game• Review: Molecular Shuffle

Molecular Shuffle Review Activity• Choose an identifying trait that will

represent different elements.Examples: hair color, gender, pennies, etc.• Call out molecular formulas—atoms,

molecules, or compounds.• Students gather in groups to represent the

number of atoms required for each molecular equation.

Molecular Shuffle Review Activity

Examples:P = “I’m an Atom!”NO = one male and one femaleH2O = two females and one male or

two males and one female

Molecular Shuffle Review Activity

• Choose several different identifying traits. Call out complex chemical formulas, with several elements. Example: Ca(NO3)2

• Call out the name of the molecule only. • Create responses for students to identify

micro and macro nutrients.
