1. 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

2. 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.

3. Molecular Shuffle Review Activity Examples: P = “I’m an Atom!” NO = one male and one female H 2 O = two females and one male or two males and one female

4. N Nitrogen

5. N 2 Atmospheric nitrogen

6. NO Nitric oxide

7. NO 3 - Nitrate

8. Na Sodium

9. NO 2 - Nitrite

10. NaCl Sodium chloride

11. NH 3 Ammonia

12. K Potassium

13. H 2 O Water

14. NH 4 + Ammonium

15. N 2 O Nitrous oxide

16. CaCl 2 Calcium chloride

17. Molecular Shuffle Review Activity Choose several different identifying traits. Call out complex chemical formulas, with several elements. Example: Ca(NO 3 ) 2 Call out the name of the molecule only. Create responses for students to identify micro and macro nutrients.
