Lesson Plan: Balancing Chemical Equations - Grade Nine - Grade 09
Grade:09
Summary:Students will learn to explain how atoms and molecules form different substances during chemical reactions and how these processes require losing, gaining or sharing electrons. Students will correctly write chemical formulas and show how a balanced chemical equation must have the same number and types of atoms on each side of the arrow.

Standard: Physical Sciences
Benchmark: B. Explain how atoms react with each other to form other substances and how molecules react with each other or other atoms to form even different substances.
Indicator: 6. Explain that the electric force between the nucleus and the electrons hold an atom together. Relate that on a larger scale, electric forces hold solid and liquid materials together (e.g., salt crystals and water).
 
Standard: Physical Sciences
Benchmark: B. Explain how atoms react with each other to form other substances and how molecules react with each other or other atoms to form even different substances.
Indicator: 7. Show how atoms may be bonded together by losing, gaining or sharing electrons and that in a chemical reaction, the number, type of atoms and total mass must be the same before and after the reaction (e.g., writing correct chemical formulas and writing balanced chemical equations).
