Information about the Lesson 

Title:

Balancing Chemical Equations

Brief Description:

Brief review of balancing chemical equations. Positive reinforcement for the correct answer is an interesting fact about a reactant or product.

Subject(s) 
integration

(time required to complete lesson, e.g. "two 45-minute sessions")

Independent practice – may be used completely independently, or in a more structured setting such as a supplemental period of up to 45 minutes.

Goals:
(curriculum and unit related; National or State standards)

To demonstrate increased understanding of the relation between balancing of chemical equations and the Law of Conservation of Matter.

Objectives:
(measurable specific activities conducted by students)

To increase mastery of balancing chemical equations.

Teacher Materials/Resources:
(specific materials the teacher must have to conduct the lesson, e.g. Romeo and Juliet (video), American flag, etc.)

Procedures:

Balance each of the 11 equations in Classic Chembalancer, 10 equations in Review Chembalancer and 5 equations in Brain Boggle Chembalancer. Click on “show diagram” to actually see the number of each atom on each side of the equation. On completion of the Chem Balancer equations go to http://www.chemistry.ohio-state.edu/betha/chembal/shihome.html and be a crime scene investigator to solve the crime by balancing a series of chemical equations!

Assessment:

Immediate feedback is an interesting fact about one of the reactants or products in each equation.

Special Comments:

Students are often confused by the difference between atoms and molecules, by clicking “ show diagrams”  students can better visualize the actual atoms that make up each molecule
