## Legacy Cycle

OBJECTIVE
By the next class period, students will be able to:
* Understand general principles of chemistry.
* Understand stoichiometry
* Demonstrate the ability to solve quantitative problems.
* Recognize the role of chemistry in real world issues.
* Demonstrate knowledge of common reactions and reaction mechanisms of the elements & compounds.
The objectives will require that students be able to:

THE CHALLENGE
You are hired as the laboratory manager at a major pharmaceutical company. Your first task is to purchase chemicals for the aspirin production line in order to produce 125,000 aspirin bottles per day.
GENERATE IDEAS
* How much aspirin is in each bottle?
* What is the total amount of aspirin needed to be produced?
* What chemicals are used in the production of aspirin?
* Is any product lost in the production line?
MULTIPLE PERSPECTIVES
Provided by professor at the end of the Generate ideas portion. (You tube presentation, research articles, etc.)
RESEARCH & REVISE
* Examine typical aspirin daily production
* Examining typical production line % loss
* Examine reactions for aspirin production
* Balancing chemical equations
* Computing moles of B from mass of B
* Converting moles of B to moles of A
* Examine unit conversion factors
TEST YOUR METTLE
Online homework assignment related to model
GO PUBLIC
* Homework and exam problems that apply the module concepts to unrelated applications
** Examples:
*** An automobile engine produces energy by the combustion of gasoline, which is primarily octane, C$_8$H$_{18}$. Being a concerned citizen for your local carbon footprint you decide to compute the amount of carbon dioxide that is emitted from your car in one year.
*** The compound diborane (B$_2$H$_6$) was at one time considered for use as a rocket fuel. As an engineer you need to know how many grams of liquid oxygen would a rocket have to carry to burn 10 kg of diborane completely?
