Atom Economy - Synthetic methods should be designed to maximize the incorporation of all materials used in the process into the final product.
Less Hazardous Chemical Syntheses- Wherever practicable, synthetic methods should be designed to use and generate substances that possess little or no toxicity to human health and the environment.
Designing Safer Chemicals= Chemical products should be designed to affect their desired function while minimizing their toxicity.
Design for Energy Efficiency - Energy requirements of chemical processes should be recognized for their environmental and economic impacts and should be minimized. If possible, synthetic methods should be conducted at ambient temperature and pressure.
Use of Renewable Feedstocks - A raw material or feedstock should be renewable rather than depleting whenever technically and economically practicable.
Design for Degradation - Chemical products should be designed so that at the end of their function they break down into innocuous degradation products and do not persist in the environment.

The lesson is inquiry based, and is well set for inclusion into the curriculum for chemistry, biology (ecology), or basic physical science. The first lesson from this module relates glucose production from cornstarch to ethanol fuel production from corn stover. Another lesson uses a calculator-based colorimeter interface from the Vernier Company to quantify the hydrolysis of starch to sugar by salivary amylase. In this lesson saliva is added to a starch solution containing a couple of drops of iodine. Light initially doesn't pass through this solution. If the absorption decreases after the addition of the saliva, this means more light is passing through and the starch is being hydrolyzed (broken down into maltose and glucose). The third lesson again uses colorimetry but
Design for Degradation - Chemical products should be designed so that at the end of their function they break down into innocuous degradation products and do not persist in the environment.
Real-time analysis for Pollution Prevention - Analytical methodologies need to be further developed to allow for real-time, in-process monitoring and control prior to the formation of hazardous substances (The Twelve Principles of Green Chemistry, 2010).
Teacher Prep: This module focuses on the production of sugar (glucose and maltose) from cornstarch.

The lab will involve testing household products to use as cleaning agents. During the lab students will wear gloves and if necessary masks. Educational goal: To understand the 12 principles of green chemistry and the scientific method Student objectives: Students will understand and apply the 12 principles of green chemistry. Materials: Vinegar, baking soda, bleach, and household cleansers Time required: Three days of research, brainstorming, and finally a lab day. National standards met: S1,

The students did the same with lemon juice and milk of magnesia, after cleaning out their pipets and the wells. The students then recorded the color changes on their worksheet. It was rewarding to see students carefully test these substances with great curiosity and care, as they could not guess what the result would be. The more challenging part came when the students had to mix acidic and basic solutions,
The Title I reading instructor will become familiar with the Plato Learning content library. The Title 1 reading instructor will begin supplementing classroom instruction with the mini classroom lab using software from Plato Learning. Title I reading instructor will assess classroom performance and modify lab use accordingly. The STAR Reading test results will be evaluated. Survey results on student attitudes towards reading and learning will be compared to April 2007 results. The state standard scores
In the book, Project management: strategic design and implementation, David I. Cleland and Lewis R. Ireland report "a review of the results of projects in antiquity reveals evidence about how several historical projects originated and developed" (p. 4). 1. The first of this type of evidence, known as artifacts, typically came from human workmanship. These could have been structures, tools, weapons, or items of substance of archeological or historical interest.
The trainer will then focus on the steps to be taken to develop new skills. For example, if the trainer wants to talk about motivating, leading, negotiating, selling or speaking, it is best to start with what the learners do well before showing some chart on Maslow's theory, Posner's leadership practices, or selling skills from some standard package that has been develop elsewhere. Many foreign trainers make grave errors
