Lesson 5.1 Applied Chemistry

Preface
Chemical engineering is the profession that combines chemistry and engineering concepts to help solve problems related to world hunger, pollution of our environment, creating new materials, or meeting demands for energy. Chemical engineers develop low cost processes for producing ammonia, which make it possible for both poor nations and the United States to manufacture important fertilizers. They are instrumental in the production of virtually all pharmaceuticals as well as life-saving devices such as the artificial kidney or angioplasty catheters. They are working on ways to recycle plastics, reduce pollution, and develop new sources of environmentally clean energy. Chemical engineers have the background knowledge of chemistry coupled with an understanding of chemical processing that allows them to tackle most any chemical problem, from waste minimization, to environmental remediation, to pollution prevention, to clean-up of stack gases, or to purification of drinking water. Most major chemical companies hire chemical engineers to fill their technical positions in environmental engineering.

Concepts
1. Chemical engineering is concerned with design, construction and operation of machines that perform chemical reactions, separations or mixes, and fluid flow to solve problems and make useful products.
2. Chemical engineers apply the knowledge and discoveries of a chemist to solve real life problems.
3. Chemical engineers work in many industries including manufacturing, pharmaceuticals, healthcare, environmental, materials, and alternative energy.
4. Chemical engineers often work on teams with other engineers, scientists, and technologists

Performance Objectives
It is expected that students will:
• Describe the difference between a chemist and a chemical engineer.
• Apply science and engineering skills to make ice cream.
• Follow the design process to create an adhesive.
• Work with a team to solve an oil spill engineering simulation problem.

Assessment
Interpretation - Students will describe the difference between a chemist and a chemical engineer.
Application - Students will apply their knowledge of the design process to create an adhesive.
Perspective - Students will determine the best use of their resources to clean up an oil spill.
Self-knowledge - Through participation in group activities, students will understand and appreciate the importance of good communication skills, teamwork skills, and workforce development skills.

Essential Questions**
1. What does a chemical engineer do?
2. What is the difference between a chemical engineer and a chemist?
