### Description of Course Goals and Curriculum

This course covers the fundamentals of mass and energy balances. Balances are extremely important in all CBE classes, so it is crucial to learn the processes taught in this class. There is a midterm and a final. The most challenging aspect of this class was keeping the equations organized. There are many variables involved, and it can be a challenge to keep track of all the elements in a problem. Strong bookkeeping skills are very important. Make sure to keep all information organized. The class does not dive thoroughly into any topic, but instead covers a large breadth of topics, so it is important to keep up on the material. This class assumes you have a basic knowledge of physics and basic calculus. But since it is the first class you take in CBE, so it is not assumed you have much previous knowledge in the specific field.

### Learning From Classroom Instruction

Priestly closely follows the textbook in class. It is helpful to read the textbook before class because he quickly goes through the relevant equations. As he teaches, write down the equations. There are a lot of equations, so it is important to understand the application of each one and when it can be used. Occasionally he provides example questions, which are extremely helpful. In precept, example problems are presented and occasionally homework problems are completed. Precept is the time to ask questions and understand how equations are applied.

### Learning For and From Assignments

As you read the textbook, it is important to take note of all the equations in each chapter. All the example problems in the textbook are very helpful and often parallel homework and exam problems. Getting used to working through problems are very important to doing well in the class. As you do the problems, focus on the equations you are using, assumptions you are making, and more efficient ways to integrate your equations. There are problem sets due each week, which test knowledge of the processes and equations covered the previous week. They closely follow example problems in the textbook and involve lots of calculations, so I would recommend checking with a classmate before handing them in. As you complete your homework keep track of the equations that are commonly used and when they are used. This class also has group quizzes once a week. You can work with two or three other classmates. The quizzes test your knowledge of the equations taught the previous week. Quizzes teach you how to make use of information you are given, and figure out what equations can be used. The problems are very similar to homework problems. I would recommend reviewing the textbook chapters and reviewing your homework prior to the quiz. Quizzes are good way to check whether you are keeping up or need to spend more time on the class. Exam problems are much more challenging and involved than homework problems. I would recommend working through all your homework problems, going through all old exams, and extra practice problems.

### External Resources

Both the AIs and Prof Priestly have office hours. I would recommend going if you have questions on homework problems. Prof Priestly also offers solutions to textbook problems if you ask him, which can serve as valuable example problems if you feel like you need more exposure.

### What Students Should Know About This Course For Purposes Of Course Selection

This class is the first class of the CBE curriculum. The basic skills you develop in this class are used in all CBE classes. While at times the material will feel tedious and dry because all problems involve a lot of algebra, it gives you a foundation to learn and understand the juicier topics in future CBE classes.
