Module 4—Batteries and Balance
In This Module
Lesson 1—Voltaic Cells and Batteries
In Lesson 1 you will learn about the scientific principles involved in the construction and function of voltaic cells, a type of commercial electric cell.
You will investigate the following lesson questions:
- How much do you rely on batteries in your everyday life?
- What are the components of a voltaic cell?
Lesson 2—Design of Commercial Cells
In Lesson 2 you will investigate the construction of different types of commercial and consumer cells used by society, and you will consider the environmental impact of your personal battery use.
You will investigate the following lesson question:
- Why are there so many different designs and types of electrochemical cells?
Lesson 3—Electrolytic Cells
Lessons 1 and 2 will explain the chemical change that occurs within a voltaic cell. But how can you make a cell rechargeable? In Lesson 3 you will learn about rechargeable cells and why some cells are rechargeable and others are not.
You will investigate the following lesson questions:
- What is an electrolytic cell?
- What chemical and energy conversions occur within an electrolytic cell?
Lesson 4—Commercial Applications of Electrolytic Cells
In Lesson 4 you will learn about industrial applications of electrolysis, and you will learn how this technology can be applied to the extraction of elements and to the refining and electroplating of metals.
You will investigate the following lesson question:
- What are some of the practical applications of electrolytic cells?
Lesson 5—Quantitative Relationships in Cells
In Lesson 5 you will record and analyze qualitative changes within electric and electrolytic cells.
You will investigate the following lesson question:
- What are the important quantitative relationships within operating electric and electrolytic cells?
