Science Probe II Technology Activities
1.You have learned that electroplating is valuable in providing
protection from corrosion on metals. When a metal is electroplated, the
metal to be plated, or protected, is made the cathode. A process called
anodizing is when a metal is made the anode, in order to give metal a
protective coating. Conduct an Internet search to find out about anodizing,
a. What metal(s) it is used on?
b. What solutions are used for anodizing?
c. What chemical reaction takes place during anodizing?
d. How do it protects the metal?
e. Are they any other pertinent information needed to understand the
Prepare a multimedia presentation to inform your classmates
of what you have learned. Below is a web site to get you started:

2. Over 90 percent of all used lead-acid batteries are recycled in the
United States. Conduct an Internet search to find out more information
about the recycling of these batteries. During your search, look for answers
to these questions:
a. How is the lead removed from the electrolyte in the battery?
b. What chemical reaction occurs to remove the lead from the electrolyte?
c. What is done to the lead electrode to make it reusable?
d. What role does the government (local, state, or federal) play in
the recycling procedure?
Prepare a multimedia presentation to inform your classmates of what you
Activity 11A – Use a word processing
program to set up the two-column table as directed in this activity. Complete
the first column by yourself. Then discuss this column with your group,
making changes in the column as necessary. As you read the sections in
this chapter, take your notes on the computer. When you have completed
the chapter, transfer your notes to a presentation program and share with
classmates what you have learned. Print the document, and secure it in
your SCIENCE PROBE Logbook.
