Instructional Ideas

• Have a contest to see which group can build the boat with the least corrosion
  

Classroom Considerations

• Sheets of different metals and different coatings are necessary for the activity, as well as other materials; see the resource for the complete list
  
• Learners should be familiar with corrosion from the associated lesson
  

Pros

• Provides a rubric for the project
• Includes a list of discussion questions to use with the class
