Name of Corresponding Unit Plan: Artifact Conservation
Grade Level: 6-12
Common Core Standards:
WH/S.4. Determine the meaning of symbols, key terms, and other domain-specific words and phrases as they are used in a specific scientific or technical context.
WH/S.2. Write informative/explanatory texts.
Content Areas: Science
Recommended Length/Duration: 45-60 minutes – 60 minutes homework
Learning Goals: Students will understand the chemical reaction that results in corrosion like rust.
Students will find and describe examples of corrosion in their environment.
- Have a collection of items that exhibit corrosion. Introduce the concept of corrosion by asking students to describe what they see in the samples.
- Have students read together or independently the article on corrosion. Emphasize that corrosion is a natural process and will occur whenever the three components come in contact. Clarify the chemical nomenclature and reaction if this is not familiar to students.
- Review the assignment with students. Model how to describe and object by using one of the classroom objects as an example. Discuss where students might find additional examples around the school or at home.
- When students return have them share descriptions of the objects they found.
Assessments: Informal evaluation of worksheets for completeness and accuracy.
Materials/Resources: Corrosion worksheets (pdf)
Special Considerations: Students who are weaker readers can be paired with a stronger classmate.
Extensions: Students may want to find more examples of corrosion.
Students may want to learn more about ways to prevent corrosion in areas of interest; automotive, boats, bridges.
