Instructional Ideas

• Extend the lesson by comparing different types of sand under a microscope and discussing why such variety exists
• Request free samples from each site for a more hands-on exploration of the sediments

Classroom Considerations

• Relies on prior knowledge of classification, sediment, and visual discrimination

Pros

• Offers tips for working with deaf students during the lesson
• Connects earth science, oceanography, and geology
• Provides extension ideas with many free resources

Cons

• None
