Instructional Ideas

• Incorporate real-world information into the class' discovery of pH in the natural world by showing your town or city's annual water quality report
• It is common for seventh grade science pupils to have misconceptions about this subject matter, particularly acids; provide physical examples of acids they encounter every day in the foods they eat and products they use to back up the Gizmo presentation

Classroom Considerations

• A subscription is required to use all Discovery Learning videos and Gizmo presentation
• Be sure to pull together all materials required for labs and demonstrations in advance

Pros

• The potion demonstration provides a fantastic display of the concepts contained in the upcoming weeks of learning
• Testing soil and water pH brings a real-world element to the subject matter
• The included printable materials and video suggestions make this framework easy to execute

Cons

• None
