Humidification

This 16-page resource, from the STEM Guitar Project, includes information about guitar humidity and dry guitar symptoms, a guitar humidifier construction activity, and a laboratory experiment. The activity teaches students how to make a guitar case humidifier and includes a 12-question quiz and answer key. "[The] experiment will aid students understanding of how proper humidity of wood plays a key role in guitar manufacturing." This resource has the following learning objectives:

1. Students will understand why wood humidification as it applies to wood of all types and specifically to guitars and guitar building is important.
2. Students will construct a guitar humidifier for their guitar case, keeping the guitar properly humidified.
3. Students shall conduct a lab experiment on wood samples subjected to 50% (normal), 90% (over-humidified) and 15% (under-humidified) conditions and analyzed for weight and size changes.
