Below is a list of hands-on displays and activities that Mauna Loa Observatory has showcased at Earth Day fairs, special events, and at the office in Hilo during school class field trips. Each activity description contains background information about the educational basis of the activity, as well as photographs whenever possible. If you are a teacher or educator and would like to visit the MLO office with a group of students, please see our General Visitors page. Note also that our School Visits page contains special reports of past school visits to MLO. These are excellent resources for teachers that want to see how all the activities below could fit together during a field trip to MLO.

All MLO activities are in a printable Adobe Reader (.pdf) format.
