As teachers, we’re always on the prowl for ideas and resources for our classrooms. You can tell who the teachers are at amusements parks (figuring out the physics principles at work), on the beach (identifying shells and other critters), and on the hiking trails at state and national parks (with binoculars and guidebooks or ID apps). We take (drag?) our families and friends to museums, science centers, zoos, nature centers, botanical gardens, and arboretums. Even at historical sites, we can find applications of science to share with our students (for example, while my husband and I were exploring the history of the Gettysburg Battlefield, I was also photographing the lichens on the monuments). We stop the car to photograph interesting rock outcrops or fantastic cloud formations. Our souvenirs include rocks, sand samples, fossils, pressed wildflowers, maps, brochures, books, and thoughts and reflections about improving what we teach. (Be sure to follow local procedures about sample-collecting, though. Photographs are good!)
My husband got used to the fact that our vacations always had a science component! And I enjoyed sharing my experiences with students.
