Experience popular science tourism in the United States.

Several group tours organized by domestic travel agencies failed to savor the natural and cultural connotations of scenic spots, and little was learned. Individuals have plenty of time to travel alone, but the content of the scenic spot explanation board is too brief, and the scenic spot rarely organizes activities aimed at enhancing knowledge. After coming back from American tourism, I deeply feel that the educational function of domestic tourism has yet to be developed.

The Colorado Grand Canyon in Arizona can be said to be a natural geological museum and a geology textbook. The 1,6-meter-deep Grand Canyon exposed the stratum structure like a gut, which created favorable conditions for popularizing geological knowledge. There are three kinds of geological tours in Grand Canyon Park: fossil tour, geological tour and geological tour. During the 6-minute, nearly 2-kilometer-long roaming, under the guidance of geological experts, tourists can look for marine fossils of 25 million years ago in the upper limestone of the Grand Canyon. Visitors can also see various strata and geological structures and witness the folds and faults in the strata. There is a school in Grand Canyon Park with the goal of popularizing geological knowledge. It organizes courses of different lengths for tourists for 1-8 days to learn about geology, biological system, local culture, birds, photography and plants. During the study period, junior and senior hiking cruises will be organized. Under the guidance of geological experts, you will enjoy the tranquility and mystery of the Grand Canyon in the morning, explore the ancient ocean and unpredictable wasteland, and observe strange animals and plants on the steep mountain road of 5km. In the bird watching activities organized by the park, under the guidance of experts from the International Eagle Watching Association, tourists observe the migration of eagles with binoculars and make records to understand the living habits and migration laws of goshawk, falcon and common eagle. Experts answer all kinds of questions about eagles. In the exhibition hall of the national museum of natural history in Washington, D.C., there is a room separated by plexiglass. In the middle of the room is a large animal fossil that has not been cleaned up. A paleontologist is observing carefully and gently brushing the sand on the fossil with a soft brush. He will never finish his work, because as long as a curious child pushes the door and walks into the hut, the scientist will stand up, listen patiently to the child's curious questions and then answer them seriously. It seems that this is the main work of ancient biologists in glass houses. In the "Popular Science Corner" of another museum, there are fossils of ancient plants and fish with clearly visible leaves on the table, which children can pick up and display carefully without worrying about being damaged. The Boston Computer Museum is a huge personal computer model with a mouse as big as a car and a monitor as high as two floors. Such a big computer keyboard can't be pressed by hand. Active children can dance on the keyboard to operate the computer. Children can also change their appearance in front of the images on the screen in other calculations, check whether there are grammatical errors in their speech, and experience the fun of flying a plane on the simulator. China often holds dinosaur exhibitions, and children can only see and touch these extinct behemoths. In addition to visiting exhibitions, the dinosaur exhibition held by new york State Museum in Albany, New York, also offers courses on dinosaurs for students of different ages. Through the 3-minute course, preschool children can learn how big and how heavy dinosaurs are, see the size and shape of their teeth and know what they eat. Students in grades 1-6 attend a 45-minute course to learn why dinosaurs became extinct and what else is threatening the survival of some creatures today. In the 45-minute course, students in grades 7-12 carefully study dinosaur fossils and bones, judge the size and walking mode of dinosaurs according to their footprints, and understand which animals existed in New York State before the extinction of dinosaurs and what caused them to become extinct in large numbers. The New York State Museum recreates the 19th century new york Harbor, the Alice Island Customs Building and the streets of new york with its spacious exhibition space. Anthropology, biology, geology and history researchers in the museum designed colorful activities for children. Primary school students went to Alice Island in new york to experience the feeling of immigrants in the early 2th century, and visited the streets of new york in 1895 to experience.
