Today I went on a school trip. We visit the science museum and it was really interested. We got to there so fast by train. We saw some farms and village along the way. At the museum, I learned a lot about robots. I didn't know they could play chess about us. It was so cool! Then the guide taught us how make a model robot. I take a lot of great photos, too. after that, I went to the gift shop but bought some lovely gifts for my parents. They weren't expensive. All at all, it was an exciting day.
