To enrich students school life and help us learn more about space exploration, our school organized a visit to the City Museum on the other day.
At the beginning, some pictures and videos about space exploration were shown to them. By watching them, we learned a lot about many great achievement that had been made in our country. The astronauts' devotion to the space exploration of our country leaves a deep impression on us. Afterwards, we experienced a life and work of astronauts, like how they do in our space station. All the teachers and students were very excited, try and touching everything.
Such a great success the activity that it was highly spoken of. Hopeful, there will be even more activities like this.
