Last Saturday, my classmates and I went to the Chinese Academy of Sciences, which was a precious chance/golden opportunity to get close to science.

The moment we arrived at the Chinese Academy of Sciences, we were warmly greeted by a friendly expert standing at the entrance. Excited and happy, we clapped our hands and everyone was eager to explore the amazing scientific world. To have a better understanding of daily basic science, we attended a professional lecture themed Life and Water. A professor introduced the topic in such great detail that we all gave full attention and took a lot of notes.

The highlight of the visit was the hands-on experience in the science lab. Under the guidance of the expert, we got involved in a medical experiment with great care and enthusiasm. Observing the samples through the microscope, we, for the first time, got to know how anti-cancer drugs were developed and what awesome achievements our hardworking scientists had made. We also felt proud of the medical progress of our country.

Before we left, we invited the expert to take a group photo with us as a reminder of the fantastic visit, everyone wearing a big smile. Through the meaningful activity, we all agree that science plays an important role in our life and we will study hard to take advantage of it to make our world a better place.
