On Monday, we attended a speech given by a food scientist. He talked about why natural food is good for our health. I took many notes. On Tuesday, we had a special math class. Miss Wang didn’t just teach us formulas; she asked us to try different ways to solve real-life problems, like planning a budget. It was challenging but fun. Wednesday was the most exciting day. We did a chemistry experiment in the lab. Watching the color change from purple to silver was like magic! On Thursday, we learned how to search for information online effectively in the computer class. The teacher showed us how to tell if a website is trustworthy. Finally, on Friday, we learned to cook a simple healthy meal in the life skills class. It wasn’t easy, but eating what we cooked was the best reward! We shared all our experiences in a group discussion at the end of the week. We all agreed that when we connect what we learn with real life, learning becomes more meaningful and much more enjoyable. 1.What is the main purpose of the “Science and Life” week? A.

Let me tell you about one of my favourite activities last week. Last Friday, we had a very interesting science class. We did an exciting experiment about chemical reactions in the lab. During the experiment, I practiced how to take notes carefully to record every step and change. I was shocked to see the color change from purple to silver! It was like magic! Our teacher also taught us how to search for information online to understand the science behind it. I learned that science is not just in books, but full of surprises in experiments. I think it was the most fascinating class this month! I hope you also have interesting learning activities at your school! Yours, Li Hua 学科网（北京）股份有限公司 $
