What homework did you do in the winter holiday? Now homework is not simply about exercises. It can be researches, experiments and even work experiences. Take a look at some students' special homework.
Studying snacks
One day, Wang Yang, from Shanghai Oriental School, was doing his biology homework. His teacher asked them to research the nutrients of different snacks. He bought 10 kinds of snacks. Then he checked their ingredient (成分) lists one by one and wrote down the amount of sugar, fat and so on, in each. ''We are told it is not good to eat too many snacks. They have high calories (卡路里). But we always pay no attention to it," he said. After analyzing (分析) each snack's ingredients, he realized it was true.
Wang Yang spent three days on the homework. But he said it was interesting. "I learned a lot. I collected the data (数据), created forms and wrote the report by myself."
Physics in real life
With some plasticine (橡皮泥), steel balls, a ping-pong ball, could you make a tumbler (不倒翁)? This is the physics homework of Huang Jiali, 14, of Shanghai 54 Middle School.
Huang first cut the ping pong ball in half. Then she put the plasticine and steel balls into one of them. The bottom of the tumbler was made. Finally, she also used the paper to make the "hat". "Next term, we will learn about the center of gravity (重心). This homework made me more curious about it," she said.
Learning on the job
While Wang and Huang did their homework at home, Ding Ling, 15, of No. 5 Middle School, had to go outside. She worked as a guide in the local museum. ''Everyone at our school has to take part in volunteering or other activities," she said.
Ding was a guide in the gallery (展馆) of coins. She got brochures (小册子) from the museum. In order to make the introduction more vividly, she still did research and added more information to her introduction. She worked three hours a day and had no time to take a break. But she felt it was a meaningful experience, "I learned how to do some research, and my communication skills are also improved." she said.
