There are many fruit and vegetable gardens across the countryside. More students, at Madison Elementary School, are growing their own food in the gardens.
The vegetables are washed. Then kids can eat them at a salad party. They are also sold in the school dining hall for lunch. This month, students will plant tomatoes, potatoes, carrots, broccoli(西兰花) and strawberries.
Why are students learning how to grow food? Teachers want kids to learn healthy eating habits. Healthy food gives us energy. We need energy to grow.
Many kids are now trying new food and learning how to grow food. Lisa is the parent volunteer of the program. She says a lot of students have told her, “I like salad. I didn't think I liked salad!” Then those students have gone home and asked their parents to buy vegetables that they have tried at school.
Lisa's daughter, Lucy, is one of those students. She is in Grade Two.“I love the garden,”she says.“I didn't really like vegetables before we had the garden. Then we found out that gardening is cool. Now I like vegetables. My favorite vegetable is carrots.”
Zhang Heng was a famous scientist in the history of China. His invention Hou Feng Seismometer was a great success and it helped us understand the world better.
(AD 78-139) | It was invented. Zhang Heng was born in Nanyang in the eastern Han Dynasty. At that time, there were many earthquakes every year. People thought they were from ghosts. Zhang Heng, however, didn't believe it. He tried to find ways to study earthquakes for many years and in 132 he invented the first seismometer in the world. |
It was used. But at first, people didn't believe it and all laughed at him. In February, 138, Zhang heng's seismometer told there was an earthquake in the west of Luoyang. After four days, three earthquakes really happened in Luoyang area. It was believed to be useful from then on. However, it was lost 1700 years ago. | |
It was reproduced(再生产). Scientists have been trying to reproduce one like that. In 2012, the latest reproduced seismometer was successfully listed in Shanghai museum. It was reported to have been a little helpful during the earthquakes in Tangshan, Yunnan and Sichuan. It is hoped to be improved better soon and be able to predict coming earthquakes one day. |
