自己动手种的有机食物, 吃起来格外香！
Growing fresh healthy behaviors
How does your lunch taste (滋味)? For students at Philips Academy Charter School in the US, their lunch tasted fresh (新鲜的) and “proud (自豪的)”.
From Grade 6 to 8, students in the school had to grow their own lunch. On the small farm outside their kitchen, they grew crops (庄稼) like broccoli and many kinds of Asian greens.
To most students, it was the first time for them to see how food is produced (生产).
The greens grow under artificial lights (人造灯). Each month, students from different grades come to observe (观察) and water them. The farm produced about 8 pounds (3.6 kg) of leafy greens every three weeks. The fresh food was soon on the students' table.
"We harvest it and then it's used in the kitchen and the salad bar. And we're eating it during lunch, and it's fun,” said Yves Millien, 14.
And this organic (有机的) project is not only for teaching science. It really helped change students' behavior. Catkin Flowers, 13, hated green food before. She thought they tasted bad. However, after she grew her own crops, Catkin changed her mind.
"I made this and I want to eat it because it's good and I am proud of it,” said Catkin.
