My name is Sandy. I work in a middle school. It is pleasant for me to plant in my free time. At the beginning of the school year, I had 1 useful idea-what if my students used a classroom garden 2 vegetables for our school lunches? The students could also learn about planting science.
I asked my headmaster 3 I could start a new plant lab garden or not. I was only in my 4 year of teaching, but she agreed.
As soon as my students went into the classroom, they got 5 . They all wanted to learn how to grow vegetables in this way of indoor gardening called hydroponics （水培）. This is great for areas that don't have much farmland. It helps people to grow healthy vegetables just about 6 .
To grow 45 beds of green vegetables, we need many things 7 growing cups, LED growing lights, fans and so on. 8 the students failed for the first time, none of them gave up. They kept on trying until they finally succeeded. It was interesting for 9 to watch the vegetables grow every day. And they all smiled happily when seeing students in other classes eat the vegetables they grew. My 10 new goal is that our school won't need to buy green vegetables any more.
