Today, on November 30th, we went to the fog deer primary school to conduct the activities of students' hands -on activities. Today, the theme of the theme is experiments related to nano and optics. At the beginning, let the students understand what everyone often said. The unit, that is, the negative 9 of the 10, is very small, so today's main themes are small experiments with lotus leaves, nanohow ... and so on. Because the lotus leaves cannot be found temporarily, we look for taro leaves. Come instead of lotus leaves, and can also achieve the same effect. The Shangshui Dzi rolled on the taro industry. There is a paint on the market called nanium paint. Come and brush it when it is raining, so through this effect, we also have a paper cup with a slightly water with candles, so that there is a layer of carbon at the bottom of the paper cup. By the way, the carbon on the bottom of the cup was brought up. After that, the experiment of the optics was a non -Nie ear lens, a magic film and a rainbow film.
