1.设计实验实验目的:了解西红柿电池的发电原理.实验器材:西红柿一个、大小相同的铜片(或者铜币一枚)和铝片各一个、耳机一个.2.实际操作(1)用双手转动西红柿,一边转动一边用手轻轻挤压,直到感觉它变得有点“柔软”.(2)将铜片和铝片分别插入西红柿,直到铜片和铝片的一半都在西红柿里,使两者的距离保持在0.5 cm范围内.注意:无论是金属片,还是铜币,一定要选择外表看起来比较光亮的,如果没有光泽,可以用
1. Design Experiment Experiment Objective: To understand the principle of tomato battery power.Experimental equipment: a tomato, the same size of copper (or a copper coin) and a piece of aluminum, a headset .2 practical (1) with both hands Tomatoes, squeeze gently while turning, until it feels a little “soft.” (2) Insert the copper and aluminum pieces into the tomatoes until half of the copper and aluminum pieces are in the tomato Keep the distance between the two within 0.5 cm Note: Whether it is metal, or copper coins, we must choose the appearance looks more shiny, if there is no gloss, you can use
