(Reporter Yang Chuanzhi Correspondent Chen Wei) When the temperature rises, the human body will shed a lot of sweat to dissipate heat and maintain the balance of body temperature, so have you heard that leaves also sweat? On the morning of March 10, 2022, the children of the second class of Huayuankou Kindergarten in Huiji District, under the leadership of the teacher, did a magical little experiment "Plant Sweating!" Let's verify that the leaves also sweat.
During the whole experiment, the children actively participated, carefully recorded, and gained a lot.
The items to be prepared for the experiment are very simple, a pot of plants, a transparent plastic bag, a pair of scissors, a ball of hemp rope, and a number of plastic bags.

Select the leaves of the plant
Experimental materials
Set of plants
Tie plants with different numbers of leaves tightly in a transparent plastic bag and place on a balcony for 2 hours. The children were particularly excited while waiting for the results of the experiment, they wondered what magical things would happen, and as they waited, the children kept wondering what would happen. "Some say the leaves are going to wither because he can't breathe anymore." Some people say that "the water in the pot may be sucked dry by the plants", right? Some say that "four leaves of the plant sweat more", some say "a leaf of the plant sweat more", time a minute and a second passed, when the children saw a thin layer of small water droplets in the plastic bag, everyone rushed to record the observation results, found that the larger the leaves of the plant or the more leaves the more leaves, the more the plant sweated, and rushed to remove the plastic bag covering the plant, to touch the leaf "sweat".
Early childhood science education is the scientific enlightenment education of young children, which is to perceive and observe the material world through children's own activities, and to find problems through hands-on operation. Although the small experiment is simple, it can learn a lot of interesting scientific knowledge, and the children play in the school, play in the middle school, and have fun.
