The magical dishwashing liquid in the kindergarten class
There were some interesting science experiments in the kindergarten's activity about dishwashing liquid. For example," The Long Bubble Worm " was based on the scientific principle that dishwashing liquid was used as a surfacing agent to reduce the surface tension of water and form a water film. When the small holes on the paper towel were blown, the water film would form many small bubbles and become bubble worms. The required materials included a bottle, rubber band, wet tissue, clean water, scissors, and dishwashing liquid. The operation process was to cut open the bottom of the bottle, cover the tail with wet tissue and fix it with rubber band, add clean water and dishwashing liquid, stir evenly, and blow into the bottle mouth. There was also a science experiment in Ambo's kindergarten. By putting a finger stained with dishwashing liquid into the water with pepper powder sprinkled on the surface and observing interesting phenomena, the children could understand the effects of water, pepper powder, dishwashing liquid, and so on. At the same time, they could also know the dangers of using chemical cleaners and the benefits of using dishwashing liquid. In addition, during the self-made bubble water activity, he found that adding an appropriate amount of dishwashing liquid, washing powder, sugar, etc. to the water and stirring it evenly could blow bubbles. These activities could stimulate the curiosity and desire of small children to explore the things around them. Read more exciting novels for free

Reflection ** 1. ** Command Validity ** - Reflect on whether the instructions you give are clear and concise enough, and whether the child can understand and execute them quickly. If you find that the child is not responding well to certain instructions, you need to adjust the way the instructions are expressed or give more examples. 2. ** Habit Formation Effect ** - Observe the child's habits, such as whether his study habits have improved and whether his routine habits have been consolidated. If there were problems with the child's habit formation, it was necessary to analyze whether it was due to inappropriate educational methods or individual differences, and then adjust the educational strategy. 3. ** Activity Suitableness ** - Review whether the activities organized meet the needs and development level of the children in the upper class. If the activity is too simple or difficult, it is not conducive to the child's growth.
