I prepared bubble liquid with tea, detergent and sugar in advance, and made various bubble blowing tools: iron wire ring, bamboo tube, straw, hairy root ring and so on. The children couldn't wait to try all kinds of bubble blowing tools I brought, so they took part in the whole activity with great enthusiasm. Through the trial and exploration of each link, the children found that some of the bubble blowing tools I prepared can blow bubbles, and some can't. Finally, it is concluded that only tools with holes connected at both ends can blow out bubbles. In the last part of the activity, I asked the children to start work and transform some materials that can't blow bubbles into materials that can blow. The children actively tried, came up with all kinds of good methods and gained successful experience. For example: roll up the paper, poke out the paper ball stuck in the straw, roll up the hair roots and so on.
But no activity is perfect, and this activity still has some shortcomings:
1, self-made bubble water is not effective, which affects children's exploration to some extent.
Result.
2. The use of recording forms can be more flexible. In this activity, I made a big table and hung it on the blackboard for everyone to use. In fact, I can try to let my children have one and record their own exploration results.
3. I have also explored and discussed with children in the children's exploration session, but my personal concern is not enough.
The children were very involved in the whole activity, and I was happier when I saw the joy and affection on their faces. After the bubble blowing activity, the children are still reluctant to put down their tools, and the scientific activities are too attractive. In the future, I will organize more interesting activities for children to "play with middle school", and I will constantly improve my teaching ability and strive to do better!
