Balloons are bulging and colorful, the air is invisible, colorless and tasteless, and they can't be caught or touched. To let children feel the existence of air, they must use concrete objects, which are deeply loved by small class children. According to the cognitive characteristics of small class children, the scientific activity of "playing games with balloon babies" was designed, so that children can explore and perceive the existence of air in free games and know the reasons why balloons suddenly fly and wander around. Experience science and explore the joy of hands-on practice.

Activity objectives:

1. Know that the balloon is full of air.

2. Blow into your face to feel the air.

3. Feel the interesting phenomenon that air rushes out of the balloon.

Activity preparation:

Some uninflated balloons, ten inflated balloons, and some pumps.

Activity flow:

The children explored and found in the situation of playing balloons and participated in the activities with great courage. The activity has achieved remarkable results, which fully embodies the practicality and value of the operation materials. It can be seen that the target positioning of this activity is more accurate. Experience the fun of scientific activities.
