Inspire children to use scientific thinking to infer the basic principle of rocket going to heaven.

Activity preparation:

1, children have 1 balloons, and each group has 1 wooden boats with small bottles.

2. 1 pictures of rocket launch.

I learned to draw a simple rocket.

Activity flow:

1. The teacher guides the children to experiment and leads to activities through experiments.

Operation method: children loosen the opening of the balloon filled with air and the balloon flies forward.

Guided discovery: encourage children to observe repeatedly and find out the principle of balloon flying forward.

Children's discussion: What makes balloons fly?

Teacher's guidance for children: gas flows backwards to form airflow, and the recoil of gas pushes the balloon forward.

2. Experiment: How does the ship move forward?

Operation method: fill the small bottle with water, cover it, and then put it in a fixed position on the wooden boat with the bottle mouth facing backwards. After putting the homemade boat into the basin, take off the bottle cap and the boat will move forward.

Guided discovery: encourage children to experiment repeatedly, focus on observing the direction of the ship's movement and water flow, and find out what power the ship relies on to move forward.

Children's discussion: what power does the ship move forward? What other objects can you see moving by reaction in your life?

3, through the experiment, leads to the activity content:

Show pictures of rocket launch and ask: What is this, children? Through the experiment just now, what can you say about pushing such a big rocket into the sky and making it fly so fast?

4. Observe the actual situation of rocket structure and rocket launch, and make a reasonable judgment by using experimental findings.

(1) The teacher pointed to the rocket part and guided the children to observe and understand the rocket top cabin, fuel tank, engine and booster rocket one by one.

Summary: The rocket is divided into two parts. The upper part is loaded with satellites and various space probes, and the lower part consists of a huge fuel tank and a high-power engine, with two booster rockets next to it.

(2) Guide children to observe the working conditions of the rocket launch and make reasonable inferences.

Q: What is burning at the tail of the rocket? What happened to the whole rocket? Which direction does the flame spray? Guess, what power did the rocket rise into space?

Summary: when the rocket's fuel burns, it produces a huge flame, which is injected backward at high speed, forming a powerful airflow. The recoil of the airflow and the great power of the engine push the rocket forward quickly and rise into space.

Outreach activities: organize children to visit the Children's Science and Technology Museum, and affirm their enthusiasm for exploration through the visit and the staff's explanation, and encourage them to continue learning and explore again.
