Practice of Handmade Rocket in Kindergarten

The picture of practicing manual rocket in kindergarten is as follows:

1. Prepare a paper jam.

2. Roll it into a cylinder.

3. Cut a hole at one end for easy pasting.

4. Cut another semicircular cardboard and fold it into a cone.

5. Then stick it on one end of the cut cylinder with a glue stick.

6. The two most protective right-angled triangles can be pasted on both sides to make a handmade rocket with a straw inserted in the middle and blown out.

Rocket is an aircraft propelled by the reaction force generated by the rocket engine injecting working medium. It carries all propellants by itself, does not rely on external working medium to generate thrust, and can fly into or out of dense atmosphere, so it is a vehicle for space flight. Rockets are divided into sounding rockets and launch vehicles according to their uses.

Sounding rocket is a kind of rocket, which is used to send scientific instruments into the upper atmosphere near the earth in a parabolic trajectory and make them enter near-earth space. The basic structure of sounding rocket includes arrow body structure, power device, stable tail, etc. Sounding rockets are mostly single-stage or two-stage rockets, and there are also three or four-stage rockets.

The advantages of doing manual work:

1. Manual activities are a way for us to explore knowledge and promote brain development. The more we do, the more we can learn.

2. Handwork can bring fine movements to children, that is, the unity and coordination of thinking consciousness and muscles. The progress from rough manual to fine manual can improve children's practical ability step by step, and children can control their movements more accurately through manual work.
