Children usually go shopping and travel, see various bridges, and take high-speed rail. While feeling the brilliant achievements of the motherland's development, we also hope that children can understand the connection between bridges, high-speed rail and cities from a scientific perspective. In the process of perception, let children gradually understand the development state of the city they live in, understand the importance of science and technology to the motherland's development, and germinate national pride.
Mi Xiaotu customized National Day activity plan for the park , the theme is " Motherland Takes Off, I'm "Child" ", adding elements of the scientific theme, allowing children not only to exercise their hands-on ability, but also to draw scientific nutrition from it.
In order to better match children's age cognition, the activity plan is divided into two:
children in primary and middle classes, and the important link in water transportation - bridge.
The children of the senior class explore the king of land transportation - magnetic levitation train .

Activity process
① Experimental exploration: Bridge Engineer
Experimental materials
"Bridge Engineer" Material package: paper cup, clean water, A4 paper
Experimental steps
1. Put the two paper cups inverted, the cup mouth facing down and the bottom of the cup facing up on the table, comparing it to a bridge pillar. The distance between the two cups is about the distance between the two fists;
2. Fold the A4 paper in half from the middle and tear it into two Half, place half of the paper strips flat on two paper cups and use them as bridge deck;
3. Place another paper cup on the bridge deck to observe the phenomenon;
4. Fold the paper strips into corrugated shapes and put them on the two bridge poles again;
5. Put another paper cup on the folded bridge deck and observe the phenomenon;
6. Try to add water to the cup and continue to observe the status of paper bridge ;
Experimental principle
A piece of paper has very weak support and cannot support a heavy object that is many times heavier than it. However, when the paper is folded to form a crease, the weight of the heavy object is dispersed on multiple creases, and the paper bridge can support the heavy object not to fall off.
②Parent-child PK competition:
Who built the bridge is stronger?
rules: uses the scientific principles I just learned to build a paper bridge. Each family is a group to carry out load-bearing PK, and press it on the bridge with water cups, books, marker pens, , etc., who has a paper bridge with stronger load-bearing ability and win!
Share: The winning children talk about the process of making the bridge themselves and what methods have been tried to make the bridge stronger;
awards: awards the winning families , and awards the "star architect" certificates to children friends.Collect the bridge works designed by the children and display them in the garden wall to enrich the environment of the park;

Activity summary
Today's theme activity, children and parents carry out a parent-child creation PK competition around the "bridge". Everyone will find that scientific inquiry can be so interesting. The baby actively thinks actively and creates so many surprises; parents can also see that the baby is full of curiosity about things in life, and their interest in exploring things has been stimulated. In the exploration, they find that "science is everywhere". The baby's innovative consciousness is gradually sprouting. The teacher likes the growth of each baby!

activity process
① Awesome, my country: train flying in the air, arrange! On July 20, my country's 600-kilometer-hour high-speed maglev transportation system developed by CRRC and has completely independent intellectual property rights was successfully launched in Qingdao, Shandong. is amazing, my country! China's infrastructure has once again created a new miracle! The secret of magnetic levitation train↓↓ Children have played with magnets, the principle of magnet " repulses the same poles, and the opposite poles attract each other ". This principle is used by magnetic levitation trains. spread the rotating synchronous motor flattened, and then installed the rotor in the motor under the car; finally lay the stator and coil in the motor on the entire track and powered up, and the locomotive and the rails form a complete linear motor . In this way, the train can run on the track without relying on wheels to float, looking like it is "flying"! In the next activity, the children verified the principle of "the same pole repulses and the different pole attracts each other" through experimental exploration! ② Experimental exploration: Magnetic levitation refill Experimental materials "Magnetic levitation refill" material package: base plate, large ring, medium ring, small ring, circular jam paper, transparent cylinder, wooden stick, double-sided adhesive, ballpoint pen, large magnet, small magnet Experimental steps 1. Take out the base plate, paste the large ring on the base plate, and install the transparent cylinder in the middle of the large ring ; 2. Put a medium-sized ring on the other end of the transparent cylinder; 3. Use double-sided tape to stick the small magnet to one end of the wooden stick; 4. Use double-sided tape to stick the wooden stick on the medium-sized ring; 5. Take out the ballpoint pen, put two small rings on the top of the ballpoint pen, and stick a small magnet on the small ring.(Note to adjust the small magnet on the ballpoint pen and the small magnet on the wooden stick to attract each other); 6. Use double-sided tape to paste the round jam paper on the ballpoint pen; 7. Place a large magnet on the bottom plate, place the ballpoint pen between the large magnet and the small magnet, and observe what happens? 8. Remove the pen cover, gently turn the ballpoint pen, and observe what phenomenon is happening? Experimental principle magnets are magnetic and can attract iron items. The magnet has two poles. Putting the same two poles together will repulse each other, and putting the different two poles together will attract them. So when we do the experiment, we must let the two small magnets have different poles close to each other so that they can be attractive and make the ballpoint pens suspended in the air. 06 Activity summary Italian early childhood educator Dr. Maria Montessori once said: "I can't take children all over the world, but I can bring the world to the classroom." Today's activity, we explore the magnetic levitation train we have come into contact with in our lives, and learned the secret of it being able to "fly". The babies also tried to let the refills float, exercise the coordination of hands and brains, broaden the scientific horizons, satisfy curiosity, and learn new knowledge.
