During the Spring Festival holiday, the 15th Spring Festival "Science and Technology Gala" theme education activities are being staged at the China Science and Technology Museum. Since its opening on February 12 to February 15, more than 100,000 visitors have visited the museum and experienced the charm of science in a variety of activities.
The "Science and Technology Gala" theme education activities set up four major sections: "Fun Science and Technology Year" in the educational activity space on each floor of the main exhibition hall, for young children to carry out wonderful popular science drama performances; The "Happy Science Year" focuses on the excellent science education projects of the museum over the years; The "Year of Love for China" launched the theme activity of "Science Market" in the ring corridor on the third floor of the main exhibition hall; Relying on a series of activities with the theme of "Intangible Cultural Heritage + Technology", the "Traditional Folk Customs Year" led the audience to experience the production of ink clay, paper-cutting and deep drilling and extraction of Zigongjing salt.
What kind of scientific experiment does Mr. Curly want to bring to you today? At 10 o'clock on the 15th, on the Dinosaur Square on the second floor of the Science and Technology Museum, the "Science Show Show" attracted many onlookers. The science and technology tutor made an invitation gesture with his left and right hands, and continued to sell Guanzi, "Actually, now in addition to me standing on the stage, a little assistant is also here, have you all seen him?" ”
There are smart little viewers who see the doorway, "It's air!" ”
That's right! Today I'm going to do some amazing experiments with my assistant. ”
As soon as the words fell, the teacher used the ping pong ball as a prop to demonstrate the different states of falling to the ground in the air and levitating above the tuyere of the hair dryer. Bernoulli's principle, which sounds a little tricky, is visually demonstrated.
The faster the fluid velocity, the lower the pressure. The teacher went on to explain, "The place surrounded by the air column blown by the hair dryer has a fast flow rate and very little pressure; The pressure is strong where there is no air column on both sides, so the small ball is like the 'meat' in the meat sandwich bun and is squeezed in this position by the surrounding 'bun'. Listening to this metaphor, the young audience laughed.
In the three-story corridor, many spectators are rushing to the "Science Market" with great interest. "Light travels in a straight line in the same homogeneous medium, and when light hits an opaque object, it is obscured by the object, so it forms a shadow in a place behind the object where the light does not shine. A boy read it in a low voice, his eyes rolled, and he had the answer in his heart, so he turned the cardboard over to verify, "Sure enough, it's 'immediate'!" The little boy excitedly shared this small achievement with his mother. Not only is science in idioms, but "science in ancient poems" and "science in lantern riddles" also attract many people to challenge.
Also on the "Science Market", the "Science Trolley" launched an interesting scientific activity, and the science and technology tutor showed the magic of magnetism at the same time, but also put forward questions, conjectures and hypotheses, make plans and design experiments, conduct experiments and collect data and other scientific methods and steps to the audience. Handicraft activities such as making lanterns for the Year of the Dragon and jumping dragons will fill the atmosphere of the Year of the Dragon.
In addition to offline activities, from February 1st to 29th, the Science and Technology Museum also continued to carry out the "Exploring the Science and Technology Museum - Science Children in Spring" short ** creation collection activity.
