Put on wireless headphones and listen to a beautiful song; Two mobile phones close together to instantly transmit picture data; Vehicle status changes, automatic alerts on the owner's mobile phone... In daily life, there is Bluetooth everywhere. Thousands of technologies, this is also one of the closest to us.
On July 23, the Children's Branch of Yangpu District Library launched the "Science Children's Innovation Camp" reading promotion activity, the theme of which is known as "Bluetooth". Young readers and parents came to the scene together to learn Bluetooth technology knowledge, make cool Bluetooth speakers, and have a deeper understanding of Bluetooth technology.
Why is Bluetooth called Bluetooth? What is Bluetooth technology used for? The keynote speaker threw out two questions as the opening to trigger the thinking of young readers. "Bluetooth, is it blue teeth?" "Bluetooth allows us to communicate over the air!"
In fact, Bluetooth technology is a wireless personal area network, originally created by Sweden's Ericsson, which has triggered a global research and development boom. Its name comes from a Danish king Harald in the 10th century AD, who was said to have contributed to peace in the Nordic countries and was known as the "King of Bluetooth" because he liked blueberries and dyed his teeth blue.
In the slow unfolding of the story, young readers understand the concept, origin and development of Bluetooth technology, and the speaker also shows you some application scenarios of Bluetooth technology in daily life, such as mobile phone Bluetooth, Bluetooth headset, Bluetooth mouse and keyboard, short-range file transmission, subway code, car Bluetooth, etc., so that everyone can really approach Bluetooth and understand technology.
After the popular science lecture, enter the Bluetooth speaker DIY session on the spot. With the assistance of teachers and parents, young readers picked up templates and toolboxes, manually threaded wires, installed buttons, drilled screws, and tightened nuts. After the production was completed, the parents turned on Bluetooth with their mobile phones, successfully found and connected to the homemade Bluetooth speakers, played songs, and welcomed the cheers of the children.
After the activity, many parents praised the activity and said that the children made Bluetooth devices by themselves, which not only strengthened their hands-on ability, but also enhanced their understanding and interest in scientific knowledge, which helped them to get closer to science, and hoped that the library could carry out more such activities.
It is reported that the "Science Children's Innovation Camp" science literacy theme series activities of the Children's Branch of Yangpu District Library integrate various forms such as scientific knowledge explanation, interactive demonstration, handicraft, etc., aiming to make science no longer boring, while cultivating and improving children's scientific quality, let everyone feel the charm of science together.
