"Purple Young" Liqi Juvenile ｜ Zhiqu brainstorming, happy technology one summer day2

On the afternoon of July 26, the enthusiasm of Liqi teenagers opened as usual as usual. Everyone arrived as scheduled, met with the neighbors and governance innovation parks, and together with the familiar partners to welcome the summer summer camp "smart brain storm, happy technology technology One summer "the next day.

In order to cultivate the creative thinking and hands -on ability of young people and enhance their scientific literacy, today's activities and closely focusing on practical operations are divided into Lego fight and the "gravity downstairs" scientific experimental activities in the second half.

First of all, social workers introduced the geographical environment of the Qinghai -Tibet Plateau through rich pictures. It was towering, strong, and sufficient in sunshine ... It is the place where Lego competed with the hero "Tibetan Antelope" today.

"Tibetan antelope has a pair of long pointed corners and a special nose. They are often hidden in caves, or hidden in shallow pit, only exposing the head, which can avoid wind and sand, but also find enemy damage. "Through the explanation of social workers, teenagers have a preliminary understanding and understanding of the appearance characteristics and living habits of Tibetan antelopes.

In order to better protect the Tibetan antelope, what can we do? Establish a natural reserve, create a "wild animal channel", and report on poaching. With the unremitting efforts of people, our "plateau elves" Tibetan antelope is no longer endangered, from 50,000 in the past to At the same time as the gratifying results of the current gratifying results, we should also remember history and continue to be the "guardian" of the Tibetan antelope.

Next, social workers gave the young people four themes, namely the homeland of Tibetan antelopes, habitats, setting up a living channel, and defending Tibetan antelope. After the group discussion, everyone quickly started Lego's cooperation.

Combined with the completed works, social workers guided young people to write the inspiration and ideas of creation on the description card one by one, and displayed and shared them in turn to realize the collision and exchanges of thinking.

After a short rest, the event in the second half also kicked off.

"Without the existence of gravity, what will the world look like?" "Have you ever heard the story of Newton and Apple?" Around today's scientific experimental theme, social workers tell the basic meaning of gravity and in the young people. Applications in daily life. The "little experiments" here listened converge, and couldn't wait to show their skills.

After understanding the relevant knowledge of gravity, social workers led young people to start making use of gravity -driven devices -gravity downstairs machines.

The assembly parts of the gravity downstairs are seven capsules, one steel ball, two axes, eight rubber bands, two thin cardboards, and two large cardboards. Two parts are composed of two parts, namely stairs and capsules.

According to the assembly steps, the teenagers have fully played their own hands -on capabilities. After a while, everyone's gravity came down and built it.

Next is the experimental session of the gravity. Put the capsules equipped with steel beads on the top of the stairs. Flip the bottom of the bottom to go downstairs. At the same time as the experiment was successful, young people also learned important scientific knowledge: the direction of gravity is always vertical, and the gravity of the object is proportional to the quality of the object.

In laughter and laughter, the teenagers not only built their own creative works, but also learned the scientific principles of wisdom. What challenges will the "Liqi Juvenile" usher in tomorrow? let us wait and see!
