Problems solved by technology

But these are still in the theoretical discussion, especially in school teaching, it is impossible to introduce them intuitively to students. Therefore, if a teaching aid that simulates a "global village" can be involved, this problem can be solved very well.

Description

technical field [0001] The invention belongs to the field of teaching aids, and in particular relates to a teaching aid for simulating a "global village". Background technique [0002] With the development of aerospace technology, human beings can leave the earth to travel into space. Due to the need for uninterrupted supply of food and fuel for human survival, and the extremely high transportation costs, human beings want to build settlements on Mars and the moon, where they can live for a long time. To survive, we must make full use of the conditions of the planets, and create a "nature" similar to the environment of the earth where they live-creating a "small earth". But these are still only theoretical discussions, especially in school teaching, which cannot be introduced to students intuitively. Therefore, if a teaching aid that simulates a "global village" can be involved, this problem can be solved very well. Contents of the invention [0003] The purpose of the in...
