Abstract:

Based on the chemical fingerprint development method, this science popularization project has designed a variety of different science experiments to show the principle and characteristics of chemical fingerprint development to the science popularization target comprehensively. In the mode of science popularization, the project innovatively combines "online + offline" mode and "home + laboratory" environment, which breaks the limitation of time, space and equipment in traditional science popularization and greatly expands the scope and breadth of science popularization. In addition, in the implementation of specific science popularization, the project focuses on the improvement of scientific and cultural literacy of science popularization targets, opening up the public's vision, and achieving scientific and effective disinformation.
