teaching material for molecular formula of biotechnology

摘要

The present invention relates to a molecular structural learning textbook for biotechnology, wherein the teaching material is detachably attached to an iron plate board including a magnetic material, the attachment means comprises a plurality of element symbols on the surface to form a variety of atoms The disk member is characterized in that it comprises a connecting pin member located between the disk member and the element to perform the connection.;Therefore, the present invention can freely express various molecular structure formulas on the iron plate board by using the disc member and the heat binding pin, and thus it is possible to direct attention and learning ability to biotechnology as a learning material to children or students, as well as other things. It can also be used as an intelligence development ride.
