STEM stands for science, technology, engineering, and mathematics. STEM is important because it pervades every part of our lives. By exposing students to STEM toys and giving them opportunities to explore science and technology, they will develop a passion for it.

Biology has more features than any artificially made machine. Bionics is a science that mimics the special skills of living things. Bionics learns about the structure and functional principles of living things to develop new machinery and new technologies, or to solve mechanical engineering problems.
