The biology wall uses wood as its raw material, giving it a natural tactile feel while also incorporating modern pattern designs, greatly enhancing the layered environment of the garden area. Real specimen samples displayed on the wall surface through electronic means allow young children to observe and understand the changes throughout different growth stages of living organisms via game play interactions, more directly and effectively assisting teachers in introducing biological science concepts to early childhood education. By shaking the hand-cranked generator and pressing buttons for different stages, it will announce the growth processes of each respective phase.
