The object of the present invention is to help understand osmosis concept by showing osmosis, one of biological phenomena, through a molecular motion model.;In general, students have difficulty in osmosis and have very low levels of understanding. One of the reasons is that it is impossible to visually confirm the molecular motion causing osmosis.;The present invention is composed of a colorless transparent rectangular acrylic box 100, beads S as a molecular model, and a wire mesh 200 as shown in FIG. When the box 100 is strongly shaken to the left and right, a small ball S moves through the wire net so that the osmosis phenomenon can be easily seen by the students. In other words, if the box is shaken while keeping the height at first as shown in the first figure, the height of (B) will increase. This means that a small bead on the (A) side can easily pass through the net, while on the (B) side with a large bead the amount of small beads that can pass through the net is small, It is because of interference.;By observing simulated molecular motions and their results using this experimental setup, students can easily understand osmotic phenomena and by working directly with the device, students can easily understand the osmotic phenomena and have the device You can increase your interest and participation in learning by working directly.
