PROBLEM TO BE SOLVED: To provide a teaching material device capable of visualizing even such a material state that temperature becomes low and the effect of intermolecular force is unignorable by using a molecule model and visualizing the material states of gas, liquid, solid, etc. SOLUTION: The teaching material device for visualizing the material state includes: a container 7 which is configured so that at least a part of a wall surface is transparent; a plurality of molecule models 8 which are stored in the container and can be visual; an operation part 5 which is provided in at least a part of the wall surface of the container and can shoot out the molecule models into the container. The molecule models are made of a material having high impact resilience and one or a plurality of magnets are incorporated in or on the molecule models, in at least a part of the plurality of molecule models. The operation part can adjust the shooting out speed of the molecule models and visualizes the material state by the movement of the molecule models based on the shooting out speed of the molecule models.
