We propose a tangible experiment support system that facilitates safe and independent chemistry experiments. For safe experiments, the system displays messages that alert a student to avoid a possible accident based on the operational context. Simultaneously, the system is designed to facilitate active thinking, in which the key concept is multiple interpretations of a message, to avoid dependency on the system in future experiments. The concept of an information presentation with three-dimensional ambiguity, i.e., semantic, spatial and temporal, is presented. A prototype application A3 (A-CUBE) is presented, which extracts various operational contexts in a chemistry experiment from the usage of experimental apparatus and materials. We report the usability experiment and discuss the feasibility of a presentation with ambiguity for active thinking. Additionally, the design principle of a message with semantic ambiguity and future work are presented.
