The utility model provides a combined optical experiment box teaching aid. The combined optical experiment box teaching aid is composed of a box body, three drawers capable of being drawn out completely are arranged in the box body and correspond to teaching aids of light reflection, light three-primary color and dispersion and light refraction respectively, and an experiment board is arranged at the top of the box body and corresponds to a light linear propagation teaching aid. According to the teaching aid, experiments of linear propagation of light, reflection of light, refraction of light, three primary colors and dispersion of light and the like are integrated in one experiment box through modular design, and the problems that an existing optical teaching aid is poor in integration, insufficient in light path visualization, complex in operation, poor in portability and the like are solved. The teaching aid has the advantages of simplicity and convenience in operation, clear light path, high interactivity and the like, is suitable for classroom teaching and autonomous exploration of students, and contributes to improving the teaching effect and the scientific literacy of the students.

A toy with flapping wings includes a main body, a drive assembly, and wing assemblies. The main body includes a frame, a first wing, a first connecting structure, a second wing, a third wing, a second connecting structure, and a wing connecting structure. The first, second, and third wings each include a wing skeleton and feathers. The first connecting structure includes a connecting seat, a connecting rod, and a connecting groove. Compared to existing technologies, the toy with flapping wings provided by this invention, through the setting of the first and second connecting structures, enables the wing assembly to perform mechanized reciprocating motion under the drive assembly, automatically forming wing flapping with a high degree of realism. Furthermore, by setting the first, second, and third wings and connecting them using the wing connecting structure, the curvature of the wings can be freely adjusted, facilitating the simulation of different wing-spreading states of organisms.
