Tsunami formation demonstration teaching aid

Abstract

The invention provides a tsunami formation demonstration teaching aid, which is characterized in that a motor is arranged in the middle of a bottom plate at the lower part in a closed and transparentcylindrical cover body, a pot-shaped transparent disc which is gradually concave downwards is arranged above the cylindrical cover body, and the end head of a transmission shaft of the motor penetrates through the middle of the pot-shaped transparent disc and is provided with a propeller. During teaching, clear water can be injected into the pot-shaped transparent disc, and the propeller is drivento rotate through the transmission shaft of the motor, so that the clear water generates a tsunami phenomenon of pushing water around.

Description

technical field [0001] The invention relates to a teaching aid, in particular to a demonstration teaching aid for tsunami formation. Background technique [0002] In primary and secondary school courses, both geography and physics courses involve knowledge about earthquakes in sea water. The most important related knowledge is that it will cause tsunami phenomena on the coast. This tsunami phenomenon directly endangers the safety of life and objects along the coast. Therefore, , Preventing tsunami and ensuring safety after the occurrence of tsunami have always been the main topics of the research department, and it is extremely important to study and observe the formation of tsunami. In teaching knowledge, the formation of tsunami cannot be demonstrated at all. Understanding the relevant knowledge by oneself is extremely unfavorable for students to truly master the relevant knowledge. Contents of the invention [0003] The invention provides a tsunami formation demonstrat...

AI Technical Summary

Problems solved by technology

[0005] The present invention has the following advantages and effects: through the above technical scheme, since the motor is used to drive the propeller to rotate, and the propeller is placed in the middle of the pot-shaped transparent plate, after the clean water is loaded, the rotation of the propeller can drive the clean water to move around. This can visually demonstrate the phenomenon of tsunami formation, solve the problem that the current lack of teaching aids cannot intuitively understand the formation of tsunami, and help students improve their understanding of relevant knowledge during teaching
