Problems solved by technology

Due to the relatively low position of the experiment, students usually cannot see the process of the experiment and the teacher's operation clearly during the experiment, and students who are far away from the platform cannot see the experimental results clearly; especially when conducting physical experiments, students cannot see the circuit connection and the readings of instruments and meters; during chemical experiments, students cannot see the experimental process and experimental phenomena, which will affect the quality and effect of teaching

Abstract

The present invention discloses a teaching lecture experimental table comprising an experimental table body which is provided with fixed suction cup and a plurality of jacks, a tommy bar which is used for supporting laboratory apparatus and is arranged inside of the jack and is directly adhered to the teaching blackboard by means of suction cup. When lecturing the experiment, all the apparatus are placed on the tommy bar of the experimental table and the experimental position is higher, so that the experimental operation process can be intuitionistic displayed and the students can see the experimental phenomenon, the instrument state and the meter reading distinctly so as to improve teaching quality and effect, thereby the present invention has higher popularization value and social value.

Description

technical field [0001] The invention relates to a teaching demonstration experiment platform, which belongs to the field of teaching instruments. Background technique [0002] At present, when school teachers do demonstration experiments in teaching, they generally do it on the podium. Due to the relatively low position of the experiment, students usually cannot see the process of the experiment and the teacher's operation clearly during the experiment, and students who are far away from the podium cannot see the experimental results clearly; especially when conducting physical experiments, students can't see the connection of the circuit and the readings of instruments and meters; during chemical experiments, students cannot see the experimental process and experimental phenomena clearly, which will affect the quality and effect of teaching. Contents of the invention [0003] The purpose of the present invention is to provide a teaching demonstration experiment platform ...
