Plant cultivation observation device for biological teaching

Abstract

The invention discloses a plant cultivation observation device for biological teaching. The plant cultivation observation device is composed of a main teaching device body and a mounting plate. A processor is arranged at the lower end of one side of the main teaching device body; a fan is arranged at the upper end of the processor; and a heater is arranged at one side of the fan. A water tank is arranged at the lower end of the other side of the main teaching device body; a water pump is arranged at one side of the water tank; an atomizer is arranged at one side of the water pump; a ventilation hole is formed in one side of the atomizer; a humidity sensor is arranged at one side the ventilation hole; a temperature sensor is arranged at one side of the humidity sensor; and a plurality of cultivation boxes are arranged at one side of the temperature sensor. Besides, a groove is formed in the inner surface of the upper end of the main teaching device body; and a tempered glass plate is arranged at one side of the groove. With the cultivation boxes, various plants are cultivated in the cultivation boxes; and when teaching explanation of plants need to be carries out, students can carryout observation and make experiments practically, so that the teaching efficiency is improved.

Description

technical field [0001] The invention relates to a teaching device, in particular to a plant cultivation and observation device for biology teaching. Background technique [0002] Biology, referred to as biology, is one of the six basic disciplines of natural science. To study the structure, function, occurrence and development of organisms. and the science of the relationship between living things and their surroundings. Biology originated from natural history, experienced experimental biology, molecular biology and entered the period of systems biology. [0003] In the process of traditional high school biology teaching, teachers often only analyze the theoretical level of knowledge when summarizing the experiment and filling in the gaps, which makes other students often unable to understand the problems that may be encountered in the experiment intuitively and concretely, which not only increases the It not only increases the work intensity of teachers, but also greatly...

AI Technical Summary

Problems solved by technology

[0003] In the process of traditional high school biology teaching, teachers often only analyze the theoretical level of knowledge when summarizing experiments for students to check for omissions and fill in vacancies. This makes other students often unable to intuitively and specifically understand the problems that may be encountered in experiments. It not only increases the work intensity of teachers, but also greatly reduces the teaching efficiency, and cannot fully meet the teaching needs of high school biology teaching.
