Phototropism experiment box

Abstract

The invention discloses a phototropism experiment box. The phototropism experiment box comprises a main experiment box body, wherein the main experiment box body comprises a wooden box and a box cover, the wooden box and the box cover are correspondingly arranged, the wooden box further comprises a power supply module, a digital temperature controller is installed on the surface of one side of the wooden box, an LED lamp is installed on the surface of the main experiment box body, a through hole is formed in the inner side of the LED lamp, the LED lamp is installed on the outer surface of the wooden box or the box cover, light absorption cloth is arranged on the inner wall of the wooden box, a planting placement box and a beaker are arranged on one inner side of the wooden box, a heater is arranged at the inner bottom end of the beaker, and purified water is placed on the inner side of the beaker. According to the invention, the safety coefficient of the overall structure is high, and a USB interface and a socket with a safety door are adopted to form a power supply control unit, so damage caused by electric power can be limited to the maximum extent; and a stable constant-temperature system is further arranged, and temperature detection is arranged, so the safety of an internal structure can be guaranteed.

Description

technical field [0001] The invention relates to the field of biological experiment teaching aids, in particular to a phototropism experiment box. Background technique [0002] Experimental instruments are instruments used in specific experiments in natural science, mainly used in physics, chemistry, and biology. In the face of biological experiments, it generally refers to the use of certain instruments, materials and drugs under specific environmental conditions. Through scientific methods, purposefully observe and study the process of biological structure and life activity phenomena that are not easy to observe under normal circumstances. , [0003] Due to the limitations of the experimental site, time, method, etc., it is impossible for the students of Darwin and his sons to operate the phototropism experiment. The educational value of designing the phototropism experiment box is: it can let the phototropism experiment enter the laboratory and In the classroom, the situ...

Problems solved by technology

[0003] Due to the limitations of the experimental site, time, method, etc., it is impossible for the students of Darwin and his sons to operate the phototropism experiment. The educational value of designing the phototropism experiment box is: it can let the phototropism experiment enter the laboratory, enter In the classroom, the situation created by the animation courseware demonstration can be transformed into a situation for students to practice the real experience of the operation, and it can lead the students to go back to the path of scientific exploration. However, the existing phototropic experimental teaching aids are usually complicated and require the cooperation of various instruments operation, it is impossible to popularize the experimental unit to every student. At the same time, due to the low cost performance, a lot of energy is required to repair and maintain after the damage. Therefore, it is the current biological Teaching Demand Trends
