Photosynthesis experiment device for teaching purposes

Abstract

The invention discloses a photosynthesis experiment device for teaching, which comprises an experiment box, the top of the experiment box is movably connected with a sealing cover, the bottom of the inner wall of the experiment box is movably connected with a plant potted plant, and the right side of the inner wall of the experiment box is A carbon dioxide detector is fixedly connected, and an oxygen detector is fixedly connected to the right side of the inner wall of the test box and positioned at the top of the carbon dioxide detector, and a light sensor is fixedly connected to the right side of the inner wall of the test box and positioned at the top of the oxygen detector, The right side of the inner wall of the experiment box and the top of the light sensor are fixedly connected with a lighting lamp, and the right side of the experiment box is fixedly connected with electric wires. Through the cooperation of carbon dioxide detector, oxygen detector, light sensor and lighting lamp, the invention solves the problem that the traditional experimental device cannot allow students to observe the changes of photosynthesis under different light intensities, thereby affecting the teaching efficiency.

Description

technical field [0001] The invention relates to the technical field of teaching equipment, in particular to a photosynthesis experiment device for teaching. Background technique [0002] Photosynthesis (Photosynthesis), that is, light energy synthesis, refers to the green plants containing chloroplasts and some bacteria, under the irradiation of visible light, through light reaction and carbon reaction (formerly known as dark reaction), using photosynthetic pigments to convert carbon dioxide (or Hydrogen sulfide) and water are converted into organic matter, and the biochemical process of releasing oxygen is also involved in the energy conversion process of converting light energy into chemical energy in organic matter. The impact of environmental factors on the intensity of photosynthesis” is the new high school biology course PPE version Compulsory one "Molecules and Cells" Chapter 5 Section 4 "Source of Energy - Light and Photosynthesis" An experiment set up in the "Applic...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a photosynthesis experimental device for teaching, which can allow students to intuitively see the oxygen changes produced by photosynthesis, and at the same time allow students to observe the changes produced by photosynthesis under different light intensities, thereby improving teaching. The advantage of efficiency solves the problem that traditional experimental devices cannot allow students to observe the changes in photosynthesis under different light intensities, thus affecting the teaching efficiency
