PORTABLE BIOLOGICAL LABORATORY COMPLEX FOR EDUCATIONAL ACTIVITIES AND METHOD FOR ITS USE FOR DYNAMIC OBSERVATIONS OF PLANTS Russian patent published in 2023 - IPC G09B23/38 

FIELD: educational activities.

SUBSTANCE: declared solution relates to means for teaching in natural sciences and can be used for teaching and project activities in biology, for students to carry out observations, laboratory and practical work in the school biology course and the environment, allowing them to observe the processes of plant life cycles. A portable biological laboratory complex for educational activities is claimed, consisting of a container with a bottom and a working support platform located above the bottom. The container is formed by a rising transparent lid and a transparent back wall, and the side walls of the container are made of fixed and movable walls, where the container lid is formed by a segment of a hollow cylinder, its edges are fixed to the end part of the movable side walls, fixed coaxially on the immovable side walls. In the space between the bottom and the working support platform there is a control board, to which a water pump for irrigation is connected with power, and various sensors and a fan are also connected. All elements of the housing are made of transparent material, and on the fixed side wall on its outer side there is a bracket to which the water pump is attached. This side wall has a through hole into which a water supply hose is inserted, the end of which is connected to the outlet pipe of the water pump, and a water intake hose is connected to the inlet pipe of the water pump. A smartphone can be installed on the bracket with an emphasis on this hose and in this way take many pictures of plant growth from the same angle at specified intervals, and based on the results of observations, compile the pictures taken into animation.

EFFECT: expanding the scope of technical teaching aids, as well as the possibility of more effective use of the installation for growing plants in the educational process and observations, including dynamic observations of plant growth using students’ own smartphones.
