“The place where the invisible becomes visible” – In its structure, Horizon School has the Biology laboratory, which is equipped with all the necessary materials to conduct experiments in the function of the school curricula. There are performed laboratory works in the subject of biology. The Biology Lab offers the capacity to develop laboratory classes for a large number of students. The biology programme cannot be successful if it is not supported by the effective development of laboratory and practical work of students, and all of these provided in special classes, as well as included within regular classes, in the form of additional experiments, demonstrations, or experimental research tasks. Student-led work in the biology lab offers several advantages:

• It makes the subject more interesting and increases students’ motivation to learn;
• It helps the student to understand biological concepts, e.g., the student distinguishes more easily a physical change from a biological change if he sees them concretely in the laboratory;
• It draws conclusions based on experience;
• It improves critical thinking skills;
• It improves psychomotor and organizational skills;
• It helps students combine theoretical knowledge with the practical one;
• It helps them develop scientific research competence;

By engaging in simple scientific research, students will also develop scientific attitudes such as curiosity, defining and testing the method of problem-solving, evaluating, and modifying the conclusions obtained. Teachers are responsible for the safety of students during activities in the biology laboratory, for their promotion and motivation, for safety rules and responsibilities. They should always plan safe practical activities and guarantee the students’ safety conditions in accordance with the standards required for laboratory research. The Biology Lab is equipped with: 1.Visual tools Different schemes 1.Optical tools
