The laboratories of FPUNE aim to provide high-quality and relevant education in knowledge, skills, and human values. Their success is based on a solid and committed teamwork for sustainable development, offering quality service in attending to students and professors during practical and research activities, thereby contributing to the development of theoretical and practical skills in the students education and acquiring attitudes that reflect a common sense towards professional development.

Laboratories are of great importance to students, as they carry out practical exercises that aim to link the theory seen in the classroom with the practice of the profession in real life, i.e., to verify that the phenomena seen in a theoretical way happen in reality.

This laboratory includes a set of equipment aimed at illustrating a wide range of applications in electrical engineering. Depending on the level of knowledge, students can carry out introductory as well as more complex and specific experiments. The laboratory is intended for the study of the principles of electricity, so that students can experiment with the physical principles observed in both linear and non-linear electrical circuits. The activities are carried out by the students autonomously or guided by a teacher.

Physics, one of the pillars of Technology, is a science that deals with understanding the most diverse observable phenomena of the Universe. "Studying physics" is an activity that therefore requires not only reading appropriate texts, but also observing, manipulating, and experimenting with phenomena. To understand the meaning of concepts and the scope of the laws and theories of physics, all the activity carried out in physics laboratories is essential.

In addition to observation and experimentation, the physics laboratory promotes learning observation and measurement techniques, and the correct use of corresponding instruments and equipment. For this, our laboratory has a set of practices with their corresponding work guides (of our own elaboration). In addition, planning and execution of projects (starting from the 2nd semester) are carried out, which promote exercise in innovation and self-management, which are extensively applied in all branches of science and technology.

In summary, the physics laboratory is a powerful didactic resource in the learning of every scientific-technological career, being therefore essential for engineering training.

The realization of laboratory experiments is a fundamental element in the teaching/learning process of Chemistry. Laboratory practices can help the student, in addition to developing basic skills in the use of experimental chemistry tools and data processing, to handle basic concepts, understand the role of direct observation in Chemistry and distinguish between the inferences made from theory and those made from practice; to highlight the process: observation of the phenomenon - obtaining experimental data - analysis of results - conclusions.

The practices in this laboratory aim to: Provide a broad and general experimental training, initiating students in laboratory work and serve as a space for "visualization" of what is studied in "theory classes".

Some of the experiments and projects carried out by this laboratory are:

• Chemical battery energy generators
• Hydrogen generator through electrolysis
