Mobile Laboratory of Environmental and Anatomical Sciences was presented at CEST, Chile

Within the framework of Science Week, on October 20, the Expobio Mobile Laboratory of Professor Samuel Nuñez Cook, known as #profesorsamnc, was installed in the CEST(Centro Educativo Salesianos Talca) North Headquarters theater, where the teacher gives a guided tour exhibition or free viewing of five stations of samples related to biology, whose objective is to disseminate biological sciences, from a morphological and anatomical perspective, at different spatiotemporal scales. This activity was coordinated in its logistical scope, by Nicolás Ulloa, science professor at CEST. 

The Laboratory was attended by students of the basic and intermediate HC modality. As transversal learning objectives, the students were able to classify, analyze, interpret and synthesize the information, establishing relationships between the different subjects of scientific and social learning, and also increase the elements to protect the natural environment and its resources as a context of human development, demonstrating the interest in knowing reality and using knowledge to do so. Professor Samuel explained each station to the students. The students were very enthusiastic about attending this Laboratory, demonstrating curiosity and interest in learning about living beings, objects and/or events that make up the natural environment and its resources. 

The first contained mollusks, arthropods in general and Chilean insects, and samples of mollusk shells, arthropod arians from around the world and the Chilean insectary. 

The second station highlighted vertebrates through skeletons and taxidermy, samples of fish, amphibians, non-avian reptiles, birds and mammals. 

The third station consisted of the discipline of human anatomy, through anatomical models and study texts. Samples of human body models: brain, head, torso, skeleton; anatomy texts and atlases, dissection tools, organ conservation samples: goat intestine and pig heart; manipulation of a preserved biological sample such as brain and heart. 

The fourth station was about microscopy, with samples through a digital microscope, explaining the importance of this instrument for science. Histological set samples of 100 different plates to observe. 

The fifth station contains fossils with samples of marine fossils, megalodon tooth, fish, marine invertebrates and sperm whale bone. It should be noted that this Laboratory can be contacted with Professor Samuel on Tiktok: @profesamnc; Ig: @profesamnc; and in his emails:;
