Esta pesquisa teve como finalidade relatar experiências em laboratório, especificamente o Laboratório de Geografia Física - Pesquisa (LabGeoFis-Pesquisa), localizado no Departamento de Geografia, no Centro de Ciências Humanas, Letras e Artes, da Universidade Federal do Rio Grande do Norte. Procuramos relatar, de forma concisa, as principais técnicas aplicadas ao trabalho laboratorial, enfatizado a temática da Geografia Física. Para tecer essas considerações, nos fundamentamos em autores como Venturi (2005) e Rudio (1990), os quais tratam sobre teorias e procedimentos relacionados às práticas de laboratório e a pesquisa descritiva e experimental, respectivamente. Para realizar esta pesquisa, levamos em consideração os trabalhos e as experiências desenvolvidas pelos alunos de bacharelado e licenciatura do primeiro período do curso de Geografia. Os resultados aqui obtidos, nos mostraram a importância dos conhecimentos teóricos aliados com a prática de laboratório.Palavras chaves: Laboratório; Experiência; Técnicas. ABSTRACT This research had the purpose of reporting laboratory experiments, specifically the Laboratory of Physical Geography - Research (LabGeoFis-Search), located in the Department of Geography, at the Humanities, Letters and Arts Center of the Federal University of Rio Grande do Norte. We try to report, in a concise way, the main techniques applied to laboratory work, emphasizing the theme of Physical Geography. In order to make these considerations, we base ourselves on authors such as Venturi (2005) and Rudio (1990), who deal with theories and procedures related to laboratory practices and descriptive and experimental research, respectively. To carry out this research, we take into account the work and experiences developed by the baccalaureate and undergraduate students of the first period of the Geography course. The results obtained here showed us the importance of theoretical knowledge allied with laboratory practice.Keywords: Laboratory; Experience; Technique. RESUMENEl propósito de esta investigación fue reportar experimentos de laboratorio, específicamente el Laboratorio de Investigación de Geografía Física (LabGeoFis-Pesquisa), ubicado en el Departamento de Geografía, en el Centro de Humanidades, Letras y Artes, Universidad Federal de Río Grande del Norte.

Many schools, for various reasons, find it necessary to go to considerable expense to accumulate and maintain nature and museum exhibits for the use of their pupils in science and art classes. The Western Pennsylvania School for the Blind, being located only two blacks from the Carnegie Library and Museum in Pittsburgh, is availing itself of the many opportunities offered by this proximity, rather than attempting the accumulation of a collection of its own. The teachers are urged to co-ordinate and supplement their work by actual and consistent use of the Museum exhibits. This has been facilitated by the whole-hearted cooperation of Miss Jane White, Assistant Curator of Education, and Mrs. Emily A. Burke, Docent in the Department of Education at the Museum. We feel that the establishment of library and museum habits in our pupils is also important, and so encourage them to seek these sources of information on their own initiative as well as in assigned classes. The use of Carnegie Museum exhibits by the science classes, under the direction of Mr. Fred A. Hunt, has inspired Mrs. Burke to set forth in the following article the ways and means by which she is rendering to us this valuable but gratuitous service. B. S. Joice, Superintendent, Western Pennsylvania School for the Blind.
