The aims of this research were to evaluate the acute toxicity (LC/EC50) and the environmental risk of toltrazuril (TOL) and florfenicol (FFC) for plant Lemna minor, snail Pomacea canalicuta, fish Piaractus mesopotamicus and Hyphessobrycon eques and the microcrustacean Daphnia magna. The organisms were acclimated in room bioassay with controlled temperature according to standard to each one. They were exposed at nominal concentrations in static system. For environmental risk (RQ) was used the estimated environmental concentration (EEC) that is the dosage indicate to treatment and the lethal or effective concentration (LC/CE50) from each drug in acute exposure. FFC showed LC50;7d of 97.03 mg L-1 for L. minor; >100.0 mg L-1 for P. mesopotamicus and H. eques and EC50;48h > 100.0 mg L-1 for P. canaliculata and D. magna, and it was classified low risk (RQ = 0.01) for all bioindicators. TOL howed LC50;7d >100.0 mg L-1 for L. minor, 3.72 mg L-1 for P. mesopotamicus; 6.22 mg L-1 for H. eques and CE50;48h of 7.59 mg L-1 for P. canaliculata and 18.57 mg L-1 for D. magna, and it was classified low risk (RQ = 0.01) for L. minor and high risk for P. mesopotamicus (RQ = 2.68), H. eques (RQ = 6.22), P. canaliculata (RQ = 1.31) and D. magna (RQ = 0.53). Lemna minor was the bioindicator indicating of FFC toxicity and H. eques, bioindicator of the TOL. FFC is safety however and the use of TOL necessaries cautions to treat the wastewater before discard on the environment.

Our work aims to discuss the teaching of science in the context of informal education. Thus, we present and analyze the results of an initiative that we have made seeking to interest high school students to study sciences and technology. The Energy shows are activities which are presented in experimental demonstrations of science concepts to middle school students. After the show the students respond to a questionnaire which formed the basis for this study. The results indicate that the achievement of shows have had an impact on students.

Considering that Cultural-Historical theory has been gaining importance within Brazilian Psychology in the last decades, this essay aims at contributing to understanding its ontological and epistemological foundations, introducing the concepts of singularity, particularity and universality of the dialectics that exists between them. The analysis looks to explore the implications to Psychology, both as a science and as a professional practice, of the lukacsian indication about the need to apprehend the connections between singularity, particularity and universality as a condition for understanding the essence of phenomena. In that sense, this analysis brings light to the individual/society dynamics unity affirmed by historical-dialectical materialism, which contributes to overcoming of the dichotomies usually established between the poles of this relationship.
