Caracterização física e química dos frutos nos diferentes quadrantes da planta e germinação de sementes do portaenxerto cítrico tangerineira ‘sunki’

The tangerine 'Sunki' are highly relevant for the Brazilian citrus industry by presenting important traits for genetic improvement and to be considered a great portaenxento. In this context, the objective of the present work to study the characterization of the fruits of citrus rootstock 'Sunki', depending on the position on the plan and also the germination of their seeds. The physical characteristics evaluated were fruit weight, longitudinal and equatorial diameters of the fruit longitudinal diameter / equatorial diameter, number of buds per fruit, weight of buds and bark and number of viable seeds per fruit. As for the chemical characterization was evaluated titratable, acidity, soluble solid, "Ratio", pH and vitamin C. For the evaluation of these variables, the fruits were obtained from the northeast, southwest, northwest and southeast quadrants. Regarding the evaluation of seed germination, different doses of gibberellic acid and Stimulate were used. The seeds extracted from ripe fruit, washed, dried in the shade and stored in BOD. Immediately after, they were treated for 24 hours with plant growth regulators. After soaking, the seeds were placed in a germinator in germitest paper. After initiation of the germination process, the evaluations were performed daily until the thirty- fourth day. Fruits of 'Sunki'mandarin with uneven as the fruit position within the canopy, the use of gibberellic acid and growth promoter is promising for commercial use on seed germination of this rootstock.

Ensino de física e energia: estudo de possibilidades didáticas na educação básica

This monograph has the inspiring theme of the Energy education, concept of extreme importance to physics, but that is rarely addressed in Brazilian schools. We bring a discussion of the problems faced in teaching this subject and present this analysis of how this issue is addressed in some textbooks that are part of the material available to students of basic education in our country. We also discuss a didactic proposal to the Physics Teaching using for this experiment. The proposal considers the student protagonist of the learning process being the builder of his own knowledge. For this proposal selected three experiments (solar plate, looping and looping coffee cups) analyzed from the point of view of energy that have the intention to leave this clearer content and close to the students. Here is the end of this work the application of the examination of this proposal in a public school in full-time education in the municipality of Rio Claro - SP

Física e música: o uso de canções como ferramenta auxiliar no ensino de física

In this work we present a didactic proposal to use song lyrics for Physics Teaching aimed to High School level. Based on the work proposed by Zanetic (1990) that Physics is also Culture, we understand that its influence extends beyond the scientific boundaries, reaching spheres of knowledge where its presence is less obvious, such as the arts, especially Music. Based on proposals for Ramos and Gomes (2013), activities were conducted in two groups of second year of high school in the city of Rio Claro, each with an approach. In one of the classes the students received as material the lyrics of the songs printed and the other students were given a table along with the lyrics. In these materials the students identified physical concepts present in the songs Nuclear Shelter of the São Paulo band Premeditando the Breque and Manhattan Project of the Canadian band Rush. We observed during activities an improvement in the participation of students in theoretical discussions, probably due to a more favorable context for students to express themselves assigned by us to the activities with the songs. After performing the activities we demonstrated that you can enter the Music in the classroom not only as entertainment but as an aid in research and understanding of physical concepts

O ensino de física e a curiosidade epistemológica: o uso de experimentos de eletricidade em atividades educacionais

We analyzed with this work the importance of using experiments in the classroom, especially the low-cost experiments for better learning of Physics, discussing the context where this discipline is inserted, which in general, has been presented to students in a traditional, mechanistic way. We worked with the electrostatic theme and low cost didactic experiments, focusing on the pizza electrophorus. About the handling of this experiment, we can see the surprise and curiosity in students, depending on how it is used in didactic activities in order to make it meaningful to the student. We discussed how the curiosity can be harnessed in the classroom, the types of curiosity according to Freire, how to overcome the curiosity to become epistemological, the physics involved in the experiment and the teacher's role in this context

História da ciência no ensino de Física: um estudo sobre o ensino de atração gravitacional desenvolvido com futuros professores

We report here some outcomes of a research related to a didactical experience aiming to integrate the History of Science to the Physics Teaching, taking as background the historical development of the gravitational attraction. The research, of qualitative approach, is a case study and it was carried out in a sample of eleven students belonging to an undergraduate physics program (called licenciatura in Brazil) designed to from High School physics teachers in a São Paulo State Public University. We tried initially to reveal prospective teachers’ conceptions in order to provide a prepare that was used to guide the activities from the reality’s diagnosis. The aim was to promote discussions on the existence and persistence of alternative conceptions, on the historical evolution of the subject gravitational attraction, through readings and debates of texts contemplating recent subjects on the Science Education research, in order to generate dissatisfaction with traditional teaching models. The future High School physics teachers were asked to construct their own teaching proposal, through the development, in real situations, in a High School, of a minicourse based on: debates and synthesis developed in University classroom, the History of the Science and the student’s alternative conceptions. In this paper we will analyze future teachers’ alternative conceptions, the development of the course proposed, and details of the mini-courses taught by the prospective teachers in real situations, among High School students, its coherence and the posture changes observed in them.

Aplicação de texto paradidático no ensino de física como possível alternativa para a inclusão de aluno com deficiência visual

The work completed on the use of para-didactic texts do not address the issue of education in a state that considers the presence of students with visual impairments. Therefore, this article discusses an innovative situation, investigating if the use of para-didactic texts provide the necessary conditions for the inclusion of students with visual impairment in physics education classes. The response indicates a discreet participation of these students, however a significant one, in this application the students were motivated and interested in all of the topics discussed. This prudent participation may have occurred for reasons such as shyness and the behavior of teachers, as they tended to to be more talkative to these students.

Diversidade religiosa e formação de professores de ciências: uma discussão em Habermas e um caso no ensino de Física

This article brings a discussion of the implications of religious diversity on science education as well as on teacher education. To orientate our discussion, we adopt as framework the ideas of German philosopher Jürgen Habermas on the political relationship that should govern relations between a naturalistic culture and different religious cultures. We also present a research with future teachers of physics, which aimed at investigating the positions taken by the future teachers towards non scientific models presented by students about the origins of the universe. We tried to identify, especially, the expectation of these future teachers would demonstrated about the contributing of the lifting of such models in class by students. We were able to find that most of them believe that the manifestation of these ideas could bring contributions to the discussion in the classroom. We also found that teaching practices based on communication, questioning and dialogue of the undergraduate course done by the prospective teachers has generated an ownership by the undergraduates of these practices and their potential application in other situations and other discussions, including inter-religious.
