Nesta pesquisa procurou-se verificar as características físicas e químicas de bebidas lácteas preparadas com três concentrações de soro de queijo Minas Frescal (30, 40 e 50%), empregando-se dois tipos de culturas lácticas: uma tradicional para iogurte (YC-180) contendo cepas mistas de Streptococcus salivarus subsp. thermophilus, Lactobacillus delbrueckii subsp. lactis e Lactobacillus delbrueckii subsp. bulgaricus e outra (ABY-1) contendo cepas mistas de Lactobacillus delbrueckii subsp. bulgaricus, Lactobacillus acidophillus, Bifidobacteria e Streptococcus salivarius subsp. thermophilus. Constatou-se que as bebidas lácteas apresentaram diferença estatística no tempo zero para os teores de gordura e de extrato seco. À medida em que se elevou a proporção de soro em relação ao leite, os teores de gordura e de extrato seco diminuíram. O teor de proteína também diminuiu à medida em que se aumentou o teor de soro nas bebidas lácteas, embora a diferença não tenha sido tão acentuada quanto as observadas para os teores de gordura e de extrato seco. em relação à lactose, não se constatou diferença entre os tratamentos. Os teores de soro não influenciaram o índice de proteólise das bebidas lácteas. Verificou-se todavia que as bebidas elaboradas com a cultura probiótica ABY-1 apresentaram valores superiores para proteólise quando comparadas às bebidas elaboradas com as culturas YC-180. As bebidas lácteas elaboradas com 30% de soro apresentaram maiores valores para viscosidade. As bebidas elaboradas com a cultura YC-180 apresentaram valores superiores para viscosidade durante o período de armazenamento.

Some experiments in Physics teaching have an amazing effect among the students, that is, generally be characterized by counteracting the initial expectations of students. This characteristic may contribute to the emergence of learning situations extremely promising. However, the privilege, by the teacher, the description of certain results shortens the involvement that the student could establish on teaching situations favor a more careful observation that can be done. We discuss in this paper, the that surprise may be manifested in the student on an experimental demonstration and its ability to mobilize the interest and curiosity of this student. We intend to observe the pedagogic value that represents the amazing effect such in situations of teaching and learning, particularly for the Teaching of Physics, as well as the possibilities for educational approaches.Through an extensive analysis of several authors who address about experimental learning activities, Epistemology of Science and Education, we found some results that lead us to understand some of the possibilities that the surprise element can propose. We describe a demonstration activity that we consider amazingly from our point of view and that was realized in a regular classroom in a of Rio Claro Public High School in the year of 2011

Dentre as várias instituições das quais o ser humano participa, a escola é uma das mais importantes responsáveis pela construção da representação de quem somos. O educando é o objetivo maior da escola, mas na especificidade da Educação Física que, em geral, é totalmente desvinculada do projeto educacional das escolas, muito pouco tem sido feito, na prática, no sentido de educar os alunos “para a vida. Assim, esse trabalho tem como finalidade implementar aulas de Educação Física que contribuam para a formação do cidadão, e para isto foram elaboradas e desenvolvidas aulas que abordem o conteúdo handebol nas suas três dimensões: conceitual, procedimental e atitudinal. O método utilizado foi o da pesquisa-ação que, de natureza qualitativa, tem como característica o interrelacionamento entre o pesquisador e as pessoas participantes do estudo. As principais dificuldades foram: trabalhar novos conteúdos e a dimensão procedimental, e lidar com o número elevado de alunos. Porém, os momentos de tratar das dimensões conceituais e atitudinais foram muito bem sucedidos.

A remarkable characteristic of the physics subject is the abstraction ability needed during the learning process, which means a non-trivial comprehension and understanding. If the students could not link the themes learned in this subject with observable effects, physics would tend to be a group of mathematical formulas to be memorized. In general, it creates a distance between the student and the subject, and also a prejudice vision of the physics, sometimes for the whole life. Beyond this particular characteristics of physics, the education deals with a source of distraction reinforced by the popularization of mobile access such as cellphones and tablets. The traditional role played by the teacher becomes weak to attract student’s attention. It is necessary that the classes could be planned in such way to achieve three goals: attract student attention, link analytical concepts with real effects and, the most important, gives to the student the ability to use the learned concepts as the key to develop new knowledge. In this work, we present a research based in some experiments used in a CBEF (Brazilian magazine about physical education) and develop an activity consistent with the aims to be reached. To prepare of the experimental activity, we based on Piaget and Vygotsky theories. This work aimed to developed a theoretical research to obtain a didactical activity that deals with the current challenges of the society

This monograph has the inspiring theme using Comic Books in physics education. The Comic Books are objects, which are part of our current daily life, in newspaper, magazines, comics and electronic media, and providing entertainment to the readers. Beyond this property, the ludic nature and linguistics become an interesting material when applied on Education. Our goal was to research an analyze a Comic Book that could be used in a Physics class. The chosen material was Astronauta Magnetar from Danilo Beyruth. With this Comic Book, we perform a short course with students from three High School grade, where the themes of labor were Astrophysics and Electromagnetism. From the results of this short course, we prepared a lot of comments and discussions about the role of Comic Books in a classroom, as an significant instrument for Physics Education
