One tool that has been in evidence, especially among young people, is Facebook. It can be classified as a synchronous communication tool that allows communities of people with similar interests to discuss and exchange experiences in real time, promoting the sharing of information and the creation of collective knowledge, even if they being in different parts of the globe. In this paper we show that Facebook can be used as an educational tool to aid the work done in the classroom and the impact of creating closed groups in online social networking for educational purposes. The survey was conducted with a group of students at a private school in Bauru/SP. We investigated the interaction profile of students with a closed group created on Facebook and through a questionnaire analyzed whether students use virtual environments for personal or educational. The survey reveals students perceptions about relevant aspects and the potential use of this tool as teaching-learning strategy

Electrical conductivity has been proposed as a rapid test to evaluate seed vigor; however, few researches have emphasized methodologies to its use in seeds of medicinal plants, such as chamomile. The objective of the research was to evaluate the electrical conductivity of chamomile seeds affected by different imbibition times and sample size. The evaluations consisted of moisture content, germination and vigor (first count of germination) to seed initial characterization. Then, it was evaluated the electrical conductivity, affected by imbibition time (6, 12, 24 e 48 hours) and seed amount per sample (25, 50, 75, 100). The completely randomized design was used with four replications, arranged as a 4 x 4 factorial. Means were compared by the Tukey test at 5% of probability. It was concluded that the electrical conductivity of chamomile seeds is affected by the number of seeds per sample and imbibition time isolately.
