The use of computers in childhood education makes it possible for them to acquire knowledge in a fun way through games. This paper describes the experience of implementing the course “Computers for Children”, which is part of a University Extension Program at the School of Dentistry at UNESP - Araraquara. This course is offered to children aged 5-7 years old and it aims, not only, to offer children, via computer, a direct contact with new teaching technologies, but also, to help them develop both their motor and logical thinking abilities through educational games. The children that participated in this course are from the Children’s Center “Casinha de Abelha” at the UNESP -Araraquara and also from the Municipal Recreation and Educational Centers also in Araraquara, SP, Brazil. The software resources used in this course to teach computer skills are the educational games “Coelho Sabido Maternal”, “A Estrela Cintilante” and “Festa dos Dentinhos”. The children’s learning and the level of difficulty in using the computer as a tool were evaluated. It was possible to conclude that the course has been contributing to the digital inclusion of children aged 5-7 years old, in addition to training their visual and audio perception, their motor coordination and memorization, hence developing skills that are essential to the children’s literacy process.

Some organisms disperse energy, associated with the transportation of resource, which is not necessarily food. Stingless bees of Central Amazonia (Melipona flavolineata and M. lateralis) collect clay in banks along streams for nest building. The moisture of the clay varies along the bank, and bees collect clay from specific location, indicating that there is some sort of preference regarding their selection. This study aims at identifying: if larger bees carry more clay; if there is a preference for moisture of substrates; and if bees are less efficient accumulating and transporting clay when it is wet. In order to do so, I measured the size of the bees and of the pellets of clay found in the corbicula. I set up a field experiment to test substrate preferences. The amount of clay transported, increased exponentially in accordance to the size of the bee, and the preferred substrate was the driest clay. The amount and the efficiency of removal of clay were not affected by the moisture of the substrate. Despite the wet clay being denser, it does not reduce the efficiency of exploitation of the resource, but suggests that bees spend more energy to carry the same quantity of wet clay, which may be the underlying mechanism explaining their preference for removing drier clay.
