This study was conducted in partnership with the Extension Project in Education Environmentally Semente Viva and it is an assessment of the environmental education methodology applied by the Group in 2014, at the Municipal School Sylvio de Araújo, in Rio Claro- SP. The implemented methodology was named Programa Eco Escolas- Semente Viva and it was based on the use of certain bases of the Eco-Schools program, created by the FEE (Foundation for Environmental Education), with some adjustments in accordance with the goals of the Group. The study followed the participatory research method, and the data collection gave up through participant observation, literature and documentary. The chapters present the description and analysis of the events that represent the implementation process of the Programa Eco Escolas- Semente Viva. The meetings with the community and environmental education activities with children from 1st to 4th year are described in detail, and is given regarding the analysis of situations, from the point of view of one of the members of the Semente Viva Group

This research evaluated corn grains with flint and dent texture (ensiled high-moisture or dried), submitted to grinding degrees, using the in situ ruminal degradation technique. Three rumen canulated adult sheeps were used in a complete randomized design, using a factorial outline 2 x 2 x 3, with two corn hybrids (flint and dent texture), two conservation methods (ensiled high-moisture and dry) and three grinding degress (whole, coarsely and finely ground, corresponding to the sieve of 12; 10 and 8 mm). Starch soluble fraction (A) of the dent hybrid ensiled corn grains was greater comparing to the dry materials and in both conservation forms this fraction was reduced in the flint texture hybrid, while the insoluble fraction potentially degradable (B) the opposite occurred. The degradation potential was higher in grains ensiled in two textures. The ensiled allowed more starch effective degradation in relation to dry grain in two textures and the grains dent texture hybrid also increased such degradation in both conservation methods. The dent texture and the ensiled high-moisture grains proved the best option considering the starch degradability. Regardless of the conservation forms, the grains of corn hybrid flint texture should be finely ground, for providing higher ruminal degradation, while for the dent texture hybrid, the coarsely and whole grinding are the most suitable for ensiled and dry grain, respectively.
