Lavoisier Reaction

Posted By on September 23, 2015

Law of Lavoisier. Didactic game: To revise the contents and to really confirm if lessons had been of great value for the group, since our evaluation is a process continues. Hunting words DESCRIPTION OF the DIDACTIC GAME. HUNTING? WORDS WAY TO PLAY will be formed 05 (five) groups where the team that to find first the reply in the hunting words delivers to each participant will signal for the professor who made the question and will gain point. Each question valley 5 points and the last question will be valid 15 points. The team that more to make points will be the winner. QUESTIONS 1 – Scientist who discovered the law of the conservation of masses R: Lavoisier 2 – Scientist who discovered the law of constant ratios R: Proust 3-Scientist that elaborated an atomic theory, whose basic postulate was that the substance would have to be formed by extremely small entities, called atoms R: Given 6-Name atomic mass unit when the atom number of each element is the same on both sides of the equation.

R: Balancing. 7 – Type of reaction that liberates heat R: Exotrmica 8? Type of reaction that absorbs heat. R: endothermic 9 – Type of chemical reaction that occurs in hydro-carbons R: combustion 10 – Gas formed in a reaction of complete combustion. R: Carbon dioxide 11 – Gas formed in a reaction of incomplete combustion. Carbon monoxide 12 – Combustible less pollutant. R: 13-Part alcohol of the chemistry that studies and analyzes the quantitative relations between the elements that if combine to form a composed substance. R: Estequiometria? Conceptual map: Systematization of the boarded contents; Developing abilities of: to observe, to measure, to analyze, to conclude, amongst others. DESCRIPTION OF the CONCEPTUAL MAP will be demonstrated to a graphical representation of all boarded content of schematized form and a debate to relate the reason between on concepts that had taken the formation of the conceptual map.

COMMENT: The evaluations will occur adopting it law of Lines of direction and Bases of Educao (LDB), approved em1996, where it determines that this is continued cumulative and that the qualitative aspects prevail on the quantitative one. Thus, the results gotten for the students throughout the course must more be valued than the note of the final test. The resources: ) Human beings? professors and pupils of average education. b) Materials? chalk picture; chalk/eraser; didactic video; official paper; steel straw or wool, grains of rice (or chalk pieces), palitos of match; wire c) Equipment? computer and accessories; retroprojetor; calculator. IV? FINAL CONSIDERAES the development of this project demonstrated that estequiometria is possible to develop the chemical content, leaving of the social subject: atmospheric pollution motivating to the learning in the learning to multidiscipline of science, acquiring knowledge them of its paper in the society and promoting a learning significant.
