This document provides guidelines for posters and evaluations for a national children's science congress. It states that Poster 1 should include basic identifying information about the project, members, and school. Poster 2 should include the objectives and methodology. Poster 3 should present data analysis with charts, graphs or photos. Poster 4 should present the results, conclusion, and solutions. It then provides two evaluation sheets that will be used to score the written reports and oral presentations, with criteria such as originality, relevance, understanding, data analysis, and problem solving. Scores from each category will be combined for a total score out of 200.
