Building on the scientific and investigative knowledge that students acquire over the years, this program delves deeper into the theory of "science as inquiry". This program helps students recognize the intricate relationship between explanation and evidence through engaging examples. Students trace the path of scientific inquiry--guided by knowledge, observations, ideas and questions--as they combine scientific reasoning and critical thinking. A fun, hands-on activity is included to further demonstrate these concepts. This title correlates to the National Science Education Standards for Science as Inquiry--the necessary ability to understand and do scientific inquiry. A teacher's guide is included. (YDS)
