Investigating Crayfish describes a backyard crayfish investigation carried out by two curious kids. Hannah and Manny decide to explore a nearby creek and soon discover many crayfish live there. Guided by HannahÌs mother, a scientist and teacher, the two children create their own scientific investigation to answer a question about crayfish. In an engaging and informative way, the book models the whole scientific processÛselecting a question, planning an investigation, making hypotheses, recording data, explaining results, and communicating those results to a wider community. The process described in the book foreshadows a parallel process that will take place in the classroom as students prepare for their own model pond investigations.
