PLAN AND CONDUCT A SIMPLE INVESTIGATION.In the earliest years, investigations are largely based on systematic observations. As students develop, they may design and conduct simple experiments to answer questions. The idea of a fair test is possible for many students to consider by fourth grade.
COMMUNICATE INVESTIGATIONS AND EXPLANATIONS.Students should begin developing the abilities to communicate, critique, and analyze their work and the work of other students. This communication might be spoken or drawn as well as written.
