  EALR 2:   Inquiry  
  Big Idea:   Inquiry (INQ)  
  Core Content:   Planning Investigations                   
  Description:   In prior grades students learned to conduct different kinds of investigations. In grades 4-5 students learn to plan an investigation, which involves first selecting the appropriate kind of investigation to match the question being asked. One type of investigation is a controlled experiment (a "fair test"). Others include systematic observation, field studies, and models and simulations. Students can also collect, display, and interpret data; summarize results; draw conclusions from evidence; and communicate their findings. Students are aware that scientific explanations emphasize evidence, involve logical arguments, and are consistent with scientific principles and theories. Students are also expected to communicate their findings and to critique the investigations of others with respect and intellectual honesty. These capabilities are essential in preparing students for the more extensive and rigorous investigations that they will be planning and conducting in middle school.  
  Content Standard:   4-5 INQC —Investigate— An experiment involves a comparison. For an experiment to be valid and fair, all of the things that can possibly change the outcome of the experiment should be kept the same, if possible.  
 
 
 
Students are expected to:
  • Conduct or critique an experiment, noting when the experiment might not be fair because things that might change the outcome are not kept the same.
