  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 INQF —Models— A scientific model is a simplified representation of an object, event, system, or process created to understand some aspect of the natural world. When learning from a model, it is important to realize that the model is not exactly the same as the thing being modeled.  
Students are expected to:
  • Create a simple model to represent an event, system, or process.
  • Use the model to learn something about the event, system, or process.
  • Explain how the model is similar to and different from the thing being modeled.
