InquiryQuestioning
and Investigating
Investigate an answerable question through valid experimental techniques. Conclusions are based on evidence and are repeatable
8th Grade
Preconceptions :Three – Two - One
• Three Inquiry Standards that will be answered as a two point questions
• Two Inquiry standards that will be only Multiple Choice
• One inquiry standard that will not be tested
Inquiry?
• Ask Questions• Plan Investigations• Collect Data• Repeat for reliability• Understand Models• Emphasize Evidence• Communicate results• Be honest

How does the model describe a scientific event?
How is the model accurate?How is the model inaccurate?
Example
• What real object is this a model showing?
• What is accurate about the model
• What is inaccurate about the model?
