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?

Model Guide

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?
