## Reflection: Discourse and Questioning Density Column Lab - Section 5: Density Column Lab: Making Predictions

Group discourse can be challenging!  Providing students with sentence starters can be an effective strategy for aiding students in group discussions.  In this lesson, I ask students who are offering predictions to start with, "The __________ will fall next.  The data that supports this idea is...".

In addition, I ask students to ask any student that does not back up a prediction with data to ask, "What data supports that idea?".  Often, students just don't know how to start.  By providing them with something to go on, there are many students that join in the conversation that previously wouldn't have!
