Discussion Prompts

Observing

• How did you use your distance values to calculate the size of the crack on the bridge?
• Once you calculated the size of the crack on the bridge, what safety category did it fall into?
• How did you use the data to make your final determination about whether the bridge was safe, at-risk, or dangerous?
• If you were presenting your Bridge Inspection Report to the mayor of Vexville, how would you use it to explain what you learned about the claim?
• How does having a visual display of data, like a table or a bar graph, make it easier to communicate about the data?

Predicting

• What if the location of the crack were different – how might that have affected your rating?
• What if the size of the crack were different – how might a small or medium sized crack affected your rating? 
• What other data might be useful in determining bridge safety? What factors do you think could wear down the surface of a bridge over time? 

Collaborating

• How did your group come to an agreement on the safety rating in the Bridge Inspection Summary? 
• How did you work together to complete the Bridge Inspection Report today? Did you divide the work fairly? Is there anything you would do differently next time? 
• What was the most interesting part of completing the Bridge Inspection Report to you? Why?
