Discussion Prompts

Observing

• Can you explain what your graph shows about the bottom of the bridge?
• Do you think there is a crack in the bridge? Why or why not? 
• Based on the data you've analyzed so far, do you think the bridge is safe, at risk, or dangerous? Why? What other information do we need to help us make a decision?

Predicting

• What information do you want to find out next to help you complete the inspection? What questions do you have? Is there anything in the Bridge Safety Criteria that we do not know yet? 
• What if a different number of data points were in the Print Console? How would having more or less data affect the results?
• If you were to run the VEXcode project on a different bridge, how could you use the data it printed to tell if the bridge had a crack? 

Collaborating

• How did your group take turns to graph and record the data? 
• What is one problem your group had to work together to solve today? What problem solving strategy did you use?
• What is something that worked really well for your group that you want to do again? What is something you think would help your group work together better next time?
