Getting the Students Ready to Build
In order to analyze our data to determine if the claim about the bridge is true, we will need to use the data in the Bridge Inspection Reports that we began in the previous Lab.
Facilitate the Build
- InstructInstruct students that they are going to be continuing to work with the data they collected in Lab 2. Students do not need to construct a new build for this Lab.
-
DistributeDistribute
each group's Bridge Inspection Report, making sure each group has a complete set of data from running the Printing Data VEXcode GO project from Lab 2.
- Each group's Bridge Inspection Report should have the Graph the Data and Data Points of the Crack section filled out.
-
FacilitateFacilitate
students' gathering data using the project from Lab 2, if they do not have a completed their graph in their Bridge Inspection Report.
You may want to have a setup from Play Part 1 of Lab 2 ready for students to use. You will need a Code Base with Eye Sensor facing up, a bridge setup, and the Printing Data project open in VEXcode GO. Refer to Lab 2 for more information about how to run the project and record the data.
Lab 2 Bridge Setup with Code Base - OfferOffer help as needed to ensure that all students have their started Bridge Inspection Reports and are ready to continue completing them.

Teacher Troubleshooting
- When calculating the approximate size of the crack on the bridge, students may get slightly different results, which is expected. However, if a students' calculation falls well outside of the dangerous range (greater than 40mm), students should check their math and try again.
Facilitation Strategies
- You may want to provide some sample graphs to use with students for whole group practice with calculating the size of the bridge crack before they use their own data to do so, depending on students' level of subtraction experience.
- Have students take turns reading and recording data on the fourth page of their Bridge Inspection Report, so all students have an opportunity to engage with the data.
