Data Detectives: Bridge Challenge

3 Labs

Learn about what data is, what a sensor is, and how sensors report data, so that you can learn to collect and use data to make and support claims about authentic problems. Become a bridge inspector, and use the Eye Sensor on the Code Base to help you assess bridge safety with sensor data.

Lab 1

Understanding Data

Total Time: 40 minutes

Become a bridge inspector and learn to collect and use Eye Sensor data to make and support claims about bridge safety. Note: This is an advanced STEM Lab.

What is the Eye Sensor and what data does it report?

Build: Code Base - Eye Down

Lab 2

Collecting Data

Total Time: 40 minutes

Use the Eye Sensor on the Code Base to collect data about a crack on the bottom of a bridge, and graph the data on the Bridge Inspection Report.

How can I collect data with the sensor?

Build: Code Base - Eye Down

Lab 3

Analyzing Data

Total Time: 40 minutes

Analyze bridge data in order to make a hypothesis about which bridge is unsafe and needs to be inspected.

How can I use data to help solve an authentic problem?
