  • How would you describe the actions of the Code Base when the Eye Sensor detected a Red Disk?
  • How did the [If then] block use the data from the Eye Sensor to sort your Red Disk to the right location? 
  • What block(s) control the Eye Sensor in our projects? 
  • What did you need to figure out in Play Part 2 to drive to collect then sort the Disk? What strategies did your group use to solve the challenge? 


  • What do you think would happen if your Code Base picked up a Blue Disk? Would your project still work the same way? Why not?  
  • How do you think you could build on this project to sort more Disks with different colors? 
  • Do you think an Eye Sensor would be a useful tool on a real Mars rover? Why or why not?


  • What is one way that you were a problem solver in your group to help collect the Disk from the new location? 
  • If a new student joined your group, how would you explain how to code the Eye Sensor on the Code Base to sort a Disk based on its color? 
  • How did your group take turns during the Lab? What would you like to work on in your group or change for next time?
