Implementing VEX GO STEM Labs

STEM Labs are designed to be the online teacher’s manual for VEX GO. Like a printed teacher’s manual, the teacher-facing content of the STEM Labs provides all of the resources, materials, and information needed to be able to plan, teach, and assess with VEX GO. The Lab Image Slideshows are the student-facing companion to this material. For more detailed information about how to implement a STEM Lab in your classroom, see the Implementing VEX GO STEM Labs article.

Goals and Standards


Students will apply

  • How to create and start a VEXcode GO project that makes the Code Base robot move forward, backward, and turn.
  • Drivetrain blocks in the correct sequence to create a project to solve a challenge.

Students will make meaning of

  • How to solve a challenge with the Code Base robot and VEXcode GO.

Students will be skilled at

  • Using build instructions to build the Code Base - LED Bumper Top.
  • Connecting a Brain to a tablet or computer in VEXcode GO.
  • Saving and naming projects in VEXcode GO.
  • Adding VEXcode GO blocks to a project.
  • Sequencing blocks in a project.
  • Using Drivetrain blocks in a project to have the Code Base robot drive to a specific location.
  • Changing parameters in VEXcode blocks.
  • Starting a project in VEXcode GO.

Students will know

  • How scientists learn about Mars with rovers, which collect samples of rock and soil for a possible return to Earth to be studied.
  • How to use VEXcode GO with the Code Base robot to solve a challenge.



  1. Students will develop a VEXcode GO project that orders behaviors in a sequence to complete a challenge.
  2. Students will communicate behaviors, through words and gestures, that the Code Base robot will need to complete in order to accomplish a task.


  1. In Play Part 1, students will create and test a VEXcode GO project that has the Code Base robot drive to collect a sample. In Play Part 2, they will add to their project to have the robot return to the base (starting position).
  2. Students will describe how the Code Base robot moves forward, backward, and turns in order to drive to collect a sample as they build their projects in Play Part 1. In Play Part 2, students will describe how to move the robot to return to the base as they add to their projects.


  1. Students will create a project that successfully sequences Drivetrain blocks to move the Code Base Robot to collect a Mars soil sample in Play Part 1. In Play Part 2, students will successfully add to their projects to have the robot return to the base —or starting position.  In Share, students can demonstrate their projects and discuss how they ordered the blocks in the project to complete the challenge.
  2. In the Mid-Play Break, students will discuss how they ordered the blocks in their project. In the Share section, students act out the projects using gestures to show how the Code Base robot moved.
