Materials Needed

The following is a list of all the materials that are needed to complete the VEX GO Lab. These materials include student facing materials as well as teacher facilitation materials. It is recommended that you assign two students to each VEX GO Kit.

In some Labs, links to teaching resources in a slideshow format have been included. These slides can help provide context and inspiration for your students. Teachers will be guided in how to implement the slides with suggestions throughout the lab. All slides are editable, and can be projected for students or used as a teacher resource. To edit the Google Slides, make a copy into your personal Drive and edit as needed.

Other editable documents have been included to assist in implementing the Labs in a small group format. Print the worksheets as is or copy and edit those documents to suit the needs of your classroom. Example Data Collection sheet setups have been included for certain experiments as well as the original blank copy. While they offer suggestions for setup, these documents are all editable to best suit your classroom and the needs of your students.

Begin the lab by engaging with the students.

  1. Hook

    Students will compare manual movements versus moving things with motors. They will be asked if they get tired of doing something repeatedly. What if they had to hold a book in the air all day?

  2. Leading Question

    How can motors make the Robot Arm more useful?

  3. Build Motorized Robot Arm


Allow students to explore the concepts introduced.

Part 1

Students will move disks using the motors and switches on the Motorized Robot Arm build. They will break down the steps to move one disk to another location and write the step-by-step instructions for another group to follow.

Mid-Play Break

Ask students if they think their directions will be easy to follow for another group. Did they find it easy or hard to write directions? Why?

Part 2

Students will swap directions with another group. As they follow the directions of the other group, students will identify problems in the steps. After identifying the problems in the directions, students will be asked to edit the other group’s directions and try again.


Allow students to discuss and display their learning.
