Teacher Portal

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.

Engage

Begin the lab by engaging with the students.

  1. Hook

    Let’s talk about some devices and machines in our daily lives, and how they work. Let’s think about our Robot Arms now. We’ve changed from manual to motorized controls, do you think we could control its movement with coding?

  2. Leading Question

    In order to use coding with the Robot Arm, we’d need to add a brain.

  3. Build Code Robot Arm (1-Axis)

Play

Allow students to explore the concepts introduced.

Part 1

Students will code the motors to move first, by coding the Robot Arm to move to each quadrant of the tile (as marked by the green plate) and stop.

Mid-Play Break

So we can move the Robot Arm, but what about the magnet?  What is different about the electromagnet you added from the original magnet?

Part 2

Students will code the Robot Arm to use the electromagnet to pick up and move a disk to another location on the tile.

Share

Allow students to discuss and display their learning.
