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

    In the last Lab, we used the Electromagnet on our Code Base. Our robot also has an Eye Sensor on it, too! How do you think we could use the Eye Sensor with the Electromagnet to make our Code Base do more things with a Disk?

  2. Leading Question

    How can we code the Code Base to make a decision based on the color detected by the Eye Sensor?

  3. Build Code Base - Eye + Electromagnet

Play

Allow students to explore the concepts introduced.

Part 1

Students will build on what they learned from Lab 1, adding an [If then] block and a <Detects color> block, to use the Eye Sensor to report the color of the Disk collected by the Electromagnet to make a decision and drive it to the sorting area.

Mid-Play Break

Come together to check in on students' progress and talk about what the Code Base is doing in their projects. How does the Eye Sensor work in our project? What block(s) control the Eye Sensor? How did you make the Electromagnet work with the Eye Sensor in your project? Then, segue to Play Part 2 by asking, what if we change the location of the Disks or the sorting areas? Will this project still work? Why or Why not? What parameters would you change?

Part 2

Students will work in their groups to iterate on their projects from Play Part 1, to complete the challenge of collecting the Red Disk from a different location and delivering it to a different sorting area, using Eye Sensor data.

Share

Allow students to discuss and display their learning.
