Implementing VEX 123 STEM Labs

STEM Labs are designed to be the online teacher’s manual for VEX 123. 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 123. 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 123 STEM Labs article.

Goals and Standards

Goals

Students will apply

  • Using the [Drive until] block in a VEXcode 123 project that will continually check a condition and will not move to the next block until the condition is met.

Students will make meaning of

  • How to code the 123 Robot to solve a challenge, such as driving until an object is detected.

Students will be skilled at

  • Waking the 123 Robot.
  • Connecting the 123 Robot to VEXcode 123.
  • Adding VEXcode 123 blocks to a project.
  • Sequencing blocks in a project.
  • Using the [Drive until] block in a project to have the 123 Robot drive until an object is detected.
  • Changing parameters in VEXcode blocks.
  • Starting a project in VEXcode 123.
  • Saving a VEXcode 123 project.

Students will know

  • How the Eye Sensor on the 123 Robot can be used to detect objects.
  • That the [Drive until] block in VEXcode 123 works with the Eye Sensor to drive until the Eye Sensor detects an object, and then stops.
  • How to use the [Drive until] block in a project to have the 123 Robot drive until it detects an object.

Objective(s)

Objective

  1. Students will develop a VEXcode 123 project using the [Drive until] block to complete a challenge.
  2. Students will identify that the Eye Sensor on the front of the 123 Robot can detect objects in its field of view.
  3. Students will communicate behaviors, through words and gestures, that the 123 Robot will need to complete in order to accomplish a task.

Activity

  1. In Play Part 1, students will create a project using the [Drive until] block for the 123 Robot to drive until the Eye Sensor detects an object.
  2. In Engage, students will identify the Eye Sensor on the front of the 123 Robot and how that sensor is used to detect when an object is present. They will connect the Eye Sensor to the [Drive until] block and how that block works in a project in a guided demonstration.
  3. In Play Part 1, students will describe how the 123 Robot moves when the [Drive until] block is used.

Assessment

  1. In Play Part 2, students will add to their projects with the [Drive until] block so the 123 Robot makes a sound or the indicator light on the robot glows a color after an object is detected by the Eye Sensor.
  2. In the Play section, the students will identify the location of the Eye Sensor on the front of the 123 Robot and place the robot so the obstacle is in the field of view of the Eye Sensor.
  3. In Play Part 2, students will describe how the additional block added affects the behaviors of the 123 Robot.
