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

## Goals

Students will apply

• How two forces on the Steering Super Car,  from two motors,  allows it to turn.

Students will make meaning of

• Applying data and experience to predict an object’s continued motion, change in motion, or stability.
• Using basic commands to control robotic movement (forward, reverse, left, right).

Students will be skilled at

• How to make predictions and then test them.
• How to recognize patterns in changes of movement.

Students will know

• How to predict and then test the Super Car’s change in motion with two motors.
• How to use unbalanced forces to make the Super Car move.

## Objective(s)

### Objective

1. Identify how the combined forces from two motors allow the Steering Super Car to turn.
2. Apply basic robotic movement (forward, reverse, left, right) in order to steer the Steering Super Car.
3. Predict an object’s continued motion, change in motion, or stability.

### Activity

1. Groups will pair up to combine their Motorized Super Cars together to create a Steering Super Car. They will then experiment with 9 permutations of motor movement to guide the car: forward, off, reverse for each motor.
2. Students will explore how balanced and unbalanced forces are used to steer their car.  Groups will experiment with the Switches: turning them on in succession or in a staggered sequence. Groups should recognize that multiple forces are needed in order for the car to turn.
3. Students will control the Switches for the motors in order to turn and navigate around obstacles.

### Assessment

1. Students will describe their predictions of movement (in drawing or word format), test it, and then record their observations in the 9 test trials.
2. Facilitate using the switches to create balanced and unbalanced forces that will cause the car to turn.
3. Students will anticipate and practice turning with dual motors to succeed in the Driver Test Course. Combined groups will be able to successfully navigate the obstacles in the Driver Test Course.
