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 data can be used to make accurate predictions.
• How to observe cause and effect relationships.

Students will make meaning of

• How an unbalanced force, such as gravity on an inclined plane, causes an object to move.
• Using data to highlight or propose cause-and-effect relationships.

Students will be skilled at

• How to test, measure, and record data.
• Changing the height of the Inclined Plane.

Students will know

• How to conduct an investigation to provide evidence of the effects of balanced and unbalanced forces on the motion of an object.

## Objective(s)

### Objective

1. Students will identify a cause and effect relationship between gravitational force and the movement of an object on an inclined plane.
2. Students will conduct an investigation to provide evidence of the cause and effect relationship of balanced and unbalanced forces on the motion of an object.

### Activity

1. Students will observe the cause and effect relationship of the height of the Inclined Plane and distance a Blue Wheel will travel when rolled down the Inclined Plane. Through testing in Play Part 1 and 2, they will determine that the height of the Inclined Plane affects the force of gravity on the wheel, which affects the distance traveled of a rolling wheel.
2. Students will make predictions then test how far a wheel travels after rolling down an Inclined Plane in Play Part 1. In Mid-Play Break, students will discuss the results from Play Part 1, reiterate the purpose for the investigation, and discuss how to improve predictions. In Play Part 2, students will make predictions for two additional heights of the Inclined Plane and then test and record those predictions using their Data Collection Sheet

### Assessment

1. Students will recognize that the different heights of an Inclined Plane affect the gravitational force on an object. Students will share their learning in the Data Collection Sheet and in discussions during Mid-Play Break and Share sections.
2. In Play Part 2, students will analyze data collected in the first trial test to make more accurate predictions for two additional tests. Students will be able to see an improvement in their predictions as documented on their Data Collection Sheet.
