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 to collect and record data using the Eye Sensor.
How to make a visual representation of collected data.
How to interpret Eye Sensor data to support or disprove a claim.

Students will make meaning of

Analyzing sensor data to determine meaning, like the hue value of a detected object.
Identifying that data is a tool that can be used to test a hypothesis.
Comparing collected data to established criteria to determine whether a claim is supported or refuted.

Students will be skilled at

Opening and running a VEXcode GO project.
Viewing printed sensor data from a project in the VEXcode GO Print Console.
Collecting data about the condition of the bottom of a bridge with the Eye Sensor.
Using the hue values reported by the Eye Sensor to determine the location of cracks on the bottom of a bridge.
Recording and displaying data about the location of cracks on the bottom of a bridge in a Bridge Inspection Report.

Students will know

That data can be collected and used to support or refute a claim.
That data can be compared to given criteria to make a determination.
That data from a project can be printed to the Print Console in VEXcode GO.

Objective(s)

Objective

Students will use the Code Base with the Eye Sensor to collect data about the bottom of a bridge, view the data in the Print Console, and identify whether or not the data indicates a crack on the bridge.
Students will graph and record the data from the Print Console in order to determine if there is a crack on the bridge.

Activity

Students will open and run a VEXcode GO project for the Code Base to drive underneath a bridge, and print data at incremental points about the hue value and distance travelled beneath the bridge using the Eye Sensor. They will discuss the data that was printed in the project, and determine the data suggests there is a crack in the bridge.
Students will graph each data point from the Print Console in their Bridge Inspection Report. They will then identify the data points that correspond to a crack in the bridge, and record them in a data table.

Assessment

During the Mid-Play Break, students will share what they noticed about the data that was printed in the Console. They should be able to explain that the hue values in the data indicate there is a crack present on the bridge.
Students' graphed and recorded data should realistically represent what could actually be reported by the Eye Sensor. Students' Bridge Inspection Reports should also display accurate data collection.

Connections to Standards

Showcase Standards

Computer Science Teachers Association (CSTA)

1B-DA-06: Organize and present collected data visually to highlight relationships and support a claim.

How Standard is Achieved: In the Engage section, students learn about criteria for safe, at-risk and dangerous bridges, and are given a claim that a bridge has a crack and may be unsafe. Then, in Play Part 1, they open and run a VEXcode GO project to use the Eye Sensor to print distance and hue value data about the bottom of the bridge. In Play Part 2, they graph and record data in their Bridge Inspection Report, and determine if there is a crack in the bridge.

Showcase Standards

Computer Science Teacher Association (CSTA)

1B-DA-07: Use data to highlight or propose cause-and-effect relationships, predict outcomes, or communicate an idea.

How Standard is Achieved: During the Engage section, students learn about a claim that a bridge has a crack, as well as the criteria for safe, at-risk and dangerous bridges. After collecting data using the Eye Sensor in Play Part 1, they use the data in comparison with the criteria, to determine if the claim about the bridge is true. They communicate the results of their analysis by creating a Bridge Inspection Report during the Play section of the Lab, sharing with their classmates in the Share section of the Lab.
