### Description

Students are asked to use proportional reasoning and scale to design a racecourse for the Speedbot.

### Key Concepts

• Mathematical Reasoning

• Proportional Reasoning

• Iterative Design

### Objectives

• Create a racecourse by planning with scaled drawings.

• Analyze relationships between scaled measurements.

• Practice converting units.

• Understand the use of scales and proportional reasoning.

### Materials needed

• 1 or more VEX V5 Classroom Starter Kits

• Roll of Tape

• Meter Stick or Ruler

• Calculator

• Engineering Notebook

• Stopwatch

• Multiple boxes

• 3-Ring Binders

### Facilitation Notes

• Ensure all required parts for the build are available prior to starting this STEM Lab.

• Although the V5 Robot Brain is included in the build of the VEX V5 Speedbot, no programming is required.

• Make sure that there is ample space in the classroom to measure out and tape the field area for the racecourse that will be used.

• Providing a set space to create a racecourse within can help expedite initial decisions for the design area.

• An engineering notebook can be as simple as lined paper within a folder or binder. The notebook shown is a more sophisticated example that is available through VEX Robotics.

• During the iterative design process prior to the challenge, teams should be testing the accuracy of their measurements and mathematical conversions.

• The approximate pacing of each section of the Stem Lab is as follows: Seek- 125 minutes, Play- 85 minutes, Apply- 15 minutes, Rethink- 45 minutes, Know- 5 minutes.

Math

• Add other items to the physical racecourse, based on scale. Some items could include, stands, a press box, concession stand, trees, benches, etc.

• Draw a map of the school campus or other well-know location in the school community with the correct scale.

Social Studies

• Look at various maps to compare the scales used. Have the students create their own set of questions and then trade with each other to solve.

• Research how cartographers use technology to help create more accurate maps.
