Lab: Find Your Natural Walking Pace
Duration: Approximately 40 minutes
Students determine their rate of speed while walking at a natural pace (not a race). They collect data in a table, conducting multiple trials and controlling the variables, and then calculate an average and share their findings.
Students use proportional relationships (e.g., speed as the ratio of distance traveled to time taken) among different types of quantities to provide information about the magnitude of properties and processes.
Students understand the concept of a ratio and use ratio language to describe a ratio relationship between two quantities.
Students understand the concept of a unit rate and use rate language in the context of a ratio relationship.
- Do the lab yourself before trying it with students.
- Some students may need a language scaffold to share their data (see example sentence frames below).
- If you have students with mobility issues that would inhibit participation, devise some alternative testing criteria (besides walking) that all students can perform, and use it for all students (rather than singling out those unable to walk).
- a hallway or outdoor space where students can mark off a 20-meter walking course
- a measuring tape for measuring the course
- some removable tape, chalk, or cones to mark the course at the various lengths
- stopwatches for timing (students may have apps on their phones to use)
- Review with your students all your school's safety protocols when doing labs.
- Emphasize that this is a walking—not a running—race.
