KiC-2 (The catapult exercise) Get the materials here (see below)

Once you run the KiC-1 exercise to introduce the scientific, 4-step Improvement Kata pattern, your learners can apply that framework to a variety of content and activity. That's good practice!


However, the KiC-1 exercise does take two non-scientific shortcuts, which become teaching opportunities in the KiC-2 exercise:


  • Participants could change more than one variable at a time.

  • Participants collected only 1 data point before designing the next experiment.

The KiC-2 exercise addresses these issues and prepares students to apply the Improvement Kata pattern in projects and activities that involve data. Emphasis is placed on practice using run charts to collect, depict, analyze and interpret data as the learner strives for a goal. Data literacy is essential for many jobs and careers.


KiC-2 is a group exercise, with the educator acting as the coach and scribe. As with the KiC-1 exercise, everything you need to run KiC-2 is shown below. Instructions are at the start of the PowerPoint file, so begin by downloading and reviewing that. Run the exercise as designed once or twice, then adapt it as you like.

Order one "Xpult" catapult

The Xpult costs US$39.- and is available online from and eBay.


Because KiC-2 is a group exercise, you only need one Xpult for the exercise.

Use 2 clamps to hold your Xpult. More stable.

After the KiC-2 exercise, find opportunities for your learners to practice making run charts with target condition lines. What information would the learner like to track & plot? How much time is spent on homework each day? How long you brush your teeth? The possibilities are endless, and doing this helps learners think more scientifically.
