- What are some ways of determining whether or not a movement is precise?
- How might you graph values to represent real-life movement?
Build a smart yoga ring.
- Done! I've built my yoga ring.

Practice one yoga move.
- I'm performing my first move with my yoga ring.
- I can see the data on the line graph.
- I can match the data on the red line.

Practice another yoga move.
- I change the plotted value from pitch to roll.
- I'm doing my second move with my yoga ring.
- I can match the new data on the red line.

Follow the graph.
- I've adjusted my program to graph 2 values.
- I've tried to follow the graph.
- I’ve answered these questions:
- How precise were my movements?
- Why was that?

How would you summarise your experiment?
- In your own words, explain pitch, roll and yaw.
- How much have you tested the precision of your yoga ring? What did you do well?
Brilliant!
