What a learner can do afterwards

  • Test two designs that address the same problem and collect data on their performance
  • Compare the results, identifying strengths and weaknesses of each design
  • Use data as evidence to recommend which design works better and suggest improvements

The lesson

Sometimes two people build different designs for the same job. You can test both and use the data to compare them.

Plane A4Plane B7
Plane A flew 4 meters. Plane B flew 7 meters.
Try it together

Mia tests two boat designs. Boat A holds 5 coins. Boat B holds 9 coins. Mia looks at the data and picks Boat B.

Good to know

No design is perfect. One design might be strong. Another might be light or fast. Data helps you pick the best one.

Test both designs, compare the data, then pick the best one.
