  1. 1

    Micah began a new project at the science tub.

  2. 2

    The goal was to build a foil boat that carried marbles.

  3. 3

    Before building, Micah sketched a plan and listed needed materials.

  4. 4

    The first attempt showed a problem: wide boats folded under heavy cargo.

  5. 5

    Micah felt disappointed, but treated the failure as useful evidence.

  6. 6

    Micah invited his friend Suki to examine the design.

  7. 7

    They measured carefully and discussed which part should change first.

  8. 8

    Their revised plan used high sides and evenly spaced marbles.

  9. 9

    They changed only one feature so the test would be fair.

  10. 10

    The second attempt worked better, although it still needed adjustment.

  11. 11

    Micah recorded the result instead of trusting memory.

  12. 12

    A final improvement made the design safer and more reliable.

  13. 13

    The team repeated the test to make sure the success was not luck.

  14. 14

    This time, the project produced a boat that carried thirty marbles.

  15. 15

    Micah labeled the model so others could understand each part.

  16. 16

    Visitors asked thoughtful questions and suggested future experiments.

  17. 17

    Micah discovered that strong projects grow through testing and revision.

  18. 18

    The finished work was useful, but the learning mattered even more.
