Introduction

On a thin, long strip of paper, make cuts at opposing ends of the strip at a distance of about 2cm, such that they interlock and look like a fish when folded.

Tools

Parts

    • Handle scissors with care.

  1. Mark and make half-cuts near the ends of the strip on opposite sides The distance of half cuts from the ends should be equal The distance of half cuts from the ends should be equal
    • Mark and make half-cuts near the ends of the strip on opposite sides

    • The distance of half cuts from the ends should be equal

  2. Fold the ends and lock them by passing the cuts through each other Do not crease the paper after folding! Do not crease the paper after folding!
    • Fold the ends and lock them by passing the cuts through each other

    • Do not crease the paper after folding!

  3. Throw the fish up in the air to see it rotate along the horizontal axis as it descends slowly
    • Throw the fish up in the air to see it rotate along the horizontal axis as it descends slowly

    • Inter-lock mechanism too loose

    • Lock mechanism is not equally spaced from the ends

    • Paper creased after completion

    • How long does it take for the paper fish to descend?

    • How many rotations does the fish make per second? How can we measure this?

    • Change the size of the fish: fatter strip, longer strip etc and see if this has an effect on the above readings

    • Make the half-cuts closer and further away from the ends and see if that has an effect.
