Question: Can planes as far when

they have weight on them?

Hypothesis:

We thought the heavy planes wouldn’t fly as far as the light planes.

Materials:

We used sling-shot planes, pennies, tape, and a tape measure.

Procedure: 1) We flew the planes 3 times

with-out pennies.2) We marked where they

landed with tape.3) We added 8 pennies and

flew them again. 4) We marked where they

landed.5) We measured using a tape

measure.6) We graphed the median.

Results :We both found that the planes with the pennies didn’t fly as far.

Conclusion:

Heavier planes don’t fly as far as light planes.
