Can planes as far when they have weight on them?

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

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

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.

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

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