Fighting a Dragon with a Cannonball!

About to release marble from 4 cm

Yesterday we fought dragons with cannonballs! The children built ramps using a ruler and a Styrofoam cup. They placed a paper dragon in front of the ruler, and started their "cannonball" at differing spots on the ruler to see the results. They placed the cannonball at 4cm,8cm, 12cm, 16cm, 20cm, 24cm, and 28cm. The distance the dragon was pushed was documented, averaged, then graphed.
