ResultsResults

Our results showed distances and average Our results showed distances and average distances the round and oblong balloons distances the round and oblong balloons travelled. The recordings show trial distances of travelled. The recordings show trial distances of the round balloon to be 173in., 168in., 175in., the round balloon to be 173in., 168in., 175in., 165in., and 190in.The oblong balloons 165in., and 190in.The oblong balloons travelled156in., 223in., 211in., 203in., and travelled156in., 223in., 211in., 203in., and 228in.The data shows the average distance 228in.The data shows the average distance travelled by the round balloon was 174in. And the travelled by the round balloon was 174in. And the oblong balloons is 204in. The oblong balloons oblong balloons is 204in. The oblong balloons travelled 30 inches farther than the round balloon travelled 30 inches farther than the round balloon on average.on average.

ConclusionConclusion

In conclusion our hypothesis was correct In conclusion our hypothesis was correct because the average distance for the oblong because the average distance for the oblong balloon was 30 inches more than the round balloon was 30 inches more than the round balloon. We believe that in the real world some balloon. We believe that in the real world some things are more aerodynamic than others. Birds things are more aerodynamic than others. Birds and alligators travel farther faster because of their and alligators travel farther faster because of their shape. Birds have less wind resistances. Alligators shape. Birds have less wind resistances. Alligators have less water resistance. Oblong balloons have have less water resistance. Oblong balloons have less resistance than the round ones which make less resistance than the round ones which make them travel farther. We think more trials would give them travel farther. We think more trials would give the same results, but we should try to be surethe same results, but we should try to be sure . .
