Writing a Hypothesis
A
hypothesis is an educated guess about the outcome of an experiment BRFORE YOU
COMPLETE THE EXPERIMENT!!! Good hypotheses are usually “If…then… because”
statements. The “because” is a well
researched reason why you think the way you do.
Look at the following examples of an airplane experiment:
| “I think that Airplane A will fly the farthest.” |
 |
| “I think that Airplane A will fly the farthest because it looks like it would fly the farthest” |  |
| “I think that Airplane A will fly the farthest because it has larger wings and the wings of the airplane create lift which helps the airplane fly” |  |
| “If fly two types of airplanes, then airplane A will fly farthest because airplane A has larger wings and the wings of the airplane create lift which helps the airplane fly. |  |
