Easy Science Fair Project
By S. Goodman

An easy project that I did with a third grade class follows:
Hypothesis: Bigger Ears allow you to hear better.
First pose the question to your class- if they think they'll hear better with bigger ears.

Procedure:
Have students listen to 3 or more sounds with "big ears" and regular ears. TO make big ears, have the students cup their hands (a big c shape) behind their ears. Have then listen to a sound- then have them take their hands of and listen to the same sound again with regular ears. Repeat with different sounds
Collect Data:
Make a little chart for each child to record which they

hear better with- big ears or regular (or no difference)
Tally the class data and graph on a chart.

This is pretty simple w/o getting too technical
Good luck
We won a first place ribbon for this one!
