Animal Ear Lab

1. We wanted to figure out if big ears would help you hear further away. So we ran two test one with our normal, ears and the other with enhanced ears. It has been known that larger ears help you hear things further away. Animals that have big ears can hear better than animals with small ears, therefore they can hear another animal coming up on them.

2. The group went outside and we did our testing to see how far we could hear a pin click. We did one with just are regular ears then one with some bigger ears. Most people went further with the enhanced ears. There were a few down fall during this experiment.

4. Did the addition of the larger ear make a difference in the distance at which you were able to hear the pen click? Explain. Yes the enhanced ears made a difference, but your environment that you're plays a big role in how this lab works. The direction on the wind along with the sound of the wind is a major factor. Your surroundings will also effect the way hear.

6. It has small ears to keep the heat from leaving the body.

    They  don't have the capacity to hear far away

    Seals swim better with smaller ears
