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

Ecotower Observation #3 4/8/2011

1. Animals:
        -Worms: We burried three worms in the soil in our ecotower so we don't know if they are alive or not.
        -Snails: The snails we had died.
        -Crickets: All of our crickets are dead.
        -Beta Fish: The fish we had is still living.

2.We think that the algae is keeping the fish alive. The animals died at the top died from not enough of oxygen. The worms are still unknown because we can't see them The snails died in the water.

3. Plants:
       -Beans Plant: It grew but is starting to die.
       -Algae: It's turning a brown color.
       -Other Plants: They are beginning to die.

4. The plants are starting to die because they aren't getting anough carbon dioxide. The algae is turning brown from lack of oxygen

5. The water is getting yellower. It has particles floating around it. The algae is sinking.

7. I dont't think the fish will die until the algae dies completely
