Does Music Affect A Caterpillar's Growth?  If So, What Kind?

Jennifer M

For this experiment, we rounded up caterpillars, and had them listen to three kinds of music, Jewel-Soft, Offspring-Loud, and Dixie Chicks-Soft and Loud. The purpose was to find out if caterpillars would grow differently because of  the music they listened to.  The other living needs like food remained the same. As a result one set of larva turned into beautiful Monarchs. This group listened to Jewel. I believe our group made two errors, 1. we didn't keep up with our journals, those were assigned to us, and 2. We should have had one group listen to no music as our control.  I learned to use time wisely and be a better observer.


How Fast Does A Caterpillar Move?

Andy U

I tested to see how fast a monarch caterpillar could find its food.  The purpose was to see that if a caterpillar fell off its milkweed plant, could it get back on the plant in time.  I found that they could get back on in time. All four caterpillars that were tested could go two inches in under one minute. I believe that one variable could have been my presence.  I learned that caterpillars are pretty fast and that they can find food when they need to.


How Heat and Cold Affect Caterpillars' Growth

Robert B

As a group we experimented with living monarch caterpillars by putting three under a heat lamp and three without a lamp.  We did this to find out what the best growth pattern would be.  It showed that colder temperatures put the best growth pattern out.  Some sources of errors that might have existed would be that the containers were different, and by the end of the experiment one of the caterpillars had died.  Two new things that I learned are that caterpillars have the best growth using outside temperatures, and that I can identify male-female monarchs.


What Type of Milkweed Do Monarchs Prefer?

Justine F, Crystal Y

Our group took six monarch larvae and split them into two groups of three.  Then we planted milkweed in a tank and put three larvae in it, so this group ate the live milkweed.  The other group ate picked milkweed.  During this experiment we measured the monarch's length and width, to see how much they had grown.  Our hypothesis was that the group with the live milkweed would do much better, but our hypothesis was not proven because of too many deaths.  Two larvae died that were in the live milkweed group, and one died from the picked milkweed group.  We think that a parasite killed them.
