Boundaries and Size

Amanda E, Dasha D

   Our group did an experiment on Monarch Caterpillars. Our experiment is based on Size and Amount of Space. We believed that the more space a caterpillar got, the faster they would grow.

   We wanted to see how fast a caterpillar could grow depending upon the size of the container they were kept in.

   Results- Jessa's caterpillars were the biggest caterpillars, and they grew the fastest. Because Jessa's were in the biggest container. Dasha's, Ashley's, and Amanda's all died before reaching their chrysalises. We think it's because they were in the smallest containers.

   Our group agrees that we don't think that Ashley should've left her caterpillars at Dasha's house, because the environment they stayed in could've been the same and caused the caterpillars to die around the same dates. And the fact that Ashley didn't raise them herself.

   The two things we learned were: That you can't touch or play with the Monarch caterpillars, because it could kill them. And we also learned the difference between a Male, and a Female Monarch Butterfly, but you can't tell the difference between a Male and Female Monarch Caterpillar.

   Our experiment was based on light, and caterpillar growth.We grew our caterpillars under red light, green light, and regular room light, to see the effect of the light color on growth. Our purpose for the experiment was to see how light type effects growth and length of a monarch caterpillar. Our results were that caterpillars in regular room light grew around 29 mm, and caterpillars in red and green light only grew to 24-25 mm. One of the problems was that not all of our caterpillars made it to a chrysalis. We learned that caterpillars in regular room light grew more than any other color of light. We also learned the color of the light effects the monarch caterpillar on how much they eat, the caterpillar in regular room light eats more than the a caterpillar in red or green light. 

Name That Tune!

Our group performed an experiment comparing music type and caterpillar growth.  We had three people play different types of music.  We wanted to see what the effect of different types of music had on the growth of our caterpillers. We had one other person play no music to be our control.  The purpose of our experiment was to see if the growth rate of our caterpillers would change if we played different types of music for them.      The caterpillers that had country grew faster and formed a chrysalis sooner. The caterpillers with classical music played for them grew to be about 5mm smaller that the caterpiller with country. The caterpiler with rock music played for them grew to be smaller than the average caterpillar, but formed a chrysalis about the samw time as the caterpillar that had no music.  The caterpillars that had no music, grew to be about the average size for a caterpillar.  Our conclusion may not be accurate because we were comparing the growth of the caterpillars and we should of had at least one more person to compare to.  Two things we learned in doing this experiment are:  1. monarch caterpillars can grow with music affecting them in a good way 2. we expected the caterpillar with no music played would grow to be the biggest, but the caterpillar with country music had the best overall length.
