Heather Shelton As a child I was fascinated by the soft glow of the summer fireflies. I used to chase after their tiny flashing bodies just to see if I could get close enough to one to figure out how they work. What is so engaging about them? Light is such a powerful force in our universe and the idea of an organism being able to create its own light is an incredibly exciting concept. How are t

How are ladybugs affected by insecticides?
The purpose of this experiment was to determine the effect of insecticide on ladybugs. I became interested in this idea because I know that ladybugs are beneficial insects. They live around insect pests, which leads to accidental spraying of the ladybugs. Farmers need the ladybugs to help keep down pest population, and need to avoid killing them accidentally.

How do pesticides affect cockroaches?
The purpose of this experiment was to test the effects of pesticides on insects. My hypotheses is that most of the insects will adapt to the insect sprays, but they will not survive the effects of the insect bait.

How the frequency at which a cricket chirps can be affected by external factors
There are several natural phenomena - the rate ants walk, the rate fireflies flash, the rate of a terrapin's heartbeat, and even the frequency of human alpha brain-wave patterns - that follow the Arrhenius equation closely. This page looks at one well-studied case, the chirp rate of the snowy tree cricket, oecanthus fultoni. This little cricket, shown below, is familiar to outdoor enthusiasts as a

How would a chicken's growth be affected by synthethic steroids?

Is an animal's sleeping habits affected by artificial light?
The purpose of my project is to see if an animal's sleep habit can be altered by artificial light. I think that you can alter an animal's sleep habit by artificial light. The reason I think this is because animals are not that smart, and it would be easy to confuse them. I am going to measure their activity during the day and during the night.

Is the aging process in fruit flies affected by oxygen's radical roles?
The purpose of this experiment was to find out if oxygen's radical role has an effect on aging. The hypothesis states that oxygen's radical role does have an effect on aging. Based on background information and previous experiments performed by scientists, oxygen's radical roles do effect the aging process.
