Are ants picky over their food? Do they have any preference?
The purpose of this experiment was to determine which flavor ants are most attracted to.
Do cockroaches have a sense of direction?
First students make careful observations of cockroach anatomy and behavior. Due to the reputation of the cockroach, students find them intriguing subjects of study. Assessing the behavior of these insects in a maze, allows students to decide if the cockroach manifests learning or an inability to learn. The strongest piece of this activity is challenging students to design their own controlled expe
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
What are the effects of heat, moisture, and ventilation upon the development of the chicken embryo in an incubator?
The avian embryo is amazing and exciting. In only three weeks, a small clump of cells with no characteristic features of any single animal species changes into an active, newly hatched chick. A study of this transformation is educational and interesting, and gives us insight into how humans are formed.

This is an activity which uses frogs or toads to demonstrate scientific method, by measuring the respiration rate, as well as the other external features of the live specimen. The kids enjoy working with the Arizona Toads.
Diffusion and osmosis in animal cells
With the use of eggs, this experiment shows you how different solutions affect an animal cell. The experiment also answers the question of whether substances can pass through a cell membrane.
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.
