“One Fish, Two Fish, Red Fish, Dead Fish.”
I did a study on the manmade chemical Irgasan and its effect on fish. This chemical is not naturally occurring, but it has been appearing in our waters. How does it get there? It is found in antibacterial soaps. After people wash their hands it flows into the lakes. I set out to see if various levels of this chemical found in the water affect the young minnows that are hatched each year. My experiment at the highest level killed all of the fish, reinforcing the fact that this ingredient found in common products is dangerous to our water sources.
It's Getting Hot in Here - Take off your Chrysalis
Emily G, Paige S, Mikhayla H
Our question was, “How does the amount of sun affect monarch mortality?” We chose this question because we were curious to know how the sun would affect how long a monarch would live. We put 3rd instars into a rearing cage, put the tub in the sun, sun/shade, or shade, and waited to see how many days it would take for them to pupate and what their rate of mortality was. We concluded that monarchs had a higher mortality rate in the sun.
Monarch, Monarch Bring Us the News

The question we investigated was how does the amount of sun affect monarch mortality? Our summer was so hot and dry so that got us thinking about how would the amount of sunlight effect monarch mortality? We put third instar caterpillars in rearing tubs and kept them in the sun, sun/shade, or shade until they pupated. We concluded that the monarchs in the sun had a higher mortality rate.
Purple or Yellow? Your Choice
McCartney K, Taylor B, Hannah S
Our question was, “Which color flower will the monarch butterfly be attracted to?” We chose this question because we were curious about which color flower monarchs would choose so that it would be easier to find them. We placed yellow and purple flowers in a rearing cage and then observed which flower the monarchs chose in 1 minute. We concluded that monarchs were attracted to neither the yellow nor the purple flowers.
