Carbon Dioxide, A Killer of Monarchs?

Bob D, Nicky O, Marlene R, Chris S

In our experiment we tested how different levels of carbon dioxide in the air affected the growth, development, and behavior in monarch larvae and pupae.  We decided to conduct this experiment because we were concerned about how monarchs would react to rising carbon dioxide levels in the air.  We found that carbon dioxide negatively affected the monarch larvae/pupae.  We did have some difficulties on our experiment ranging from carelessness to unavoidable moisture problems.  We learned that carbon dioxide does somewhat affect monarch larvae and pupae and other things affect them too.

Colorific Monarchs

Lee M, Cammi P

We experimented on how food color affects monarch larvae to see if they would change color.  If latex in milkweed leaves changes monarch color, why shouldn't food coloring change monarch color?  We were somewhat able to change their color.  We were uncertain whether the food coloring had a long-term affect.  We learned that monarchs change color when you change the color of their food and food coloring may be too toxic for the smaller larvae.
