Does Temperature Effect Pupae?
Matt P, Joe K
Will a pupae put into a hot temperature (28 °C) will emerge more quickly than a pupae put into a colder temperature (3 °C)?
How Does Climate Effect The Emerging Rate Of A Pupae
The purpose of the experiment was to find out how the climate, or the weather over a long period of time would affect the emerging rate of pupae. I attached one pupae to each of my three boxes. I put one in the refrigerator, one in room temperature, and one in the heat pad box. The pupa in the refrigerator/cold climate took 33 days to emerge. The pupa in room temperature took 8 days to emerge. The one in the heat pad box took only 4 days. There were a few uncertainties, like the refrigerator door was left open overnight and the heat box with the heat pad was also left open. I did a test on how climate affects the emerging rate of a pupa. My hypothesis was correct, the pupa in the heat pad box took the shortest amount of time to emerge.
How Does Temperature Effect The Butterfly After Emerging?
I wanted to find out if butterflies live better in warm or room temperatures. I took two fifth instar caterpillars and put them in buckets; one on a heat rock and the other in a room with normal temperature. The butterfly emerging from warm temperature was bigger and healthier. Then we took two caterpillars and put one in a room temperature, and the other in warm temperature. The butterfly emerging from room temperature was smaller and less healthy than the warm temperature butterfly. I think that if I tested more butterflies my results would be more accurate.
How Does The Moisture Level Of Milkweed Effect The Growth Of Caterpillars?
John D, Zach E
The purpose was to see how the caterpillars grow in response to different moisture levels of milkweed. I put the leaves in a box with two sides: dry leaves in one side, leaves with 2 spritz of water on the other side. We placed caterpillars in each side. Then we recorded length of caterpillars in cm and recorded observations everyday. We placed the box in back of the science room by the window. We checked the box daily for changes in the caterpillars. The caterpillars with 2 spritz of water and the caterpillars with no spritz of water grew the same length, in general. Problem: the caterpillars went into pupae unexpectedly. Also, being close to the window, the sun may have dried out the leaves. The test ran smoothly, and we found out that the moisture level of milkweed doesn't affect the caterpillars' growth.
