Ladybugs Favorite Color?

Christopher D, Nick K, Christian V, Steven M

For an experiment on color, we chose ladybugs primarily because they would be fun and easy specimens to work with.  We wanted to find out which color of paper the ladybugs preferred to have their meals on.  We gathered different samples of colored paper and decided to only work with the following colors: blue, purple, yellow, and green. We placed grapes, a known favorite food of ladybugs, on colored squares of cardboard, and began our observations. Green was the preferred color that the ladybugs ate from.  We believe that the ladybugs relate to the color of green because it simulates leaves, which is their food of choice.

Mealworms Reaction to Light

Megan F, Emily F, Zach W, Rawlin K

We chose to do this project to find the truth about the mealworms´┐Ż reaction to light.  Our challenge was to find out how much light is needed for the mealworm to react.  We put 20 mealworms into a covered shoebox.  The lid had 7 square holes in the top, ranging from .5 cm to 3 cm and enlarging .5 cm each square.  Once we reached 3 cm we increased one full cm to 4 cm.  We recorded the data at the same time for seven nights.  After discussing our hypotheses we thought that the mealworms would be attracted to the smallest square hole, but that hypothesis was not supported.  Our results showed us that mealworms were not attracted to light at all.

Was that a Chirp?

Jillian G, Allie P

Our research was designed to discover how temperature would affect a cricket's chirping.  Our goal was to discover if a higher temperature would cause the crickets to chirp more or, if a lower temperature would make them chirp more.  For this project, twenty adult crickets were kept in a plastic storage box.  We counted the number of chirps heard every 15 seconds with each five degree mark beginning from 65F and ending with 85F.  Our results concluded that the number of chirps went up as the temperature increased. 

What Food Do Darkling Beetles Prefer?

Alex N, William R, Tyler S, Andrew J

We selected Darkling beetles for an experiment because we wanted to work with a beetle and Darkling beetles are unique and interesting.  We decided to try and figure out which food darkling beetles preferred, apples or potatoes.  To answer this question, we put wheat bran in the bottom of a plastic container.  Then we took two equal sized pieces of apple and two equal sized pieces of potato and put them at opposite ends of the container.  We put our beetles inside the container and replaced the lid and began to collect data.  From our observations we would say that the Darkling beetles preferred potatoes to apples.
