A Monarch's Meal Plan

In this experiment, we sprayed five tropical milkweed plants with a Dawn® dish soap and water solution. We also had five tropical milkweed plants that were not sprayed with the Dawn® dish soap and water solution. We placed six aphids on each of the ten plants. For four days we checked to see how many aphids reproduced on each plant. We found that more aphids reproduced on the non-sprayed tropical milkweed. The aphids did not produce as much on the Dawn® dish soap and water solution sprayed plants.

Container Crisis

For our experiment we took twelve 3rd to 5th instar monarch larvae and put six of them in six 1-pint  containers and six in six 6-quart shoe boxes. Every day we fed them each one piece of milkweed, measured them, and measured the area of the leaf they had eaten. We wanted to find out how the size of the container (pint verse 6-quart shoebox) affects the amount of milkweed a Monarch larva eats and the growth of the larva. The total average for the small  container was 3 centimeters per day and the large container’s was 6 centimeters. We concluded that the size of container that a monarch larva is  in does affect its growth and how much it eats.

Honey Gut Butterflies

I started my experiment bygetting three butterfly cages and setting them on a table near some light. I place around 12-15 monarch butterflies in each cage. Then i put two sponges in each cage absorbed with homemade nectar (honey and water). I put three different solutions on each sponge (40% honey, 5% honey and 20% honey). I was wondering how the different amount of honey in water would affect the mortality and weight of a monarch butterfly. My results are, the monarchs drinking 40% honey will live the longest and weight the most. This project helped me realize that eating too much sugar doesn't just affect humans weight.

Milkweed Madness

I did a field study kids in my school. We learned about milkweed, which got me interested. I was very interested in the pods themselves. I wanted find out where most of the pods were located on the plant and the average number of seeds. I did my project at Spring Peeper Meadow. I first counted 500 common milkweed plants. I collected 20 pods from the plants I had counted. In the end I went with my hypothesis one. This stated that most of the pods on a milkweed plant are located on the top two tiers and that that the average number of seeds in a pod is 152 seeds. I think this contributed to the common knowledge of common milkweed.

The Great Migration

We decided to tag and release our classroom raised monarch butterflies. As a class of 76 we released them 5 at a time on an open field. Each person wrote down an approximate direction their butterfly went from a large compass placed it the middle of the grassy field we worked in. The majority of them went south or southwest, though a few went in different directions. We discovered that even if you release them to the north they still have the instinct to go in the southern direction. We now know that they are very directional in the fall.
