A group of students, including myself, did some research at Stoney Ridge Farm in New London, MN.  In 2004 we looked at a total of 1357 common milkweed plants and found 201 monarchs; 14% of the milkweed plants had monarchs.  In 2005 we checked a total of 740 plants and discovered 72 monarchs; 9% of the milkweed plants checked had monarchs. My hypotheses were:  H1:  The year 2005 will be more productive than the year 2004.  H2: The year 2004 will be more productive than the year 2005. Null: There will be no significant difference between the monarch population in both years.
I found that hypothesis 2 was supported by the data collected.  This may have been because in 2004 we monitored more plants and the field we monitored was accidentally plowed.  At first we thought it was a disaster, but the plowing actually caused new milkweed growth.   To further test this possibility we are planning on mowing part of our site next year so that we can collect data about monarch preference.

Monarch's Across Minnesota: For Better or For Worse

Elliot E, Chase A

Our experiment was done to find out how our monitoring site compares to others in Minnesota. We had a great time monitoring our site all through the summer. We used the protocol from the Monarch Larva Monitoring Project. Our site seemed to produce a lot of monarchs and it led us to wonder how it compared to others. It turned out that our site did better in 2004 and not 2005.

      My question is: Do sow bugs like one food more than another?  I have collected many sow bugs in the woods near my house.  They like moist, dark places.  I decided to try our four different moist foods to see if they had a preference.  I put bananas, potatoes, leaves, and apples on a pizza pan.  On each trial I put 4 sow bugs or pill bugs in the center of the pan, making sure each one was on its feet.  I covered the tray with another one so that it was dark.  I waited for four minutes and they I looked to see where each one had wound up.  I did this 10 times.  The sow bugs liked the potatoes the most.  I would like to have some races to see how fast they will run to the potatoes.  I also made a maze to see if they will find their way through more quickly if a potato is at the end.  I am anxious to see how these turn out.
