Abstract

I wanted to know if there were more male or female monarchs.  I took the information from data sheets we kept in the classroom.  I don't think anyone really knows if there are more males or females.  My results were that there were 75 females and 63 males.  I think I could do a better job with my graphs.  I am not sure if they were completely accurate.  I learned where the monarchs migrate, what influence we have on that migration, and what some things are that we can do to help in Mexico.

Hypothesis

My guess is that there will be more female than male monarchs.

Procedure

1. Identify butterflies emerged as male or female.
2. Keep track of the numbers on a data sheet.

Materials

1. monarch butterflies
2. data charts

Results

I found that there were more females than males this year.  There were 75 females and 63 males.  I also looked at data from monarchs raised last year.  Those results were 41 males and 38 females.

Conclusion

I believe that there are probably an equal number of male and female monarchs in nature.  There was not a significantly larger number of females than males.  I thought that there might more females than males because they are the ones that lay the eggs.

What I Would Do Differently Next Time

I would get data from the other classes that were experimenting.  By looking at this larger sample, I could make a better conclusion.
