DYO #2: Fruit Fly Population Investigation

     How does changing the amount of males and females affect the number of adults in 3 weeks? I put in 2 females and 1 male then there will be 260 adults at the end of three weeks because each day both females will lay 20 eggs each and day 14 will hatch. We are doing an a experiment on fruit flies because we want to know how many eggs they will hatch in 3 weeks. On our research, we figuring out our question to solve and that question is how does changing the amount of males and females affect the number of adults in 3 weeks. In my hypothesis, I put if i put in 2 females and 1 male, then there will be 260 adults at the end of 3 weeks because each day both females will lay 20 eggs and day 14 will hatch.This is what we are doing in class so far. Step 1: we choose a combination FFM fruit flies. Step 2: We drugged the flies with flynape. Step 3: We set up a jar with media yeast. Step 4: identify which flies are males and females then put my combination together. Step 5: then put them in a jar with food in a hortizantel way. Step 6: observe your jar and another group jar. Step 7: we have to count them adults at the end of 3 weeks. In my graph, I have the numbers of hiw many fruit flies i counted. Then i put the numbers into a graph. If i put in 2 females and 1 male, then it will be 260 adults at the end of three weeks because each day both females will lay 20 eggs each and day 14 will hatch. My data supports my hypothesis by showing the information that is important and how many fruit flies my group counted. I don't think my hypothesis is wrong but it depends what the teacher says if its right or wrong.  We found the answer in our class but we find more information as a group. What happened in my experiment is that we counted our fruit flies in order to do our graphs. My data supports my hypothesis because it represents of how we counted the fruit flies and did it with the teachers. There's nothing wrong in my experiment but its up to the teachers to decide if its right or wrong. I could improve my experiment is by having more information so i could get a good grade. How does this experiment improve our science skills for next year.
