DYO #2: Fruit Fly Population Investigation

Problem(Question)-How does putting two females and one male fruit flies in a vial affect the number of adults after three weeks?
Hypothesis-If i put two females and one male in a vial for three weeks Then there will be 323 adults by the end of three weeks Because everyday 20 eggs are hatched and each egg takes 14 days to become an adult. So by the 21st day there should be 161 adults. Then times that by 2 because there is two females.
Background Research-A fruit fly takes two weeks to turn into an adult. The first day the egg is laid. The next stage in the fruit fly cycle is the larva. The fruit fly is in the larva stage for seven days. After the larva stage comes the pupa stage. The fruit fly is in the pupa stage for six days. Then after the pupa stage, the fruit fly is an adult. After the fruit fly is an adult, two days after they can start having babies. Although the fruit fly cycle is short, they produce twenty babies a day and keep their cycle going on and on.
Produce-Step1-My group had to pick a combination of two females and one male.
Step2-We put the combination of fruit flies to sleep and determined which ones were male and female, then put our combination in a vial.
Step3-We do weekly observations of our vial and two other groups' vial with the same combination to see the difference.
Step4-When the three weeks are over we are going to put all of the fruit flies to sleep
and see how many fruit flies we have.
Data Table and Graph

Analysis-I looked at the 3 vials that each had one male and two females. Each vial had a different number of adults at the end of three weeks. Vial one had 110 adults. Vial two had 210 adults. Vial three had 143 adults.
In the beginning of my experiment, I hypothesized that if I put two females and one male in a vial for three weeks with a food source, then I expect 323 adults at the end of three weeks. I
thought this because everyday 20 eggs are hatched and each egg takes 14 days to become an adult. So by the 21st day there should be 161 adults. Then you times that by 2 because there're two females. My data does not support my hypothesis because the average number of adults in my three vials was 154.3. This is nowhere near what I predicted. It is way to lower.
There are many reasons why my hypothesis and results are wrong and way off. One reason is because some flies could have got stuck in there food and died. Another reason is because some flies could have got stuck in the foam at the top blocking them from escaping the vial.
Conclusion-In my experiment, I tried to find out if the number of fruit flies I predicted there to be after three weeks would support my hypothesis. After predicting, my group and I set up our experiment and after my experiment my hypothesis didn't match my data. This could be because of flies getting trapped in there food source or the foam at the top of the vial and dying. If I had the chance to do this experiment over I would defiantly use something else besides a vial so the flies wouldn't die and easily get caught in the food or foam.

Post 12:This Week in Science (Daphnia and Introduced Species)

This week in science we did a lot. One thing we did was go on a Bio-Bus. On the Bio-Bus we had a water flea under a dissecting microscope. we did a three trial on how many time it's heart was beating in 10 seconds. Then we did it again but only this time we added alcohol.
This week in science i learned a lot. I learned how four different types of introduced/invasive and species can negatively disrupt an ecosystem. Another thing i learned was about zebra mussels, kudzu, and european starlings. i learned there descriptions, why was it able to take over, what did humans do, how was it harmful, and what now.

this picture shows all the details of a water flea aka  Daphnia. i chose this picture because it shows all the details like whats what and the insides.

Post11:This Week in Science (No Impact Man)

The No Impact Man's year long project was to live in new york city with his wife and daughter without hurting the environment. The no impact man and his family feel that using multiple items such as plublic traportation and other things.
The no impact man's behavior lowers his negative impact on the environment. One example is when he used worms to eat his family's scraps of food instead of producing trash. Americans produce 16,000 pound s of trash every year. Another thing he did was he used a solar panel to write his blog throough his joourney to not hurting the environment. Last but certainly not least no impact man and his family got rid of there fridge and use a flower pot with sand around the edges. when the sand around the edges is wet,it some how keeps food and drinks at a good temperature and keeps food fresh.
When watching this documentary at first i thought this was stupid. But getting into the document mor ei got more intersted. i thoought that what he was doing was very considerate of him to think about the environment.

Post 10: This Week in Science (Fruit Fly DYO Part 1)

This week in science we did and learned a lot. This week David spit the room into three stations. Melissa Alyssa and David at each one. At the first station with Melissa we wrote out our procedure explaining the steps with fruit flies. At the second station with Alyssa we wrote our question using the Independent variable (IV) and Dependent variable (DV) and wrote out background research. At the third station with David we wrote out our hypothesis using "if...then...because".This week in science we learned how to write a DYO in a clear and organized way. Also we learned to organize our data in tables and graphs.

Post 6: This Week in Science (Spider Habitat Design)

This week in science we researched about spiders. Also we thought about how we would make a habitat for our spiders. Another thing we did is was we got into groups and discussed our ideas for the spider habitat with each other. Then we put all our ideas together and made one big habitat and drew it out on big chart paper. We included...
-side view
-labeled all parts
-predator/prey relationship
-biotic and a-biotic
-limiting factors
-supplies
-group members name

In science this week I didn't really learn that much to be honest.

Post 5: This Week in Science (Carrying Capacity and Relationships)

     This week in science we did a lot. One thing we did was play a game called "Oh Deer!" Unfortunately, I was absent that day. But from what my classmate, Kennedy, told me, the game sounds pretty cool. Kennedy said that they went to the roof to play! We watched video to help us understand our new vocabulary words. Also, we played a card game.

    This week in science I learned new words. I learned what commensalism, parasitism, mutualism, and predator/prey means. Commensalism means one organism benifits while the other one doesn't benifits or mind or get harmed. Parasitism means when  one animal needs another. Mutualism means two organisms helping/trading with each other. Predator/prey means one animal that eats another.

Post 4: This Week in Science (Energy Transfer)

This week in science we took our fantasy habitat animal and made a food chain and a energy pyramid. Also we study new vocabulary words.
This week in science i learned something called the "Com/wheat" problem. i also learned that not killing the cow right away mean less energy for the cow and less energy you.
