DYO #2: Fruit Fly Population Investigation

 Problem (Question)How does putting 2 females and 1 male fruit fly affect the number of eggs after 3 weeks.
 
         Hypothesis If i put two female and one male then there shall be 322 adult of flies because they all lay 20 eggs a day on every two weeks they become adults.
        Background Research In my research we had to  find out how many fruit flies would lay eggs after three weeks.  My group choice two females and one male.  So females lay 20 eggs and the male doesn't carry any eggs.  The Drosophila Melanogaster cycle starts with the egg (1day) then the Larva which takes (7days) then the pupa which takes (6days) and then it becomes an adult in (2days) , and about  takes what I'm researching about Fruit  flies.
        Procedure In step one- My group had to choose a combination with two females and a male to see every three weeks they would lay eggs, so in 
Step two-We put the flies to steep to determine to see which one was male or female, and then put them in an vial, also In
Step three- we had to make an observation on our vial weekly to see any changes, Then
Step four- In the end of the three weeks we are going to put them to sleep and count how many adults there are. 

 Data Table and Graph (click here for photos of your graphs)

      
  
        Analysis :  In our data we used a bar graph because we did not measure it each week.  If I put my combination of 2 females and 1 male then there should be 322 adults of fruit flies because they lay 20 eggs a day on every 2 weeks, they become adults.  My data does not support my hypothesis because there wasn't 322 fruit flies.  I think my hypothesis doesn't support my data because we didn't measure it each week, so it didn't come out to 322 fruit flies.
        Conclusion: My overall experiment was geting 115 fruit flies then 322.  How I go about getting the answer was counting the fruit flies by putting them to sleep.  What happened in my experiment was that my hypothesis was wrong.  My data did not support my hypothesis, at all because I get less than 322.  One source of error In my experiment is the measuring part.  My data and hypothesis could've gone wrong.  How I can improve my experiment If I did it again is try to measure it each week.  One question I'd like to investigate further is if there wasn't fruit flies?.

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

    This week in science we went to this truck that had people that were scientists.  We got to see the little creature known as  a Daphnia.  They these little things in the water and we put Alcohol and also Nicotine.  We did that to see if there heart races or slows down.  And Lastly we got to time it to see if it changes. 

   We Learned that with 10% of Alcohol the heart starts to go faster.  And with 20% it Slows down really fast.  And also we learned that before experimenting on humans you should experiment on model organisms.  Also the Daphnia's body is strange it eats and poops in like a few seconds depending on how long their food takes to digest.  And lastly we found out that Daphnia's are not a suitable model organism for testing the effects of drugs on the cardio-vascular system.

post:#11 this week in science(no impact)

   No impact mans year long project was about how he wanted to change his environment.  He decided to use less of everything then he started to cut back on everything.  He made his family stop doing things that New Yorkers love such as driving,flying,getting take out food,shopping,watching t.v,using elevators,and lastly stop using  pampers for the baby.  Which was weird because they have a baby but they made it work.  And also they didn't have tissue because that was bad for the environment.

   No impact man did a lot of things that changed the environment that hes in by going to local food places.  Also he put a solar pan instead of using electricity.  Also he made the worms he got eat the left over food he had instead of producing garbage.  Also he had to keep his food cold all he had to add was water.  And lastly he made his family follow the phrase reduce,reuse,recycle.

  My reactions at first was this wasn't that bad I think I want to try it.  Because I want to cut back and give more to my environment to make it better.  However as I got through the movie well not all of it I changed my mind because I can't give up all the things he and his family did.  And I know my family won't approve of it all because we are true New Yorkers. 

post 8: This Week in Science (Fruit Flies Part 1)

    This week in science we created our hypothesis, created a graph and attempted to figure out how many eggs will be there at the end of three weeks.  And also we had to use a table and make a graph.  Which required a lot of math.  Also we had to get in groups to guess how long it will take them to get through all the stages.  And we are getting spiders to put the fruit flies in the tank.
   We learned that a female lays 20 eggs a day.  And on the 14 day they turn into adults.  And also the female don't have to mate.  Because it has a sperm Store inside of them.  And lastly the female fly is bigger then the male fly.

   

Post#7:Ecosystems

    We went to the garden.  Also we got insects to put them in our spider habitat.  We had to pick them up with either a stick or a bag.  And also we had to dig under rocks and logs to get our insects.
They were nasty looking and the were crawling around.
 
    We learned why millipedes crawl up when they touched.  And Also we learned that there are many insects in the garden.  Also we learned that their are different insects that just be up in the dirt.  And we learned that moss be living under the sea.  And they give oxygen.

    Im unsure about how is all my insect going to survive in my tank.  I say that because when my spider comes it's going to eat all the insects I spend my time getting.  Also im unsure about how they going to get the food they need with the rocks under the dirt.  And lastly im curious about what my spider might like.  Like is it going to like the insects i got or is it going to die of hunger

         

Post:#9This Week in Science (Fruit Flies Part 2)

  This week in science we did the if then because format on our notes section.  Based on our observations and it didn't match up.  Also we made stations to go to to learn new ways to observe our habitat.  Also we we had to make a fruit fly thing to look back.  Lastly we put the furit flies in a tube with food at the bottom.
  
    We learned to write a clear and organized DYO.  Also we learned to organized our data in tables and graphs.  And we did a post on what we did.   And also we how many babies they have.  And Lastly we learned the difference from the male and female.

  If i have 2 females and 1 male and I put them in a jar.  Then I expet to observe about 40 eggs the next day that we put them in that jar.  Because it states that each females lays 20 eggs per day and we got 2 females so that's 40 eggs.
 

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

This week in science we Did a hypothesis and background information. And also we had to Organize our data and too do the graphs.  Also we too do tables for the graphs.  Also we had too write a chart in a scientific and organized way. And lastly  we had to do a independent Variable and a Dependent variable to write a question.

   This week in science we Learned how to identify the different stages of life in Drosophila Metanogaster. Also we created a justified hypothesis by solving a problem about fruit flies.  Also we Learned how to do a hypothesis in the if..then..because format.  Also we  We did some research on flies and found out what day they give birth and when they turn into larval and how many days it take.   And lastly we ended that with a little project and thats how we got how many days the cycle keeps going on.

This Week in Science (Spider Habitat Design)

   This week in science for our spider habitat design, we brain stormed and found research about them.  Also we did a problem and we had to find the solution for example we showed a a little table that said Build--->test and evaluate--->Redesign.  Also we had to get into groups and show the environment of our spider in the tank.  Also we had to use our brains to play a game that I didn't really like that much it was called Carbon and oxygen cycle.Through an ecosystem Also we had to get ideas off of our group members.

   This week in science we learned that their are many things that a spider would eat well that lives in the dirt.  Also we learned about the carbon oxygen cycle.  Which was a game but at the same time it gave important information.  It told how the carbon moves around from the the great big trees to down below in the deep blue sea.  And lastly we learned about how our animals in our spider habitat will change after the spider comes.

This Week in Science (Carrying Capacity and Relationships)

    This week in science we Played a game as a class named "Oh Deer" on the roof.  To show the Carrying Capacity and how fast the population decreases.  Also we learned seven vocabulary words.  And just yesterday we played a card game to show how organisms interact with their environment.  Also we looked  through our partners and give them feed back on what they should add or take out, and we did a worksheet.

    This week in science we learned some cool vocabulary words like....
Limiting Factors-the available energy,water,oxygen,and minerals, and the ability of ecosystem to recycle the remains of dead organisms(activities of bacteria and fungi).

Carrying Capacity-the number of organisms any environment can support.

Living Organisms have the capacity to produce populations of unlimited size.  But available resources in their environments are finite. And......

Mutalism
Commensalism
Parasitism
Predator/Prey.

   

"This Week in Science: Energy Transfer"

   This week in science we did a lot of new things.  For example we got new vocab words and we made a food chain.  Also we did a food pyramid based on our creatures that we picked.  And Lastly we had to make a model of it well both of them.  The food chain and the food pyramid it was really fun.
     We Learned new words that can help us in our everyday life.  For example we learned that the Producer is an organism that makes their own food like grass.  And we learned about primary consumers, secondary consumers, tertiary consumers, omnivore, herbivore, carnivore.  Too break it down  primary consumer,secondary consumer,tertiary consumers all go with each other like each one gives off energy to another organism. And lastly omnivore, herbivore, carnivore are certain types of animals.

                                 

This Week In Science

On the first day of this unit, we set up our blogs and created our first post. Our first post was called First Impressions. We wrote about our feelings on frogs and blogs. I did not know anything about a Frog i only seen them in movies.I did not know what the dissection would be like. On our second day, we finished fixing up our blogs and we updated our profiles. Then, in our notebooks, we wrote some cool facts that i didn't get to do yet but i will.I was very nervous! Once i saw the frogs insides I did not want to touch the frog at first, so I decided to be the Frogtographer and the Person who shows my group  what too do and touch. I had to take pictures of the dissection as we worked. On Thursday,we got to remove the organs and identify them on a Sheet. I was not scared anymore, and decided to try removing some organs with Jamilex and Chris.

     I learned that frogs have some organs like us humans do.  also i Learned that they don't have the best smell when their dead.  And I learned that they have a heart, lungs, liver, intestines, stomach, pancreas, and spleen.  They have other organs but those are unknown to us because we didn't find them.  I learned how to tell if a frog is a boy or a girl by looking at their thumbs.  If they have Fat and big ones their a boy.  We Named our frog So Many names i don't remember so I'm Going to name him Tommy.

 This picture shows the organs that we pulled out of Charlies body and examined it on a worksheet.  I chose this picture because I think that it shows what we learned about frogs.

This picture shows my group taking out Charlies Stomach.  I choose this picture because it shows how that Particular organ has too come out.

This picture shows my group opening Charlie Mouth.  I choose this picture because I like how the mouth is opened.

This picture shows my group opening Charlie up the center.  I choose this picture because you get to see how everything in the body looks.

This picture shows my group opening One Side of Charlie.  I choose this picture because it shows how we had to hold the frogs skin down which was weird.

This picture shows Charlie heart,Lungs,stomach and intestine.  I choose this picture because it was hard to get the skin to stay down and when we finally got it  i caught the picture.

First Impressions

     I Always Wanted To do Dissect some thing but never frogs but it should be cool.  I really can't wait to see what's inside the frog.  Do it have Parts like us Humans.  I really am looking forward to working with the frogs and examining their bodies.   I hope i don't get sick by looking at the insides.

My fantasy Habitat

what i did in science was great.  We had to pick a animal and learn things about them.  For example i picked a sea star(Kit-Kat).  And the star fish has many fascinated things about him that nobody knows like their are thousands of them in every ocean.  Also we had to make a picture of them and color it to show their habitat.
    We learned about different habitats. And we learned about different animals.  And how they live and what is surrounding them.  Also we learned what our animals eat for example star fish eat mussels, clams, and oysters.  They are really interesting creatures And i had a great learning experience Learning about them.
