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

  • Paragraph 1: What did you DO this week in science?
  • we went on a magic school bus to learn about daphnia which is a small species thats is often  found in pounds. we also was working on our fruit flies like always. we also worked a little on our no impact man research. 
  • Paragraph 2: What did you LEARN this week in science
  • this week in science we worked daphnia ;) which like i said is small creature that is often found in pounds its also what most scientist test their drugs on because the small thing has a lot of simulators with humans. when we tested the achol on the little thing the heart beat started to slow down and eventually it just died 
  • Picture: Insert a picture of Daphnia or some introduced species.

  • i chose this picture to show what it looks like on the outside
    i chose this picture to show what parts is what parts .

DYO #2: Fruit Fly Population Investigation

  1. Problem (Question):  how many flies would be in the vial after 3 weeks
  2. Hypothesis:at the end of of 3 weeks there would be 646 adult flies in my vial because i put 2 males and 4 females in my vial because everyday a adult female fly lays 2O eggs everyday and then it takes the flies 16 days to become adults while its going thru every stage.
  3. Background Research:Fruit flies has 4 different stages in its life and while it was in the vial i got to see all the stages like egg, larva, pupa, adult. it was very cool to see how much they change in only 16 days every week we would get to look at the vials and see the changes. like for example the first week we had the same flies in there but we was some eggs and a few flies died but we still had some growth in there. the first stage looks like a rice w a small black dot the second stage a little nasty is a small white warm w a black dot. 
      4.   Procedure:
  • Step 1: I set up three different vials with a food source and 2 males and 4 females in each one. This made a ratio of 2 to 1 (2F:1M). 
  • Step 2: Place vials together in bin at room temperature.
  • Step 3: Check vials each week and record observations (i.e., number of adults, number of pupae, existence of eggs and larva, any strange or unusual activity)  
  • Step 4: At the end of 3 weeks (on day 21), use FlyNap to put flies to sleep. Empty out sleeping flies on an index card, record the number of adults on your data table and put the flies back in the vials. 
        5.  Data Table and Graph (click here for photos of your graphs -
  1. Analysis: each week i would have to see 3 different vials to see the differences in each vial. the vials i had to check were vials 18, Sjrs, &2O vial 18 had 7O adults, Sjrs had 114 and 2O had 67 adult flies after 3 weeks. i expected to see 646 in vial 18 but because it had some frailer flies the first week i believe we was not so successful in the the entire experiment.  so my data did not support my hypothesis.
  2. Conclusion: Overall i wanted to find out how many adult fly's would be in the vial after 3 weeks because it was the investigation in my class. if i could improve my experiment i would have put the flies in a more comfortable environment so that maybe my calculation would have matched w my data better.

Post 11; this week in scince (no impact man)

 NO IMPACT MAN year project is about a man that tries not to use nothing harmful for the planet and see how his family and him could live with no electricity, not making any garbage, and not using any type of transportation that could harm earth in anyway. so his family (wife & daughter) have to deal with that for a year.


the things that no impact man does to not impact behavior of the planets are not using any light,transpiration,out side food or any type of food that has to travel to him because its harmful so basically anything harm full in the smallest ways were not used by his family for a year.
the things he gave helpped the world because he wasn't doing anything to harm the world.


My first reaction was sounds coool are they going to be like in a forest or something but then i saw they was in the city and the wife was having to make a lot of changes that i wouldn't wanna make. so i started thinking this man is nut.
(i hope you lived to grade this )

1O;This week in scinece (fruit flies DYO part 1)

This week in science we didn't do much since we only had three days this week. On Wednesday my group observed our spider habitats. And we also learned about the life cycle of Fruit flies. On Thursday we were introduced to the Fruit Flies. My group chose to make it 2females and 1male so that we could have alot of flies and the could make babies daily.

This week in science we learned about fruit flies and how every 16 days an adult fruit flies baby becomes adults. they lay 2O eggs everyday and then it just keeps repeating.
 

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

 We put the the fruit flies in the container and then try to calculate the how many fruit flies would be in there after 3 weeks i only came to school one day so i don't really know what els happened in science.the days that i did come we put flies to sleep with flies to bed which is like a little medicine looking like glass jar very small that puts flies to sleep so that we could put them in a vial.




I learned that you cant just put fruit flies in a container and hope they live you have to put a lot of food and put more than 3 fruit flies because the chances of the flies die-ing in there are big so we put like 8 in there im not very sure. also i learned that you cut flies to sleep. we learned too, how to tell the difference between a girl and boy fruit fly by there bottom if its dark or light.  





  1. HypothesisIf... IF no female or male fruit fly has reproduces then after a few days the flies would start dyeing. if the fruit flies reproduced according to my calculations there should be 646 adult fruit flies at the end of 3 weeks.

      Post 7: This Week in Science (Ecosystems)

      The last two weeks in science we have been creating a new spider habitat for a spider with our groups of 5 people we started out buy drawing how we wanted it to look and showing the different little small creatures that would live in there and what type of home we would like to make for our spiders.   

      I learned that you can seal a tank with a living animal in it and it wont die as long as you have plants and other small living things because the animals feed the trees with the waste of oxygen and the tress keep the living things living with the oxygen they let out. oxygen is there waste.

      
      my habbitats first picture ;)

      inside view ;) after the 2nd spider moved in 

       how does everything stay mosit and wet inside my habitat ?
      how do we know it if the spider likes the habbitat ?
      does the spider get loney?

      post 8; this week in science ( fruit flies part 1)

      this week in science i came to school only 2/3 days and so yesterday my class mates and i were trying to figure out if how many flies was in a small container flying around and that kind of tricky because if you look at it it would look like a million fruit flies flying around so instead we deiced to try to figure it out in a way that we wouldn't eve have to look at the flies.

      so we learned that if we put 3 flies to start with in there if there all adults the females lay 2O eggs a day and it only takes 1 day to lay a egg 7 days in the larva processes 6 days in the pupa and then 2 days to become adults and then they lay 2O eggs a day so in 16 days there should be 323 flies in 16 days in the small container then the process starts again.
