√DYO #2: Fruit Fly Population Investigation

PROBLEM/QUESTION:

          How does (Independent Variable) the amount of females and males affect (Dependent Variable) how many adults there will be?

HYPOTHESIS:

          If (IV) I put two females and one male in a jar with food source for 3weeks then (DV) I will expect to observe 323 adult fruit flies. Because there are two females and one male and each female lays 20 eggs per day so on day 14 the first batch is born.

BACKGROUND RESEARCH:

       I've learned about  fruit flies and there life cycle. One thing I learned was D.Melanogaster will produce new adults in two weeks. eight days in the egg and larval stages and six days in the pupal stage. Fruit flies may live up to eight weeks under optimal conditions. I've also learned how to tell the difference between a male and female.

PROCEDURE:

      I chose the combination of two females and one male fruit flies. Then we put food in the vial. We put the flies asleep with fly nap Then you have to see if there male or female and put then in the vial. And then we put them by your tank. We will do weekly observations of out vial and two other groups vial then count the number of fruit flies after 3weeks. Then finally feed them to the spider.

DATA TABLE AND GRAPH:




ANALYSIS:

     My data show how if we put 2 females and 1 male fruit fly in a vial will repopulate and the data was lower then my guess. In my hypothesis I thought that i was going to end up with 323 but the adults I ended up was with 112. My data doesn't support my hypothesis because my results were lower then it. I think my data doesn't support my hypothesis because the fruit flies were maybe dead and stuck in the bottom, and didnt grow right since it was in a small vial.

CONCLUSION:


     My overall experiment was great we did this experiment to see how many fruit flies will there be in 3 weeks. Well we put 2 females and 1 male and we put them in a vial for 3 weeks and seen how many adults there will be. My data didn't support my hypothesis. One error in my experiment was the low outcome of adult. Maybe they died and got stuck to the bottom were the food was. We could add more fruit flies in the begging. One question i have is , Does fruit flies like to live in a pack.

POST8-THIS WEEK IN SCIENCE(fruitflys)

Well, fruit flies they are a cool topic. They are so little and nasty. I hate bugs, bugs are gross and they look really weird. Anyways, we have two females and one male! We are trying to see the process of fruit flies growth. I hope they do not grow because more bugs in this world is not good. Bugs are little creepy little crawlers. i Haven't checked on our fruit flies because i do not know were they are and if they have grown. They probably have grown a hole bunch. Well, this is fruit flies.

Ive learned about fruit flies and their life cycle. One thing i learned was Drosophila Melanogaster will produce new adults in two weeks, eight days the egg and larval stages and six days in the pupal stage, Fruit flies may live up to eight weeks under optimal conditions Ive also learned how to tell a diffrence between a male and female.

POST 7- THIS WEEK IN SCIENCE(spiderhabitat)

Well, my post 7 will be different from everyone else because i was not here when they did post number seven. My post number seven will be about my super cool spider habitat. My spider habitat contains of many non-living things and living things. Also my spider habitat is sealed in a container. I feel bad for my spider because it is probably really hot in there and all the bugs are dead most likely, and the spider is probably dead :(. To create our spider habitat we had to go to a magical forest and collected props from there and we made a wonder full habitat. Well, that is my habitat experience.

This Week in Science: Energy Transfer



This week in science I made a food chain. My food chain starts off with a bare as my tertiary. The next animal in my food chain is the wolf as the secondary consumer. My next animal is my fantasy animal which is a moose and my moose is the primary consumer. My last thing on my food chain is trees. The tree is the producer.  On my energy pyramid its the same things but in a triangle.


In science this week I learned how to make a food chain. A food chain has a tertiary, secondary consumer, primary consumer, and a producer. My food chain is about my fantasy animal I've learned that my fantasy animal the moose is a primary consumer. On my energy pyramid Ive also learned that the animals take energy from each other. That's what I've learned.  :)

MY FANTASY HABITAT :D

This week in science I created a fantasy habitat. In lesson one I chose a central animal. My animal I chose was a MOOSE;) Also i looked for other living things, non-living things, food
Container/Enclosure. On lesson 2 we looked for what biome our animal lived in. My animal lives in the Coniferous Forest. On lesson 3 we drew our fantasy habitat. We needed 5 biotic and 5 abotic in our habitat.

This week in science I learned that abotic is nonliving and botic is living. I also learned that my Moose lived in the coniferous forest. Fishes and Bears and tigers live there. There are mountains water and Trees, but like the christmas tress not just any trees. Well thats all i learned in science i guess. GOODBYE

goFROGGYgo first imperssions

Frogs are an awesome topic. I've never really seen a frog in person. I hear there green, slimy, can jump high, there tongues are long and catch flies with them. Frogs and blogs are a good topic I guess but it's hard finding something to say about them. I don't think I've had a blog before unless facebook is considered a blog then I have, if not then I've never bloged before. David said we are going to dissect frogs. I really don't want to because that's pretty gross! Well this is all I have to say about frogs and blogs and me I guess so im done

THIS WEEK IN SCIENCE


 This picture shows the frog is now empty. I chose this because it shows the end of process
This picture shows all the organs on the paper. I chose this picture because it has the organs on paper

This Picture shows All of the frogs insides. I chose it because its the insides.
this picture shows  frog is now opened and ready to exam. I chose this because its a cute picture
This picture shows  us cutting open a frog with our  scalpel, i chose this because it looks cool




 Things i did this week was dissect a frog. Frogs are pretty gross at first i was nervous because the frog was once living and yeah it looked kind of nasty and gross. But anyway we did like a million lessons on this frog thingy it was lots of work. The frog was really small and it had everything little and stuff.
Things i learned in science was you can tell what gender a frog is by there hand and stuff but i also learned that a frog when its pregnant has like a million eggs. Frogs are gross so that's all that i remember. i would have more just i dont got my note book. :)
