DYO #2: Fruit Fly Population Investigation

The problem is how does changing the number of females to males effect the number of adults at the end of 3 weeks? My hypothesis is if I put 2 females in one jar with a food source and 1 male for 3 weeks then the number of adults would increase rapidly. My background research says after having sex the females house the sperm of the males so they may continue to reproduce.

 My data supports my hypothesis and shows how two females and one male and other combinations reproduce slower and faster, my data also proves that with two females and one male they'll reproduce more because there are more females to reproduce and they'll reproduce twice as fast.

In conclusion changing the ratio of male to females, can increase and decrease the amount of adults at the end of the 3 weeks.

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

          This week in science we read about H (habitat loss) I (invasive species) P (pollution) P (population) O (over consumption) we also briefly visited a bus that ran on sun light and was good for the environment. inside the bus we tested alcohol and accidentally nicotine on a Daphnia which eventually killed it because nicotine slows down the heart rate while alcohol slow it down.

          This week in science we learned about H.I.P.P.O and how we use Daphnia to test the effects of drugs on humans and also to test the quality of fresh water. We learned that Daphnia are easy to find, they live in fresh water from puddles left by rain to lakes in the suburbs. We learned that due to each part of H.I.P.P.O has a huge effect on the world around us.

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

    This week in science we identified the different stages in the life of Dorsophlia Melanogaster (Fruit Flies), we also identified the different sex's based on their physical appearance. We observed how each stage of the Fruit Fly development is different from the last.

   
     We learned that the life cycle of a Fruit Fly is a total of 16 days. We learned female Fruit Flies can house the males sperm for life reproducing whenever needed. We learned male fruit flies have a darker bottom while the females are lighter. We learned how the Fruit Flies mate and reproduce quickly.

Post 7: This Week in Science (Ecosystems)

In the last two weeks in science we designed our habitats and drew what we though it would look like. We also took a trip to this garden and we gathered things for our terrarium like worms, beetles, centipedes, and millipedes. We also took a test and made our own corrections. We also researched one organism in our terrarium.

I learned the scientific name for a garden spider, I also learned that the worms fertilize the plants and soil by leaving behind castings as a natural compost type material. I also learned centipedes are poisonous and Garden Centipede have venom claws directly behind their heads. They use these claws to attack prey.

I'm not sure what the venom of a garden centipede would do a human. I also don't know what the centipedes reaction to the spider would be, maybe they's fight because they're both predators.

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

   This week in science we fed our spiders and added one more spider to our groups, we are also still trying to solve the fruit flies problem. We made a chart to help us solve the fly problem and graphs.


   This week I learned how a cellar spider wraps its prey up in webs and carries it around for later. We also learned that if two spiders are in the same tank they'll most likely fight if their both males.

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

   This week in science we tested the fruit fly problem to see if we had the right answers. After one day

there would be 40 eggs, on day 15 there would be 600 eggs, 3 adults 1M(male)/2F(female). At day 16 their 

would be 560 eggs because some eggs hatched leaving 43 adults. We charted our results.

   We learned the how to determine if a fruit fly is a male or a female. We also learned females have 20 

eggs each day. We learned the flies take two days to become mature adults. We learned the fruit flies have 

a life cycle of a total of 16 days and can live up to eight  weeks as adults.

This Week in Science: Energy Transfer

We drew a food chain and a energy pyramid with the organisms in our fantasy habitat. We had to write definitions of words used in a food chain and energy pyramid. We wrote different names for the subjects on our food chain. We also had time to make up work.

We learned how energy pyramids show the amount of energy that is consumed when organisms are consumed. We also learned that food webs are a set of interconnected food chains that show the feeding relationships in an ecosystem. We learned how energy transfers from organism to organism in a food chain.
