this week in science(fruit flies part 2)

this week we put 3 fruit flies in our habitat. this week we made an solution for the fruit flies question. we made a poster for this to show the math we did. we also started our experiment to see the results of the question. my group picked 2 females and 1 male for the experiment.we also got our spiders this week.
 we learned that females produce 20 eggs a day. they also have the ability to store sperm from the males.we found out that they have a short life span. we learned that eggs hatch in one day and take 7 days to turn into pupa and 6 days into pupa and then 2 days to mature into an adult.
my hypothesis is if i put 1 male and 2 female fruit flies in a jar with a natural food source they will mate and in three weeks time they will have produced 100's of eggs because the female lays 20 eggs each day in 3 weeks time they will have been 420 eggs produced x 2 would be 840 and in 7 days an egg will turn in to a pupa and so on with it evolution.

this week in science(fruit flies part 1)

we took notes about our environments.we also wrote down what we saw in our environment that was new. we also observed a jar of fruit flies.we had to estimate how many there would be in a jar if we left 3 fruit flies with a food source in a jar.we used a microscope to see the bugs in detail.
we learned facts about fruit flies and the diffrence between a male and a female is size. we learned that females could store sperm and reproduce frequently for days. we learned that their is steam on our tank because that side is against the wall so it hot. we learned that plants face toward the light.
i picked this picture because it shows the fruit flies which relates to what we are learning because we are learning about fruit flies.

this week in science(ecosystem)

this week we went on a trip to the m'finda kalunga garden. her we got dirt,branches,rocks and bugs for our animals habitat. after this trip we checked up on the habitat we made for the bugs. after this we wrote down changes in the habitat. we drew a new picture of our habitat to show the difference between our first design and the actual habitat.
this week we learned about how most bugs hide under rocks. we learned that our animals actually could survive with the tank sealed shut. we also learned about the abiotic and biotic factors in our habitat. we learned that a earthworms scientific name is lumbricus terrestris. we also learned that they eat decaying plants and also soil. i also learned that worms breath through their skin and when it rains their forced to go up from the dirt because they can drown this is why birds gather up when its raining.
i want to know why their is condensation on our tank. i also want to know where are our worms because they are not visible. i want to know what they because i dont know if they have any decaying plants to eat. i really want to know why we dont got a spider yet.  

this is a picture of my group in the garden i choose it because it shows how great we work together


i think this is a picture of moss either that or its someones habitat. i picked this because it is a picture that relates to my habitat because my habitat has moss

This week in science(spider habitat design)

This week we did lots of work. we drew a picture of our spider and what we want its habitat to look like. we had to find out how to let air in our without making holes because its been taped to not let air in. we also played a game called carbon cycle it helped us plan for our spider tank.this is all we did this week.

This week we learned how the carbon cycle works. we learned how to make our spider survive without holes in the tank.we learned how that will be getting  spider and that we will be designing a habitat for it. i learned how to draw our spiders environment.i also learned a lot about our spiders and their habitats from research online.

In our picture we have lots of factors. in our picture we have a food chain the sun the grass the insects and the spider. in our picture we have three biotic thing and four abiotic things. he plants are the producers and the flies and the spider are the consumers.the predator is the spider and the prey are the flies.since the tank was designed for the spider and its prey to survive it can only hold 1 spider and a 2 flies i think thats its carrying capacity.

This Week In Science (carrying capacity and relationship)

this week in science we watched a bunch of videos of animals relationships. we also played a game called oh deer that you have to get a person who has the same thing as you. i dont really remember the instructions. we also played a card game with our groups to learn more.


 this week we learned about mutualism, commenalism and paratism. mutualism means organisms helping one another, commenalism means an organism helping another without the other wanting it and paratism an organism gaining something  and the other gets badly affected by it. together these are called symbiotic relationships.

this week in science: food chain and energy pyramid

   this week in science we made a food chain using animals from our animals habitat. we also made a energy pyramid using animals from our animals habitat we also drew pictures for both of these with our animals. we actually got lots of work.                                                                                                                  
this week in science we learned about energy pyramids and web chains. i learned that the longer an organism is living the less its energy becomes. this week we learned about diffrent type of consumers and producers. we found out that plants are also called autotroph because they make their own food. this week we made our own energy pyramids and web chains including our own animals that we have been researching about.

My Fantasy Habitat

This week in science i learned about biomes, abiotic and biotic things. i learned that bearded dragons are found in desserts. i found out their are cactus in the dessert. ive found out that my animal is an omnivore. i larned that biomes are habitats an biotic is a living thing and an abiotic is non living thing..

this week in science we researched are animal we also had to find their biomes. my animal is a bearded dragon and its biome is an dessert. after this we had to find abiotic and biotic thingb in our animals habitat. when we finished are research we had to draw a picture of our animals in their biomes. we also had to include abiotic and biotic things in our drawing.
