Post 8: This Week in Science (Fruit Flies)

This week in Science we observed and made some notes of the things we notice and wonder in our habitat.Also we made notes of some Fruit flies that we saw.In my habitat i noticed that have a lot of flies and i wonder how the flies get there.In the fruit flies jar i noticed the different stages of the fruit flies but i didn't saw the egg.I only saw the larva,pupa,and the adult.The next day we solve a problem making our own hypothesis.We need to find how many fruit flies would be after  3 weeks if we put 3 fruit flies in a jar.My hypothesis was that after 3 weeks would be 180 fruit flies.





This week in Science i learned a lot about fruit flies.The 3 stages of life in drosophila melanogaster(Fruit flies) that are:egg,larva,pupa,and adult.Also i leraned that to make babies the fruit flies takes 16 days.In one day they have 20 eggs.I also learned that the females fruit flies are more bigger than the males  fruit flies.

Post 7: This Week in Science (Ecosystems)

This week in Science we design our habitat.After that we prepared our tank to go to the community garden.In the community garden we collected things that we can use for our tank.We found worms,leaves,and little rocks and put in the tank.Then we observed at other tanks to create questions about the tanks.The next day we correct our test of the ecosystem to make connection to our habitat.The last day we research information of one of the organism of our habitat.And we start design our map of the habitat.




This week in Science i learned about leaves by research information about it.Leaves eats water and oxygen and get it energy from the sunlight.Herbivore animals eats the leaves.The leaves are a producer because it produce its own food.In the trophic level,leaves are the first level.And their environment is tropical.




 I'm still unsure about how the animals in my tank died.And how other animals in the ecosystems and other tanks still alive.I also unsure of how the spider is going to survive in the close tank.I'm curious of what spiders eats.And i want to know from where the spiders gets their energy.


This two pictures shows how we prepared our tank and how we were looking for organisms in the community garden.

Post 6: This Week in Science (Spider Habitat Design)

This week in science the first day we search information about the spider Pholcidae that is the spider that we are going to use to create the habitat.We design in our notebook ideas we have to create the habitat.The next day we shared our  ideas we our group to create the design of the habitat.We started design our habitat.A side view and a top view.And the last day we play a game to understand the Carbon-Oxygen Cycle.



This week in science i learned about our new project of design our own habitat for a spider.I learned what is in a spider habitat.What they need to survive like food and etc.Also i learned the cycle of carbon and oxygen playing a game.Carbon and oxygen are exchanged in the biosphere in a dynamic cycle:reservoirs and processes.
