Well this week in science we observed the changes that occurred in our terrariums. I noticed that there were flies in ours. Question is how did they get in there in the first place?! if the terrarium is completely sealed and nothing is able to get out especially get in. so that's a question that i have and i want to solve. we also observed some fruit flies that David brought in. he said we are going to breed them so they can be food for our spiders.we looked at the under a dissecting microscope and studied them closely. i noticed that for each stage of their life they look different. I wasn't able to find an egg but i saw the larva,pupa, and the adult flies. the larva and pupa look different, the larva is a lighter color and moves differently than the pupa. Then on Thursday we had to solve the problem of How many fruit flies would there be after 3 weeks if we put 3 fruit flies in a jar. i was absent but i copied the noted from my classmate and figured out that there would be 180 fruit flies in 3 weeks.
I learned what changes happened i our terrarium. there are some flies that appeared out of nowhere ! and i don't even know how they got there. I also learned a lot about fruit flies. I learned about their life cycle and what they look like at each stage of their life. I also learned that it takes them 16 days to make babies and they can lay up to 20 eggs. Another thing i learned is that female fruit flies are a bit bigger than the male fruit flies and that their scientific name is Drosophila Melanogaster.
This is the life cycle of a fruit fly.
