post 8; this week in science ( fruit flies part 1)

this week in science i came to school only 2/3 days and so yesterday my class mates and i were trying to figure out if how many flies was in a small container flying around and that kind of tricky because if you look at it it would look like a million fruit flies flying around so instead we deiced to try to figure it out in a way that we wouldn't eve have to look at the flies.

so we learned that if we put 3 flies to start with in there if there all adults the females lay 2O eggs a day and it only takes 1 day to lay a egg 7 days in the larva processes 6 days in the pupa and then 2 days to become adults and then they lay 2O eggs a day so in 16 days there should be 323 flies in 16 days in the small container then the process starts again.

This Week in Science (Spider Habitat Design)

 March 28,2011 was the first day of this week in science and we created in our note books a spider habitat in my note book i drew a spider a web ,tress&plants and a rock but as the week went on i found out the habitat had to be sealed with serape so we had to put food in it and keep them alive for a long time. the nexts day we learned that the spider would release carbon and the tree gives the spider gets oxygen from the plants.we also played a game <3

 this week i learned ; carbon and oxygen are exchanged in the biosphere in a dynamic cycle which is
reseruoris- places where carbon is stored &process-relase or fix (capture) carbon
for example-photosynthesis, burning fossil fussil fuels , breathing ect.
