a post about (u guessed it) science!

this week we did 3 simulations, one was with moths, one was with these starburst things and the other was with the gupppies. Then we answered some questions about them on a google doc. Heres the link, (my group was group D) click here ladies and gents. We went over that in class and then we took notes on it.

but those are not the fiirst notes we took this week, we also took notes on adaption which i might have said last time but i dont remember so ill say it anyway :)
here is what i have in my notebook after this week:

Adaption- Changes in the physical structure or behavior of an orhanism that bet suits its environment and develps over time.

Examples of adaption:
•polar bears- white fur to blend in, black skin to absorb warmth
•Skunk- smell
•whale- breathing system
•birds-hollow bones
•penguins- oily surface, fins, webbed toes
•stick bug- camoflouge, looks like stick
•turtle- shell
•chamelion- changes color
•cheetah-speed
OK so there are like millions more but ill just leaveyou with that.

Processes by which we get adaptions:
+adapting
+evolving
+development

Here are notes from the simulation:

•If the environment changes too fast the organism will not be able to adapt
-adaption occurs over time
^natural selection (we will be startiing that unit soon)

•If you have an organism not suited to the environment they will die out

•if they ARE siuted to the environment they are more likley to survive and reprodduce

•change is gradual for a population

----then we had a picture of the relationship between the predators population and the prey's and it looked like a double helix---

•populations are "static" or "dynamic"
-static: constant
-dynamic: always changing
•if population is too high: -limited resources
-disease
•prey population low---> predators die----> prey goes up

OK the end!!! we will have more population notes on monday i think and i believe we will be starting natural selection next which apparantly is really intense.

so

happy mothers day!!! <3

enjoy your weekend

commen on my blog! ;)

Ok well HUG! HUG! HUG!

bi bi!!!
