General theme

· Population growth

· Carrying capacity

· Competition for resources

· Interest specific: fertilizers, nutrients, space in the cup,

· Limited resources?

· They grow on the surface they cant grow below water, surface are of the water needs to be large enough to be able to support water

· References what kind of references did u think about? Something talking about why we are using them, using our subject/plant for experiment, something about population growth,

· Look at population growth specifically exponential and logistic curves you

· Use insects

· Flowers

· beatles

· anything to make a case for whatever hypothesis you may have!

· How to estimate K: take the last count of whatever population you are looking at,

· JR: Your cuurents counts are 19 22 22 21 19 21

· Things may level off things may change in a week

· Use that table

· Break up that formula into various parts based on the counts that you will get next week

· You want to estimate what jr

· You will do that for every cup you have and put that in the files that I send to you

· Three figures

· 1.Class average growth curves

· 2. A and o curves

· 3. k& R

· How are you going to graph this: BAR graph to show the differences to see if it actually is significant or not include the air bars to see if its significant

· Is there Another test that is appropriate: Yes

· T is test for two groups

· Bio nova is for 2 or more /more rigorous test anyway
