• Rotifer can be found in most freshwater (lake bottoms, rivers, or streams) enviornments and some soil.
• They are small in size and have soft bodies.
• The body of rotifer consists of four basic regions, head neck body and feet.
• The head carries a corona of cilia that helps the water get into the mouth.

• Because they are so small people have not really heard about there exsistance.
• They have less then 1000 cells
• They get around using the corona (crown of the cilia)
• some walk with head and foot
• There feet have a sticky substance that allows them to attach to surfaces.
• They also use the corona to get food in there mouth
• Rotifers are so transparent all there organisms can be observed easily
• They have one or two light sensitive red eye spots
• They have a variety of body shapes that to suit the different enviornmental conditions
• They can be found anywhere with water even gutters or birdbaths
• The corona can vary in design. It is not always used for locomotion.

• The foot has two toes on the bottom.
• The head has a large cup shaped mouth surrounded by cilia.
• The cilia is used to trap food and move around through the water
• They attach to plants when they grow up
• The rotifer is transparent so you can see its food inside
• They go into a clear tube like turtles and its shell and thats why they are transparent
• To eat they extend there body out of the tube
• There food includes, algae, small crustations, and pieces of plants
• They pretty much eat anything that fits in there mouth
• Rotifers do not reproduce they make eggs by themselves
• Eggs are very tough and last through the winter. They wont dry out.
• populations of rotifers can vary
• there preditors include: aquatic insects, crustations, small fish and anphibians
• they are in the phylum science classification

some notes i forgot to post
http://ga.water.usgs.gov/edu/acidrain.html
• Not pure acid falling form the sky
• “atmospheric moisture” mixed with “elements and gases” to form a rainfall that has more acid in it than normal
• pure water has a level of 7 pH
o acid rain water has less than 6 and even can go down to the 4’s on the north eastern side of America (although the north eastern side of America does have one of the lowest pH levels in America, but they do not cause it. It is mostly the factories in places like Ohio that get carried over to the north eastern side.)
• acid rain is caused by
o burning of fossil fuels (SO2 or sulfur dioxide)
• coal
• oil
o exhausts from cars (this causes nitrogen oxides to form in the air. It also causes other gases to form, like: sulfuric acid and nitric acid .
• the affects of acid rain
o environments can adapt to certain amounts of acid rain
• this is because some soils have bases in them like limestone (limestone has a greater pH than 7) and it can balance out the pH.
• Put other places like the rocky mountains are not like this so it does actually have an effect of the environment
These are the places we are worried about

intern application (take 2)
My experimental study seeks to find the effect of acid rain on zooplankton. The independent variable I will be studying is acid rain. Numerous things cause acid rain, for example, gases from factories, cars, planes and many more things produce acid rain. These gases are carbon dioxide, carbon monoxide, chlorofluorocarbons, hazardous air pollutants, lead, nitrogen oxides, ozone, particulate matter, sulfur dioxides and volatile organic compounds. The jet stream carries these toxic gases throughout our atmosphere and is then caught into clouds. The gases then dissolve into rainwater to form acid rain. Later when it rains local bodies of water have a major affect on the earth. These affects include the following disintegrating trees, poisoning water and much more. In result of acid rain many organisms living in environments that are being affected by acid rain can get poisoned, which may lead to death.
Plankton and other forms of small organisms and plants, such as algae are the foundation of every food chain. It is necessary to keep this plant safe. For organisms that depend on zooplankton to live, there will be some problems due to the increases in pollution, which results in acid rain. The oceans food chain goes like this: phyto plankton at the bottom, then zoo plankton, then fish larvae, then smaller fish, then larger predators. All of those animals (other than the phyto plankton) eat the zooplankton. So this means if the acid rain poisons the zooplankton, most of the animals in the sea but be terribly endangered.
That was part B. I know it is a little short but i think the info that i have in there is very good. Quality over quantity!

Today in class, I worked on getting some research for acid rain and zooplankton. I then posted it on blogger. For tonight I want to start the actual writing on my research paper.
acid rain
ware or how am i going to make acid rain? Because if i do make it, it probably wont be exactly like what acid rain is...
gases that cause acid rain

Recap
I haven't posted yet so this is my first post...
I have met with Ms. Weissman twice so far they were:
1. what my topic should be
2. how to take up some more space, or get more words, for question B of the Intern Application. It helped me a lot because it contains more than half of the words for B.
3. the first part of my question B was completely wrong. That was the answer for another question. I was rejected so i just have to do that over and then I will be accepted. I can keep the same topic.
