__Group 7__: Willy, Dom, Jared, Jordan hachey( willy wants the word" wimsicle" in this project, so we put it here.)

Purpose: how can a high level of water affect aquatic plant growth, vs a low level of wate affecting aquatic plant growth

Research: [Online] avalible http://fish.mongabay.com/plant_care.htm- this site helped us get a better understanding on what we are studying. ( "Most aquarium plants can be kept in water with a hardness from 4-12 dH, and a pH from 6.5-7.2. For specific species, see the individual descriptions. The water should be kept as clean and clear as possible because free debris can settle on plant leaves or cloud the water, interfering with light intensity. Very few aquatic plant species can survive in brackish water". ) other sections of this site helped us, aswell.

[Online] avalible http://plants.ifas.ufl.edu/guide/temperature.html- this site helped us by letting us know that aquatic plants live in a cooler enviroment. ("while swimming in a lake or pond on a hot summer day, you’ve probably noticed that the temperature of the water down near your feet is much cooler than the water near the surface. This is because radiant energy from the sun is able to heat the water near the surface more efficiently. As long as the sun continues to shine on the surface, the top layer is warmer and, as a result, less dense than the cooler, heavier water below. This layering effect is known as [|thermal stratification]. For many of us, that warm layer on the surface feels pretty good")

Hypothesis: Jared thinks that aquatic plants will have a better growth development in a low level of water, As Dom, Willian, and jordan think it will grow a lot getter in a higher level of water.

Materials that are required: -Two tanks, bowls, or jars- anything to hold the water. - rocks, sand etc- to similate the river system -a theremometer,( both jars should have around the same temperature at all times ) - Any type of aquatic plants. - a water source

Procedure: Step one: Fill the jars with the temperature of the normal enviroment that aquatic plants are used to living in( go down to a local river and take a temperature sample of the water) this will assure that the temperature is not a factor with the plant's growth, because we are only trying to see if they grow better in a low and high level of water.( but before you fill the jars, make sure that you put your rocks and sand, etc... in the jar first)

Step two: put the plants in the both jars.

Step three: Well, theres nothing else you can really do, accpet wate.You should record your analysis( take pictures)

Analysis:



This is what we've seen so far...It's nothing much, but we assume( Dom, Willie, And Jordan) that the plants in the low level of water will propabaly die in 1-2 weeks ( this page will be updated when something happens.)
 * Jared still thinks the plant in the low level of water will still out grow the plant in the high level of water, or not die first.

This is what we've seen after 1 and one half weeks.
