=Ideas for Chemistry about what to do about water:=
 * Level of eutrophication (how much oxygen there is in the water)
 * as the enrichment of the water increases, amount of oxygen decreases
 * oxygen depletion could lead to "death" of the water
 * Task: To see how much phosphate there are in the water/lake
 * phosphate is one of the most common chemical (pollutant) found in water
 * phosphate test kit
 * method:
 * 1) collect 10mL of lake water
 * 2) insert the powder into the lake water
 * 3) shake the solution until the powder dissolves in the water
 * 4) move the solution into the case with the supplied color chart and set for 2 minutes
 * 5) compare the color of test strip to the supplied color chart
 * too much phosphate: may lead to eutrophication = death of aquatic life = more polluted


 * data:**


 * #1 and #8 = around the stairs
 * it can be concluded that closer the water is to the stairs, more polluted the water is.
 * higher phosphate level = higher chance of eutrophication
