Research question: How does movement upstream affect water turbidity and nutrient content, and how does this affect aquatic plant life?
Variables:
Indepentent(water chemistry and turbidity)
Dependent(plant life)
Controlled(same depth of water "4 cm" and same testing equipment")
Equipment: Colorimeter,
5 cuvettes,
2 pipettes,
15 viles,
a camera,
15 nitrate and nitrite papers,
15 phosphate papers,
turbidity testing kit,
computer,
meter stick,
permenant marker and bucket.
Hypothesis: More plant life will be found upstream because light transmition will be higher because of less sediment.More plant life will be found downstream because increased sediment will lead to higher nutrient content. Plant life will therefore remain constant.
Conclusion: The farther you go down stream,the content of nitrate significantly increases,phosporate content doesnt have any actual correlation,transmittance decreases the further downstream the one goes. The NTU value decreases as one goes downstream which means that the turbidity of the water increases as one goes downstream, no difference in plant life( reference the pictures).
