Slide3
Point & Non-point Source Pollution
Create a Venn diagram that compares and differentiates between point and nonpoint source pollutions. Make sure your Venn has
2
similarities and at least 4 differences on each side.
Slide4
pH
What is it?
Why is it important?
Acceptable level/conditions
What causes water to become too acidic? Why?
What causes water to become too basic (alkaline)? Why?
How does the pH level of a body of water influence what organisms live there?
Slide5
Temperature
What is it?
Why is it important?
Acceptable level/conditions
Explain 3 other indicators that are affected by temperature.
Why is colder water generally better for aquatic life?
Slide6
Dissolved Oxygen
What is it?
Why is it important?
Acceptable level/conditions
Does cold water hold more or less dissolved oxygen? Is this good or bad? Explain.
What 3 factors can influence dissolved oxygen levels?
Slide7
Phosphates & Nitrates
What is it?
Why is it important?
Acceptable level/conditions
Slide8
Bio-indicators
What is it?
Why is it important?
Acceptable level/conditions
Give 3 examples of bio-indicators and explain how each one tells us about the health of the environment.
Slide9
TurbidityColor, Sediments & Hardness
What is it?
Why is it important?
Acceptable level/conditions
What are 2 causes of increased turbidity?
Explain how dissolved oxygen decreases with increased turbidity.
Draw a diagram of 3 samples of water with different turbidities.
