Teacher Name: _____Van Wagner______
Topic: ___Stream water testing
LESSON
ESSENTIAL
QUESTION:
Class: _________AP Enviro
Date of Lesson: __Class #51 and 52
Big Idea:
Water continuously moves through the water cycle. Water is essential to living things.
Liquid water makes earth a unique planet.
Fresh water is finite.
Essential Questions:
-Where does pollution come from?
-Is quantitative data/testing more useful that qualitative data/testing?
-What are the advantages of collecting both qualitative and quantitative data?
-Should science be restricted to quantitative research?
STANDARD /
LEARNING
TARGET:
Core standards addressed with this lesson:
7.4.9.A:
Compare and contrast the effect of the physical systems on people across regions of the
United States.
7.4.9.B:
Compare and contrast the effect of people on the physical region across regions of the
United States.
7.4.12.A: Analyze the global effects of changes in the physical systems.
7.4.12.B: Analyze the global effects of human activity on the physical systems.
S11.D.1.3.3: Explain factors (e.g., nutrient loading, turbidity, rate of flow, rate of
deposition, biological diversity) that affect water quality and flow through a water system.
4.8.10.C.
Analyze how human activities may cause changes in an ecosystem.
* Analyze and evaluate changes in the environment that are the result of human
activities.
* Compare and contrast the environmental effects of different industrial strategies (e.g.,
energy generation, transportation, logging, mining, agriculture).
ACTIVATING
STRATEGIES:
Bell Ringer: If your stream has a pH of 5.5, is this acidic, alkaline, or neutral?
(Anticipatory Set)
Answer: acidic
KEY
VOCABULARY:
Atmosphere, troposphere, stratosphere, ozone, radiation,
RESOURCES:
Teacher slide show, demonstration, and lecture.
TEACHING
STRATEGIES:
If we remove a wetland, how could this affect flooding, habitat, and pollution?
Definitions:
Pollution – a condition when some part of the environment is unfit for living things.
Qualitative test – yes / no test
Quantitative test- gives specific amount (quantities)
Ammonia Nitrate – caused by sewage pollution (animals or humans)
pH- acidic or alkaline. Acids dissolve metals into solution.
Chlorine – disinfectant
Hexavelant chromium – used in metal finishing. Carcinogen.
Copper – metal from pipes. High levels dangerous
Cyanide – common in waste water from metal factories
Iron – high concentrations dangerous.. coal mine drainage
Nitrate Nitrogen – agriculture runoff
Phosphorus – agriculture runoff
Silica – very common locally. Damages metal pipes, valves, boilers.
Sulfides – rotten egg smell. Odor is unpleasant.
Students begin Qualitative Stream Pollution lab.
Must wear goggles
Rinse test tubes and caps!
Use pipettes
Exit bell ringer- close notebooks. Pair chare. Define pollution, qualitative , quantitative
Day 2
Bell Ringer
Some of our local streams have tested positive for Ammonia Nitrate. What does this
suggest is getting in to the stream?
Sewage
Complete stream pollution tests.
Students MUST wear goggles entire class.
When done, they are to clean lab stations with sponges and return all test tubes, chem.
Plates, and caps to lab kits. Used pipettes are garbage.
Project blank water pollution Excel spreadsheet on LCD projector. Have each student
group send a representative to the teacher PC to enter their data. Have each student create
data table for all streams and fill in data as it appears on the screen.
Discuss results. Causes? concerns? Treatments?
EXTENDED
Lab report to be written on your research
