- - - - the 4 parameters
        
        Turbidity - Measure of the relative clarity of the water
        
        pH - measure of the alkanity or the acidity of a aqueous solution
        
        Temperature -> Average kinetic energy in water molecules
        
        Dissolved oxygen - Amount of oxygen dissolved in a given amount of water, at given temperature and atmospheric. Measured in mg/l or ppm.
        
        Methology of collection for these 4 parameters: 3 locations (refer to sampling, preferabbly one at input, one at output, one far from these two, take 3 readings, calculate average, dip clean container just below water surface away from the bank, without disturbing sediments at bottom,. rinse before filling for testing. wear gloves keep hands from face
    - - Things to take note of 1. Draw the sketching frame + border 2. Draw only the key features related to the GI inquiry question. Try to keep in proportion. 3. Draw the orientation and the legend (If symbols/shading were used)
    - - More accurate than the standard tests
- - - - What do we record
        
        Hearing
        
        Smell
        
        Touch
      - Key pointers
        
        Specific -> Instead of "Lots of trash" write "Obeserved 4 plastic bottles floating near drain at 10.15 a.m."
        
        Location & Time: always record where and when this took place
        
        Stick to the facts: record sensory observationsm, not wild guesses
        
        Combine with pictures -> Ensure field notes match with the annotated photos (and vice versa)
- - - - Uses the idea of intervals (Counts the percentage of weeds in an area along the river bank every 500 m works although you dont know the total population size (Total number of plants)
    - - Uses a random number generator (egs assign the students numberss from 1-30, use random number generator to pick 10
        
        Used when you have an idea of the total population size
- - - - What affects it
        
        Human error/ Mishandling of equipment (Refer to GI package for specific problems for each of the parameters
      - How to avoid it
        
        Refer to the GI package for specific solutions for the specific problem
    - - What affects it
        
        Space (Only taken from one site)
        
        Time ( Taken in inconsistent intervals
      - How to avoid it + Why does the solution work (Make sure solution matches the problem)
