taking water samples from a pond
Collect samples from a pond to see if the pH of the water is within a safe range for fish.
What are the pH values of the 5 samples you took?
What is the average pH of these samples in this first trial?
The recommended pH of a pond is between 6.5 and 8.5. Is it a safe pH for the fish in the pond? Would you make any adjustments to the water?
Perform another trial by restarting the applet above. What is the average of the new 5 samples?
How would you change this sampling set up to get a more accurate pH reading?
