Prattville High School's AP Environmental Science Class Receives Hands-on Experience with the Aquatic Environment at Lanark

Alkalinity, which is a measure of the buffering capacity of water, was measured using a hundred milliliter container.	A student prepares to measure chloride levels.
Results of chemistry analysis was recorded.	Reagents were put in small vials.
Water temperature, which affects dissolved gases, was recorded.	Vials were stoppered and shaken.
Water samples were taken for each analysis.	PHS AP Environmental Science students work together.
Chemical analysis was conducted as a group.	Prattville High School students receive instruction from Alabama Wildlife Federation staff Rebecca Bearden.
The color of the chemical reaction indicated the pH of the water.	Some irises were in bloom at Lanark.
A seiner leads with the lead line.	The bottom of the seine must be kept on the bottom to keep the catfish from getting away.
Everyone is anticipating catfish.	The catfish holding container is ready for deployment.
Channel catfish have spines, and they must be handled with care.
Students make sure the seine does not get hung up on the bottom.
Thanks for the great fun fishing! Mr. Doug Darr Alabama Wildlife and Freshwater Fisheries Division Let's Go Fishing! Where? How? Commit to take someone fishing and be eligible for a drawing. Join Anglers' Legacy!	A PHS student pulls in the seine.
