The student said the animals had killed several chickens that the school was raising in a shed behind the building and said the teacher made students join in drowning the animals.
As one of the students recorded cell phone video, Brewton and the students plunged them into the water and sprayed them with a hose to kill them.
The teacher has worked at the school since 2006.
A Forest High School agriculture teacher, Dewie Brewton, was placed on paid administrative leave after he allegedly drowned three caged "nuisance" animals as part of a classroom demonstration. Took the cages, filled up large trash cans full of water and had the children drown the raccoons in the cages inside the water.
'It made me sick, ' the mother, who asked to remain anonymous, told WKMG.
The mother of the student who filmed Brewton's class said her son was in tears when he revealed what had happened to the two raccoons in agriculture class on Monday. "It's awful. It still does make me sick to my stomach". "It's awful. It still does make me sick to my stomach", said the mother, who did not want to be identified.
"They finally took the cage out of the water, and they trapped it into another smaller cage, where the top of the cage would go down into the water", he said. "They should have trapped the animal and had somebody take them and relocate the animals".
The school board made a public statement letting the district know that, although the authorities indicate the teacher may not have broken the laws, "his actions before students are certainly questionable".
Florida Fish and Wildlife Officials say they're looking into it and said, "FWC officers are investigating to see the legality of the issue that occurred". The commission's findings will be sent to prosecutors, who will determine if the teacher will face charges.
Forest High School's Future Farmers of America Alumni Chapter has since rallied around Brewton, who is the group's adviser.
The woman whose son recorded the video said that after they had killed the raccoons the students killed an opossum "just for sport".
'I don't think that's the way to treat any animal, ' she said. He has always gone above and beyond his call of duty to ensure that his students had everything they needed'.
"He has spent late nights, weekends and has provided around the clock support for his club and for his school", a post on the Forest High School FFA Alumni page reads.
