Malathion is a pesticide that kills flies within 30 minutes — a clear example of how harmful chemicals in the environment damage living things. This project tests whether activated carbon can neutralize that harmful substance. You spray malathion on overripe bananas and place them in aquarium tanks with flies. Some bananas also get a coating of activated carbon solution at different concentrations. You then count how many flies survive over one hour to see whether higher doses of activated carbon protect them from the pesticide's deadly effects.

Malathion kills flies within 30 minutes on its own — but activated carbon's tiny holes can trap toxins like this pesticide before they cause harm. In this experiment, overripe bananas are sprayed with malathion and placed in aquarium tanks with flies. Some bananas also get a coating of activated carbon solution at different concentrations. You count how many flies survive over one hour to see whether higher doses of activated carbon protect more flies from the pesticide.

Malathion is a pesticide that kills flies within 30 minutes on its own. The question here is whether activated carbon can neutralize it. You spray malathion on overripe bananas placed in aquarium tanks, then coat some bananas with activated carbon solution at different concentrations. Ten flies go into each aquarium, and you count how many survive every 10 minutes over one hour. As the concentration of activated carbon increases, the results show whether higher doses protect more flies from the pesticide.

Malathion kills flies within 30 minutes on its own — a clear toxic effect. The question is whether activated carbon can neutralize the pesticide and allow more flies to survive. You spray malathion on overripe bananas and place them in aquarium tanks with flies. Some bananas also get a coating of activated carbon solution at different concentrations. After one hour, you count how many flies are still alive. The results show whether a higher dose of activated carbon provides more protection from the pesticide.

When molecules stick to the outer surface of a solid instead of soaking in, that process is adsorption. Activated carbon works this way — its surface holds onto toxins rather than absorbing them. This experiment tests whether spraying overripe bananas with activated carbon solution can protect flies from malathion pesticide. You coat bananas at different concentrations of activated carbon, release flies into aquarium tanks, and count survivors over one hour. The results show whether higher doses of activated carbon protect more flies by trapping the pesticide on its surface before it causes harm.
