In this six week lab we discovered many important things. We found that most of the acidic pH levels quickly killed the duckweed along with most of the alkaline pH level liquids. With the alkaline levels of pH we found that soap and bleach did kill the duckweed fairly fast and killed all of the living organisms within the water and on the duckweed. With the acid levels of pH we discovered that the duckweed and living organisms were also killed quite quickly in the liquids coffee and lemon juice. In the one neutral liquid, sink water; the duckweed was not killed but, the living organisms died. This experiment did not go exactly as we thought it might but all in all we discovered what we wanted to know.
Duckweed is a plant that grows in still or mostly still water such as lakes and ponds. Duckweed grows rapidly and can easily cover the top of a pond and black out sun and air causing most animals or microorganisms to die. In the experiment the attempt to find out how duckweed would act based on different pH levels. Our goal was to see if plants can grow with high or low levels of pH added to the pond water it was previously in. This experiment was to see if duckweed could grow in other conditions, and see if it would thrive or die. The expectations are that most duckweed plants

In the one neutral liquid, sink water; the duckweed was not killed but, the living organisms died. By week two of the experiment all of the living organisms were dead in the different pH levels except of course the original pond water and duckweed we kept. This is what our data showed by the end of the six
