| *For this experiment, the independent variable is the age of the houses. The dependent variable is the lead content in the water. This is determined by sending the sample for testing in the lab. The constants (control variables) are the amount of water taken as samples, and the laboratory used for testing. *Visit the new houses (less than 10 years) and collect the water samples. Houses in different residential areas are selected because they will have a different piping path leading from the water source to the house. Before taking any samples, ask the owner of the house if ..... | ||
