I did this test and i had this water that smells like fart, but anyways i tried to see if the water was lead positive! it turned out negitive lead, i was right. lead is like a poison it can kill children. Good thing it didn't have lead. -> What was your hypothesis (your prediction of what the test will say) my prediction was negitive, i was right.
-> What was the test procedure (what steps did you take to do the test) i took drops and waited 10 minutes to see if the east river had lead.
-> What was the result? Did it surprise you? yes i thought the east river was poison.
