- A well-designed experiment will contain both positive and negative controls. Which of the following is a false statement? Choose one from the following: (A) a positive control experiment is missing some of the components of the experiment and should give a negative result (B) a positive control experiment contains all of the components of an experiment and should give a positive result (C) a negative control experiment is missing the element being tested and should give a negative result (D) if there are multiple components of an experiment, there should be multiple negative controls (E) if a negative control experiment give positives results, it is likely that the experiment is contaminatedarrow_forwardYou observe that every time your neighbor, who always wears a yellow hat, walks out his front door, he gets dive bombed by a crow. From this observation, what is a testable hypothesis? What is your prediction based on your hypothesis? Please design an experiment to test this hypothesis and prediction. You must identify the independent and dependent variables, as well as at least 2 control variables, and your experiment must contain an experimental group and a control grouparrow_forwardWhat are three important thing you will consider when settting up an experiment to investigate a phenomenon?
