Consider the hypothesis below and answer the question that follows. adding salt to water increases the water’s boiling point. if you performed an experiment to test this hypothesis, which action would introduce confounding variables into your experiment? you use distilled water sourced from the same place. you add black salt to some specimens and pink salt to others. you add equal quantities of salt in all the water specimens. you use earthen clay pots to store and boil all the water specimens.

1. when conducting a test on what kind of music increases the growth of plants, all of the following would fail to meet to fair test standard except (1 point) using different kinds of plants. giving some plants more water than others. exposing the plants to different types of music. using nutrient-rich soil for one and lesser soil for others. 2. engineering uses scientific thinking to solve real-world problems. (1 point) true false 3. what does it mean to test a hypothesis? (1 point) pass a quiz on other scientists’ results analyze only the results from scientific sources not make assumptions about how an experiment will turn out see if the results of an experiment are what the scientist predicted
