Gizmos Student Exploration: Unit Conversions 2 – Scientific Notation and Significant Digits

LAB 1 What patterns do you observe based on the information in Table 4? - correct answers At first as the amount of oxygen increases, so does the amount of fish. When the oxygen reaches 14 parts per million, the number of fish observed decreases, but then begins increasing again. LAB 1 Develop a hypothesis relating to the amount of dissolved oxygen measured in the water sample and the number of fish observed in the body of water. - correct answers If more oxygen is added to a body of wa...
