Scientific progress is made by asking meaningful questions and conducting careful investigations.
As a basis for understanding this concept and addressing the content in the other three strands, students should develop their own questions and perform investigations. Write or draw descriptions of a sequence of steps, events, and or observations. Students know examples of diverse life forms in different environments, such as oceans, deserts, tundra, forests, grasslands, and wetlands. Investigation and experimentation a. Repeat observations to improve accuracy and know that the results of similar scientific investigation seldom turn out exactly the same because of the differences in the things being investigated, methods being used, or uncertainty in the observation. Investigation and Experimentation a. Differentiate observation from inference and know scientists' explanations come from partly what they observe and partly from how they interpret their observations.
