Explain how scientific knowledge is developed when people make observations about the natural world.

Scientific knowledge is developed only when you make an observation about the natural world because without an observation, you will not question anything which mean there will be no scientific knowledge about the world around us.

Explanation:

Scientific knowledge is built as people come up with hypotheses and theories, repeatedly test them against observations of the natural world, and continue to refine those explanations based on new ideas and observations. Observation is essential to the process of science.
