Facts, Observations, and Opinions
Science is an inherently objective topic, as it requires facts to explain the world.
Facts are information that are true.
Facts come from data and results collected from observations and experiments.
Data is factual information that isn’t affected by opinions or bias.
When conducting experiments, scientists can use observations and analysis to collect facts and predict what happens in the world.
