Study Tip
The same way a person may cast a shadow over another person when they stand under the sun, planets or celestial bodies that have aligned themselves cast shadows over one another as well.
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.
Study Tip
Think about something you’ve read in a magazine, whether it is an article or a horoscope. Can you identify which are facts, and which are not?
Concept Check
- What is the difference between facts and data?
