Check Your Understanding

1. What goes in an observation journal?

Answer: Facts about what you observe — what you see, hear, count, or measure. Not opinions or feelings, but specific, factual descriptions.

2. What is the difference between an observation and an opinion?

Answer: An observation is a fact you can verify: 'There are 12 red cars in the parking lot.' An opinion is a judgment: 'Red cars are the best.' Data science uses observations.

3. Why do scientists keep journals?

Answer: To record exactly what they observe so they can look back, find patterns, and share their findings with others. Memory is unreliable — writing is permanent.

4. If you observed the sky for a week, what patterns might you find?

Answer: The sun rises and sets at similar times, clouds appear more on some days, the sky changes color at sunset. You might notice weather patterns over the week.
