Observations are things or events that are noticed. A good observer uses all the senses, not just sight. See how good an observer you can be.
(NOTE: Chemists rarely use their sense of taste in the laboratory - it could be dangerous. Few early chemists reached retirement age.)
A good scientist makes a careful record of what is observed.
Scientists also try to explain why things happen in terms of what they see and what they already know.
For all these activities keep a simple record of your observations and explanations.
