Answer:

Observation- It is a method that we observe our experiment while days pass by, and see changes.

Ex. I observed that the flower I planted in a pot grew fast.

Experimentation- This method is where you will be able to identify the difference of your experiment.

Ex. I planted 2 plants, one at soil and one at pots. Days passed-by and I see that the plant on soil grew faster than at pots.

Question- This method is where you will be asking questions about your experiment.

Ex. Did I water the plant enough on soil so it grew faster than the plant on pot?
